Also removed the ``ignore this error'' message from the - chat scripts since it's no longer marked as an error. - - * sys2.unx (fsserial_set): Ted Lindgreen: if CRTSCTS is defined - and turned on, then don't turn on IXOFF. - - * uucp.h, log.c, uucico.c (fdo_call, faccept_call): Ted Lindgreen: - report the port name and (for incoming calls) the login name in - the log file. - -Sat Mar 7 10:00:47 1992 Ian Lance Taylor (ian@airs.com) - - * port.h, prtinf.c, sys2.unx (fsserial_lockfile, fsserial_lock): - Peter da Silva: added ``lockname'' command to ports to permit - specification of the file name to use when locking. - - * sys1.unx (usysdep_detach): let setpgrp fail silently. - - * sys2.unx: always include <sys/ioctl.h> if it's present on the - system. - - * time.c (btimegrade, cmax_size_now): removed extraneous - semicolons. - - * sys2.unx (fsserial_lock, fsserial_open, fsserial_close): support - TIOCEXCL locking. - - * sys2.unx (fsserial_open): preserve unknown bits in c_cflag when - using HAVE_SYSV_TERMIO or HAVE_POSIX_TERMIOS. - - * prot.h: never included more than once. - -Fri Mar 6 21:53:28 1992 Ian Lance Taylor (ian@airs.com) - - * uucp.h: Eric Ziegast: some systems don't define EXIT_SUCCESS or - EXIT_FAILURE in stdlib.h. - - * uucp.h, uutime.h, uucico.c (fuucp), sysinf.c (uinittimetables, - uaddtimetable), uuchk.c (main, ukshow_size, ukshow_time, - qcompress_span), time.c (all new): rewrote time routines - completely for consistency and simplicity. Fixed bug causing - incorrect maximum possible transfer size. Added new file - uutime.h. - -Wed Mar 4 10:06:13 1992 Ian Lance Taylor (ian@airs.com) - - * sys2.unx (fsserial_lockfile, fsserial_lock, fsysdep_modem_open, - fsysdep_direct_open, fsysdep_modem_close, fsysdep_direct_close): - Petri Helenius: if the open failed on a serial port, the lock - files were not removed. - - * config.c (igradecmp): the local variables in igradecmp have to - be integers; signed characters might not work correctly (although - they would in all normal cases). - - * sys4.unx (fsysdep_has_work): Johan Vromans: set *pbgrade - correctly if we still have work left over that we haven't looked - at yet. - - * tstuu.c (main, uchoose, fwriteable): Roberto Biancardi: use poll - if we haven't got select. - - * uucico.c (zget_uucp_cmd): Michael Haberler: some systems send \n - after Shere, rather than a null byte. - -Tue Mar 3 01:03:22 1992 Ian Lance Taylor (ian@airs.com) - - * uuxqt.c (main, uqdo_xqt_file): permit local executions, don't - get grade out of system dependent file name. - - * sys4.unx (fsysdep_get_work): Bob Denny: warn if we can't open a - command file. - - * v2.c (uv2_read_systems): Jeff Putsch: infinite loop when reading - time string. - - * uucp.h, sys1.unx, sys2.unx, sys3.unx, tstuu.c, configure.in: - Thomas Fischer: some NeXT compatibility stuff: removed externs of - sleep and alarm, included <libc.h> in uucp.h. - - * uucp.h, port.h, uucico.c (zget_uucp_cmd, zget_typed_line), - port.c (cdebug_char, udebug_buffer), chat.c (icexpect, fcsend, - fcphone), log.c (ulog): Michael Richardson: added LOG_DEBUG_START, - LOG_DEBUG_CONTINUE and LOG_DEBUG_END to allow a debugging line in - the log file to be built character by character. Used this new - feature in chat script debugging, rather than having each - character appear on a separate line. Added fPort_debug variable - to control port debugging. - - * uustat.c (fsquery, fsquery_system, fsquery_show): handle - execution files queued up for the local system correctly when - using -q option (they still don't show up on any other option). - - * uucp.texi, protg.c (fgstart, fgshutdown): Aleksey P. Rudnev: - added remote-window and remote-packet-size 'g' protocol - parameters. Reset the parameters to their default values in - fgshutdown. - - * sysh.unx, sys2.unx (fsserial_read, usalarm), sys1.unx - (usset_signal, usysdep_detach), uucico.c (main): overhauled - fsserial_read yet again. The timeout passed in is now an absolute - bound. A special SIGALRM handler does some wierd stuff to avoid - any possible race. - - * config.c (uread_config), sysinf.c (uiread_systems, - fcallout_login, fcheck_login), prtinf.c (ffind_port, - fread_dialer_info), chat.c (fctranslate), uucico.c (faccept_call): - T.

William Wells: don't arbitrarily - extend read timeout. - - * uux.c (main): check iSignal before entering fread, since the - user may have hit ^C earlier in the program. - -Sun Mar 1 23:39:33 1992 Ian Lance Taylor (ian@airs.com) - - * policy.h, uucp.h, sysh.unx, sys2.unx (fsserial_lock, - fsysdep_modem_close, fsysdep_direct_close), util.c (strlwr), - configure.in: Marc Unangst: added HAVE_SCO_LOCKFILES configuration - parameter to force lock file names to lower case. - -Fri Feb 28 00:07:12 1992 Ian Lance Taylor (ian@airs.com) - - * system.h, uucico.c (faccept_call, fdo_xcmd), uuxqt.c - (uqdo_xqt_file), uux.c (main), uucp.c (main, ucspool_cmds), - sys3.unx (zsysdep_spool_cmds), uux.1, uucp.1: added -j switch to - uucp and uux to display the jobid of the spooled job. - - * uucp.h, system.h, sysh.unx, uucico.c (fuucp, fdo_xcmd, - fok_to_send, fok_to_receive), uuxqt.c (uqdo_xqt_files), uux.c - (main, uxcopy_stdin), uucp.c (main), file.c (freceived_file), - config.c (fin_directory_list), sys1.unx (fsysdep_file_exists, - fsuser_access, fsysdep_in_directory), sys3.unx (esysdep_open_send, - fsysdep_move_file), sys5.unx (fsysdep_xqt_check_file): Chip - Salzenberg: recheck file access permissions before sending, to try - to avoid symbolic link games. Check that the user has search - access on all directories down to the file, and read or write - access to the file or directory itself. Check in uucp and uux as - well as uucico, to provide early messages. Check the standard - input file in uuxqt. Be more careful about creating files in the - spool directory. This eliminates all security problems I know of, - except for a very short race in fsysdep_move_file. - - * sys3.unx (esysdep_open_send): give an error message if we try to - send a directory (used to just fail silently). - - * system.h, sysh.unx, sys1.unx (usysdep_detach, ussignal, - fsysdep_catch, usysdep_start_catch), sys2.unx - (fsysdep_modem_end_dial, fsserial_read), uux.c (main): T. William - Wells: fsysdep_catch obviously must be a macro, since it calls - setjmp. Also TIOCNOTTY sets the process group to 0, so we don't - have to fork before calling it. - -Thu Feb 27 00:08:09 1992 Ian Lance Taylor (ian@airs.com) - - * sys1.unx, sys6.unx, sys7.unx: added some extern definitions. - - * configure.in, uucp.h, system.h, sysh.unx, uucico.c (main, - ucatch, uabort, zget_typed_line, zget_uucp_cmd), uuxqt.c (main, - uqcatch, uqabort), uux.c (main, uxcatch, uxrecord_file, uxabort), - uucp.c (main, uccatch, ucrecord_file, ucabort), uustat.c (main, - uscatch), uulog.c (main, ulcatch), uuname.c (main, uncatch), - uucheck.c (main, ukcatch), log.c (ulog_fatal_fn, ulog, - ulog_close), tstuu.c (main, uchild, uprepare_test), sys1.unx - (usysdep_initialize, usysdep_detach, usysdep_signal, - fsysdep_catch, usysdep_end_catch, ussignal, fsset_signal, - fsysdep_run, raise), sys2.unx (usalarm, usysdep_pause, - fsserial_lock, fsserial_open, fsysdep_stdin_close, - fsysdep_modem_close, fsysdep_modem_end_dial, fsserial_read, - fsserial_write, fsserial_io), sys5.unx (fsysdep_execute): T. - William Wells: overhaul to support detaching from the terminal and - completely reliable signals. uucico now calls usysdep_detach at - various points; new option -D prevents detaching. The signal - handling code all goes through usysdep_signal, fsysdep_catch and - usysdep_end_catch. A signal now just sets iSignal, which is - checked at various points, notably in the port routines and in the - main loops in uucico and uuxqt. - -Tue Feb 25 10:59:23 1992 Ian Lance Taylor (ian@airs.com) - - * protg.c (fgwait_for_packet): Bob Denny: reset the count of - timeouts only when data is recognized, so that we aren't fooled by - a sequence of imperfect echoes. - - * sys5.unx (zsysdep_get_xqt): Bob Denny: don't warn if opendir - gets ENOENT. I think POSIX requires ENOTDIR, but what can you do? - -Mon Feb 24 14:37:10 1992 Ian Lance Taylor (ian@airs.com) - - * uucico.c (main, uusage): don't treat an extra argument as a port - name. - - * sys3.unx (esysdep_truncate): Roberto Biancardi: support F_CHSIZE - and F_FREESP in esysdep_truncate. - - * configure.in, sys2.unx (fsserial_read, usysdep_pause): Roberto - Biancardi: use poll to sleep less than a second if we haven't got - anything else. - - * v2.c (uv2_read_systems, fv2_find_port), bnu.c - (ubnu_read_systems, fbnu_find_port, fbnu_read_dialer_info), - uustat.c (fsworkfile_show): Roberto Biancardi: skip spaces and - tabs after doing a strtok ((char *) NULL, ""). - - * copy.c (fcopy_file), sys1.unx (esysdep_fopen), sys2.unx, - sys3.unx (esysdep_open_receive, esysdep_truncate, fsdo_lock, - fscmd_seq), sys5.unx (fsysdep_execute), sys7.unx, tstuu.c: John - Theus: some systems use <sys/file.h> instead of <fcntl.h>. Also - changed the code to call creat instead of open when appropriate. - Should now work on V7, with the exception of O_NONBLOCK and - O_NDELAY in sys2.unx and tstuu.c. - - * uucp.h: John Theus: if we don't have vprintf, ulog is defined - without an ellipsis, so don't declare it with one. - -Sun Feb 23 14:45:53 1992 Ian Lance Taylor (ian@airs.com) - - * uucp.h, system.h, bnu.c (ubnu_read_systems), config.c - (fin_directory_list), sys1.unx (fsysdep_in_directory), sys5.unx - (fsysdep_xqt_check_file), uucp.c (main), uuxqt.c (uqdo_xqt_file), - uucico.c (fdo_xcmd, fok_to_send, fok_to_receive), tstuu.c - (uprepare_test): only permit files to be received into directories - that are world writeable. Check for this in fsysdep_in_directory, - with a new argument. Changed calls appropriately. In tstuu - create /usr/tmp/tstuu as world writeable. - - * bnu.c (ubadd_perm_alternate): Doug Evans: after all that, I got - it wrong: WRITE only applies to remote requests. - - * uucp.h, uucico.c (fuucp, fdo_xcmd, fok_to_send, fok_to_receive), - uuxqt.c (uqdo_xqt_file), uuchk.c (ukshow), sysinf.c - (uset_system_defaults, tialternate), sys5.unx - (fsysdep_xqt_check_file), bnu.c (ubadd_perm_alternate): fixed READ - and WRITE handling to match BNU semantics. Added - zcalled_local_send, zcalled_local_receive, zcalled_remote_send and - zcalled_remote_receive fields to ssysteminfo structure for this, - and handled them in all the appropriate places. - -Sat Feb 22 22:30:59 1992 Ian Lance Taylor (ian@airs.com) - - * Complete overhaul of configuration to use automatic shell - script. Eliminated conf.h, now generated by configure. Renamed - Makefile to Makefile.in. Added policy.h for administrative - decisions and other choices which can not be made automatically. - Many changes to many source files, none having to do with code. - -Thu Feb 20 17:57:55 1992 Ian Lance Taylor (ian@airs.com) - - * uucico.c (fdo_call): Chip Salzenberg: some systems truncate the - Shere= machine name to 7 characters. - -Wed Feb 19 14:36:31 1992 Ian Lance Taylor (ian@airs.com) - - * sys7.unx (fskill_or_rejuv): make sure that only the submitter or - the superuser is permitted to cancel (or rejuvenate) a request. - - * system.h, sysh.unx, sys3.unx (zsfile_to_jobid, zsjobid_to_file), - sys4.unx (zsysdep_jobid), sys7.unx, uustat.c, Makefile, MANIFEST: - wrote uustat. Changed CSEQLEN in sys3.unx from 5 to 4. Added - several new system dependent functions, mostly in sys7.unx. - - * system.h, sys1.unx, log.c, file.c, chat.c, protg.c, uucico.c: - rearranged the time functions for the convenience of uustat. Made - isysdep_time take an optional pimicros arguments. Renamed - usysdep_full_time to isysdep_process_time, and made clear that it - need only work within a single process. Changed usysdep_localtime - to take a time returned by isysdep_time rather than always use the - current time. Changed the calls as appropriate. - -Tue Feb 18 14:03:19 1992 Ian Lance Taylor (ian@airs.com) - - * uuxqt.c (main): pass fdaemon argument correctly to - usysdep_initialize. - -Mon Feb 17 17:09:16 1992 Ian Lance Taylor (ian@airs.com) - - * uuxqt.c (uqdo_xqt_file): T. William Wells: make sure sh uses - absolute path of command, rather than relying on PATH. - - * sys5.unx (zsysdep_find_command): Michael Nolan: allow full - command name to be specified by remote system, not just basename, - if command is not in path. - - * log.c (ulog): don't use headers when outputting to terminal. - - * sys2.unx (fsrun_chat): Bob Denny: log chat program messages as - LOG_NORMAL, not LOG_ERROR. - -Fri Feb 14 00:17:57 1992 Ian Lance Taylor (ian@airs.com) - - * uucico.c (ucatch), uuxqt.c (uqcatch): Neils Baggesen: under - HAVE_BNU_LOGGING, don't lose the system name when dieing. - - * uulog.c, Makefile, MANIFEST: wrote uulog. - - * uuname.c, Makefile, MANIFEST: wrote uuname. - - * bnu.c (ubadd_perm_alternate): T. William Wells: must xstrdup the - system name before calling uadd_validate. - - * log.c (ulog_close): Micheal Nolan: don't refer to eLdebug if the - DEBUG configuration parameter is 0. - - * uucp.c (main): Niels Baggesen: abtname must be copied into - memory, or it will be overwritten by the next file to be copied. - -Sun Feb 9 00:12:58 1992 Ian Lance Taylor (ian@airs.com) - - * uucico.c (fuucp), prot.c (fsend_file, freceive_file): Bob Denny: - call fmail_transfer before calling fsysdep_did_work, because the - latter frees up strings used by the former. - - * sysh.unx, sys1.unx (mkdir), uudir.c (new file), Makefile: added - HAVE_MKDIR configuration parameter for systems without the mkdir - system call. The emulation function in sys1.unx invokes the new - suid program uudir which sets its uid to uucp and invokes - /bin/mkdir. Added rules to create uudir to Makefile. - -Sat Feb 8 14:25:50 1992 Ian Lance Taylor (ian@airs.com) - - * sysh.unx, sys1.unx (opendir, readdir, closedir), sys4.unx, - sys5.unx: added HAVE_OLD_DIRECTORIES configuration parameter to - support systems without opendir/readdir/closedir which use - original Unix directory format. - - * sysh.unx, sys1.unx (dup2): added HAVE_DUP2 configuration - parameter and dup2 emulation function. - - * sys1.unx (zsysdep_local_name): put utsname structure on stack - rather than making it static. - - * sysh.unx, sys1.unx (usysdep_initialize, getcwd): if we have - neither getcwd nor getwd, fork /bin/pwd to get the current working - directory. - - * system.h, uucico.c (main), uuxqt.c (main), uux.c (main), uucp.c - (main), uuchk.c (main), sys1.unx (usysdep_initialize), sys6.unx - (fsysdep_needs_cwd, zsysdep_add_cwd): because getting the current - working directory can be expensive on Unix, since some - implementation of getcwd fork a shell to execute pwd, only try to - get the cwd if it is going to be needed by uux or uucp. - - * uucico.c (main), uuxqt.c (main), uux.c (main), uucp.c (main), - uuchk.c (main), log.c (ulog): handle all possible signals raised - by abort, namely SIGABRT, SIGILL and SIGIOT. In ulog always call - abort rather than raise (SIGABRT). - - * sys4.unx (usysdep_get_work_free): the qSwork_file information - was freed up incorrectly if a file transfer failed. - - * sysh.unx, sys2.unx: Archaic Zilog System III computers use - setret and longret rather than setjmp and longjmp, so I added a - HAVE_SETRET configuration option. - - * prott.c (ftstart, ftsenddata): shifts of integers by more than - 15 are not portable. - - * prot.c (fsend_file, freceive_file, fploop, fgot_data): I ran - into an old compiler which couldn't handle the calls to pffile, so - I simplified them to use a variable. - - * port.c (fmodem_dial): cast result of alloca. - - * getopt.h, getopt.c: Jay Vassos-Libove: renamed getopt and - related variables by macro defining them to gnu_*. This avoids - conflicts with system header files and system libraries. - -Fri Feb 7 12:08:42 1992 Ian Lance Taylor (ian@airs.com) - - * everything: added HAVE_STRING_H and HAVE_STRINGS_H. Removed - include of <string.h> in every source file and put it in uucp.h. - Since I had to change everything anyhow, added 1992 to the - copyright date. - - * uucico.c (fcall): Bob Denny: retry time not reached is not - really an error, so just make a normal log entry for it. - -Sun Feb 2 01:38:47 1992 Ian Lance Taylor (ian@airs.com) - - * uucp.c (main): Get the file name for the destination of a local - copy using zsysdep_real_file_name rather than zsysdep_in_dir, - since the latter doesn't get the basename of the argument. - - * sys3.unx (fsysdep_get_status): Niels Baggesen: cast enum to int - before comparison. - - * system.h, uucp.c (main), uux.c (main), sys6.unx (fsysdep_access, - fsysdep_daemon_access): Niels Baggesen: check user access to file - since programs are running setuid.

This will let the NeXT - define it in some header file. - - * sysh.unx, sys2.unx, sys5.unx, tstuu.c: Mike Park: handle - HAVE_UNION_WAIT completely.

It provides -everything you need to make a UUCP connection. It includes versions -of uucico, uusched, uuxqt, uux, uucp, uustat, uulog, uuname, uuto, -uupick, and cu, as well as uuchk (a program to check configuration -files), uuconv (a program to convert from one type of configuration -file to another) and tstuu (a test harness for the package). - -This is the standard UUCP package of the Free Software Foundation. - -The package currently supports the 'f', 'g' (in all window and packet -sizes), 'G', 't' and 'e' protocols, as well a Zmodem protocol, the FX -UUCICO 'y' protocol, and two new bidirectional protocols. If you have -a Berkeley sockets library, it can make TCP connections. If you have -TLI libraries, it can make TLI connections. It supports a new -configuration file mechanism which I like (but other people dislike). - -The package has a few advantages over regular UUCP: - - You get the source code. - - It uses significantly less CPU time than many UUCP packages. - - You can specify a chat script to run when a system calls in, - allowing adjustment of modem parameters on a per system basis. - - You can specify failure strings for chat scripts, allowing the - chat script to fail immediately if the modem returns ``BUSY''. - - If you are talking to another instance of the package, you can use - the new bidirectional protocol for rapid data transfer in both - directions at once. You can also restrict file transfers by size - based on the time of day and who placed the call. - -On the other hand: - - It only runs on Unix. The code is carefully divided into system - dependent and system independent portions, so it should be - possible to port it to other systems. It would not be trivial. - - You don't get uuclean, uusend, uuq, uusnap, uumonitor, uutry, - uupoll, etc. If you have current copies of these programs, you - may be able to use them. Shell scripts versions of uuclean and - uutry are provided, with most, if not all, of the functionality of - the usual programs. I believe the supplied uustat program allows - you to do everything that uuq, uusnap and uumonitor do. uupoll - could be written as a shell script. - - The package does not read modemcap or acucap files, although you - can use V2 configuration files with a BNU Dialers file or a dialer - file written in my new configuration file format. - - The package cannot use SCO dialer programs directly, although it - can with a simple shell script interface. - -If you start using this package, I suggest that you join the mailing -list (see above) to keep up to date on patches and new versions. I am -also open to suggestions for improvements and modifications. - -DOCUMENTATION - -The documentation is in the file uucp.texi, which is a Texinfo file. -Texinfo is a format used by the Free Software Foundation. You can -print the documentation using TeX in combination with the file -texinfo.tex. DVI, PostScript and info versions of the documentation -are available in a separate package, uucp-doc-1.06.tar.gz. - -See the TODO file for things which should be done. Please feel free -to do them, although you may want to check with me first. Send me -suggestions for new things to do. - -The compilation instructions are in uucp.texi. Here is a summary. - - Edit Makefile.in to set installation directories. - - Type ``sh configure''. You can pass a number of arguments in the - environment (using bash or sh, enter something like ``CC=gcc - configure''; using csh, enter something like ``setenv CC gcc; sh - configure''): - CC: C compiler to use; default is gcc if it exists, else cc - CFLAGS: Flags to pass to $CC when compiling; default -g - LDFLAGS: Flags to pass to $CC when only linking; default none - LIBS: Library arguments to pass to $CC; default none - INSTALL: Install program; default install -c or cp - The configure script will compile a number of test programs to see - what is available on your system, so if your system is at all - unusual you will need to pass in $CC and $LIBS correctly. - - The configure script will create config.h from config.h.in and - Makefile from Makefile.in. It will also create config.status, - which is a shell script which actually creates the files. Please - report any configuration problems, so that they can be fixed in - later versions. - - Igor V. Semenyuk provided this (lightly edited) note about ISC - Unix 3.0. The configure script will default to passing -posix to - gcc. However, using -posix changes the environment to POSIX, and - on ISC 3.0, at least, the default for POSIX_NO_TRUNC is 1. This - means nothing for uucp, but can lead to a problem when uuxqt - executes rmail. IDA sendmail has dbm configuration files named - mailertable.{dir,pag}. Notice these names are 15 characters long. - When uuxqt compiled with -posix executes rmail, which in turn - executes sendmail, the later is run under POSIX environment too! - This leads to sendmail bombing out with 'error opening 'M' - database: name too long' (mailertable.dir). It's rather obscure - behaviour, and it took me a day to find out the cause. I don't - use -posix, instead I run gcc with -D_POSIX_SOURCE, and add - -lcposix to LIBS. - - On some versions of BSDI there is a bug in the shell which causes - the default value for CFLAGS to be set incorrectly. If ``echo - ${CFLAGS--g}'' echoes ``g'' rather than ``-g'', then you must set - CFLAGS in the environment before running configure. There is a - patch available from BSDI for this bug. (Reported by David - Vrona). - - On AIX 3.2.5, and possibly other versions, cc -E does not work, - reporting ``Option NOROCONST is not valid.'' Test this before - running configure by doing something like - touch /tmp/foo.c - cc -E /tmp/foo.c - This may give a warning about the file being empty, but it should - not give the ``Option NOROCONST'' warning. The workaround is to - remove the ",noroconst" entry from the "options" clause in the - "cc" stanza in /etc/xlc.cfg. (Reported by Chris Lewis). - - Examine config.h and Makefile to make sure they're right. - - Edit policy.h for your local system. - - Type ``make''. - - Use ``uuchk'' to check configuration files. You can use - ``uuconv'' to convert between configuration file formats. - - Type ``make install'' to install. Note that by default the - programs are compiled with debugging information, and they are not - stripped when they are installed. Read the man page for strip for - more information. - - On older System V based systems which do not have the setreuid - system call, problems may arise if ordinary users can start an - execution of uuxqt, perhaps indirectly via uucp or uux. UUCP jobs - may wind up executing with a real user ID of the user who invoked - uuxqt, which can cause problems if the UUCP job checks the real - user ID for security purposes. On such systems, it is safest to - put ``run-uuxqt never'' in the `config' file, so that uucico never - starts uuxqt, and invoke uuxqt directly from cron. diff --git a/gnu/libexec/uucp/TODO b/gnu/libexec/uucp/TODO deleted file mode 100644 index f1bed5f..0000000 --- a/gnu/libexec/uucp/TODO +++ /dev/null @@ -1,777 +0,0 @@ -This is a list of things to do for the Taylor UUCP package.

William Wells: close and open the Debug file after each file -transfer. Alternatively, cycle through a series of Debug file names -every 1000 lines or so. - -106. - -Marty Shannon: add a time command for ports, to specify when they may -be used. - -115. - -T. William Wells: new options for uustat: - -i display job ids only -Also, there should perhaps be a configuration option to request uustat -to only display jobs submitted by the user running uustat, except for -root and uucp. - -117. - -Marc Unangst: provide some way to change the debugging level of a -running uucico. T. William Wells suggests having it read a file to -change arbitrary configuration information, although obviously one has -to be careful of what gets changed while a connection is active. - -120. - -Jarmo Raiha: new chat-fail commands: one to not update the status file -and require a retry wait, and one to permit the string to occur a few -times before reporting an error. - -124. - -Peter da Silva: perhaps there should be a ``chat-end-program'' command -to let a program be run after the initial handshake has been completed -and the protocol has been selected and turned on. This would let -people run stty to change their terminal parameters. - -128. - -Richard Stallman: have an interactive program to set up a chat script. -It would let you type directly to the port, recording what you type as -send strings and recording what comes back from the other side as -expect strings. - -129. - -Use POSIX fcntl locks when possible instead of creating a lock file. - -138. - -T. William Wells: BNU apparently uses a file named A.whatever to hold -the line number reached in current C. file processing. This is a -hack, and won't work right with size control anyhow, but -fsysdep_did_work could, for example, clobber the first byte in the -line to a # or something to mark that it had been finished. Still a -hack, but a better one. - -139. - -Patrick Smith: incorporate patches to generate full debugging traces -with less debugging file overhead. The debugging file repeats too -much information at great length right now--not good. - -141. - -Franc,ois Pinard: batch up pauses and delays in chat scripts and do -them all at once in a single system call. This is particularly useful -for pauses on systems which don't support subsecond sleeps. For -everything else it's a fairly minor optimization. - -142. - -Franc,ois Pinard: give uustat an option to requeue jobs to another -system. This only makes a lot of sense for rmail executions, but it's -fairly easy to do for any type of command. I think uucico does all -the file checking needed to ensure that this doesn't break security, -but that should be double-checked. - -144. - -T. William Wells: add a -g option to uucico to permit specifying the -maximum grade to be transferred at that time. This could restrict the -timegrade command further, but should not be permitted to override it. - -145. - -T. William Wells: if uucico or uuxqt get started with bad arguments, -put an indication in the log file since stderr may be /dev/null. - -146. - -Richard Todd: it would be nice to sometimes be able to request the -other side to turn on debugging. - -147. - -Bart Schaefer: some more possible options for uucico: - -R reverse roles (hangup immediately). Not too exciting. - some method to restrict calling to particular systems. - -148. - -Jarmo Raiha: some method to control the work queue at the remote end. -This could get awfully general, though. - -149. - -The interaction of the time command and defaults can be confusing, -since any time command in the actual system entry, even a fairly -specific one, will wipe out the default entry. Not sure what can be -done about this. - -150. - -Jarmo Raiha: should there be some way to specify modem initialization -strings when uucico is hanging on a port with -l or -e? This would -presumably require a new type of chat script associated with a dialer. - -151. - -Petri Helenius: log complete CONNECT string reported by modem, so that -the baud rate is recorded in the log file. - -152. - -Marc Evans: let the protocol selection be based on the CONNECT string, -so that different protocols could be selected based on what type of -connection was made. - -153. - -Chris Lewis: provide a signal to get a core dump even on systems which -won't do core dumps if the uid is not the euid. One could catch a -signal, call setuid (getuid ()), and then raise the signal again. -Unfortunately the core dump has to wind up in a directory which is -world writable, so that the process is able to create the core file, -but is not world readable, since that would permit anybody to read the -core dump file and extract private information from it. - -154. - -Les Mikesell: write a new version of dial.o, with provisions for -running a chat script. - -155. - -Scott Blachowicz: perhaps there should be some way to telling uucico -to not log certain errors. This could get fairly complex, though. - -156. - -Franc,ois Pinard: have uustat -m report the time of the last -successful conversation when reporting a failure. - -158. - -Thomas Fischer: should there be a way to completely disable an entry -in the sys, port or dial file? Such as a ``disable'' command? - -159. - -Petri Helenius: when uuxqt -s is invoked, lock uuxqt for the system so -that only one uuxqt is invoked per system. If the -c option is used, -don't lock on a per system basis, and ignore any per system locks -(regardless of -s). If neither option is used, respect existing -system and command locks, and do any other type of file. - -161. - -Scott Blachowicz: provide some sort of include mechanism for the -configuration files. - -164. - -Ed Carp: preserve files if uuxqt execution fails. - -165. - -Marc Sheldon: use exit codes from <sysexits.h> in uux and uucp. - -166. - -Chip Salzenberg: allow chat failure strings to specify a retry time. - -168. - -Jose A. Manas: allow a maximum connect time, after which we try to -hang up the connection. This requires a protocol extension, since -there's no way to force the other side to hang up. The best we can do -without an extension is refuse to send any new jobs ourselves. Of -course, we could just drop the connection. - -169. - -Franc,ois Pinard: when given uustat -k00FC, check each possible job ID -and use it if there is an unambiguous one. - -170. - -T. William Wells: if ! HAVE_SETREUID && ! HAVE_SAVED_SETUID, fork a -subprocesses to revoke setuid and read the file over a pipe. - -171. - -Provide some option to have the internal uuconf functions not start -with an underscore. - -172. - -T. William Wells: have some way to configure the parity for cu. - -173. - -Gert Doering: uuchk should display unknown system information. - -175. - -T. William Wells: -Cu will not let itself be interrupted before the connection is -established. If the chat script doesn't write something, cu does -something odd, I've forgotten exactly what. Cu takes an -inordinate amount of time after the line drops to exit. Somebody, -cu, I think, but maybe uucico, drops dtr twice sometimes. Again, -somebody will attempt to write after a hangup signal has been -received. Once a hangup has been received, I/O should not be -attempted. Among other things this will save the bacon of those -who have brain damaged serial drivers (FAS, sigh, is among them) -that don't handle output properly on a dropped line. - -Me: -Note that sometimes you do want to write to a line after receiving a -hangup signal. For example, you might want to use ATZ to reset a -modem. - -176. - -Hans-Dieter Doll: provide some way (another escape sequence) to pass -the protocol to a chat-program. Or, allow the protocol as an argument -to the chat script command, which is more general, but maybe a bit too -fancy. - -177. - -Nickolay Saukh: use a default port for cu, you can just do ``cu -number''. - -180. - -Nickolay Saukh: if we have received a partial file, request the remote -system to start sending from that point. We currently accept SVR4 -style remote file positioning requests, but we do not generate them. - -181. - -Mark Powell: provide some way to restrict file transfer by size as -well as grade? One way would be to let uux select the grade based on -the file size. - -182. - -Mark Powell: permit using multiple timetables in a single time -statement. - -183. - -Optionally check for interrupts in fcopy_file, since it can take a -long time to copy a file named in a uucp request. - -185. - -A syntax error in a command received from the remote system should not -hold up the queue. Unfortunately, I don't know what can be done -except deny the command and report it. Reporting a garbled command -error should report the command correctly, rather than just the first -character. - -186. - -Franc,ois Pinard: have an option to control nostop vs. stop on the cu -command line. - -187. - -Fix the notion of %nostop to be SVID compatible. - -188. - -Frank Conrad: provide a means to set the strip mode for a port, to -make it easy to use it from cu. - -189. - -Marc Unangst: there should be a way to specify that a system should -only be called if there are jobs of a certain grade, but if the system -is called then jobs of any grade should be transferred. This -basically means splitting the ``timegrade'' command into two commands: -``place-call-timegrade'' and ``transfer-timegrade''. Or maybe another -optional argument to ``timegrade'': - timegrade grade time-string [retry] [transfer-any] -not to mention - time time-string [retry] [transfer-any] -Or maybe a separate command for a system or port like - transfer-any BOOL - -190. - -Chip Salzenberg: it would be really nice if uucico could automatically -figure out when it could use an E command, so that uux didn't have to -generate it and so that uucico could use with other versions of uux. -Unfortunately, it would require uucico to read the execution file to -see if it were suitable; this would be complex, but it would probably -be worth it since normally the execution file would wind up not being -sent. Of course, the current method works too; it's just harder to -combine with other versions of UUCP. - -191. - -Brian J. Murrell: should there be a way to cu a specific alternate? - -192. - -Andrew A. Chernov: Perhaps cu -pport system should be able to try -different alternates for the system, because there might be different -phone numbers to try. - -193. - -Brian J. Murrell: it would be nice to be able to ^C a cu chat script -if you know it's going to fail. Right now you have to use ^\. - -194. - -Steven S. Dick: have some way to force uucico off the phone at a -certain time. If that is done, it might be cool to have some way to -predict how long a file transfer will take, and not do it if it will -take too long. But, if doing file restart, you can just quit and then -pick it up later. - -195. - -Franc,ois Pinard: if the disk fills up, or some other error occurs, -while receiving a file, perhaps it would make sense to turn the -connection around immediately and see if the other side had anything -to do, and then try again later. This would require a protocol -extension. I don't know if it's worth it. The code should be checked -to see how well it handles a disk full situation. - -197. - -Try alternate IP addresses if there are any. - -198. - -Lele Gaifax: mention the device in Stats, and provide some way to -associate the entry in Log with the entry in Stats. - -199. - -Michael Richardson: provide some way to turn on parity for the login -chat, since some systems apparently require it. Provide some way for -cu to control parity after connecting. - -200. - -Chip Salzenberg: add max-remote-debug to config. - -201. - -Gert Doering: change the timeout message in chat scripts to reflect -which chat script timed out (dialer or login). - -202. - -Bill Foote: have uuchk check whether a system is defined more than -once. - -203. - -Eric Ziegast: allow specification of the minimum grade to receive, as -well as the maximum grade. Probably sending a second character after -the -pM argument would work fine. - -204. - -Tom Rushworth: perhaps there should be some program which can be used -to retrieve the current spool directory. Perhaps on option on uustat. - -207. - -James B. O'Connor: use additional messages in the status file when -placing a call, such as Dialing, Chatting, and the like. Slightly -less efficient. - -208. - -When checking whether a file may be received into a directory, perhaps -uucico should check using the real user ID rather than insisting that -the directory be world writable. This should be a policy.h parameter. -This would enable sites which use different uids for each incoming -UUCP login to have better control over security. - -209. - -Jon Vos: add an alias command for ports. - -210. - -Joe Wells: I'd like to have a way so that if the dial chat fails due -to "NO CARRIER", in addition to this log message: - - ERROR: Chat script failed: Got "NO\sCARRIER" - -I would get another log message right next to it that would look like -this: - - ERROR: Chat script failed: 5 "RRING" strings seen - -Ian: I doubt this is worth implementing in uucico, but it might make -sense for an external, or otherwise more independent and controllable, -chat program. - -211. - -Joe Wells: In some cases it would be nice to be able to change the set -of chat-fail strings in the middle of the chat script. Personally, I -think this is too complex for the simple chat scripts currently -implemented. - -212. - -Joe Wells: There should be an option to all programs directing them to -send all debugging output to the log file. This would just involve -calling ulog_to_file at some point just after reporting any usage -messages. - -213. - -Joe Wells: There should be a way to specify the execution directory -used by uuxqt. This would avoid certain sorts of permissions -problems. Some mechanism would still be needed for using multiple -directories. - -214. - -Joe Wells: uuto should be documented. - -215. - -Joe Wells: Perhaps it should be possible to use multiple spool -directories. It would be a lot of work, though. - -216. - -Joe Wells: It should be possible to specify only one of complete or -abort. - -217. - -Dan Everhart: It would be nice if the chat-fail string could affect -the error message reported by uustat, so that uustat could say -something ``Line was busy''. - -218. - -Andrew A. Chernov: Add a chat-char-delay xx configuration parameter, -which has the effect of adding \p after each character, with delay xx. -This is to accommodate modems which can't accept command characters at -a given baud rate. - -219. - -Gert Doering: Provide some mechanism for specifying the maximum length -of a call. Convenient for anonymous UUCP sites. - -220. - -Joe Wells: There should be some way for "cu" to obey user commands -during the dial chat. Right now, the only thing the user can do is -send signals (e.g. type Control-C). This leads to user complaints -that "cu" is not obeying its documentation. - -221. - -Joe Wells: Right now, if there is any failure in the dial or login -chat scripts, the remote system alternate is skipped even though the -cause of the failure may have been the local serial port or modem. -"uucico" will not try another modem with the same remote system -alternate. If the remote system only has one alternate, then it is -skipped entirely. - -Thus, there should be a way to specify that when certain expect -strings are not seen or certain chat-fail strings are seen that the -port is skipped instead of the remote system alternate. - -222. - -Richard H. Gumpertz: Support pipelines in uuxqt. Right now they are -only supported if uux puts in an 'e' line (which it does) and shell -executions are permitted (which they normally are not). It would be -possible to permit restricted pipelines by handling the pipe character -specially and making sure all commands in the pipeline were permitted. - -223. - -Bill Sommerfeld: When dialing out, set the status to DIALING rather -than CONNECTION CLOSED. Setting the status takes a bit of time; it's -hard to tell where the right break-even point is. - -224. - -Joe Wells: Keep track of the last successful incoming call separately -from the last successful outgoing call. Currently the two times are -both put together in the status file. - -225. - -Joe Wells: It would be nice if uustat would provide a way to avoid -bouncing mail that it sent itself, to avoid sending notification -e-mail for notification e-mail. I can't think of a mechanism, though -(using a special grade for uustat does not work because most mail -programs do not provide a mechanism for passing a grade through to -uux). - -226. - -Joe Wells: It would be nice if uustat could know whether it had sent -mail for a particular job, to avoid generating multiple messages for -the job. - -227. - -Joe Wells: It would be nice if dialcode suffixes were supported, as -well as prefixes. - -228. - -Joe Wells: It would be nice to support another spool directory scheme -which split stuff up more to avoid very large directories. This would -be most useful for the files which are named in C. and X. files, -rather than for the C. and X. files themselves (since C. and X. files -are rarely looked up by name). Basically, some sort of partition of -the D. directory is called for. - -229. - -Joe Wells: ``It would be nice if the exit sequence of "cu", where it -runs the complete chat script and then disconnects could be aborted -without disconnecting. (Yes, I know, this is a strange desire.) It -would be nice to be able to reinvoke the dial chat by user command in -"cu". It would be nice to be able to invoke an arbitrary named chat -script in "cu".'' - -230. - -Kevin Johnson: Provide some mechanism such that all requests to a -particular system were automatically forwarded through some other -system. This would be useful to hide details of a non-strongly- -connected network, particularly if the details were subject to change. - -231. - -Gert Doering: Perhaps it should be possible to -r the default for uucp -and uux. This would require adding a new option to force the -invocation of uucico. - -232. - -Mark Davies: spaces are not handled correctly in the -a argument of -uux. If an E command is generated, the requestor address is not -quoted correctly, nor is it parsed correctly. If an execution file is -generated, the R line is not parsed correctly. - -233. - -Emmanuel Mogenet: provide some mechanism for a maximum number of -garbage bytes during a chat script before giving up. - -234. - -Scott Ballantyne: The address for a TCP port should be separate from -the phone number, so that a TCP dialer can use \D. - -235. - -Peter Wemm: The 'i' protocol default parameters do not work at 2400 -baud, because the time it takes to transfer half the packets is less -than the timeout time. Of course people can always change the -parameters, but it would be nice if this were dealt with somehow. - -236. - -Andrew A. Chernov: Perhaps uuxqt should log when it terminates. - -237. - -dialer-sequence doesn't really do the right thing. There is no way to -specify both the TCP address and a phone number. - -238. - -cu -t doesn't work at all. It does nothing. - -239. - -Paul Pryor: Perhaps a service command should be added to the sys and -port files. This command would be used as ``service cu'' to indicate -that the system or port was only available to cu, not to UUCP. - -240. - -Tim Iverson: The 'g' and 'i' protocol code tends to parse data packet -headers twice. It processes them once to find out how large the -packet is, waits for that data to arrive, and then processes the -header again the second time around. It would be possible to avoid -this by changing the code to be a simple state machine which -remembered where it was in the process of parsing the packet. - -241. - -Klaus Dahlenburg: Log a more precise reason for failure in the .Status -file: e.g., all ports in use, no matching ports, etc. - -242. - -Steven S. Dick: It would be helpful if there was a way to get uuchk to -dump the data from ports/dialers/etc that was NOT picked up from the -sys file. In other words, add some option to scan the port file and -the dial file, presumably using uuconf_find_port for the former and -uuconf_dialer_names for the latter. - -243. - -Kai Michael Kretschmann: Add a configure option to drop the connection -if jobs are coming in too slowly, indicating a bad connection. diff --git a/gnu/libexec/uucp/VERSION b/gnu/libexec/uucp/VERSION deleted file mode 100644 index 6e1a45b..0000000 --- a/gnu/libexec/uucp/VERSION +++ /dev/null @@ -1,4 +0,0 @@ -Version 1.06.1 - -a complete, unmodified version of this program is available from -prep.ai.mit.edu. diff --git a/gnu/libexec/uucp/common_sources/trans.h b/gnu/libexec/uucp/common_sources/trans.h deleted file mode 100644 index d057ab2..0000000 --- a/gnu/libexec/uucp/common_sources/trans.h +++ /dev/null @@ -1,288 +0,0 @@ -/* trans.h - Header file for file and command transfer routines. - - Copyright (C) 1992, 1993, 1994 Ian Lance Taylor - - This file is part of the Taylor UUCP package. - - This program is free software; you can redistribute it and/or - modify it under the terms of the GNU General Public License as - published by the Free Software Foundation; either version 2 of the - License, or (at your option) any later version. - - This program is distributed in the hope that it will be useful, but - WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This environment consists of a 486, a 386, -Xand a 386SL laptop, all of which run Taylor uucp under Linux. The 386 -Xlaptop gets used a lot, since it goes wherever I go and I answer a lot -Xof news and email every day. Often, I must use other people's facilities -X(phone lines and such) to send out replies and post news if I'm not at home. -XSince it's not fair to the client for them to pay for my zone calls back -Xto my home in Fremont, I place the calls on my phone card. Unfortunately, -XPacBell is very proud of the services they offer, especially in regards -Xto this convenience of automatically charging calls to my house wherever I -Xmay be. Considering that this can be very expensive to do, I searched for -Xa way to cut my phone bill down to something I could afford to pay each -Xmonth without fainting every time I saw the bill. -X -XThe first thing I did was to go out and plunk $195 for a 14.4KB modem. -XThat helped, but C-News is very slow on my laptop, and batching articles -Xis even slower, and email (of course) isn't batched at all. Even with -XMNP5 compression turned on, this doesn't make for a very efficient setup, -Xeven at high speeds. -X -XPlaying around with uucp told me that the line turnaround wasn't that much -Xoverhead, nor was sending the C./X. files (the execute files) - the real -Xoverhead was sending out uncompressed news and especially email, since -XI subscribe to several mailing lists and digests can run quite large. -X -XI looked at uubatch, but the most current version I could find (1.05) was -Xnot compatible with Taylor uucp (and I had no other alternative), so I -Xdecided to write my own. Experiments with "gzip -9" convinced me that -Xthat was the way to go, since gzip gives email and news 60 to 75 percent -Xcompression, which would tend to cut one's phone bill significantly. -X -XYou hold in your mailbox (or news reader) the end result of that effort. -XBear in mind that (1) this is a "first cut" and while it is unlikely that -Xthere are very many bugs, there are certainly places where the programs could -Xbe improved and tuned. Suggestions and comments are welcome! -X -XTo install: -X -X 1. Feed this to shar. -X 2. Look at the Makefile. Make sure that the paths for -X things are set up correctly. -X 3. Look at uucomp.h and make sure that the path and -X options for COMPRESS/UNCOMPRESS are set up properly. -X 3. Type "make". This will make uucomp, crmail, and crnews -X and will place them in /usr/bin. Move Compress into -X /usr/lib/uucp. -X 4. Make an entry in crontab to do -X /usr/lib/uucp/Compress site1 site2 site3... -X occasionally. It is suggested that this be done fairly -X frequently. Alternately, you could set up a login shell -X for selected sites to run uucomp every time that site -X logged in. -X 5. Don't forget to add /usr/bin/crmail and /usr/bin/crnews -X to the list of programs allowed to be executed in your -X Permissions file (if running HDB UUCP), or whatever is -X appropriate for your version of uucp. -X -XEnjoy! Any questions or comments can be sent to erc@apple.com. -X -XNote: This is tuned for Taylor uucp, but would not be particularly -Xdifficult to adapt to other version of uucp.

That uupoll checked any site name against -the "hardwired" L.sys and did end with a "Bus error" if the site could not -be found. There was no source available to modify so it had to be created -from scratch. -The program autopoll has no equivalent an the NeXT. The intentions behind -it was to automate the task of rescheduling any failed call. It may be -started by an entry in the crontab tables in just the same way uucico is -started (it will start uucico): -X -05 5 * * * uucp /usr/local/lib/uucp/autopoll -r1 >>/tmp/poll.log 2>&1 -X -Any messages go to stderr or a file (if compiled with that option); in case -the file could not be opened it will use stdout to tell you just that and quit. -To catch any output one may place the string -X -X >>/tmp/poll.log 2>&1 -X -into the command line as well. Uupoll as well as autopoll will place only -a start message into the logfiles in case they are invoked manually from -the shell. -If the call fails autopoll will reschedule uucico for a later time by means -of an AT job. -The messages given by uupoll and autopoll carry an indicator to inform about -the nature of an error; they are: -X -- (I) informal message; such as ".. started" ".. ended". -- (W) there might be an error but the program decided to go ahead. -X The exit code will be at least 4. -- (E) a severe error was encountered that either aborts the whole run or -X only the task for one site will be aborted. -X The exit code will be at least 8. -- (C) a catastrophic error has been found such as unable to fork. The run -X is aborted. -X The exit code will be at least 16. -The final message will show the exit code the programm has terminated with. -X -For more information see the man pages or look into the source. -X -INSTALLATION: -all files should be placed in one folder. Then examine and change the files -Makefile and conf.h to meet your needs. To compile uupoll some files of -uucp must be available (see Makefile: uucpsrcs) -If not already there change to the directory which contain the files and type: -X -make -X -this should compile UUPOLL and AUTOPOLL. There should only be a warning -that rcsid is defined but not used. -Before actually installing you should test the programs to be working as -desired. -Then check the Makefile for the final placement of the modules and the man -pages. Make sure the ownership and setuid is what you need on your machine -to run the program(s). -Then su to root and type: -X -make install -X -which should install the above programs and the man pages in the appropriate -directories. -Some word on the coding: have mercy!

This -is typically done by entries in the -.IR crontab -table(s) which will invoke -.IR uucico. -.IR uucico -can also be invoked by -.IR uupoll (8C). -All methods have in common that there is no automatic retry by -.IR uucico -itself in case the call failed for some reason. -Either manual -intervention or some sort of scripts must be used to overcome this -limitation. -.PP -.IR Autopoll -can be used to automate up to a certain degree the task of rescheduling -a call. None of the standard programs already mentioned need to be -modified to get this working. Also not recommended (see BUGS section) -.IR uucico -may be an alias to -.IR autopoll -as all arguments passed to -.IR autopoll -will be copied verbatim to -.IR uucico. -In case this is done by link or other means the original -.I uucio -must still be available in a directory outside of the normal search path -otherwise -.I autopoll -can't do what it's intended to do and will form a loop. -.PP -When -.IR autopoll -is called thre will be a check on the \-s, \-S and \-f option to -see whether this -is a specific call or not. Also the \-S and the \-f option must be checked -to determine the type of call: honor any imposed wait for a site or not. -Any call to ourself or to an unknown site will be refused. The known sites -will be obtained by a call to -.IR uuname(1). -All other options will not be checked in any way. Next to this -.IR uucico -is called and the exit code is checked for a `1' which indicates that the call -failed for some reason whatsoever. A `0' exit code will be interpreted as -a success and -.IR autopoll -ends immediate. If the call seems to be unsuccessful a new call is scheduled -for any site whose .Status files have a retry period greater than 0. The -retry will be scheduled by means of placing an -.IR at -job at the time of the failing call plus any wait time given. For those -sites that have been called with either the \-f or \-S option the retry -time will be the time of the failing call plus 120 seconds. -.PP -In case the time calculated from the values found in a \.Status file is -lower than the current time, the current time plus 60 seconds will be taken -as the retry time. -.PP -A site will -.IR not -be automatically called again if one of the following -conditions is met: -.PP -\- -.IR uucico -is terminated by a signal -.PP -\- either fork() or exec() failed -.PP -\- the -.IR at -command failed for any reasons. -.PP -\- if no wait should be honored and the retry time is found to be zero. -(this may indicate a `Wrong time to call' condition. -.PP -There are other circumstances that may lead to not reschedule a call or -not to call -.IR uucico -at all, all of which should be accompanied by (a) self explanatory message(s). -.SH BUGS -\- invalid options will make -.IR uucico -fail. The exit code for this type is the same as for any other failure; this -can reschedule the call over and over again or never. -.PP -\- -.IR autopoll -may not work as expected when called with options other than \-r1, \-s, -\-S or \-f. -.PP -\- a rescheduled call may fail with `wrong time to call' the second time -but will be rescheduled again. The times to call won't be checked by -.IR autopoll -and the .Status file may not indicate this in case the \-c option is given. -.PP -\- in case the ..._DIR points to an invalid file a `Bus error' my pop up -during the `exec' call. -.PP -\- the `chat-timeout' value may have to be increased when using -.IR autopoll. -An indication to do that is that the call fails short after `CONNECT' -has been received with `Time out in chat script'. -.PP -\- the site names given will be checked aginst the output of -.I uuname -without any alias expansion done. -.PP -\- the text strings whithin the \.Status files will not be used to detect -a failing call. -.SH FILES -.nf -/usr/local/lib/uucp UUCP internal utilities -/usr/lib/uucp -/usr/local/bin UUCP internal utilities -/usr/bin -/usr/spool/uucp/.Status/ Status files for each site -/usr/spool/uucp/ UUCP spool area. one of its sub- -X directories will hold the null jobs. -/tmp/poll.log This file is present only if autopoll -X has been compiled to place the messages -X into a file.

The original version (up to 3.1) had a -X bug in that -X an unknown site given as argument would yield in a `Bus error' condition. -Using any other type of UUCP like Taylor-UUCP with the option of having -a different file structure as well as a different L.sys will therefore -make it necessary to do maintenance to the (unused) L.sys as well to keep -.IR uupoll -going. This one has been programmed from scratch due to the fact that no -source code was available. Some enhancements have been incorporated into -this version: -.PP -\- the default grade may now be compiled different from `A'. -.PP -\- the options may now be given in any order and the \-g option may be given -more than once. Any option will be used immediately when encountered and -will stay in effect unless reset; this does not apply to the \-x and \-n -option which can't be reset. The processing of options is guaranteed to be -from left to right so that some grouping may be achieved (see below). -.PP -\- -.IR uupoll -may be used to call any program instead of -.IR uucico -namely -.IR autopoll -to ease the task of rescheduling a failed call. -.SH DESCRIPTION -.I Uupoll -is used to force a poll of a remote system. It queues a null job for the -remote system, unless the \-x option has been given, and then invokes -either -.IR uucico (8C) -or -.IR autopoll (8C) -or any other program depending on how -.IR uupoll -is customized. If used in conjunction with -.IR autopoll -the latter will then invoke -.IR uucico. -.SH OPTIONS -The following options are available: -.TP 8 -.BI \-g grade -Only send jobs of grade -.I grade -or higher on this call. The -.I grade -stays in effect until it is changed by a different \-g option. -.TP 8 -.B \-n -Queue the null job, but do not invoke the program that actually calls -the named site(s). -The \-n option once given will apply to all sites following to the -.IR right -of it. -.TP 8 -.B \-x -Do not place a null job for all following sites. This option must be given -before the \-n option. The \-n option will nullify this. Any grade in effect -will not be honored because -.I uucico (Taylor) -does not carry the \-g option at the moment. -.PP -.I Uupoll -is usually run by -.IR cron (5) -or by a user who wants to hurry a job along.

These -sites will be called at the next regular schedule. -.SH BUGS -When more than one site is given on the command line and no \-n option is -given there will be an immediate invocation of -.IR uucico -or -.IR autopoll -for -.IR all -sites given.

The lack of source made it impossible -X to modify the supplied uupoll. -X -X Call: uupoll [-n] [-x] [-g[A | 0-9,A-Z,a-z]] site ... -X -X -n just place a poll file but do not call uucico; -X This option can be given only once. -X -x meaningful only for sites not affected by the -n -X option. It prevents the creation of a poll file; -X the default is to place one. In case the poll fails -X there will be no attempt to poll those sites on -X the next general (unspecific) poll. If using -X autopoll the site will be called at the next + 1 -X run of autopoll. -X -g any grade may be given to meet the criteria for -X a successful poll. The default being specified -X in conf.h (A). -X This option may be given individually for each -X site to call. -X site the name of the site to be called. As many sites -X as necessary may be specified separated by at least -X one blank. -X Note: any site will be called with the options currently in -X effect. The working order is left to right. Example: -X uupoll -gQ site1 site2 -gZ site3 -n site4 -X site1 and site2 will be called immediate with grade Q -X site3 will be called immediate with grade Z.

" ] " -.PP -or simply, -.PP -.B uurate -.PP -for a traffic summary report. -.SH DESCRIPTION -The -.I uurate -command provides tabular summary reports on the operation of the -Taylor UUCP system. Data is taken from the currently active log -files, standard input, or from a list of log files given on the -command line. Output is in the form of tabular reports summarizing -call, file transfer, and command execution -.RI "(" "uuxqt" ")" -activity. -.PP -The log and stats files given to -.I uurate -must be in the ``Taylor'' or ``V2'' format. Also, note that call and file -transfer activities are logged in separate files, nominally called -.I Log -and -.I Stats, -respectively. For reports to be meaningful, the -.I Log -and -.I Stats -files should be given to -.I uurate -together, and cover the same time period. -.PP -If neither the -.B \-i -or -.B \-I -option nor any -.I logfile -options are given, -.I uurate -defaults to taking its input from the current Taylor -.I Log -and -.I Stats -files. The names are either as defined at compilation time, in case -there is no config file, or taken from the arguments of the keywords -.I logfile -and -.I statfile -when encountered in the config file. -This is the normal mode of operation. -.PP -The reporting options described below can be used to select -the set of reports desired. If no options are given, a summary -report is displayed. If there is no relevant data for a particular -report or host, that report or host will be suppressed. -.SH OPTIONS -The following options may be given to -.I uurate: -.TP 5 -.B \-a -All reports. Identical to -.B \-cfexp. -.TP 5 -.B \-c -Report on call statistics. Requires data from a -.I Log -file. -.TP 5 -.B \-d -will print the default config file to be used. -.TP 5 -.B \-e -Report on efficiency (total connect time versus time spent transferring -files). Requires data from both a -.I Log -and a -.I Stats -file, and they must span the same time period. -.TP 5 -.B \-f -Report on file transfer statistics. Requires data from a -.I Stats -file. -.TP 5 -.B \-h -will print a short help information. -.TP 5 -.B \-i -tells uurate to read any logfile information from standard input. -.TP 5 -.B \-p -report on protocol errors and packets sent/received -.TP 5 -.B \-q -do not print the Environment information, -.TP 5 -.B \-t -All reports. Identical to -.B \-cfexp. -plus the -.B Compact summary. -.TP 5 -.B \-v -will print the version id string -.TP 5 -.B \-x -Report on remote execution requests (e.g., -.IR rmail ")." -Requires data from a -.I Log -file. -.TP 5 -.BI "\-s " "host" -Restrict report output to -.I host. -.TP 5 -.BI "\-I " "config file" -an alternate config file may be passed by this option. -.SH "DESCRIPTION OF REPORTS" -There are four reports available: the call, file transfer, efficiency, -and remote execution reports. Each may be selected by a command line -option. All reports may be selected via the options -.B \-a -or -.B \-t. -If no report selection options are given, -.I uurate -displays a compact traffic summary report (see below). -.SS "Summary report" -If no report options are given, -.I uurate -displays a traffic summary report. This is particularly useful in daily -.I cron -jobs which report on errors and the like. Traffic statistics for each -active system is reported on a single line. If more than one system was -active, a 'totals' line is included at the end of the report. -.SS "Protocol packet report" -The protocol report gives statistics on min/max packet and window sizes -used during transmission. Further on data is collected for packets -transferred. The data is collected for each host/protocol type. -The fields are described below: -.PP -.br -.nf -.in +.3i -.ta 1.0i -.BR "site " "UUCP node name of neighbor host system," -.BR "typ " "Type of protocol used" -.BR "Min " "minimum packet/window size" -.BR "Max " "maximum packet/window size" -.BR "sent " "packets sent" -.BR "resent " "packets resent" -.BR "received " "packets received" -.in -.3 -.SS "Protocol error report" -The protocol report gives statistics on packet errors -during transmission.

" ] " -.PP -where -.I scriptfile -is the name of a file containing an -.I xchat -script. If -.I scriptfile -begins with ``/'', then it is assumed to be a full path name for the -script file. If not, a configuration-dependent default directory path -(usually -.B "/usr/local/conf/uucp/" -) is prepended to the script file name. Normally, the default path -is the same as that for the Taylor UUCP configuration files. -.SH DESCRIPTION -.I Xchat -is a general-purpose dialing and login program designed for use -with Taylor UUCP as a ``chat-program'', taking the place (or -augmenting) the built-in chat scripting facility. It provides the -ability to closely control timeouts, multiple simultaneous ``expect'' -strings with separate actions, extended terminal control, modem -command character pacing, and more. -.PP -When used in conjunction with Taylor UUCP's -configuration features, -.I xchat -can provide you the ability to manage the most intricate login, -dial and hangup needs. The scripts are written in a shell-like (well, -sort-of) style with labels, commands, and parameters, easing the task -of writing procedures for complex terminal communications situations. -.PP -Because -.I xchat -assumes that it is connected to the terminal device via stdin/stdout, -you can easily debug scripts by invoking it from the shell and -responding to the script from the keyboard. A debug logging facility -is included, with the debug output going to a separate user-specified -file. This makes it easy to debug connection problems without wading -through large -.I uucico -log and debug files. -.PP -Formally, a script describes a state machine; -.I xchat -interprets the script and does what the state machine -tells it to. This section will be much easier to understand -if you obtain listings of the script files supplied with -.I xchat. -.SH "SCRIPT FILE FORMAT" -Script files are ordinary text files containing comments, labels, -and statements. Blank lines are ignored. -Comments are denoted by leading ``#'' -characters. Some statements (those which do not end with an -``extended string'' argument; see below) can also have trailing -comments. -.PP -.I Labels -begin in column one and are ended by colons (:). A label -specifies a state name. All lines between a pair of labels are -the statements for a single state. -.PP -Processing always begins at the head of the script (no leading -state name is necessary). -.PP -.I Statements -are divided into two categories, ``action'' and ``expect''. -When a state is entered, all of its actions are performed in the -order in which they appear in the file. -.PP -A -.I transition -to another state may occur for any of three reasons: -.IP (1) 5 -One of the actions may cause a transition to -another state, in which case the rest of the -current state's actions are skipped. -Processing resumes with the first action -statement of the new state. -.IP (2) 5 -If none of the actions cause a state -transition, and there are no expects in the -state, processing ``falls through'' to the next -state in the file. -.IP (3) 5 -If none of the actions cause a state -transition, but there are expects in the -state, the state machine pauses until one of -the expects is ``satisfied''. It then transitions -to the state named in the expect -statement. -.PP -Finally, there are two action statements which, when executed, -cause the script to exit. -.SH "SCRIPT FILE STATEMENTS" -This section describes all of the statements that may appear in script -files, except for a few special action statements. Those are described -in a later section, ``Overriding Defaults''. -.PP -Some statements accept one or two arguments, referred to in the -following descriptions as -.IR int ", " ns ", " str ", or " -.IR xstr ", to" -indicate whether the argument is an integer, a new state name, a -string, or an ``extended string'' (described in a later section). -.PP -For all statements that accept two arguments, the first is the -name of a new state, and the second specifies a condition or -reason for changing to the new state. -.SS "Termination And Informational Statements" -These statements are used to place entries into the Taylor UUCP -.I Log -file, and to cause -.I xchat -to exit with successful or failure status. It is also possible to open a -separate -.I debug -log file and control the level of tracing and error reporting that will go -into that log file. This is very useful in debugging -.I xchat -scripts. -.br -.ta 1.0i 1.5i 2.0i -.TP 2.0i -.B failed -Exit script with ``failed'' status. This causes -.I xchat -to exit with status 0. -.TP 2.0i -.B success -Exit script with ``success'' status. This causes -.I xchat -to exit with status 1. -.TP 2.0i -.BI "log " xstr -Send informational message -.I xstr -to standard error. When used with Taylor UUCP, this is the -.I Log -file for the -.I uucico -program. -.TP 2.0i -.BI "logerr " xstr -Send message -.I xstr -to standard error, with ``ERROR:'' indicator. When used -with Taylor UUCP, this is the -.I Log -file for the -.I uucico -program. -.TP 2.0i -.BI "dbgfile " xstr -Open script debugging file -.I xstr. -If -.I xstr -begins with ``/'', it is assumed to be an absolute path name for the -debugging file. If not, then a configuration-dependent default directory -path (usually -.B "/usr/spool/uucp" -) is prepended to -.I xstr. -Normally the default path is that of the directory where Taylor UUCP -puts its log files. -The debugging file is used to capture a detailed log of the data sent -and received, errors encountered, and a trace of script execution. -The various types of logging are controlled by the -.I "debug mask," -described next. -.B Note: -A new log file is created each time -.I xchat -runs. Use the -.B log -and -.B loge -commands to log -continuous information onto standard out, which is connected -to the Taylor UUCP -.I Log -file when -.I xchat -is run by the Taylor -.I uucico. -.TP 2.0i -.BI "dbgset " int -Set the bits specified in -.I int -in the debugging mask. The value in -.I int -is ``or''ed into the mask. Set bit 0 (value \= 1) for error messages, -bit 1 (value \= 2) for dial, login and init errors, bit 2 (value \= 4) -for dial, login and init trace with character I/O, and bit 3 (value \= 8) -for script processing internals. Normally, you will just turn it all on -with a value of 15. -.TP 2.0i -.BI "dbgclr " int -Clear the bits specified in -.I int -from the debugging mask. -.TP 2.0i -.BI "debug " xstr -Write -.I -xstr -into the debug log. The entry will be enclosed in angle brackets. -.TP 2.0i -.BI "debuge " xstr -Write -.I xstr -into the debug log with ``ERROR: '' prepended. The entry will be enclosed -in angle brackets. -.SS "Sending Data" -These statements are used to transmit data to standard out (the tty or TCP -port when used with Taylor UUCP). -.I -No implied carriage returns are sent. -You must include a \\r if you want a carriage return in the string -sent by the -.B send -command. If you want a return sent after -.B dial -or -.B sendstr, -you must send it with a separate -.B send -command. -.TP 2.0i -.B dial -Send the string previously set by the -.B telno -command to the serial port. -.B W -and -.B P -characters in the phone number are -converted as described under -.B -Dial Strings, -below. This statement also sets a default -timeout value, as described under the -.B timeout -statement. -.TP 2.0i -.BI "send " xstr -Send the string -.I xstr -to the serial port. -.TP 2.0i -.BI "sendstr " int -The argument of this statement is a digit from 0 -through 7. Send the corresponding string -parameter as passed to -.I xchat -following the script file name. The parameter is interpreted -as an extended string. -.SS "Special Terminal Control Statements" -These statements are used to cause the terminal port to perform some special action, or to change the mode of the port. -.I -The modes of the port are restored to their original settings -.I -by xchat before it exits. -.TP 2.0i -.B flush -Flush the terminal port's input buffer. -.TP 2.0i -.B break -Send a break signal. -.TP 2.0i -.B hangup -Momentarily drop Data Terminal Ready (DTR) on the -serial port, causing the modem to hang up. (Not -usually needed, since -.I uucico -does this at the end of each call.) -.TP 2.0i -.B 7bit -Change the port to strip incoming characters to 7 bits. -.I -This is the default mode. -This mode -is implied when the port has parity enabled, since parity characters -are 7-bits wide. -.TP 2.0i -.B 8bit -Change the port to allow incoming 8-bit characters to be passed -to the script processor. This mode has no effect if parity is -enabled, since parity characters are 7-bits wide. -.TP 2.0i -.B nopar -Change the port to 8-bits, no parity. -.I -This is the default mode. -.TP 2.0i -.B evenpar -Change the port to 7-bits, even parity. -.I -Incoming characters with parity errors are discarded. -.TP 2.0i -.B oddpar -Change the port to 7-bits, odd parity. -.I -Incoming characters with parity errors are discarded. -.SS "Counting, Branching, Timing and Testing Statements" -These statements are used to control the flow of the -.I xchat -script itself, including branching, delays, and counter manipulation. -.TP 2.0i -.BI "sleep " int -Delay for -.I int -milliseconds. -.TP 2.0i -.B zero -Clear the counter. -.TP 2.0i -.B count -Add one to the counter. -.TP 2.0i -.BI "ifgtr " "ns int" -Go to state -.I ns -if counter greater than -.I int. -.TP 2.0i -.BI "goto " ns -Go to state -.I ns -unconditionally. -.TP 2.0i -.BI "ifstr " "ns int" -Go to state -.I ns -if string parameter -.I int -is nonempty. -.TP 2.0i -.BI "ifnstr " "ns int" -Go to state -.I ns -if string parameter -.I int -is empty. -.TP 2.0i -.BI "ifblind " ns -Change to state -.I ns -if the port is ``blind'' without carrier (CD) asserted. -.I -This is not yet implemented, the test always fails. -.TP 2.0i -.BI "ifblgtr " "ns int" -Change to state -.I ns -if the port is ``blind'' without carrier (CD) asserted, and counter -is greater then -.I int. -.I -This is not yet implemented, the test always fails. -.SS "Expect Statements" -Expect statements are usually the last statements that appear in a -given state, though in fact they can appear anywhere within the -state. Even if they appear at the beginning, the script processor -always does all of the action statements first. As a practical -matter, the order of these statements is not significant; they are -all interpreted ``in parallel''. -.TP 2.0i -.BI "expect " "ns xstr" -Change to state -.I ns -if the string specified by -.I xstr -is received from standard input (usually the serial port). -Case is significant, but high-order bits are not -checked. -.TP 2.0i -.BI "expectstr " "ns int" -Change to state -.I ns -if the string specified in parameter -.I int -is received from standard input (usually the serial port). -.I int -must be in the range 0 to 7. -Case is significant, but high-order bits are not -checked. -Useful where a prompt can change in different dial-in lines. -.TP 2.0i -.BI "ifcarr " ns -Change to state -.I ns -if Carrier Detect (CD) is true. -.I -Not currently implemented. Always changes state. -.TP 2.0i -.BI "ifhang " ns -Change to state -.I ns -if a data set hangup occurs (SIGHUP signal received). -.TP 2.0i -.BI "timeout " "ns int" -Change to state -.I ns -if the time (in milliseconds) -given by -.I int -has elapsed without satisfying any -expects. If the time specified is 0, a default -timeout value (calculated from the length and -other characteristics of the most recent dial -string) is used. -.SH "SCRIPT PROCESSING DETAILS" -.SS "Extended Strings" -In the statements that accept string arguments, the strings are -interpreted as -.I -extended strings. -Extended strings begin with -the first nonblank character and continue, including all imbedded -and trailing blanks and other whitespace, until (but not -including) the end of the line in the script file. (There is no -provision for line continuation.) No trailing spaces should be -present between the last ``desired'' character of the string and the -end of the line, as they will be included in the stored string and -sent or expected, just as they appear in the script file. And, -obviously, no trailing comments are permitted! They will just be -stored as part of the string. -.PP -Within an extended string, the following ``escape sequences'' will -be converted as indicated before being sent or expected: -.br -.nf -.in +0.5i -\fB\\d\fR EOT character (control-D) -\fB\\N\fR null character -\fB\\n\fR line feed -\fB\\r\fR carriage return -\fB\\s\fR space -\fB\\t\fR tab -\fB\\\-\fR hyphen -\fB\\\\\fR backslash -\fB\\ooo\fR character with value ooo (in octal) -.in -0.5i -.fi -.PP -Since extended strings in scripts can include embedded spaces, -tabs, etc., these escape sequences are only required in strings -appearing in systems entries, though they may be used in script -files to improve readability. -.PP -The octal-character specification (\\ooo) may have from one to -three octal digits; it is terminated either after the third digit -or when a non-octal character is encountered. But if you want to -specify one of these followed by something that happens to be a -valid octal character (for example, a control-A followed by a 7) -make sure to include all three digits after the \\ . So \\0017 -would become a control-A followed by the Ascii character ``7'', but -\\17 or \\017 would become a control-Y (decimal value 25). \\1S -would convert to a control-A followed by an ``S''. -.PP -Extended strings are stored without a trailing carriage return -unless one is explicitly present in the string (via \\r). -.SS "String Parameters" -The -.B sendstr -statement sends (after conversion from extended string -format) one of the parameters given on the -.I xchat -command line following the script file name. -The parameter is selected by the integer -argument of the statement. -.PP -This allows ``generic'' script files to serve -for many different systems; the string parameters -provide the phone number, username, password, etc. Character -substitutions described under ``extended strings'' above are -performed on these strings. -.PP -The ifstr and ifnstr statements allow further generality in script -files, by testing whether a particular parameter is present in the -systems entry. For example, a single script can be -used both for those systems that require a password and -those that do not. The password is specified as the last argument -in the -.xchat -command; the script can test for this -parameter's existence and skip the password sequence if -the parameter is empty. -.SS "``Wait'' And ``Pause'' Characters In Dial Strings" -An additional conversion is performed on dial strings. Dial strings -are interpreted as extended strings. Then the characters -.B W -and -.B P -within a dial string are interpreted as ``wait for dial -tone'' and ``pause'', and may be converted to other characters. By -default, -.B W -is left alone, and -.B P -is converted to a comma (,); -these are appropriate for Hayes-type modems. The script may -specify other substitutions (see below). -.PP -.B NOTE: -The Taylor UUCP documentation states that the ``wait'' and ``pause'' -characters are ``='' and ``-'', respectively. These are actual characters -understood by some modems. When using -.I xchat -you should put -.B W -and -.B P -in the dial strings you specify in the Taylor configuration files. -This way, the -.I xchat -processor can make the substitution appropriate for the particular -modem in use. Make a separate -.I xchat -script for each modem type, e.g., -.I "dial.hayes" -and specify the translation there. This way, the phone number strings -in the Taylor configuration files can be used with a variety of modems. -.SS "Default Timeouts For Dial Strings" -When a -.B dial -statement is executed, a default timeout value is set. -This is the timeout value used by a subsequent timeout statement -if the statement specifies a timeout value of 0. -.PP -The default timeout is given by: -.br -.nf -.in +2 -\fIctime\fR + (\fIndigits\fR * \fIdgttime\fR) + (\fInwchar\fR * \fIwtime\fR) + (\fInpchar\fR * \fI ptime\fR) -.in -2 -.fi -.PP -where -.I -ndigits, nwchar, -and -.I npchar -are the number of digits, wait characters, and pause characters in -the dial string, and -.I ctime, dgttime, wtime, -and -.I ptime -are 45 seconds, 0.1 seconds, 10 seconds, and 2 seconds, -respectively. -All of these times may be changed as specified below under -``Overriding Defaults.'' -.SS "Trailing Carriage Returns Not Assumed" -In the -.B dial -and -.B sendstr -statements, the dial string or -parameter is sent with no trailing carriage return; -if a carriage return must be sent after one of these, a separate -send statement must provide it. -.SH "OVERRIDING DEFAULTS" -The script processor sets several default values. The following -statements, which override these defaults, may be useful in -certain circumstances. -.TP 2.0i -.BI "chrdly " int -Since many modems cannot accept dialing commands -at full ``computer speed'', the script processor -sends all strings with a brief inter-character -delay. This statement specifies the delay time, -in milliseconds. The default is 100 (0.1 second). -.TP 2.0i -.BI "pchar " str -Specifies the character to which -.BR P s -in the -dial string should be converted. Default is -``,'', for use with Hayes-type modems. -.TP 2.0i -.BI "ptime " int -Specifies the time, in milliseconds, to allow in -the default timeout for each pause character in -the dial string. Default is 2000 (2 seconds). -.TP 2.0i -.BI "wchar " str -Specifies the character to which -.BR W s -in the -dial string should be converted. Default is -``W'', for Hayes modems. -.TP 2.0i -.BI "wtime " int -Specifies the time, in milliseconds, to allow in -the default timeout for each wait-for-dialtone -character in the dial string. Default is 10000 -(10 seconds). -.TP 2.0i -.BI "dgttime " int -Specifies the time, in milliseconds, to allow in -the default timeout for each digit character in -the dial string. Default is 100 (0.1 second). -.TP 2.0i -.BI "ctime " int -Specifies the time, in milliseconds, to allow in -the default timeout for carrier to appear after -the dial string is sent. Default is 45000 (45 -seconds). -.SH "SEE ALSO" -uucico(8) for Taylor UUCP, and documentation for Taylor UUCP. -.SH AUTHOR -Robert B.

In the meantime, here is a very brief one that concentrates -on the programs provided by Taylor UUCP. - -Taylor UUCP is a complete UUCP package. It is covered by the GNU Public -License, which means that the source code is always available. It is -composed of several programs; most of the names of these programs are -based on earlier UUCP packages. - -@table @code - -@item uucp - -The @code{uucp} program is used to copy file between systems. It is -similar to the standard Unix @code{cp} program, except that you can -refer to a file on a remote system by using @samp{system!} before the -file name. For example, to copy the file @file{notes.txt} to the system -@samp{airs}, you would say @samp{uucp notes.txt airs!~/notes.txt}. In -this example @samp{~} is used to name the UUCP public directory on -@samp{airs}. For more details, see @ref{Invoking uucp, uucp}. - -@item uux - -The @code{uux} program is used to request the execution of a program on -a remote system. This is how mail and news are transferred over UUCP. -As with @code{uucp}, programs and files on remote systems may be named -by using @samp{system!}. For example, to run the @code{rnews} program -on @samp{airs}, passing it standard input, you would say @samp{uux - -airs!rnews}. The @samp{-} means to read standard input and set things -up such that when @code{rnews} runs on @samp{airs} it will receive the -same standard input. For more details, see @ref{Invoking uux, uux}. - -@end table - -Neither @code{uucp} nor @code{uux} actually do any work immediately. -Instead, they queue up requests for later processing. They then start a -daemon process which processes the requests and calls up the appropriate -systems. Normally the system will also start the daemon periodically to -check if there is any work to be done. The advantage of this approach -is that it all happens automatically. You don't have to sit around -waiting for the files to be transferred. The disadvantage is that if -anything goes wrong it might be a while before anybody notices. - -@table @code - -@item uustat - -The @code{uustat} program does many things. By default it will simply -list all the jobs you have queued with @code{uucp} or @code{uux} that -have not yet been processed. You can use @code{uustat} to remove any of -your jobs from the queue. You can also it use it to show the status of -the UUCP system in various ways, such as showing the connection status -of all the remote systems your system knows about. The system -administrator can use @code{uustat} to automatically discard old jobs -while sending mail to the user who requested them. For more details, -see @ref{Invoking uustat, uustat}. - -@item uuname - -The @code{uuname} program by default lists all the remote systems your -system knows about. You can also use it to get the name of your local -system. It is mostly useful for shell scripts. For more details, see -@ref{Invoking uuname, uuname}. - -@item uulog - -The @code{uulog} program can be used to display entries in the UUCP log -file. It can select the entries for a particular system or a particular -user. You can use it to see what has happened to your queued jobs in -the past. For more details, see @ref{Invoking uulog, uulog}. - -@item uuto -@item uupick - -@code{uuto} is a simple shell script interface to @code{uucp}. It will -transfer a file, or the contents of a directory, to a remote system, and -notify a particular user on the remote system when it arrives. The -remote user can then retrieve the file(s) with @code{uupick}. For more -details, see @ref{Invoking uuto, uuto}, and see @ref{Invoking uupick, -uupick}. - -@item cu - -The @code{cu} program can be used to call up another system and -communicate with it as though you were directly connected. It can also -do simple file transfers, though it does not provide any error checking. -For more details, @ref{Invoking cu, cu}. - -@end table - -These eight programs just described, @code{uucp}, @code{uux}, -@code{uuto}, @code{uupick}, @code{uustat}, @code{uuname}, @code{uulog}, -and @code{cu} are the user programs provided by Taylor UUCP@. -@code{uucp}, @code{uux}, and @code{uuto} add requests to the work queue, -@code{uupick} extracts files from the UUCP public directory, -@code{uustat} examines the work queue, @code{uuname} examines the -configuration files, @code{uulog} examines the log files, and @code{cu} -just uses the UUCP configuration files. - -The real work is actually done by two daemon processes, which are -normally run automatically rather than by a user. - -@table @code - -@item uucico - -The @code{uucico} daemon is the program which actually calls the remote -system and transfers files and requests. @code{uucico} is normally -started automatically by @code{uucp} and @code{uux}. Most systems will -also start it periodically to make sure that all work requests are -handled. @code{uucico} checks the queue to see what work needs to be -done, and then calls the appropriate systems. If the call fails, -perhaps because the phone line is busy, @code{uucico} leaves the -requests in the queue and goes on to the next system to call. It is -also possible to force @code{uucico} to call a remote system even if -there is no work to be done for it, so that it can pick up any work that -may be queued up remotely. For more details, see @ref{Invoking uucico, -uucico}. - -@need 1000 -@item uuxqt - -The @code{uuxqt} daemon processes execution requests made by the -@code{uux} program on remote systems. It also processes requests made -on the local system which require files from a remote system. It is -normally started by @code{uucico}. For more details, see @ref{Invoking -uuxqt, uuxqt}. - -@end table - -Suppose you, on the system @samp{bantam}, want to copy a file to the -system @samp{airs}. You would run the @code{uucp} command locally, with -a command like @samp{uucp notes.txt airs!~/notes.txt}. This would queue -up a request on @samp{bantam} for @samp{airs}, and would then start the -@code{uucico} daemon. @code{uucico} would see that there was a request -for @samp{airs} and attempt to call it. When the call succeeded, -another copy of @code{uucico} would be started on @samp{airs}. The two -copies of @code{uucico} would tell each other what they had to do and -transfer the file from @samp{bantam} to @samp{airs}. When the file -transfer was complete the @code{uucico} on @samp{airs} would move it -into the UUCP public directory. - -UUCP is often used to transfer mail. This is normally done -automatically by mailer programs. When @samp{bantam} has a mail message -to send to @samp{ian} at @samp{airs}, it executes @samp{uux - airs!rmail -ian} and writes the mail message to the @code{uux} process as standard -input. The @code{uux} program, running on @samp{bantam}, will read the -standard input and store it, as well as the @code{rmail} request itself, -on the work queue for @samp{airs}. @code{uux} will then start the -@code{uucico} daemon. The @code{uucico} daemon will call up -@samp{airs}, just as in the @code{uucp} example, and transfer the work -request and the mail message. The @code{uucico} daemon on @samp{airs} -will put the files on a local work queue. When the communication -session is over, the @code{uucico} daemon on @samp{airs} will start the -@code{uuxqt} daemon. @code{uuxqt} will see the request on the work -queue, and will run @samp{rmail ian} with the mail message as standard -input. The @code{rmail} program, which is not part of the UUCP package, -is then responsible for either putting the message in the right mailbox -on @samp{airs} or forwarding the message on to another system. - -Taylor UUCP comes with a few other programs that are useful when -installing and configuring UUCP. - -@table @code - -@item uuchk - -The @code{uuchk} program reads the UUCP configuration files and displays -a rather lengthy description of what it finds. This is useful when -configuring UUCP to make certain that the UUCP package will do what you -expect it to do. For more details, see @ref{Invoking uuchk, uuchk}. - -@item uuconv - -The @code{uuconv} program can be used to convert UUCP configuration -files from one format to another. This can be useful for administrators -converting from an older UUCP package. Taylor UUCP is able to read and -use old configuration file formats, but some new features can not be -selected using the old formats. For more details, see @ref{Invoking -uuconv, uuconv}. - -@item uusched - -The @code{uusched} script is provided for compatibility with older UUCP -releases. It starts @code{uucico} to call, one at a time, all the -systems for which work has been queued. For more details, see -@ref{Invoking uusched, uusched}. - -@item tstuu - -The @code{tstuu} program is a test harness for the UUCP package; it can -help check that the package has been configured and compiled correctly. -However, it uses pseudo-terminals, which means that it is less portable -than the rest of the package. If it works, it can be useful when -initially installing Taylor UUCP. For more details, see @ref{Testing -the Compilation, tstuu}. - -@end table - -@node Invoking the UUCP Programs, Installing Taylor UUCP, Introduction, Top -@chapter Invoking the UUCP Programs - -This chapter describes how to run the UUCP programs. - -@menu -* Standard Options:: Standard Options for the UUCP Programs -* Invoking uucp:: Invoking uucp -* Invoking uux:: Invoking uux -* Invoking uustat:: Invoking uustat -* Invoking uuname:: Invoking uuname -* Invoking uulog:: Invoking uulog -* Invoking uuto:: Invoking uuto -* Invoking uupick:: Invoking uupick -* Invoking cu:: Invoking cu -* Invoking uucico:: Invoking uucico -* Invoking uuxqt:: Invoking uuxqt -* Invoking uuchk:: Invoking uuchk -* Invoking uuconv:: Invoking uuconv -* Invoking uusched:: Invoking uusched -@end menu - -@node Standard Options, Invoking uucp, Invoking the UUCP Programs, Invoking the UUCP Programs -@section Standard Options - -All of the UUCP programs support a few standard options. - -@table @samp -@item -x type -@itemx --debug type -Turn on particular debugging types.

An empty system name is -taken as the local system; this form must be used to transfer a file to -a command being executed on a remote system.

Note that the redirection characters must be quoted so that -they are passed to @code{uux} rather than interpreted by the shell. -Append redirection (@samp{>>}) does not work. - -All specified files are gathered together into a single directory -before execution of the command begins. This means that each file -must have a distinct name. For example, -@example -uux 'sys1!diff sys2!~user1/foo sys3!~user2/foo >!foo.diff' -@end example -will fail because both files will be copied to @samp{sys1} and stored -under the name @file{foo}. - -Arguments may be quoted by parentheses to avoid interpretation of -exclamation points. This is useful when executing the @code{uucp} -command on a remote system. - -Most systems restrict the commands which may be executed using -@samp{uux}. Many permit only the execution of @samp{rmail} and -@samp{rnews}. - -A request to execute an empty command (e.g., @samp{uux sys!}) will -create a poll file for the specified system; see @ref{Calling Other -Systems} for an example of why this might be useful. - -@node uux Options, uux Examples, uux Description, Invoking uux -@subsection uux Options - -The following options may be given to @code{uux}. - -@table @samp -@item - -@itemx -p -@itemx --stdin -Read standard input up to end of file, and use it as the standard input -for the command to be executed. - -@item -c -@itemx --nocopy -Do not copy local files to the spool directory.

Also, a remote system may have work -queued up for your system, but may not be calling you for some reason -(perhaps you have agreed that your system should always place the call). -To make sure that work gets transferred between the systems withing a -reasonable time period, you should arrange to periodically invoke -@code{uucico}. - -These periodic invocations are normally triggered by entries in the -@file{crontab} file. The exact format of @file{crontab} files, and how -new entries are added, varies from system to system; check your local -documentation (try @samp{man cron}). - -To attempt to call all systems with outstanding work, use the command -@samp{uucico -r1}. To attempt to call a particular system, use the -command @samp{uucico -s @var{system}}. To attempt to call a particular -system, but only if there is work for it, use the command @samp{uucico --C -s @var{system}}. (@pxref{Invoking uucico}). - -A common case is to want to try to call a system at a certain time, with -periodic retries if the call fails. A simple way to do this is to -create an empty UUCP command file, known as a @dfn{poll file}. If a -poll file exists for a system, then @samp{uucico -r1} will place a call -to it. If the call succeeds, the poll file will be deleted. - -A poll file can be easily created using the @samp{uux} command, by -requesting the execution of an empty command. To create a poll file for -@var{system}, just do something like this: -@example -uux -r @var{system}! -@end example -The @samp{-r} tells @samp{uux} to not start up @samp{uucico} -immediately. Of course, if you do want @samp{uucico} to start up right -away, omit the @samp{-r}; if the call fails, the poll file will be left -around to cause a later call. - -For example, I use the following crontab entries locally: - -@example -45 * * * * /bin/echo /usr/lib/uucp/uucico -r1 | /bin/su uucpa -40 4,10,15 * * * /usr/bin/uux -r uunet! -@end example - -Every hour, at 45 minutes past, this will check if there is any work to -be done, and, if there is, will call the appropriate system.

The commands permitted in -each file are described in detail below. This section is a brief -description of some of the different types of files. - -The @file{config} file is the main configuration file. It describes -general information not associated with a particular remote system, such -as the location of various log files. There are reasonable defaults for -everything that may be specified in the @file{config} file, so you may -not actually need one on your system. - -There may be only one @file{config} file, but there may be one or more -of each other type of file. The default is one file for each type, but -more may be listed in the @file{config} file. - -The @file{sys} files are used to describe remote systems. Each remote -system to which you connect must be listed in a @file{sys} file. A -@file{sys} file will include information for a system, such as the speed -(baud rate) to use, or when to place calls. - -For each system you wish to call, you must describe one or more ports; -these ports may be defined directly in the @file{sys} file, or they may -be defined in a @file{port} file. - -The @file{port} files are used to describe ports. A port is a -particular hardware connection on your computer. You would normally -define as many ports as there are modems attached to your computer. A -TCP connection is also described using a port. - -The @file{dial} files are used to describe dialers. Dialer is -essentially another word for modem. The @file{dial} file describes the -commands UUCP should use to dial out on a particular type of modem. You -would normally define as many dialers as there are types of modems -attached to your computer. For example, if you have three Telebit -modems used for UUCP, you would probably define three ports and one -dialer. - -There are other types of configuration files, but these are the -important ones. The other types are described below. - -@node Configuration File Format, Configuration Examples, Configuration Overview, Configuration Files -@section Configuration File Format - -All the configuration files follow a simple line-oriented -@samp{@var{keyword} @var{value}} format. Empty lines are ignored, as -are leading spaces; unlike HDB, lines with leading spaces are read. The -first word on each line is a keyword. The rest of the line is -interpreted according to the keyword. Most keywords are followed by -numbers, boolean values or simple strings with no embedded spaces. - -The @kbd{#} character is used for comments. Everything from a @kbd{#} -to the end of the line is ignored unless the @kbd{#} is preceded by a -@kbd{\} (backslash); if the @kbd{#} is preceeded by a @kbd{\}, the -@kbd{\} is removed but the @kbd{#} remains in the line. This can be -useful for a phone number containing a @kbd{#}. To enter the sequence -@samp{\#}, use @samp{\\#}. - -The backslash character may be used to continue lines. If the last -character in a line is a backslash, the backslash is removed and the -line is continued by the next line. The second line is attached to the -first with no intervening characters; if you want any whitespace between -the end of the first line and the start of the second line, you must -insert it yourself. - -However, the backslash is not a general quoting character. For example, -you cannot use it to get an embedded space in a string argument. - -Everything after the keyword must be on the same line. A @var{boolean} -may be specified as @kbd{y}, @kbd{Y}, @kbd{t}, or @kbd{T} for true and -@kbd{n}, @kbd{N}, @kbd{f}, or @kbd{F} for false; any trailing characters -are ignored, so @code{true}, @code{false}, etc., are also acceptable. - -@node Configuration Examples, Time Strings, Configuration File Format, Configuration Files -@section Examples of Configuration Files - -This section provides few typical examples of configuration files. -There are also sample configuration files in the @file{sample} -subdirectory of the distribution. - -@menu -* config File Examples:: Examples of the Main Configuration File -* Leaf Example:: Call a Single Remote Site -* Gateway Example:: The Gateway for Several Local Systems -@end menu - -@node config File Examples, Leaf Example, Configuration Examples, Configuration Examples -@subsection config File Examples -@cindex config file examples - -To start with, here are some examples of uses of the main configuration -file, @file{config}. For a complete description of the commands that -are permitted in @file{config}, see @ref{config File}. - -In many cases you will not need to create a @file{config} file at all. -The most common reason to create one is to give your machine a special -UUCP name. Other reasons might be to change the UUCP spool directory, -or to permit any remote system to call in. - -If you have an internal network of machines, then it is likely that the -internal name of your UUCP machine is not the name you want to use when -calling other systems. For example, here at @file{airs.com} our -mail/news gateway machine is named @file{elmer.airs.com} (it is one of -several machines all named @file{@var{localname}.airs.com}). If we did -not provide a @file{config} file, then our UUCP name would be -@file{elmer}; however, we actually want it to be @file{airs}. -Therefore, we use the following line in @file{config}: - -@example -nodename airs -@end example - -@cindex changing spool directory -@cindex spool directory, changing -The UUCP spool directory name is set in @file{policy.h} when the code is -compiled.

The @code{unknown} -command is followed by any command that may appear in the system file; -for full details, see @ref{sys File}. - -I will show two possible anonymous UUCP configurations.

Chat scripts are made up of -pairs of strings. The program waits until it sees the first string, -known as the @dfn{expect} string, and then sends out the second string, -the @dfn{send} string. - -Each chat script is defined using a set of commands. These commands -always end in a string beginning with @code{chat}, but may start with -different strings. For example, in the @file{sys} file there is one set -of commands beginning with @code{chat} and another set beginning with -@code{called-chat}. The prefixes are only used to disambiguate -different types of chat scripts, and this section ignores the prefixes -when describing the commands. - -@table @code - -@item chat @var{strings} -@findex chat - -Specify a chat script. The arguments to the @code{chat} command are -pairs of strings separated by whitespace. The first string of each pair -is an expect string, the second is a send string. The program will wait -for the expect string to appear; when it does, the program will send the -send string. If the expect string does not appear within a certain -number of seconds (as set by the @code{chat-timeout} command), the chat -script fails and, typically, the call is aborted. If the final expect -string is seen (and the optional final send string has been sent), the -chat script is successful. - -An expect string may contain additional subsend and subexpect strings, -separated by hyphens. If the expect string is not seen, the subsend -string is sent and the chat script continues by waiting for the -subexpect string. This means that a hyphen may not appear in an expect -string; on an ASCII system, use @samp{\055} instead. - -An expect string may simply be @samp{""}, meaning to skip the expect -phase. Otherwise, the following escape characters may appear in expect -strings: - -@table @samp -@item \b -a backspace character -@item \n -a newline or line feed character -@item \N -a null character (for HDB compatibility) -@item \r -a carriage return character -@item \s -a space character -@item \t -a tab character -@item \\ -a backslash character -@item \@var{ddd} -character @var{ddd}, where @var{ddd} are up to three octal digits -@item \x@var{ddd} -character @var{ddd}, where @var{ddd} are hexadecimal digits. -@end table - -As in C, there may be up to three octal digits following a backslash, -but the hexadecimal escape sequence continues as far as possible. To -follow a hexadecimal escape sequence with a hex digit, interpose a send -string of @samp{""}. - -A chat script expect string may also specify a timeout. This is done by -using the escape sequence @samp{\W@var{seconds}}. This escape sequence -may only appear at the very end of the expect string. It temporarily -overrides the timeout set by @code{chat-timeout} (described below) only -for the expect string to which it is attached. - -A send string may simply be @samp{""} to skip the send phase. -Otherwise, all of the escape characters legal for expect strings may be -used, and the following escape characters are also permitted: - -@table @samp -@item EOT -send an end of transmission character (@kbd{^D}) -@item BREAK -send a break character (may not work on all systems) -@item \c -suppress trailing carriage return at end of send string -@item \d -delay sending for 1 or 2 seconds -@item \e -disable echo checking -@item \E -enable echo checking -@item \K -same as @samp{BREAK} (for HDB compatibility) -@item \p -pause sending for a fraction of a second -@end table - -Some specific types of chat scripts also define additional escape -sequences that may appear in the send string. For example, the login -chat script defines @samp{\L} and @samp{\P} to send the login name and -password, respectively. - -A carriage return will be sent at the end of each send string, unless -the @kbd{\c} escape sequence appears in the string. Note that some UUCP -packages use @kbd{\b} for break, but here it means backspace. - -Echo checking means that after writing each character the program will -wait until the character is echoed. Echo checking must be turned on -separately for each send string for which it is desired; it will be -turned on for characters following @kbd{\E} and turned off for characters -following @kbd{\e}. - -@item chat-timeout @var{number} -@findex chat-timeout - -The number of seconds to wait for an expect string in the chat script, -before timing out and sending the next subsend, or failing the chat -script entirely. The default value is 10 for a login chat or 60 for any -other type of chat. - -@item chat-fail @var{string} -@findex chat-fail - -If the @var{string} is seen at any time during a chat script, the chat -script is aborted. The string may not contain any whitespace -characters: escape sequences must be used for them. Multiple -@code{chat-fail} commands may appear in a single chat script. The -default is to have none. - -This permits a chat script to be quickly aborted if an error string is -seen. For example, a script used to dial out on a modem might use the -command @samp{chat-fail BUSY} to stop the chat script immediately if the -string @samp{BUSY} was seen. - -The @code{chat-fail} strings are considered in the order they are -listed, so if one string is a suffix of another the longer one should be -listed first. This affects the error message which will be logged. Of -course, if one string is contained within another, but is not a suffix, -the smaller string will always be found before the larger string could -match. - -@item chat-seven-bit @var{boolean} -@findex chat-seven-bit - -If the argument is true, all incoming characters are stripped to seven -bits when being compared to the expect string. Otherwise all eight bits -are used in the comparison. The default is true, because some Unix -systems generate parity bits during the login prompt which must be -ignored while running a chat script. This has no effect on any -@code{chat-program}, which must ignore parity by itself if necessary. - -@item chat-program @var{strings} -@findex chat-program - -Specify a program to run before executing the chat script. This program -could run its own version of a chat script, or it could do whatever it -wants. If both @code{chat-program} and @code{chat} are specified, the -program is executed first followed by the chat script. - -The first argument to the @code{chat-program} command is the program -name to run.

The -following escape sequences are recognized in the arguments: - -@table @kbd -@item \Y -port device name -@item \S -port speed -@item \\ -backslash -@end table - -Some specific uses of @code{chat-program} define additional escape -sequences. - -Arguments other than escape sequences are passed exactly as they appear -in the configuration file, except that sequences of whitespace are -compressed to a single space character (this exception may be removed in -the future). - -If the @code{chat-program} command is not used, no program is run. - -On Unix, the standard input and standard output of the program will be -attached to the port in use. Anything the program writes to standard -error will be written to the UUCP log file. No other file descriptors -will be open. If the program does not exit with a status of 0, it will -be assumed to have failed. This means that the dialing programs used by -some versions of HDB may not be used directly, but you may be able to -run them via the @code{dialHDB} program in the @file{contrib} directory. - -The program will be run as the @code{uucp} user, and the environment -will be that of the process that started @code{uucico}, so care must be -taken to maintain security. - -No search path is used to find the program; a full file name must be -given. If the program is an executable shell script, it will be passed -to @file{/bin/sh} even on systems which are unable to execute shell -scripts. - -@end table - -Here is a simple example of a chat script that might be used to reset a -Hayes compatible modem. - -@example -chat "" ATZ OK-ATZ-OK -@end example - -The first expect string is @samp{""}, so it is ignored.

See the -@code{time} command, above, for more details. - -Note that the @code{timegrade} command serves two purposes: 1) if there -is no job of sufficiently high grade the system will not be called, and -2) if the system is called anyway (because the @samp{-s} switch was -given to @code{uucico}) only jobs of sufficiently high grade will be -transferred.

It is a streaming protocol, so, while it can -be used on a serial port, the port must be completely reliable and flow -controlled; many aren't. @xref{f Protocol}. - -The @samp{v} protocol is the @samp{g} protocol as used by the DOS -program UUPC/Extended. It is provided only so that UUPC/Extended users -can use it; there is no particular reason to select it. @xref{v -Protocol}. - -The @samp{y} protocol is an efficient streaming protocol. It does error -checking, but when it detects an error it immediately aborts the -connection. This requires a reliable, flow controlled, eight-bit -connection. In practice, it is only useful on a connection that is -nearly always error-free. Unlike the @samp{t} and @samp{e} protocols, -the connection need not be entirely error-free, so the @samp{y} protocol -can be used on a serial port. @xref{y Protocol}. - -The protocols will be considered in the order shown above. This means -that if neither the @code{seven-bit} nor the @code{reliable} command are -used, the @samp{t} protocol will be used over a TCP connection and the -@samp{i} protocol will be used over any other type of connection -(subject, of course, to what is supported by the remote system; it may -be assumed that all systems support the @samp{g} protocol). - -Note that currently specifying both @samp{seven-bit true} and -@samp{reliable false} will not match any protocol. If this occurs -through a combination of port and dialer specifications, you will have -to use the @code{protocol} command for the system or no protocol will be -selected at all (the only reasonable choice would be @samp{protocol f}). - -A protocol list may also be specified for a port (@pxref{port File}), -but, if there is a list for the system, the list for the port is -ignored. - -@item protocol-parameter @var{character} @var{string} @dots{} -@findex protocol-parameter in sys file - -@var{character} is a single character specifying a protocol. The -remaining strings are a command specific to that protocol which will be -executed if that protocol is used. A typical command is something like -@samp{window 7}. The particular commands are protocol specific. - -The @samp{i} protocol supports the following commands, all of which take -numeric arguments: - -@table @code -@item window -The window size to request the remote system to use. This must be -between 1 and 16 inclusive. The default is 16. -@item packet-size -The packet size to request the remote system to use. This must be -between 1 and 4095 inclusive. The default is 1024. -@item remote-packet-size -If this is between 1 and 4095 inclusive, the packet size requested by -the remote system is ignored, and this is used instead. The default is -0, which means that the remote system's request is honored. -@item sync-timeout -The length of time, in seconds, to wait for a SYNC packet from the remote -system. SYNC packets are exchanged when the protocol is started. The -default is 10. -@item sync-retries -The number of times to retry sending a SYNC packet before giving up. -The default is 6. -@item timeout -The length of time, in seconds, to wait for an incoming packet before -sending a negative acknowledgement. The default is 10. -@item retries -The number of times to retry sending a packet or a negative -acknowledgement before giving up and closing the connection. The -default is 6. -@item errors -The maximum number of errors to permit before closing the connection. -The default is 100. -@item error-decay -The rate at which to ignore errors. Each time this many packets are -received, the error count is decreased by one, so that a long connection -with an occasional error will not exceed the limit set by @code{errors}. -The default is 10. -@item ack-frequency -The number of packets to receive before sending an acknowledgement. The -default is half the requested window size, which should provide good -performance in most cases. -@end table - -The @samp{g}, @samp{G} and @samp{v} protocols support the following -commands, all of which take numeric arguments, except -@code{short-packets} which takes a boolean argument: - -@table @code -@item window -The window size to request the remote system to use. This must be -between 1 and 7 inclusive. The default is 7. -@item packet-size -The packet size to request the remote system to use. This must be a -power of 2 between 32 and 4096 inclusive. The default is 64 for the -@samp{g} and @samp{G} protocols and 1024 for the @samp{v} protocol. -Many older UUCP packages do not support packet sizes larger than 64, and -many others do not support packet sizes larger than 128. Some UUCP -packages will even dump core if a larger packet size is requested. The -packet size is not a negotiation, and it may be different in each -direction. If you request a packet size larger than the remote system -supports, you will not be able to send any files. -@item startup-retries -The number of times to retry the initialization sequence. The default -is 8. -@item init-retries -The number of times to retry one phase of the initialization sequence -(there are three phases). The default is 4. -@item init-timeout -The timeout in seconds for one phase of the initialization sequence. The -default is 10. -@item retries -The number of times to retry sending either a data packet or a request -for the next packet. The default is 6. -@item timeout -The timeout in seconds when waiting for either a data packet or an -acknowledgement. The default is 10. -@item garbage -The number of unrecognized bytes to permit before dropping the -connection. This must be larger than the packet size. The default is -10000. -@item errors -The number of errors (malformed packets, out of order packets, bad -checksums, or packets rejected by the remote system) to permit before -dropping the connection. The default is 100. -@item error-decay -The rate at which to ignore errors. Each time this many packets are -received, the error count is decreased by one, so that a long connection -with an occasional error will not exceed the limit set by @code{errors}. -The default is 10. -@item remote-window -If this is between 1 and 7 inclusive, the window size requested by the -remote system is ignored and this is used instead. This can be useful -when dealing with some poor UUCP packages. The default is 0, which -means that the remote system's request is honored. -@item remote-packet-size -If this is between 32 and 4096 inclusive the packet size requested by -the remote system is ignored and this is used instead. There is -probably no good reason to use this. The default is 0, which means that -the remote system's request is honored. -@item short-packets -If this is true, then the code will optimize by sending shorter packets -when there is less data to send. This confuses some UUCP packages, such -as System V Release 4 (when using the @samp{G} protocol) and Waffle; -when connecting to such a package, this parameter must be set to false. -The default is true for the @samp{g} and @samp{v} protocols and false -for the @samp{G} protocol. -@end table - -The @samp{a} protocol is a Zmodem like protocol contributed by Doug -Evans. It supports the following commands, all of which take numeric -arguments except for @code{escape-control}, which takes a boolean -argument: - -@table @code -@item timeout -Number of seconds to wait for a packet to arrive. The default is 10. -@item retries -The number of times to retry sending a packet. The default is 10. -@item startup-retries -The number of times to retry sending the initialization packet. The -default is 4. -@item garbage -The number of garbage characters to accept before closing the -connection. The default is 2400. -@item send-window -The number of characters that may be sent before waiting for an -acknowledgement. The default is 1024. -@item escape-control -Whether to escape control characters. If this is true, the protocol may -be used over a connection which does not transmit certain control -characters, such as @code{XON} or @code{XOFF}. The connection must -still transmit eight bit characters other than control characters. The -default is false. -@end table - -The @samp{j} protocol can be used over an eight bit connection that will -not transmit certain control characters. It accepts the same protocol -parameters that the @samp{i} protocol accepts, as well as one more: - -@table @code -@item avoid -A list of characters to avoid. This is a string which is interpreted as -an escape sequence (@pxref{Chat Scripts}). The protocol does not have a -way to avoid printable ASCII characters (byte values from 32 to 126, -inclusive); only ASCII control characters and eight-bit characters may -be avoided. The default value is @samp{\021\023}; these are the -characters @code{XON} and @code{XOFF}, which many connections use for -flow control. If the package is configured to use @code{HAVE_BSD_TTY}, -then on some versions of Unix you may have to avoid @samp{\377} as well, -due to the way some implementations of the BSD terminal driver handle -signals. -@end table - -The @samp{f} protocol is intended for use with error-correcting modems -only; it checksums each file as a whole, so any error causes the entire -file to be retransmitted.

The default is 120. -@item retries -How many times to retry sending a file. The default is 2. -@end table - -The @samp{t} and @samp{e} protocols are intended for use over TCP or -some other communication path with end to end reliability, as they do no -checking of the data at all.

This one takes precedence. - -@item seven-bit @var{boolean} [ any type ] -@findex seven-bit in port file - -This is only used during protocol negotiation; if the argument is true, -it forces the selection of a protocol which works across a seven-bit -link. It does not prevent eight bit characters from being transmitted. -The default is false. - -@item reliable @var{boolean} [ any type ] -@findex reliable in port file - -This is only used during protocol negotiation; if the argument is -false, it forces the selection of a protocol which works across -an unreliable communication link. The default is true. It would -be more common to specify this for a dialer rather than a port. - -@item half-duplex @var{boolean} [ any type ] -@findex half-duplex in port file - -If the argument is true, it means that the port only supports -half-duplex connections. This only affects bidirectional protocols, and -causes them to not do bidirectional transfers. - -@item device @var{string} [ modem, direct and tli only ] -@findex device - -Names the device associated with this port. If the device is not named, -the port name is taken as the device. Device names are system -dependent.

The first number is the -minimum speed, the second number is the maximum speed. These numbers -will be used when matching a system which specifies a desired speed. -The simple @code{speed} (or @code{baud}) command is still used to -determine the speed to run at if the system does not specify a speed. -For example, the command @samp{speed-range 300 19200} means that the -port will match any system which uses a speed from 300 to 19200 baud -(and will use the speed specified by the system); this could be combined -with @samp{speed 2400}, which means that when this port is used with a -system that does not specify a speed, the port will be used at 2400 -baud. - -@item carrier @var{boolean} [ modem and direct only ] -@findex carrier in port file - -The argument indicates whether the port supports carrier. - -If a modem port does not support carrier, the carrier detect signal will -never be required on this port, regardless of what the modem chat script -indicates. The default for a modem port is true. - -If a direct port supports carrier, the port will be set to expect -carrier whenever it is used. The default for a direct port is false. - -@item hardflow @var{boolean} [ modem and direct only ] -@findex hardflow - -The argument indicates whether the port supports hardware flow control. -If it does not, hardware flow control will not be turned on for this -port. The default is true.

The default is to output to the normal port -device. - -@item dialer @var{string} [ modem only ] -@findex dialer in port file - -Name a dialer to use. The information is looked up in the dial file. -There is no default. Some sort of dialer information must be specified -to call out on a modem. - -@item dialer @var{string} @dots{} [ modem only ] - -If more than one string follows the @code{dialer} command, the strings -are treated as a command that might appear in the dial file (@pxref{dial -File}). If a dialer is named (by using the first form of this command, -described just above), these commands are ignored. They may be used to -specify dialer information directly in simple situations without needing -to go to a separate file. There is no default. Some sort of dialer -information must be specified to call out on a modem. - -@item dialer-sequence @var{strings} [ modem or tcp or tli only ] -@findex dialer-sequence - -Name a sequence of dialers and tokens (phone numbers) to use. The first -argument names a dialer, and the second argument names a token. The -third argument names another dialer, and so on. If there are an odd -number of arguments, the phone number specified with a @code{phone} -command in the system file is used as the final token. The token is -what is used for @kbd{\D} or @kbd{\T} in the dialer chat script. If the -token in this string is @kbd{\D}, the system phone number will be used; -if it is @kbd{\T}, the system phone number will be used after undergoing -dialcodes translation. A missing final token is taken as @kbd{\D}. - -This command currently does not work if @code{dial-device} is specified; -to handle this correctly will require a more systematic notion of chat -scripts. Moreover, the @code{complete} and @code{abort} chat scripts, -the protocol parameters, and the @code{carrier} and @code{dtr-toggle} -commands are ignored for all but the first dialer. - -This command basically lets you specify a sequence of chat scripts to -use. For example, the first dialer might get you to a local network and -the second dialer might describe how to select a machine from the local -network. This lets you break your dialing sequence into simple modules, -and may make it easier to share dialer entries between machines. - -This command is to only way to use a chat script with a TCP port. This -can be useful when using a modem which is accessed via TCP. - -When this command is used with a TLI port, then if the first dialer is -@samp{TLI} or @samp{TLIS} the first token is used as the address to -connect to. If the first dialer is something else, or if there is no -token, the address given by the @code{address} command is used -(@pxref{Placing the Call}). Escape sequences in the address are -expanded as they are for chat script expect strings (@pxref{Chat -Scripts}). The different between @samp{TLI} and @samp{TLIS} is that the -latter implies the command @samp{stream true}. These contortions are -all for HDB compatibility. Any subsequent dialers are treated as they -are for a TCP port. - -@item lockname @var{string} [ modem and direct only ] -@findex lockname - -Give the name to use when locking this port. On Unix, this is the name -of the file that will be created in the lock directory. It is used as -is, so on Unix it should generally start with @samp{LCK..}. For -example, if a single port were named both @file{/dev/ttycu0} and -@file{/dev/tty0} (perhaps with different characteristics keyed on the -minor device number), then the command @code{lockname LCK..ttycu0} could -be used to force the latter to use the same lock file name as the -former. - -@item service @var{string} [ tcp only ] -@findex service - -Name the TCP port number to use. This may be a number. If not, it will -be looked up in @file{/etc/services}. If this is not specified, the -string @samp{uucp} is looked up in @file{/etc/services}.

This will cause @code{uucico} to prompt with @samp{login:} and -@samp{Password:} and check the results against the UUCP (not the system) -password file (you may want to also use the @samp{-D} switch to avoid a -fork, which in this case is unnecessary). - -@node Security, , UUCP Over TCP, Configuration Files -@section Security - -This discussion of UUCP security applies only to Unix. It is a bit -cursory; suggestions for improvement are solicited. - -UUCP is traditionally not very secure. Taylor UUCP addresses some -security issues, but is still far from being a secure system. - -If security is very important to you, then you should not permit any -external access to your computer, including UUCP. Any opening to the -outside world is a potential security risk. - -When local users use UUCP to transfer files, Taylor UUCP can do little -to secure them from each other. You can allow somewhat increased -security by putting the owner of the UUCP programs (normally -@code{uucp}) into a separate group; the use of this is explained in the -following paragraphs, which refer to this separate group as -@code{uucp-group}. - -When the @code{uucp} program is invoked to copy a file to a remote -system, it will, by default, copy the file into the UUCP spool -directory. When the @code{uux} program is used, the @samp{-C} switch -must be used to copy the file into the UUCP spool directory. In any -case, once the file has been copied into the spool directory, other -local users will not be able to access it. - -When a file is requested from a remote system, UUCP will only permit it -to be placed in a directory which is writable by the requesting user. -The directory must also be writable by UUCP. A local user can create a -directory with a group of @code{uucp-group} and set the mode to permit -group write access. This will allow the file be requested without -permitting it to be viewed by any other user. - -There is no provision for security for @code{uucp} requests (as opposed -to @code{uux} requests) made by a user on a remote system. A file sent -over by a remote request may only be placed in a directory which is -world writable, and the file will be world readable and writable. This -will permit any local user to destroy or replace the contents of the -file. A file requested by a remote system must be world readable, and -the directory it is in must be world readable. Any local user will be -able to examine, although not necessarily modify, the file before it is -sent. - -There are some security holes and race conditions that apply to the -above discussion which I will not elaborate on. They are not hidden -from anybody who reads the source code, but they are somewhat technical -and difficult (though scarcely impossible) to exploit. Suffice it to -say that even under the best of conditions UUCP is not completely -secure. - -For many sites, security from remote sites is a more important -consideration. Fortunately, Taylor UUCP does provide some support in -this area. - -The greatest security is provided by always dialing out to the other -site. This prevents anybody from pretending to be the other site. Of -course, only one side of the connection can do this. - -If remote dialins must be permitted, then it is best if the dialin line -is used only for UUCP. If this is the case, then you should create a -call-in password file (@pxref{Configuration File Names}) and let -@code{uucico} do its own login prompting. For example, to let remote -sites log in on a port named @samp{entry} in the port file (@pxref{port -File}), you might invoke @samp{uucico -e -p entry}. This would cause -@code{uucico} to enter an endless loop of login prompts and daemon -executions. The advantage of this approach is that even if remote users -break into the system by guessing or learning the password, they will -only be able to do whatever @code{uucico} permits them to do. They will -not be able to start a shell on your system. - -If remote users can dial in and log on to your system, then you have a -security hazard more serious than that posed by UUCP. But then, you -probably knew that already. - -Once your system has connected with the remote UUCP, there is a fair -amount of control you can exercise. You can use the @code{remote-send} -and @code{remote-receive} commands to control the directories the remote -UUCP can access. You can use the @code{request} command to prevent the -remote UUCP from making any requests of your system at all; however, if -you do this it will not even be able to send you mail or news. If you -do permit remote requests, you should be careful to restrict what -commands may be executed at the remote system's request. The default is -@code{rmail} and @code{rnews}, which will suffice for most systems. - -If different remote systems call in and they must be granted different -privileges (perhaps some systems are within the same organization and -some are not) then the @code{called-login} command should be used for -each system to require that they use different login names. Otherwise, -it would be simple for a remote system to use the @code{myname} command -and pretend to be a different system. The @code{sequence} command can -be used to detect when one system pretended to be another, but, since -the sequence numbers must be reset manually after a failed handshake, -this can sometimes be more trouble than it's worth. - -@c START-OF-FAQ -@ignore -This chapter is used to generate the comp.mail.uucp UUCP Internals FAQ, -as well as being part of the Taylor UUCP manual.

Taylor UUCP does not use the -word @samp{alarm}, but will instead log messages like @samp{Timed out -waiting for packet}. - -These types of messages mean that the UUCP package has timed out while -waiting for some sort of response from the remote system. If it happens -consistently when trying to transfer a particular file, then the most -likely problem is that one of the modems will not transmit the XON or -XOFF characters. Several UUCP protocols require an eight bit clean -connection, which means that the modems must treat XON or XOFF as normal -data characters, not as flow control signals. This should always be -checked first. - -Other possible problems are that the modems have simply dropped their -connection, or perhaps on one side or the other the serial buffer is -overflowing and dropping characters. Another possibility is that the -UUCP packages disagree about some aspect of the UUCP protocol, which is -uncommon but does happen occasionally. - -Using the information in the following sections, you should be able to -figure out what type of data your UUCP was expecting to receive. This -may give some indication as to exactly what the problem is. It is -difficult to be more specific, since there are many possiblities. - -@format ------------------------------- - -From: UUCP Grades -Subject: UUCP Grades -@end format -@end ifset - -@node UUCP Grades, UUCP Lock Files, UUCP Protocol Sources, Protocols -@section UUCP Grades -@cindex grades implementation - -Modern UUCP packages support a priority grade for each command. The -grades generally range from @kbd{A} (the highest) to @kbd{Z} followed by -@kbd{a} to @kbd{z}. Some UUCP packages (including Taylor UUCP) also -support @kbd{0} to @kbd{9} before @kbd{A}. Some UUCP packages may -permit any ASCII character as a grade. - -On Unix, these grades are encoded in the name of the command file -created by @code{uucp} or @code{uux}. A command file name generally has -the form @file{C.nnnngssss} where @samp{nnnn} is the remote system name -for which the command is queued, @samp{g} is a single character grade, -and @samp{ssss} is a four character sequence number. For example, a -command file created for the system @samp{airs} at grade @samp{Z} might -be named @file{C.airsZ2551}. - -The remote system name will be truncated to seven characters, to -ensure that the command file name will fit in the 14 character file -name limit of the traditional Unix file system. UUCP packages which -have no other means of distinguishing which command files are intended -for which systems thus require all systems they connect to to have -names that are unique in the first seven characters. Some UUCP -packages use a variant of this format which truncates the system name -to six characters. HDB and Taylor UUCP use a different spool -directory format, which allows up to fourteen characters to be used -for each system name. - -The sequence number in the command file name may be a decimal integer, -or it may be a hexadecimal integer, or it may contain any alphanumeric -character. Different UUCP packages are different. -@ifclear faq -Taylor UUCP uses any alphanumeric character. -@end ifclear - -UUPlus Utilities (as FSUUCP, a shareware DOS based UUCP and news -package) uses up to 8 characters for file names in the spool (this is a -DOS file system limitation; actually, with the extension, 11 characters -are available, but FSUUCP reserves that for future use). FSUUCP -defaults mail to grade @samp{D}, and news to grade @samp{N}, except that -when the grade of incoming mail can be determined, that grade is -preserved if the mail is forwarded to another system. The default grades -may be changed by editing the @file{LIB/MAILRC} file for mail, or the -@file{UUPLUS.CFG} file for news. - -UUPC/extended for DOS, OS/2 and Windows NT handles mail at grade -@samp{C}, news at grade @samp{d}, and file transfers at grade @samp{n}. -The UUPC/extended @code{UUCP} and @code{RMAIL} commands accept grades to -override the default, the others do not. - -I do not know how command grades are handled in other non-Unix UUCP -packages. - -Modern UUCP packages allow you to restrict file transfer by grade -depending on the time of day. Typically this is done with a line in -the @file{Systems} (or @file{L.sys}) file like this: -@example - airs Any/Z,Any2305-0855 ... -@end example -This allows grades @samp{Z} and above to be transferred at any time. -Lower grades may only be transferred at night. I believe that this -grade restriction applies to local commands as well as to remote -commands, but I am not sure. It may only apply if the UUCP package -places the call, not if it is called by the remote system. - -Taylor UUCP can use the @code{timegrade} and @code{call-timegrade} -commands to achieve the same effect. -@ifclear faq -@xref{When to Call}. -@end ifclear -It supports the above format when reading @file{Systems} or -@file{L.sys}. - -UUPC/extended provides the @code{symmetricgrades} option to announce the -current grade in effect when calling the remote system. - -UUPlus allows specification of the highest grade accepted on a per-call -basis with the @samp{-g} option in @code{UUCICO}. - -This sort of grade restriction is most useful if you know what grades -are being used at the remote site. The default grades used depend on -the UUCP package. Generally @code{uucp} and @code{uux} have different -defaults. A particular grade can be specified with the @samp{-g} option -to @code{uucp} or @code{uux}. For example, to request execution of -@samp{rnews} on @samp{airs} with grade @samp{d}, you might use something -like -@example - uux -gd - airs!rnews < article -@end example - -Uunet queues up mail at grade @samp{C}, but increases the grade based on -the size. News is queued at grade @samp{d}, and file transfers at grade -@samp{n}. The example above would allow mail (below some large size) to -be received at any time, but would only permit news to be transferred at -night. - -@ifset faq -@format ------------------------------- - -From: UUCP Lock Files -Subject: UUCP Lock Files -@end format -@end ifset - -@node UUCP Lock Files, Execution File Format, UUCP Grades, Protocols -@section UUCP Lock Files -@cindex lock files - -This discussion applies only to Unix. I have no idea how UUCP locks -ports on other systems. - -UUCP creates files to lock serial ports and systems. On most, if not -all, systems, these same lock files are also used by @code{cu} to -coordinate access to serial ports. On some systems @code{getty} also -uses these lock files, often under the name @code{uugetty}. - -The lock file normally contains the process ID of the locking process. -This makes it easy to determine whether a lock is still valid. The -algorithm is to create a temporary file and then link it to the name -that must be locked. If the link fails because a file with that name -already exists, the existing file is read to get the process ID. If the -process still exists, the lock attempt fails. Otherwise the lock file -is deleted and the locking algorithm is retried. - -Older UUCP packages put the lock files in the main UUCP spool directory, -@file{/usr/spool/uucp}. HDB UUCP generally puts the lock files in a -directory of their own, usually @file{/usr/spool/locks} or -@file{/etc/locks}. - -The original UUCP lock file format encodes the process ID as a four byte -binary number. The order of the bytes is host-dependent. HDB UUCP -stores the process ID as a ten byte ASCII decimal number, with a -trailing newline. For example, if process 1570 holds a lock file, it -would contain the eleven characters space, space, space, space, space, -space, one, five, seven, zero, newline. Some versions of UUCP add a -second line indicating which program created the lock (@code{uucp}, -@code{cu}, or @code{getty/uugetty}). I have also seen a third type of -UUCP lock file which does not contain the process ID at all. - -The name of the lock file is traditionally @file{LCK..} followed by the -base name of the device. For example, to lock @file{/dev/ttyd0} the -file @file{LCK..ttyd0} would be created. On SCO Unix, the lock file -name is always forced to lower case even if the device name has upper -case letters. - -System V Release 4 UUCP names the lock file using the major and minor -device numbers rather than the device name. The file is named -@file{LK.@var{XXX}.@var{YYY}.@var{ZZZ}}, where @var{XXX}, @var{YYY} and -@var{ZZZ} are all three digit decimal numbers. @var{XXX} is the major -device number of the device holding the directory holding the device -file (e.g., @file{/dev}). @var{YYY} is the major device number of the -device file itself. @var{ZZZ} is the minor device number of the device -file itself. If @code{s} holds the result of passing the device to the -stat system call (e.g., @code{stat ("/dev/ttyd0", &s)}), the following -line of C code will print out the corresponding lock file name: -@example - printf ("LK.%03d.%03d.%03d", major (s.st_dev), - major (s.st_rdev), minor (s.st_rdev)); -@end example -The advantage of this system is that even if there are several links to -the same device, they will all use the same lock file name. - -When two or more instances of @code{uuxqt} are executing, some sort of -locking is needed to ensure that a single execution job is only started -once. I don't know how most UUCP packages deal with this. Taylor UUCP -uses a lock file for each execution job. The name of the lock file is -the same as the name of the @file{X.*} file, except that the initial -@samp{X} is changed to an @samp{L}. The lock file holds the process ID -as described above. - -@ifset faq -@format ------------------------------- - -From: Execution File Format -Subject: Execution File Format -@end format -@end ifset - -@node Execution File Format, UUCP Protocol, UUCP Lock Files, Protocols -@section Execution File Format -@cindex execution file format -@cindex @file{X.*} file format - -UUCP @file{X.*} files control program execution.

Pairs of -@samp{INITB} and @samp{INITC} packets are then similarly exchanged. -When these exchanges are completed, the protocol is considered to have -been started. - -Note that the window and packet sizes are not a negotiation.

The protocol works this way on the theory -that each system knows how much data it can accept without getting -overrun. Therefore, each system tells the other how much data to send -before waiting for an acknowledgement. - -When a UUCP package transmits a command, it sends one or more data -packets. All the data packets will normally be complete, although some -UUCP packages may send the last one as a short packet. The command -string is sent with a trailing null byte, to let the receiving package -know when the command is finished.

This permits each UUCP command -to be uniquely identified by the channel number on the originating -system, and therefore each UUCP package can associate all file data -and UUCP command responses with the appropriate command. This is a -requirement for bidirectional UUCP transfers. - -The protocol maintains a single global file position, which starts at 0. -For each incoming packet, any associated data is considered to occur at -the current file position, and the file position is incremented by the -amount of data contained. The exception is a packet of type -@samp{SPOS}, which is used to change the file position. The reason for -keeping track of the file position is described below. - -The header is as follows: - -@table @asis -@item @samp{\007} -Every packet begins with @kbd{^G}. - -@item @code{(@var{packet} << 3) + @var{locchan}} -The five bit packet number combined with the three bit local channel -number. @samp{DATA}, @samp{SPOS} and @samp{CLOSE} packets use the -packet sequence number for the @var{packet} field. @samp{NAK} packet -types use the @var{packet} field for the sequence number to be resent. -@samp{ACK} and @samp{SYNC} do not use the @var{packet} field, and -generally leave it set to 0. Packets which are not associated with a -UUCP command from the local system use a local channel number of 0. - -@item @code{(@var{ack} << 3) + @var{remchan}} -The five bit packet acknowledgement combined with the three bit remote -channel number. The packet acknowledgement is the number of the last -packet successfully received; it is used by all packet types. Packets -which are not sent in response to a UUCP command from the remote system -use a remote channel number of 0. - -@item @code{(@var{type} << 5) + (@var{caller} << 4) + @var{len1}} -The three bit packet type combined with the one bit packet direction -combined with the upper four bits of the data length. The packet -direction bit is always 1 for packets sent by the calling UUCP, and 0 -for packets sent by the called UUCP. This prevents confusion caused by -echoed packets. - -@item @var{len2} -The lower eight bits of the data length. The twelve bits of data length -permit packets ranging in size from 0 to 4095 bytes. - -@item @var{check} -The exclusive or of the second through fifth bytes of the header. This -provides an additional check that the header is valid. -@end table - -If the data length is non-zero, the packet is immediately followed by -the specified number of data bytes. The data bytes are followed by a -four byte CRC 32 checksum, with the most significant byte first. The -CRC is calculated over the contents of the data field. - -The defined packet types are as follows: - -@table @asis -@item 0 @samp{DATA} -This is a plain data packet. - -@item 1 @samp{SYNC} -@samp{SYNC} packets are exchanged when the protocol is initialized, and -are described further below. @samp{SYNC} packets do not carry sequence -numbers (that is, the @var{packet} field is ignored). - -@item 2 @samp{ACK} -This is an acknowledgement packet. Since @samp{DATA} packets also carry -packet acknowledgements, @samp{ACK} packets are only used when one side -has no data to send. @samp{ACK} packets do not carry sequence numbers. - -@item 3 @samp{NAK} -This is a negative acknowledgement. This is sent when a packet is -received incorrectly, and means that the packet number appearing in the -@var{packet} field must be resent. @samp{NAK} packets do not carry -sequence numbers (the @var{packet} field is already used). - -@item 4 @samp{SPOS} -This packet changes the file position. The packet contains four bytes -of data holding the file position, most significant byte first. The -next packet received will be considered to be at the named file -position. - -@item 5 @samp{CLOSE} -When the protocol is shut down, each side sends a @samp{CLOSE} packet. -This packet does have a sequence number, which could be used to ensure -that all packets were correctly received (this is not needed by UUCP, -however, which uses the higher level @samp{H} command with an @samp{HY} -response). -@end table - -When the protocol starts up, both systems send a @samp{SYNC} packet. -The @samp{SYNC} packet includes at least three bytes of data. The first -two bytes are the maximum packet size the remote system should send, -most significant byte first. The third byte is the window size the -remote system should use. The remote system may send packets of any -size up to the maximum. If there is a fourth byte, it is the number of -channels the remote system may use (this must be between 1 and 7, -inclusive). Additional data bytes may be defined in the future. - -The window size is the number of packets that may be sent before a -packet is acknowledged. There is no requirement that every packet be -acknowledged; any acknowledgement is considered to acknowledge all -packets through the number given. In the current implementation, if one -side has no data to send, it sends an @samp{ACK} when half the window is -received. - -Note that the @samp{NAK} packet corresponds to the unused @samp{g} -protocol @samp{SRJ} packet type, rather than to the @samp{RJ} packet -type. When a @samp{NAK} is received, only the named packet should be -resent, not any subsequent packets. - -Note that if both sides have data to send, but a packet is lost, it is -perfectly reasonable for one side to continue sending packets, all of -which will acknowledge the last packet correctly received, while the -system whose packet was lost will be unable to send a new packet because -the send window will be full. In this circumstance, neither side will -time out and one side of the communication will be effectively shut down -for a while. Therefore, any system with outstanding unacknowledged -packets should arrange to time out and resend a packet even if data is -being received. - -Commands are sent as a sequence of data packets with a non-zero local -channel number. The last data packet for a command includes a trailing -null byte (normally a command will fit in a single data packet). Files -are sent as a sequence of data packets ending with one of length zero. - -The channel numbers permit a more efficient implementation of the UUCP -file send command. Rather than send the command and then wait for the -@samp{SY} response before sending the file, the file data is sent -beginning immediately after the @samp{S} command is sent. If an -@samp{SN} response is received, the file send is aborted, and a final -data packet of length zero is sent to indicate that the channel number -may be reused. If an @samp{SY} reponse with a file position indicator -is received, the file send adjusts to the file position; this is why the -protocol maintains a global file position. - -Note that the use of channel numbers means that each UUCP system may -send commands and file data simultaneously. Moreover, each UUCP system -may send multiple files at the same time, using the channel number to -disambiguate the data. Sending a file before receiving an -acknowledgement for the previous file helps to eliminate the round trip -delays inherent in other UUCP protocols. - -@ifset faq -@format ------------------------------- - -From: UUCP @samp{j} Protocol -Subject: UUCP @samp{j} Protocol -@end format -@end ifset - -@node j Protocol, x Protocol, i Protocol, Protocols -@section UUCP @samp{j} Protocol -@cindex @samp{j} protocol -@cindex protocol @samp{j} - -The @samp{j} protocol is a variant of the @samp{i} protocol. It was -also written by Ian Lance Taylor, and first appeared in Taylor UUCP -version 1.04. - -The @samp{j} protocol is a version of the @samp{i} protocol designed for -communication links which intercept a few characters, such as XON or -XOFF. It is not efficient to use it on a link which intercepts many -characters, such as a seven bit link. The @samp{j} protocol performs no -error correction or detection; that is presumed to be the responsibility -of the @samp{i} protocol. - -When the @samp{j} protocol starts up, each system sends a printable -ASCII string indicating which characters it wants to avoid using. The -string begins with the ASCII character @kbd{^} (octal 136) and ends with -the ASCII character @kbd{~} (octal 176). After sending this string, -each system looks for the corresponding string from the remote system. -The strings are composed of escape sequences: @samp{\ooo}, where -@samp{o} is an octal digit. For example, sending the string -@samp{^\021\023~} means that the ASCII XON and XOFF characters should be -avoided. The union of the characters described in both strings (the -string which is sent and the string which is received) is the set of -characters which must be avoided in this conversation. Avoiding a -printable ASCII character (octal 040 to octal 176, inclusive) is not -permitted. - -After the exchange of characters to avoid, the normal @samp{i} protocol -start up is done, and the rest of the conversation uses the normal -@samp{i} protocol. However, each @samp{i} protocol packet is wrapped to -become a @samp{j} protocol packet. - -Each @samp{j} protocol packet consists of a seven byte header, followed -by data bytes, followed by index bytes, followed by a one byte trailer. -The packet header looks like this: - -@table @asis -@item @kbd{^} -Every packet begins with the ASCII character @kbd{^}, octal 136. - -@item @var{high} -@itemx @var{low} -These two characters give the total number of bytes in the packet. Both -@var{high} and @var{low} are printable ASCII characters. The length of -the packet is @code{(@var{high} - 040) * 0100 + (@var{low} - 040)}, -where @code{040 <= @var{high} < 0177} and @code{040 <= @var{low} < -0140}. This permits a length of 6079 bytes, but there is a further -restriction on packet size described below. - -@item @kbd{=} -The ASCII character @kbd{=}, octal 075. - -@item @var{data-high} -@itemx @var{data-low} -These two characters give the total number of data bytes in the packet. -The encoding is as described for @var{high} and @var{low}. The number -of data bytes is the size of the @samp{i} protocol packet wrapped inside -this @samp{j} protocol packet. - -@item @kbd{@@} -The ASCII character @kbd{@@}, octal 100. -@end table - -The header is followed by the number of data bytes given in -@var{data-high} and @var{data-low}. These data bytes are the @samp{i} -protocol packet which is being wrapped in the @samp{j} protocol packet. -However, each character in the @samp{i} protocol packet which the -@samp{j} protocol must avoid is transformed into a printable ASCII -character (recall that avoiding a printable ASCII character is not -permitted). Two index bytes are used for each character which must be -transformed. - -The index bytes immediately follow the data bytes. The index bytes are -created in pairs. Each pair of index bytes encodes the location of a -character in the @samp{i} protocol packet which was transformed to -become a printable ASCII character. Each pair of index bytes also -encodes the precise transformation which was performed. - -When the sender finds a character which must be avoided, it will -transform it using one or two operations. If the character is 0200 or -greater, it will subtract 0200. If the resulting character is less than -020, or is equal to 0177, it will xor by 020. The result is a printable -ASCII character. - -The zero based byte index of the character within the @samp{i} protocol -packet is determined. This index is turned into a two byte printable -ASCII index, @var{index-high} and @var{index-low}, such that the index -is @code{(@var{index-high} - 040) * 040 + (@var{index-low} - 040)}. -@var{index-low} is restricted such that @code{040 <= @var{index-low} < -0100}. @var{index-high} is not permitted to be 0176, so @code{040 <= -@var{index-high} < 0176}. @var{index-low} is then modified to encode -the transformation: - -@itemize @bullet -@item If the character transformation only had to subtract 0200, then -@var{index-low} is used as is. - -@item If the character transformation only had to xor by 020, then 040 -is added to @var{index-low}. - -@item If both operations had to be performed, then 0100 is added to -@var{index-low}. However, if the value of @var{index-low} was initially -077, then adding 0100 would result in 0177, which is not a printable -ASCII character. For that special case, @var{index-high} is set to -0176, and @var{index-low} is set to the original value of -@var{index-high}. -@end itemize - -The receiver decodes the index bytes as follows (this is the reverse of -the operations performed by the sender, presented here for additional -clarity): - -@itemize @bullet -@item The first byte in the index is @var{index-high}, and the second is -@var{index-low}. - -@item If @code{040 <= @var{index-high} < 0176}, the index refers to the -data byte at position @code{(@var{index-high} - 040) * 040 + -@var{index-low} % 040}. - -@item If @code{040 <= @var{index-low} < 0100}, then 0200 must be added -to indexed byte. - -@item If @code{0100 <= @var{index-low} < 0140}, then 020 must be xor'ed -to the indexed byte. - -@item If @code{0140 <= @var{index-low} < 0177}, then 0200 must be added -to the indexed byte, and 020 must be xor'ed to the indexed byte. - -@item If @code{@var{index-high} == 0176}, the index refers to the data -byte at position @code{(@var{index-low} - 040) * 040 + 037}. 0200 must -be added to the indexed byte, and 020 must be xor'ed to the indexed -byte. -@end itemize - -This means the largest @samp{i} protocol packet which may be wrapped -inside a @samp{j} protocol packet is @code{(0175 - 040) * 040 + (077 - -040) == 3007} bytes. - -The final character in a @samp{j} protocol packet, following the index -bytes, is the ASCII character @kbd{~} (octal 176). - -The motivation behind using an indexing scheme, rather than escape -characters, is to avoid data movement. The sender may simply add a -header and a trailer to the @samp{i} protocol packet. Once the receiver -has loaded the @samp{j} protocol packet, it may scan the index bytes, -transforming the data bytes, and then pass the data bytes directly on to -the @samp{i} protocol routine. - -@ifset faq -@format ------------------------------- - -From: UUCP @samp{x} Protocol -Subject: UUCP @samp{x} Protocol -@end format -@end ifset - -@node x Protocol, y Protocol, j Protocol, Protocols -@section UUCP @samp{x} Protocol -@cindex @samp{x} protocol -@cindex protocol @samp{x} - -The @samp{x} protocol is used in Europe (and probably elsewhere) with -machines that contain an builtin X.25 card and can send eight bit data -transparently across X.25 circuits, without interference from the X.28 -or X.29 layers.

It is designed for communication lines which -handle error correction and flow control. It requires an eight bit -clean connection. It performs error detection, but not error -correction: when an error is detected, the line is dropped. It is a -streaming protocol, like the @samp{f} protocol; there are no packet -acknowledgements, so the protocol is efficient over a half-duplex -communication line such as PEP. - -Every packet contains a six byte header: - -@table @asis -@item sequence low byte -@itemx sequence high byte -A two byte sequence number, in little endian order. The first sequence -number is 0. Since the first packet is always a sync packet (described -below) the sequence number of the first data packet is always 1.

If the high bit of the -sixteen bit field is clear, this is the number of data bytes which -follow the six byte header. If the high bit is set, there is no data, -and the length field is a type of control packet. - -@item checksum low byte -@itemx checksum high byte -A two byte checksum, in little endian order. The checksum is computed -over the data bytes. The checksum algorithm is described below. If -there are no data bytes, the checksum is sent as 0. -@end table - -When the protocol starts up, each side must send a sync packet. This is -a packet with a normal six byte header followed by data. The sequence -number of the sync packet should be 0. Currently at least four bytes of -data must be sent with the sync packet. Additional bytes should be -ignored. They are defined as follows: - -@table @asis -@item version -The version number of the protocol. Currently this must be 1. Larger -numbers should be ignored; it is the responsibility of the newer version -to accommodate the older one. - -@item packet size -The maximum data length to use divided by 256.

The data packets may be of any length greater than zero and -less than or equal to the maximum permitted packet size specified in the -initial sync packet. - -After the zero length packet ending a file transfer has been received, -the receiving system sends a @samp{YPKT_ACK} control packet.

The system dependent code is in the -@file{unix} subdirectory, and also in the file @file{sysh.unx} (also -known as @file{sysdep.h}). - -With the right configuration parameters, the system independent code -calls only ANSI C functions. Some of the less common ANSI C functions -are also provided in the @file{lib} directory. The replacement function -@code{strtol} in @file{lib/strtol.c} assumes that the characters @kbd{A} -to @kbd{F} and @kbd{a} to @kbd{f} appear in strictly sequential order. -The function @code{igradecmp} in @file{uuconf/grdcmp.c} assumes that the -upper and lower case letters appear in order. Both assumptions are true -for ASCII and EBCDIC, but neither is guaranteed by ANSI C. Disregarding -these caveats, I believe that the system independent portion of the code -is strictly conforming. - -That's not too exciting, since all the work is done in the system -dependent code. I think that this code can conform to POSIX 1003.1, -given the right compilation parameters. I'm a bit less certain about -this, though. - -The code has been used on a 16 bit segmented system with no function -prototypes, so I'm fairly certain that all casts to long and pointers -are done when necessary. - -@node Naming Conventions, Patches, System Dependence, Hacking -@section Naming Conventions - -I use a modified Hungarian naming convention for my variables and -functions. As with all naming conventions, the code is rather opaque if -you are not familiar with it, but becomes clear and easy to use with -time. - -The first character indicates the type of the variable (or function -return value). Sometimes additional characters are used. I use the -following type prefixes: - -@table @samp -@item a -array; the next character is the type of an element -@item b -byte or character -@item c -count of something -@item e -stdio FILE * -@item f -boolean -@item i -generic integer -@item l -double -@item o -file descriptor (as returned by open, creat, etc.) -@item p -generic pointer -@item q -pointer to structure -@item s -structure -@item u -void (function return values only) -@item z -character string -@end table - -A generic pointer (@code{p}) is sometimes a @code{void *}, sometimes a -function pointer in which case the prefix is pf, and sometimes a pointer -to another type, in which case the next character is the type to which -it points (pf is overloaded). - -An array of strings (@code{char *[]}) would be named @code{az} (array of -string). If this array were passed to a function, the function -parameter would be named @code{paz} (pointer to array of string). - -Note that the variable name prefixes do not necessarily indicate the -type of the variable. For example, a variable prefixed with @kbd{i} may -be int, long or short. Similarly, a variable prefixed with @kbd{b} may -be a char or an int; for example, the return value of @code{getchar} -would be caught in an int variable prefixed with @kbd{b}. - -For a non-local variable (extern or file static), the first character -after the type prefix is capitalized. - -Most static variables and functions use another letter after the type -prefix to indicate which module they come from. This is to help -distinguish different names in the debugger. For example, all static -functions in @file{protg.c}, the @samp{g} protocol source code, use a -module prefix of @samp{g}. This isn't too useful, as a number of -modules use a module prefix of @samp{s}. - -@node Patches, , Naming Conventions, Hacking -@section Patches - -I am always grateful for any patches sent in.

Always invoke @code{diff} -with the original file first and the modified file second. - -If your @code{diff} does not support @samp{-c} (or you don't have -@code{diff}), send a complete copy of the modified file (if you have -just changed a single function, you can just send the new version of the -function). In particular, please do not send @code{diff} output without -the @samp{-c} option, as it is useless. - -If you have made a number of changes, it is very convenient for me if -you send each change as a separate mail message.

Chip -Salzenberg @code{<chip@@tct.com>} has contributed many patches. -@ifinfo -Franc,ois -@end ifinfo -@iftex -@tex -Fran\c cois -@end tex -@end iftex -Pinard @code{<pinard@@iro.umontreal.ca>} tirelessly tested the code and -suggested many improvements. He also put together the initial version -of this manual. Doug Evans contributed the zmodem protocol. Marc -Boucher @code{<marc@@CAM.ORG>} contributed the code supporting the pipe -port type. Jorge Cwik @code{jorge@@laser.satlink.net} contributed the -@samp{y} protocol code. Finally, Verbus M. Counts -@code{<verbus@@westmark.com>} and Centel Federal Systems, Inc., deserve -special thanks, since they actually paid me money to port this code to -System III. - -In alphabetical order: - -@example -"Earle F.

If you would like to do -something with this package that you feel is reasonable but you feel -is prohibited by the license, contact me to see if we can work it out. - -WHAT IT IS - -This is a beta release of the uuconf library. The uuconf library -provides a set of functions which can be used to read UUCP -configuration files. V2, HDB, and Taylor UUCP configuration files are -supported. - -Also included are two programs, uuchk and uuconv. uuchk will read -configuration files and display the information it finds in a verbose -format. This can be helpful to ensure that your configuration files -are set up as you expect. uuconv can be used to convert configuration -files from one type to another. This is particularly helpful for -people installing Taylor UUCP on a existing system who want to take -advantage of the additional functionality provided by the Taylor UUCP -configuration files. - -This is strictly a beta release. The library provides all the -information needed for uuchk and uuconv, but does not yet provide -everything needed for uucp or cu. I am releasing it now to get -feedback and to provide the uuconv program to people using Taylor -UUCP. - -This may well be the only time this library is release independently. -This library will be provided with Taylor UUCP, and future releases of -the library will probably only occur as part of the complete Taylor -UUCP package. - -HOW TO USE IT - -Configure and optionally install the package as described in INSTALL. - -The functions provided by the library are described in uuconf.h. At -the moment there is no additional documentation. - -Programs which use the library should include uuconf.h, and should not -include any of the other header files. The functions listed in -uuconf.h all begin with the string "uuconf_". The internal library -functions all begin with the string "_uuconf_". The internal library -functions should not be called by a program which uses the library, as -they may change in future releases. The uuchk program is an example -of program which uses the library; uuconv is not, as it relies upon -internal data structures. - -The uuchk program takes a single optional option, -I, which may be -used to specify an alternate Taylor UUCP main configuration file. The -default configuration file is $(newconfigdir)/config ($(newconfigdir) -is defined in Makefile). For example: - uuchk - uuchk -I /usr/tmp/tstuu/Config1 - -The uuconv program requires two options: -i to specify the input type -and -o to specify the output type. Both options take a string -argument, which must be one of "v2", "hdb", or "taylor". uuconv also -takes an optional -I option, which is the same as the -I option to -uuchk. The conversion is not intended to be perfect, and the results -should be manually inspected. In particular, the dialcode file is not -converted (as the format is the same for all three configuration file -types, it may simply be copied to the appropriate new name). uuconv -will create new files in the current working directory. For example: - uuconv -i hdb -o taylor - uuconv -i taylor -I /usr/tmp/tstuu/Config1 -o v2 - -NOTES - -The initial underscore on the internal library functions is required -by the GNU standards. As ANSI C reserves external identifiers with an -initial underscore for the implementation, it is possible, though -unlikely, that this will cause problems on other implementations; no -workaround is currently provided for such problems. - -The library functions rely upon the following functions: - - fclose fopen free fseek - ftell getc isalpha isdigit - islower isspace isupper malloc - realloc rewind strchr strcmp - strcspn strlen strncmp strspn - tolower toupper - -and the following header files: - - ctype.h errno.h stdio.h - -If the following functions cannot be found by the configure script, -replacements will be used (the replacement for strerror is Unix -dependent): - - getline memcpy strcasecmp strdup - strerror strncasecmp strtol - -If the following header files are found, they will be included: - - libc.h limits.h memory.h stddef.h - stdlib.h string.h strings.h sys/types.h - -The following functions are required on Unix only: - - fcntl fileno - -The following headers are used, if found, on Unix only: - - fcntl.h sys/file.h diff --git a/gnu/libexec/uucp/libuucp/MANIFEST b/gnu/libexec/uucp/libuucp/MANIFEST deleted file mode 100644 index 909eb67..0000000 --- a/gnu/libexec/uucp/libuucp/MANIFEST +++ /dev/null @@ -1,63 +0,0 @@ -COPYING -ChangeLog -MANIFEST -Makefile.in -NEWS -README -TODO -chat.c -config.h.in -configure -configure.in -conn.c -conn.h -copy.c -cu.1 -cu.c -cu.h -getopt.h -install-sh -log.c -policy.h -prot.c -prot.h -prote.c -protf.c -protg.c -proti.c -protj.c -prott.c -proty.c -protz.c -rec.c -send.c -sysh.unx -system.h -time.c -trans.c -trans.h -tstuu.c -util.c -uuchk.c -uucico.8 -uucico.c -uuconf.h -uuconv.c -uucp.1 -uucp.c -uucp.h -uucp.texi -uudefs.h -uudir.c -uulog.c -uuname.c -uupick.c -uusched.in -uustat.1 -uustat.c -uuto.in -uux.1 -uux.c -uuxqt.8 -uuxqt.c -xcmd.c diff --git a/gnu/libexec/uucp/libuucp/Makefile b/gnu/libexec/uucp/libuucp/Makefile index 3c4c5e9..4acbd9f 100644 --- a/gnu/libexec/uucp/libuucp/Makefile +++ b/gnu/libexec/uucp/libuucp/Makefile @@ -1,14 +1,13 @@ # This is the Makefile for the libuucp subdirectory of Taylor UUCP # $FreeBSD$ -LIB= uucp -SRCS = buffer.c crc.c debug.c escape.c getopt.c getop1.c parse.c spool.c \ - status.c xfree.c xmall.c xreall.c \ - getlin.c -CFLAGS+= -I$(.CURDIR)/../common_sources - -NOMAN= noman -NOPROFILE= noprofile +LIB= uucp +SRCS= buffer.c crc.c debug.c escape.c getlin.c getopt.c getop1.c \ + parse.c spool.c status.c xfree.c xmall.c xreall.c +CFLAGS+=-I$(.CURDIR)/../common_sources + +NOMAN= noman +NOPROFILE=noprofile install: diff --git a/gnu/libexec/uucp/libuucp/bsrch.c b/gnu/libexec/uucp/libuucp/bsrch.c deleted file mode 100644 index 58b8710..0000000 --- a/gnu/libexec/uucp/libuucp/bsrch.c +++ /dev/null @@ -1,54 +0,0 @@ -/* Copyright (C) 1991 Free Software Foundation, Inc. -This file is part of the GNU C Library. - -The GNU C Library is free software; you can redistribute it and/or -modify it under the terms of the GNU Library General Public License as -published by the Free Software Foundation; either version 2 of the -License, or (at your option) any later version. - -The GNU C Library is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The first byte is HIGH, the second byte is LOW, and the - number of bytes is (HIGH - 32) * 64 + (LOW - 32), where 32 <= HIGH - < 127 and 32 <= LOW < 96 (i.e., HIGH and LOW are printable ASCII - characters). This is followed by a '=' character. The next two - bytes are the number of data bytes in the packet, using the same - encoding. This is followed by a '@' character, and then that - number of data bytes. The remaining bytes in the packet are - indices of bytes which must be transformed, followed by a trailing - '~' character. The indices are encoded in the following overly - complex format. - - Each byte index is two bytes long. The first byte in the index is - INDEX-HIGH and the second is INDEX-LOW.

Given that - * Zmodem is in the public domain, no additional copyrights have been added. - * - ***************************************************************************** - * - * It's been difficult fitting Zmodem into the UUCP world. I have been guided - * mostly by trying to plug it into Taylor UUCP. Where "the Zmodem way of doing - * things" conflicted with "the UUCP way of doing things", I have err'd on the - * side of UUCP. At the end of it all, I have achieved something that will plug - * into Taylor UUCP very easily, but some might argue that I have corrupted Z - * too much. At any rate, compatibility with sz/rz was sacrificed to achieve a - * clean UUCP protocol. Given that, I took the opportunity to start from - * scratch when defining protocol constants (EG: ZBIN). - * - * 1) I wasn't quite sure how to enhance Zmodem to handle send+receive in one - * session, so I added a 'g' protocol like initialization sequence. This - * also gets this stuff out of the way, in case we ever try to support - * full-duplex. - * - * Caller Callee - * ------ ------ - * ZINIT --> <-- ZINIT - * ZDATA (ZCRCF) --> <-- ZDATA (ZCRCF) - * ZACK --> <-- ZACK - * ZINITEND --> <-- ZINITEND - * - * ZINIT is a combination of ZRINIT and ZSINIT and is intended to exchange - * simple protocol information (flags) and the protocol version number. - * ZDATA is intended to include window size information as well as the - * "Myattn" string (although at the moment it doesn't contain anything). - * ZDATA may contain at most 1k bytes of data and is sent out as one ZCRCF - * packet. Two ack's (ZACK + ZINITEND) are needed to ensure both sides have - * received ZDATA. - * - * 2) I've hardcoded several protocol parameters, like 32 bit CRC's for data. - * Others are not supported (we don't need them). - * - * 3) ZHEX headers use 32 bit CRC's. - * - * 4) Zmodem sends the ZFILE message "in one chunk". If there are errors, the - * entire string is resent. I have continued this practice. All UUCP - * commands are sent "in one chunk". This can be changed down the road if - * necessary. - * - * 5) The ZEOF message has been replaced with a new ZCRCx value: ZCRCF. ZCRCF - * is identical to ZCRCW except that it indicates the end of the message. - * The protocol here is *not* a file transfer protocol. It is an end to end - * transport protocol (that preserves message boundaries). - * - * 6) Zmodem handles restarting a file transfer, but as best as I can tell UUCP - * does not. At least Taylor UUCP doesn't. And if UUCP does start handling - * file restart, can it be plugged into the existing Zmodem way with zero - * changes? Beats me. Therefore I have removed this part of the code. One - * can always put it back in if and when UUCP handles it. Ditto for other - * pieces of removed code: there's no point in overly complicating this code - * when supporting all the bells and whistles requires enhancements to UUCP - * itself. - * - * *** It is easier to put code back in in an upward compatible manner *** - * *** than it is to correct for misunderstood code or poorly merged *** - * *** (Zmodem vs UUCP) code. *** - * - * 7) For the character in the initial "protocol selection" sequence, I have - * chosen 'a'. I'm told 'z' is already in use for something that isn't - * Zmodem. It's entirely reasonable to believe that if Zmodem ever becomes a - * standard UUCP protocol, this won't be it (so I'll leave z/Z for them). - * Publicly, this is the 'a' protocol. Internally, it is refered to as 'z'. - * A little confusing, I know. Maybe in time I'll refer to it internally as - * 'a', or maybe in time this will be *the* 'z' protocol. - * - * 8) Since we are writing a transport protocol, which isn't supposed to know - * anything about what is being transfered or where it is coming from, the - * header data value has changed meaning.

In that - case, we want to start sending the file data immediately, to avoid - the round trip delay between flocal_send_request and - flocal_send_await_reply. To do this, flocal_send_request calls - fqueue_send rather than fqueue_receive.

It can - ignore any file position request. - - If the request is not deleted, flocal_send_await_reply must arrange - for the next string to be passed to fsend_await_confirm. - Presumably fsend_await_confirm will only be called after the entire - file has been sent. - - Just to make things even more complex, these same routines support - sending execution requests, since that is much like sending a file. - For an execution request, the bcmd character will be E rather than - S. If an execution request is being sent to a system which does - not support them, it must be sent as two S requests instead. The - second one will be the execution file, but no actual file is - created; instead the zexec and znext fields in the ssendinfo - structure are used.

It is started when -.I uucp -or -.I uux -is run (unless they are given the -.B \-r -option). It is also typically started periodically using -entries in the -.I crontab -table(s). - -When invoked with -.B \-r1, -.B \-\-master, -.B \-s, -.B \-\-system, -or -.B \-S, -the daemon will place a call to a remote system, running in master -mode. Otherwise the daemon will start in slave mode, accepting a call -from a remote system. Typically a special login name will be set up -for UUCP which automatically invokes -.I uucico -when a call is made. - -When -.I uucico -terminates, it invokes the -.I uuxqt -(8) daemon, unless the -.B \-q -or -.B \-\-nouuxqt -option is given; -.I uuxqt -(8) executes any work orders created by -.I uux -(1) on a remote system, and any work orders created locally which have -received remote files for which they were waiting. - -If a call fails, -.I uucico -will normally refuse to retry the -call until a certain (configurable) amount of time -has passed. This may be overriden by the -.B -f, -.B --force, -or -.B -S -option. - -The -.B \-l, -.B \-\-prompt, -.B \-e, -or -.B \-\-loop -options may be used to force -.I uucico -to produce its own prompts of "login: " and "Password:". When another -daemon calls in, it will see these prompts and log in as usual. The -login name and password will normally be checked against a separate -list kept specially for -.I uucico -rather than the -.I /etc/passwd -file; it is possible on some systems to direct -.I uucico -to use the -.I /etc/passwd -file. The -.B \-l -or -.B \--prompt -option will prompt once and then exit; in this mode the UUCP -administrator or the superuser may use the -.B \-u -or -.B \--login -option to force a login name, in which case -.I uucico -will not prompt for one. -The -.B \-e -or -.B \--loop -option will prompt again after the first session is over; in this mode -.I uucico -will permanently control a port. - -If -.I uucico -receives a SIGQUIT, SIGTERM or SIGPIPE signal, it will cleanly abort -any current conversation with a remote system and exit. If it -receives a SIGHUP signal it will abort any current conversation, but -will continue to place calls to (if invoked with -.B \-r1 -or -.B \-\-master) -and accept calls from (if invoked with -.B \-e -or -.B \-\-loop) -other systems. If it receives a -SIGINT signal it will finish the current conversation, but will not -place or accept any more calls. -.SH OPTIONS -The following options may be given to -.I uucico. -.TP 5 -.B \-r1, \-\-master -Start in master mode (call out to a system); implied by -.B \-s, -.B \-\-system, -or -.B \-S. -If no system is specified, call any system for which work is waiting -to be done. -.TP 5 -.B \-r0, \-\-slave -Start in slave mode. This is the default. -.TP 5 -.B \-s system, \-\-system system -Call the named system. -.TP 5 -.B \-S system -Call the named system, ignoring any required wait. This is equivalent -to -.B \-s system \-f. -.TP 5 -.B \-f, \-\-force -Ignore any required wait for any systems to be called. -.TP 5 -.B \-l, \-\-prompt -Prompt for login name and password using "login: " and "Password:". -This allows -.I uucico -to be easily run from -.I inetd -(8). The login name and password are checked against the UUCP -password file, which probably has no connection to the file -.I /etc/passwd. -The -.B \-\-login -option may be used to force a login name, in which cause -.I uucico -will only prompt for a password. -.TP 5 -.B \-p port, \-\-port port -Specify a port to call out on or to listen to. -.TP 5 -.B \-e, \-\-loop -Enter endless loop of login/password prompts and slave mode daemon -execution. The program will not stop by itself; you must use -.I kill -(1) to shut it down. -.TP 5 -.B \-w, \-\-wait -After calling out (to a particular system when -.B \-s, -.B \-\-system, -or -.B \-S -is specifed, or to all systems which have work when just -.B \-r1 -or -.B \-\-master -is specifed), begin an endless loop as with -.B \-\-loop. -.TP 5 -.B \-q, \-\-nouuxqt -Do not start the -.I uuxqt -(8) daemon when finished. -.TP 5 -.B \-c, \-\-quiet -If no calls are permitted at this time, then don't make the call, but -also do not put an error message in the log file and do not update the -system status (as reported by -.I uustat -(1)). This can be convenient for automated polling scripts, which may -want to simply attempt to call every system rather than worry about -which particular systems may be called at the moment. This option -also suppresses the log message indicating that there is no work to be -done. -.TP 5 -.B \-C, \-\-ifwork -Only call the system named by -.B \-s, -.B \-\-system -or -.B \-S -if there is work for that system. -.TP 5 -.B \-D, \-\-nodetach -Do not detach from the controlling terminal. Normally -.I uucico -detaches from the terminal before each call out to another system and -before invoking -.I uuxqt. -This option prevents this. -.TP 5 -.B \-u name, \-\-login name -Set the login name to use instead of that of the invoking user. This -option may only be used by the UUCP administrator or the superuser. -If used with -.B \-\-prompt, -this will cause -.I uucico -to prompt only for the password, not the login name. -.TP 5 -.B \-z, \-\-try-next -If a call fails after the remote system is reached, try the next -alternate rather than simply exiting. -.TP 5 -.B \-i type, \-\-stdin type -Set the type of port to use when using standard input. The only -support port type is TLI, and this is only available on machines which -support the TLI networking interface. Specifying -.B \-iTLI -causes -.I uucico -to use TLI calls to perform I/O. -.TP 5 -.B \-x type, \-X type, \-\-debug type -Turn on particular debugging types. The following types are -recognized: abnormal, chat, handshake, uucp-proto, proto, port, -config, spooldir, execute, incoming, outgoing. - -Multiple types may be given, separated by commas, and the -.B \-\-debug -option may appear multiple times. A number may also be given, which -will turn on that many types from the foregoing list; for example, -.B \-\-debug 2 -is equivalent to -.B \-\-debug abnormal,chat. - -The debugging output is sent to the debugging file, usually one of -/var/spool/uucp/Debug, /usr/spool/uucp/DEBUG, or -/usr/spool/uucp/.Admin/audit.local. -.TP 5 -.B \-I file, \-\-config file -Set configuration file to use. This option may not be available, -depending upon how -.I uucico -was compiled. -.TP 5 -.B \-v, \-\-version -Report version information and exit. -.TP 5 -.B \-\-help -Print a help message and exit. -.SH FILES -The file names may be changed at compilation time or by the -configuration file, so these are only approximations. - -.br -/etc/uucp/config - Configuration file. -.br -/etc/uucp/passwd - Default UUCP password file. -.br -/var/spool/uucp - -UUCP spool directory. -.br -/var/spool/uucp/Log - -UUCP log file. -.br -/var/spool/uucppublic - -Default UUCP public directory. -.br -/var/spool/uucp/Debug - -Debugging file. -.SH SEE ALSO -kill(1), uucp(1), uux(1), uustat(1), uuxqt(8) -.SH AUTHOR -Ian Lance Taylor -<ian@airs.com> diff --git a/gnu/libexec/uucp/uucico/uucico.c b/gnu/libexec/uucp/uucico/uucico.c deleted file mode 100644 index 63b7116..0000000 --- a/gnu/libexec/uucp/uucico/uucico.c +++ /dev/null @@ -1,3074 +0,0 @@ -/* uucico.c - This is the main UUCP communication program. - - Copyright (C) 1991, 1992, 1993, 1994, 1995 Ian Lance Taylor - - This file is part of the Taylor UUCP package. - - This program is free software; you can redistribute it and/or - modify it under the terms of the GNU General Public License as - published by the Free Software Foundation; either version 2 of the - License, or (at your option) any later version. - - This program is distributed in the hope that it will be useful, but - WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This can be useful for -administrators converting from an older UUCP package. Taylor UUCP -is able to read and use old configuration file formats, but some -new features can not be selected using the old formats. -.PP -The type of configuration file to read is specified -using the `-i' or `--input' options. The type of configuration file to -write is specified using the `-o' or `--output' options. -.PP -The supported configuration file types are `taylor', `v2', and -`hdb'. For a description of the `taylor' configuration files, see -*Note Configuration Files::. The other types of configuration files -are used by traditional UUCP packages, and are not described in this -manual. -.PP -An input configuration of type `v2' or `hdb' is read from a compiled -in directory (specified by `oldconfigdir' in `Makefile'). An input -configuration of type `taylor' is read from a compiled in directory by -default, but may be overridden with the standard `-I' or `--config' -options. -.PP -The output configuration is written to files in the directory in -which -.B uuconv -is run. -.PP -Some information in the input files may not be representable in the -desired output format, in which case -.B uuconv -will silently discard it. -The output of -.B uuconv -should be carefully checked before it is used. -The -.B uuchk(8) -program may be used for this purpose. -.PP -The `-p' or `--program' option may be used to convert specific `cu' -configuration information, rather than the default of only converting -the `uucp' configuration information. -.SH SEE ALSO -cu(1), uucp(1) -.SH AUTHOR -Ian Lance Taylor (ian@airs.com). -This Manpage based on the Taylor UUCP 1.06 Texinfo documentation. - diff --git a/gnu/libexec/uucp/uuconv/uuconv.c b/gnu/libexec/uucp/uuconv/uuconv.c deleted file mode 100644 index 701ea3d..0000000 --- a/gnu/libexec/uucp/uuconv/uuconv.c +++ /dev/null @@ -1,2106 +0,0 @@ -/* uuconv.c - Convert one type of UUCP configuration file to another. - - Copyright (C) 1991, 1992, 1993, 1994, 1995 Ian Lance Taylor - - This file is part of the Taylor UUCP package. - - This program is free software; you can redistribute it and/or - modify it under the terms of the GNU General Public License as - published by the Free Software Foundation; either version 2 of the - License, or (at your option) any later version. - - This program is distributed in the hope that it will be useful, but - WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Each -.I file -argument is either a pathname on the local machine or is of the form -.IP -system!path -.LP -which is interpreted as being on a remote system. -In the first form, the contents of the first file are copied to the -second. In the second form, each source file is copied into the -destination directory. - -A file be transferred to or from -.I system2 -via -.I system1 -by using -.IP -system1!system2!path. -.LP - -Any pathname that does not begin with / or ~ will be appended to the -current directory (unless the -.B \-W -or -.B \--noexpand -option is used); this resulting path will not necessarily exist on a -remote system. A pathname beginning with a simple ~ starts at the -UUCP public directory; a pathname beginning with ~name starts at the -home directory of the named user. The ~ is interpreted on the -appropriate system. Note that some shells will interpret a simple ~ -to the local home directory before -.I uucp -sees it; to avoid this the ~ must be quoted. - -Shell metacharacters ? * [ ] are interpreted on the appropriate -system, assuming they are quoted to prevent the shell from -interpreting them first. - -The copy does not take place immediately, but is queued up for the -.I uucico -(8) daemon; the daemon is started immediately unless the -.B \-r -or -.B \-\-nouucico -switch is given. In any case, the next time the remote system is called the -file(s) will be copied. -.SH OPTIONS -The following options may be given to -.I uucp. -.TP 5 -.B \-c, \-\-nocopy -Do not copy local source files to the spool directory. If they are -removed before being processed by the -.I uucico -(8) daemon, the copy will fail. The files must be readable by the -.I uucico -(8) daemon, and by the invoking user. -.TP 5 -.B \-C, \-\-copy -Copy local source files to the spool directory. This is the default. -.TP 5 -.B \-d, \-\-directories -Create all necessary directories when doing the copy. This is the -default. -.TP 5 -.B \-f, \-\-nodirectories -If any necessary directories do not exist for the destination path, -abort the copy. -.TP 5 -.B \-R, \-\-recursive -If any of the source file names are directories, copy their contents -recursively to the destination (which must itself be a directory). -.TP 5 -.B \-g grade, \-\-grade grade -Set the grade of the file transfer command. Jobs of a higher grade -are executed first. Grades run 0 ... 9 A ... Z a ... z from high to -low. -.TP 5 -.B \-m, \-\-mail -Report completion or failure of the file transfer by -.I mail -(1). -.TP 5 -.B \-n user, \-\-notify user -Report completion or failure of the file transfer by -.I mail -(1) to the named -user on the remote system. -.TP 5 -.B \-r, \-\-nouucico -Do not start -.I uucico -(8) daemon immediately; merely queue up the file transfer for later -execution. -.TP 5 -.B \-j, \-\-jobid -Print jobid on standard output. The job may be -later cancelled by passing the jobid to the -.B \-k -switch of -.I uustat -(1). -It is possible for some complex operations to produce more than one -jobid, in which case each will be printed on a separate line. For -example -.br -.in +0.5i -.nf -uucp sys1!~user1/file1 sys2!~user2/file2 ~user3 -.fi -.in -0.5i -will generate two separate jobs, one for the system -.I sys1 -and one for the system -.I sys2. -.TP 5 -.B \-W, \-\-noexpand -Do not prepend remote relative path names with the current directory. -.TP 5 -.B \-t, \-\-uuto -This option is used by the -.I uuto -shell script. It causes -.I uucp -to interpret the final argument as -.I system!user. -The file(s) are sent to -.I ~/receive/USER/LOCAL -on the remote system, where -.I USER -is from the final argument and -.I LOCAL -is the local UUCP -system name. Also, -.I uucp -will act as though -.I \-\-notify user -were specified. -.TP 5 -.B \-x type, \-\-debug type -Turn on particular debugging types. The following types are -recognized: abnormal, chat, handshake, uucp-proto, proto, port, -config, spooldir, execute, incoming, outgoing. Only abnormal, config, -spooldir and execute are meaningful for -.I uucp. - -Multiple types may be given, separated by commas, and the -.B \-\-debug -option may appear multiple times. A number may also be given, which -will turn on that many types from the foregoing list; for example, -.B \-\-debug 2 -is equivalent to -.B \-\-debug abnormal,chat. -.TP 5 -.B \-I file, \-\-config file -Set configuration file to use.

Queued execution requests are processed by -.I uuxqt -(8) rather than -.I uucico -(8). Queued execution requests may be waiting for some file to be -transferred from a remote system. They are created by an invocation -of -.I uux -(1). -.TP 5 -.B \-s system, \-\-system system -List all jobs queued up for the named system. These options may be -specified multiple times, in which case all jobs for all the systems -will be listed. If used with -.B \-\-list -only the systems named will be listed. -.TP 5 -.B \-S system, \-\-not-system system -List all jobs queued for systems other than the one named. These -options may be specified multiple times, in which case no jobs from -any of the specified systems will be listed. If used with -.B \-\-list -only the systems not named will be listed. These options may not be -used with -.B \-s -or -.B \-\-system. -.TP 5 -.B \-u user, \-\-user user -List all jobs queued up for the named user. These options may be -specified multiple times, in which case all jobs for all the users -will be listed. -.TP 5 -.B \-U user, \-\-not-user user -List all jobs queued up for users other than the one named. These -options may be specified multiple times, in which case no jobs from -any of the specified users will be listed. These options may not be -used with -.B \-u -or -.B \-\-user. -.TP 5 -.B \-c command, \-\-command command -List all jobs requesting the execution of the named command. If -.B command -is -.I ALL -this will list all jobs requesting the execution of some command (as -opposed to simply requesting a file transfer). These options may be -specified multiple times, in which case all jobs requesting any of the -commands will be listed. -.TP 5 -.B \-C command, \-\-not-command command -List all jobs requesting execution of some command other than the -named command, or, if -.B command -is -.I ALL, -list all jobs that simply request a file transfer (as opposed to -requesting the execution of some command). These options may be -specified multiple times, in which case no job requesting one of the -specified commands will be listed. These options may not be used with -.B \-c -or -.B \-\-command. -.TP 5 -.B \-o hours, \-\-older-than hours -List all queued jobs older than the given number of hours. If used -with -.B \-\-list -only systems whose oldest job is older than the given number of hours -will be listed. -.TP 5 -.B \-y hours, \-\-younger-than hours -List all queued jobs younger than the given number of hours. If used -with -.B \-\-list -only systems whose oldest job is younger than the given number of -hours will be listed. -.TP 5 -.B \-k jobid, \-\-kill jobid -Kill the named job. The job id is shown by the default output format, -as well as by the -.B \-j -or -.B \-\-jobid -option to -.I uucp -(1) or -.I uux -(1). A job may only be killed by the user who created the job, or by -the UUCP administrator or the superuser. The -.B \-k -or -.B \-\-kill -options may be used multiple times on the command line to kill several -jobs. -.TP 5 -.B \-r jobid, \-\-rejuvenate jobid -Rejuvenate the named job. This will mark it as having been invoked at -the current time, affecting the output of the -.B \-o, -.B \-\-older-than, -.B \-y, -or -.B \-\-younger-than -options and preserving it from any automated cleanup daemon. The job -id is shown by the default output format, as well as by the -.B \-j -or -.B \-\-jobid -options to -.I uucp -(1) or -.I uux -(1). A job may only be rejuvenated by the user who created the job, -or by the UUCP administrator or the superuser. The -.B \-r -or -.B \-\-rejuvenate -options may be used multiple times on the command line to rejuvenate -several jobs. -.TP 5 -.B \-q, \-\-list -Display the status of commands, executions and conversations for all -remote systems for which commands or executions are queued. The -.B \-s, -.B \-\-system, -.B \-S, -.B \-\-not-system, -.B \-o, -.B \-\-older-than, -.B \-y, -and -.B \-\-younger-than -options may be used to restrict the systems which are listed. Systems -for which no commands or executions are queued will never be listed. -.TP 5 -.B \-m, \-\-status -Display the status of conversations for all remote systems. -.TP 5 -.B \-p, \-\-ps -Display the status of all processes holding UUCP locks on systems or -ports. -.TP 5 -.B \-i, \-\-prompt -For each listed job, prompt whether to kill the job or not. If the -first character of the input line is -.I y -or -.I Y -the job will be killed. -.TP 5 -.B \-K, \-\-kill-all -Automatically kill each listed job. This can be useful for automatic -cleanup scripts, in conjunction with the -.B \-\-mail -and -.B \-\-notify -options. -.TP 5 -.B \-R, \-\-rejuvenate-all -Automatically rejuvenate each listed job. This may not be used with -.B \-\-kill-all. -.TP 5 -.B \-M, \-\-mail -For each listed job, send mail to the UUCP administrator. If the job -is killed (due to -.B \-\-kill-all -or -.B \-\-prompt -with an affirmative response) the mail will indicate that. A comment -specified by the -.B \-\-comment -option may be included. If the job is an execution, the initial -portion of its standard input will be included in the mail message; -the number of lines to include may be set with the -.B \-\-mail-lines -option (the default is 100). If the standard input contains null -characters, it is assumed to be a binary file and is not included. -.TP 5 -.B \-N, \-\-notify -For each listed job, send mail to the user who requested the job. The -mail is identical to that sent by the -.B \-M -or -.B \-\-mail -options. -.TP 5 -.B \-W comment, \-\-comment comment -Specify a comment to be included in mail sent with the -.B \-M, -.B \-\-mail, -.B \-N, -or -.B \-\-notify -options. -.TP 5 -.B \-B lines, \-\-mail-lines lines -When the -.B \-M, -.B \-\-mail, -.B \-N, -or -.B \-\-notify -options are used to send mail about an execution with standard input, -this option controls the number of lines of standard input to include -in the message. The default is 100. -.TP 5 -.B \-Q, \-\-no-list -Do not actually list the job, but only take any actions indicated by -the -.B \-i, -.B \-\-prompt, -.B \-K, -.B \-\-kill-all, -.B \-M, -.B \-\-mail, -.B \-N -or -.B \-\-notify -options. -.TP 5 -.B \-x type, \-\-debug type -Turn on particular debugging types. The following types are -recognized: abnormal, chat, handshake, uucp-proto, proto, port, -config, spooldir, execute, incoming, outgoing. Only abnormal, config, -spooldir and execute are meaningful for -.I uustat. - -Multiple types may be given, separated by commas, and the -.B \-\-debug -option may appear multiple times. A number may also be given, which -will turn on that many types from the foregoing list; for example, -.B \-\-debug 2 -is equivalent to -.B \-\-debug abnormal,chat. -.TP 5 -.B \-I file, \-\-config file -Set configuration file to use. This option may not be available, -depending upon how -.I uustat -was compiled. -.TP 5 -.B \-v, \-\-version -Report version information and exit. -.TP 5 -.B \-\-help -Print a help message and exit. -.SH EXAMPLES -.br -.nf -uustat --all -.fi -Display status of all jobs.

The daemon is -started automatically unless one of the -.B \-r -or -.B \-\-nouucico -options is given. - -The actual command execution is done by the -.I uuxqt -(8) daemon. - -File arguments can be gathered from remote systems to the execution -system, as can standard input. Standard output may be directed to a -file on a remote system. - -The command name may be preceded by a system name followed by an -exclamation point if it is to be executed on a remote system. An -empty system name is taken as the local system. - -Each argument that contains an exclamation point is treated as naming -a file. The system which the file is on is before the exclamation -point, and the pathname on that system follows it. An empty system -name is taken as the local system; this must be used to transfer a -file to a command being executed on a remote system. If the path is -not absolute, it will be appended to the current working directory on -the local system; the result may not be meaningful on the remote -system. A pathname may begin with ~/, in which case it is relative to -the UUCP public directory (usually /var/spool/uucppublic) on the -appropriate system. A pathname may begin with ~name/, in which case -it is relative to the home directory of the named user on the -appropriate system. - -Standard input and output may be redirected as usual; the pathnames -used may contain exclamation points to indicate that they are on -remote systems. Note that the redirection characters must be quoted -so that they are passed to -.I uux -rather than interpreted by the shell. Append redirection (>>) does -not work. - -All specified files are gathered together into a single directory -before execution of the command begins. This means that each file -must have a distinct base name. For example, -.br -.in +0.5i -.nf -uux 'sys1!diff sys2!~user1/foo sys3!~user2/foo >!foo.diff' -.fi -.in -0.5i -will fail because both files will be copied to sys1 and stored under -the name foo. - -Arguments may be quoted by parentheses to avoid interpretation of -exclamation points. This is useful when executing the -.I uucp -command on a remote system. - -A request to execute an empty command (e.g., -.I uux sys!) -will create a poll file for the specified system. -.SH OPTIONS -The following options may be given to -.I uux. -.TP 5 -.B \-, \-p, \-\-stdin -Read standard input and use it as the standard input for the command -to be executed. -.TP 5 -.B \-c, \-\-nocopy -Do not copy local files to the spool directory. This is the default. -If they are -removed before being processed by the -.I uucico -(8) daemon, the copy will fail. The files must be readable by the -.I uucico -(8) daemon, -as well as the by the invoker of -.I uux. -.TP 5 -.B \-C, \-\-copy -Copy local files to the spool directory. -.TP 5 -.B \-l, \-\-link -Link local files into the spool directory. If a file can not be -linked because it is on a different device, it will be copied unless -one of the -.B \-c -or -.B \-\-nocopy -options also appears (in other words, use of -.B \-\-link -switches the default from -.B \-\-nocopy -to -.B \-\-copy). -If the files are changed before being processed by the -.I uucico -(8) daemon, the changed versions will be used. The files must be -readable by the -.I uucico -(8) daemon, as well as by the invoker of -.I uux. -.TP 5 -.B \-g grade, \-\-grade grade -Set the grade of the file transfer command. Jobs of a higher grade -are executed first. Grades run 0 ... 9 A ... Z a ... z from high to -low. -.TP 5 -.B \-n, \-\-notification=no -Do not send mail about the status of the job, even if it fails. -.TP 5 -.B \-z, \-\-notification=error -Send mail about the status of the job if an error occurs. For many -.I uuxqt -daemons, including the Taylor UUCP -.I uuxqt, -this is the default action; for those, -.B \-\-notification=error -will have no effect. However, some -.I uuxqt -daemons will send mail if the job succeeds unless the -.B \-\-notification=error -option is used, and some other -.I uuxqt -daemons will not send mail if the job fails unless the -.B \-\-notification=error -option is used. -.TP 5 -.B \-r, \-\-nouucico -Do not start the -.I uucico -(8) daemon immediately; merely queue up the execution request for later -processing. -.TP 5 -.B \-j, \-\-jobid -Print jobids on standard output. A jobid will be generated for each -file copy operation required to perform the operation. These file -copies may be cancelled by passing the jobid to the -.B \-\-kill -switch of -.I uustat -(1), which will make the execution impossible to complete. -.TP 5 -.B \-a address, \-\-requestor address -Report job status to the specified e-mail address. -.TP 5 -.B \-x type, \-\-debug type -Turn on particular debugging types. The following types are -recognized: abnormal, chat, handshake, uucp-proto, proto, port, -config, spooldir, execute, incoming, outgoing. Only abnormal, config, -spooldir and execute are meaningful for -.I uux. - -Multiple types may be given, separated by commas, and the -.B \-\-debug -option may appear multiple times. A number may also be given, which -will turn on that many types from the foregoing list; for example, -.B \-\-debug 2 -is equivalent to -.B \-\-debug abnormal,chat. -.TP 5 -.B \-I file, \-\-config file -Set configuration file to use.
