Prerequisites +---------------- + +You will need working installations of Zlib and OpenSSL. + +Zlib: +http://www.gzip.org/zlib/ + +OpenSSL 0.9.6 or greater: +http://www.openssl.org/ + +(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1 +Blowfish included) do not work correctly.) + +RPMs of OpenSSL are available at http://violet.ibs.com.au/openssh/files/support. +For Red Hat Linux 6.2, they have been released as errata. RHL7 includes +these. + +OpenSSH can utilise Pluggable Authentication Modules (PAM) if your system +supports it. PAM is standard on Redhat and Debian Linux, Solaris and +HP-UX 11. + +NB. If you operating system supports /dev/random, you should configure +OpenSSL to use it. OpenSSH relies on OpenSSL's direct support of +/dev/random. If you don't you will have to rely on ssh-rand-helper, which +is inferior to a good kernel-based solution. + +PAM: +http://www.kernel.org/pub/linux/libs/pam/ + +If you wish to build the GNOME passphrase requester, you will need the GNOME +libraries and headers. + +GNOME: +http://www.gnome.org/ + +Alternatively, Jim Knoble <jmknoble@jmknoble.cx> has written an excellent X11 +passphrase requester. This is maintained separately at: + +http://www.ntrnet.net/~jmknoble/software/x11-ssh-askpass/index.html + +PRNGD: + +If your system lacks Kernel based random collection, the use of Lutz +Jaenicke's PRNGd is recommended. + +http://www.aet.tu-cottbus.de/personen/jaenicke/postfix_tls/prngd.html + +EGD: + +The Entropy Gathering Daemon (EGD) is supported if you have a system which +lacks /dev/random and don't want to use OpenSSH's internal entropy collection. + +http://www.lothar.com/tech/crypto/ + +S/Key Libraries: +http://www.sparc.spb.su/solaris/skey/ + +If you wish to use --with-skey then you will need the above library +installed. No other current S/Key library is currently known to be +supported. + +2. Building / Installation +-------------------------- + +To install OpenSSH with default options: + +./configure +make +make install + +This will install the OpenSSH binaries in /usr/local/bin, configuration files +in /usr/local/etc, the server in /usr/local/sbin, etc. To specify a different +installation prefix, use the --prefix option to configure: + +./configure --prefix=/opt +make +make install + +Will install OpenSSH in /opt/{bin,etc,lib,sbin}. You can also override +specific paths, for example: + +./configure --prefix=/opt --sysconfdir=/etc/ssh +make +make install + +This will install the binaries in /opt/{bin,lib,sbin}, but will place the +configuration files in /etc/ssh. + +If you are using PAM, you may need to manually install a PAM control +file as "/etc/pam.d/sshd" (or wherever your system prefers to keep +them). Note that the service name used to start PAM is __progname, +which is the basename of the path of your sshd (e.g., the service name +for /usr/sbin/osshd will be osshd). If you have renamed your sshd +executable, your PAM configuration may need to be modified. + +A generic PAM configuration is included as "contrib/sshd.pam.generic", +you may need to edit it before using it on your system. If you are +using a recent version of Red Hat Linux, the config file in +contrib/redhat/sshd.pam should be more useful. Failure to install a +valid PAM file may result in an inability to use password +authentication. On HP-UX 11 and Solaris, the standard /etc/pam.conf +configuration will work with sshd (sshd will match the other service +name). + +There are a few other options to the configure script: + +--with-rsh=PATH allows you to specify the path to your rsh program. +Normally ./configure will search the current $PATH for 'rsh'. You +may need to specify this option if rsh is not in your path or has a +different name. + +--with-pam enables PAM support. + +--enable-gnome-askpass will build the GNOME passphrase dialog. You +need a working installation of GNOME, including the development +headers, for this to work. + +--with-prngd-socket=/some/file allows you to enable EGD or PRNGD +support and to specify a PRNGd socket. Use this if your Unix lacks +/dev/random and you don't want to use OpenSSH's builtin entropy +collection support. + +--with-prngd-port=portnum allows you to enable EGD or PRNGD support +and to specify a EGD localhost TCP port. Use this if your Unix lacks +/dev/random and you don't want to use OpenSSH's builtin entropy +collection support. + +--with-lastlog=FILE will specify the location of the lastlog file. +./configure searches a few locations for lastlog, but may not find +it if lastlog is installed in a different place. + +--without-lastlog will disable lastlog support entirely. + +--with-sia, --without-sia will enable or disable OSF1's Security +Integration Architecture. The default for OSF1 machines is enable. + +--with-kerberos4=PATH will enable Kerberos IV support. You will need +to have the Kerberos libraries and header files installed for this +to work. Use the optional PATH argument to specify the root of your +Kerberos installation. + +--with-afs=PATH will enable AFS support. You will need to have the +Kerberos IV and the AFS libraries and header files installed for this +to work. Use the optional PATH argument to specify the root of your +AFS installation. AFS requires Kerberos support to be enabled. + +--with-skey=PATH will enable S/Key one time password support. You will +need the S/Key libraries and header files installed for this to work. + +--with-tcp-wrappers will enable TCP Wrappers (/etc/hosts.allow|deny) +support. You will need libwrap.a and tcpd.h installed. + +--with-md5-passwords will enable the use of MD5 passwords. Enable this +if your operating system uses MD5 passwords without using PAM. + +--with-utmpx enables utmpx support. utmpx support is automatic for +some platforms. + +--without-shadow disables shadow password support. + +--with-ipaddr-display forces the use of a numeric IP address in the +$DISPLAY environment variable. Some broken systems need this. + +--with-default-path=PATH allows you to specify a default $PATH for sessions +started by sshd. This replaces the standard path entirely. + +--with-pid-dir=PATH specifies the directory in which the ssh.pid file is +created. + +--with-xauth=PATH specifies the location of the xauth binary + +--with-ipv4-default instructs OpenSSH to use IPv4 by default for new +connections. Normally OpenSSH will try attempt to lookup both IPv6 and +IPv4 addresses. On Linux/glibc-2.1.2 this causes long delays in name +resolution. If this option is specified, you can still attempt to +connect to IPv6 addresses using the command line option '-6'. + +--with-ssl-dir=DIR allows you to specify where your OpenSSL libraries +are installed. + +--with-4in6 Check for IPv4 in IPv6 mapped addresses and convert them to +real (AF_INET) IPv4 addresses. Works around some quirks on Linux. + +--with-opensc=DIR +--with-sectok=DIR allows for OpenSC or sectok smartcard libraries to +be used with OpenSSH. See 'README.smartcard' for more details. + +If you need to pass special options to the compiler or linker, you +can specify these as environment variables before running ./configure. +For example: + +CFLAGS="-O -m486" LDFLAGS="-s" LIBS="-lrubbish" LD="/usr/foo/ld" ./configure + +3. Configuration +---------------- + +The runtime configuration files are installed by in ${prefix}/etc or +whatever you specified as your --sysconfdir (/usr/local/etc by default). + +The default configuration should be instantly usable, though you should +review it to ensure that it matches your security requirements. + +To generate a host key, run "make host-key". Alternately you can do so +manually using the following commands: + + ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_key -N "" + ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N "" + ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N "" + +Replacing /etc/ssh with the correct path to the configuration directory. +(${prefix}/etc or whatever you specified with --sysconfdir during +configuration) + +If you have configured OpenSSH with EGD support, ensure that EGD is +running and has collected some Entropy. + +For more information on configuration, please refer to the manual pages +for sshd, ssh and ssh-agent. + +4.

An alternate reading of this text could +well be titled "Why I should pressure my system vendor to supply +/dev/random in their OS". + +Why is this important? OpenSSH depends on good, unpredictable numbers +for generating keys, performing digital signatures and forming +cryptographic challenges. If the random numbers that it uses are +predictable, then the strength of the whole system is compromised. + +A particularly pernicious problem arises with DSA keys (used by the +ssh2 protocol). Performing a DSA signature (which is required for +authentication), entails the use of a 160 bit random number. If an +attacker can predict this number, then they can deduce your *private* +key and impersonate you or your hosts. + +If you are using the builtin random number support (configure will +tell you if this is the case), then read this document in its entirety. +Alternately, you can use Lutz Jaenicke's PRNGd - a small daemon which +collects random numbers and makes them available by a socket. + +Please also request that your OS vendor provides a kernel-based random +number collector (/dev/random) in future versions of your operating +systems by default. + +On to the description... + +The portable OpenSSH contains random number collection support for +systems which lack a kernel entropy pool (/dev/random). + +This collector (as of 3.1 and beyond) comes as an external application +that allows the local admin to decide on how to implement entropy +collection. + +The default entropy collector operates by executing the programs listed +in ($etcdir)/ssh_prng_cmds, reading their output and adding it to the +PRNG supplied by OpenSSL (which is hash-based). It also stirs in the +output of several system calls and timings from the execution of the +programs that it runs. + +The ssh_prng_cmds file also specifies a 'rate' for each program. This +represents the number of bits of randomness per byte of output from +the specified program. + +The random number code will also read and save a seed file to +~/.ssh/prng_seed. This contents of this file are added to the random +number generator at startup. The goal here is to maintain as much +randomness between sessions as possible. + +The default entropy collection code has two main problems: + +1. It is slow. + +Executing each program in the list can take a large amount of time, +especially on slower machines. Additionally some program can take a +disproportionate time to execute. + +Tuning the default entropy collection code is difficult at this point. +It requires doing 'times ./ssh-rand-helper' and modifying the +($etcdir)/ssh_prng_cmds until you have found the issue. In the next +release we will be looking at support '-v' for verbose output to allow +easier debugging. + +The default entropy collector will timeout programs which take too long +to execute, the actual timeout used can be adjusted with the +--with-entropy-timeout configure option. OpenSSH will not try to +re-execute programs which have not been found, have had a non-zero +exit status or have timed out more than a couple of times. + +2. Estimating the real 'rate' of program outputs is non-trivial + +The shear volume of the task is problematic: there are currently +around 50 commands in the ssh_prng_cmds list, portable OpenSSH +supports at least 12 different OSs. That is already 600 sets of data +to be analysed, without taking into account the numerous differences +between versions of each OS. + +On top of this, the different commands can produce varying amounts of +usable data depending on how busy the machine is, how long it has been +up and various other factors. + +To make matters even more complex, some of the commands are reporting +largely the same data as other commands (eg. the various "ps" calls). + + +How to avoid the default entropy code? + +The best way is to read the OpenSSL documentation and recompile OpenSSL +to use prngd or egd. Some platforms (like earily solaris) have 3rd +party /dev/random devices that can be also used for this task. + +If you are forced to use ssh-rand-helper consider still downloading +prngd/egd and configure OpenSSH using --with-prngd-port=xx or +--with-prngd-socket=xx (refer to INSTALL for more information). + +$Id: WARNING.RNG,v 1.5 2002/04/14 13:16:05 djm Exp $ diff --git a/crypto/openssh/acconfig.h b/crypto/openssh/acconfig.h new file mode 100644 index 0000000..713b094 --- /dev/null +++ b/crypto/openssh/acconfig.h @@ -0,0 +1,365 @@ +/* $Id: acconfig.h,v 1.138 2002/06/12 16:57:15 mouring Exp $ */ + +#ifndef _CONFIG_H +#define _CONFIG_H + +/* Generated automatically from acconfig.h by autoheader. */ +/* Please make your changes there */ + +@TOP@ + +/* Define to a Set Process Title type if your system is */ +/* supported by bsd-setproctitle.c */ +#undef SPT_TYPE + +/* setgroups() NOOP allowed */ +#undef SETGROUPS_NOOP + +/* SCO workaround */ +#undef BROKEN_SYS_TERMIO_H + +/* Define if you have SecureWare-based protected password database */ +#undef HAVE_SECUREWARE + +/* If your header files don't define LOGIN_PROGRAM, then use this (detected) */ +/* from environment and PATH */ +#undef LOGIN_PROGRAM_FALLBACK + +/* Define if your password has a pw_class field */ +#undef HAVE_PW_CLASS_IN_PASSWD + +/* Define if your password has a pw_expire field */ +#undef HAVE_PW_EXPIRE_IN_PASSWD + +/* Define if your password has a pw_change field */ +#undef HAVE_PW_CHANGE_IN_PASSWD + +/* Define if your system uses access rights style file descriptor passing */ +#undef HAVE_ACCRIGHTS_IN_MSGHDR + +/* Define if your system uses ancillary data style file descriptor passing */ +#undef HAVE_CONTROL_IN_MSGHDR + +/* Define if you system's inet_ntoa is busted (e.g. Irix gcc issue) */ +#undef BROKEN_INET_NTOA + +/* Define if your system defines sys_errlist[] */ +#undef HAVE_SYS_ERRLIST + +/* Define if your system defines sys_nerr */ +#undef HAVE_SYS_NERR + +/* Define if your system choked on IP TOS setting */ +#undef IP_TOS_IS_BROKEN + +/* Define if you have the getuserattr function. */ +#undef HAVE_GETUSERATTR + +/* Work around problematic Linux PAM modules handling of PAM_TTY */ +#undef PAM_TTY_KLUDGE + +/* Use PIPES instead of a socketpair() */ +#undef USE_PIPES + +/* Define if your snprintf is busted */ +#undef BROKEN_SNPRINTF + +/* Define if you are on Cygwin */ +#undef HAVE_CYGWIN + +/* Define if you have a broken realpath. */ +#undef BROKEN_REALPATH + +/* Define if you are on NeXT */ +#undef HAVE_NEXT + +/* Define if you are on NEWS-OS */ +#undef HAVE_NEWS4 + +/* Define if you want to enable PAM support */ +#undef USE_PAM + +/* Define if you want to enable AIX4's authenticate function */ +#undef WITH_AIXAUTHENTICATE + +/* Define if you have/want arrays (cluster-wide session managment, not C arrays) */ +#undef WITH_IRIX_ARRAY + +/* Define if you want IRIX project management */ +#undef WITH_IRIX_PROJECT + +/* Define if you want IRIX audit trails */ +#undef WITH_IRIX_AUDIT + +/* Define if you want IRIX kernel jobs */ +#undef WITH_IRIX_JOBS + +/* Location of PRNGD/EGD random number socket */ +#undef PRNGD_SOCKET + +/* Port number of PRNGD/EGD random number socket */ +#undef PRNGD_PORT + +/* Builtin PRNG command timeout */ +#undef ENTROPY_TIMEOUT_MSEC + +/* non-privileged user for privilege separation */ +#undef SSH_PRIVSEP_USER + +/* Define if you want to install preformatted manpages.*/ +#undef MANTYPE + +/* Define if your ssl headers are included with #include <openssl/header.h> */ +#undef HAVE_OPENSSL + +/* Define if you are linking against RSAref.

Many C preprocessor symbols affect which code + gets compiled here. + + The code is designed to make it easy to modify a particular + recording method, without affecting other methods nor requiring so + many nested conditional compilation blocks as were commonplace in + the old code. + + For login recording, we try to use the local system's libraries as + these are clearly most likely to work correctly. For utmp systems + this usually means login() and logout() or setutent() etc., probably + in libutil, along with logwtmp() etc. On these systems, we fall back + to writing the files directly if we have to, though this method + requires very thorough testing so we do not corrupt local auditing + information. These files and their access methods are very system + specific indeed. + + For utmpx systems, the corresponding library functions are + setutxent() etc. To the author's knowledge, all utmpx systems have + these library functions and so no direct write is attempted. If such + a system exists and needs support, direct analogues of the [uw]tmp + code should suffice. + + Retrieving the time of last login ('lastlog') is in some ways even + more problemmatic than login recording. Some systems provide a + simple table of all users which we seek based on uid and retrieve a + relatively standard structure. Others record the same information in + a directory with a separate file, and others don't record the + information separately at all. For systems in the latter category, + we look backwards in the wtmp or wtmpx file for the last login entry + for our user. Naturally this is slower and on busy systems could + incur a significant performance penalty. + + Calling the new code + -------------------- + + In OpenSSH all login recording and retrieval is performed in + login.c. Here you'll find working examples. Also, in the logintest.c + program there are more examples. + + Internal handler calling method + ------------------------------- + + When a call is made to login_login() or login_logout(), both + routines set a struct logininfo flag defining which action (log in, + or log out) is to be taken. They both then call login_write(), which + calls whichever of the many structure-specific handlers autoconf + selects for the local system. + + The handlers themselves handle system data structure specifics. Both + struct utmp and struct utmpx have utility functions (see + construct_utmp*()) to try to make it simpler to add extra systems + that introduce new features to either structure. + + While it may seem terribly wasteful to replicate so much similar + code for each method, experience has shown that maintaining code to + write both struct utmp and utmpx in one function, whilst maintaining + support for all systems whether they have library support or not, is + a difficult and time-consuming task. + + Lastlog support proceeds similarly. Functions login_get_lastlog() + (and its OpenSSH-tuned friend login_get_lastlog_time()) call + getlast_entry(), which tries one of three methods to find the last + login time. It uses local system lastlog support if it can, + otherwise it tries wtmp or wtmpx before giving up and returning 0, + meaning "tilt". + + Maintenance + ----------- + + In many cases it's possible to tweak autoconf to select the correct + methods for a particular platform, either by improving the detection + code (best), or by presetting DISABLE_<method> or CONF_<method>_FILE + symbols for the platform. + + Use logintest to check which symbols are defined before modifying + configure.ac and loginrec.c. (You have to build logintest yourself + with 'make logintest' as it's not built by default.) + + Otherwise, patches to the specific method(s) are very helpful! + +*/ + +/** + ** TODO: + ** homegrown ttyslot() + ** test, test, test + ** + ** Platform status: + ** ---------------- + ** + ** Known good: + ** Linux (Redhat 6.2, Debian) + ** Solaris + ** HP-UX 10.20 (gcc only) + ** IRIX + ** NeXT - M68k/HPPA/Sparc (4.2/3.3) + ** + ** Testing required: Please send reports! + ** NetBSD + ** HP-UX 11 + ** AIX + ** + ** Platforms with known problems: + ** Some variants of Slackware Linux + ** + **/ + +#include "includes.h" + +#include "ssh.h" +#include "xmalloc.h" +#include "loginrec.h" +#include "log.h" +#include "atomicio.h" + +RCSID("$Id: loginrec.c,v 1.40 2002/04/23 13:09:19 djm Exp $"); + +#ifdef HAVE_UTIL_H +# include <util.h> +#endif + +#ifdef HAVE_LIBUTIL_H +# include <libutil.h> +#endif + +/** + ** prototypes for helper functions in this file + **/ + +#if HAVE_UTMP_H +void set_utmp_time(struct logininfo *li, struct utmp *ut); +void construct_utmp(struct logininfo *li, struct utmp *ut); +#endif + +#ifdef HAVE_UTMPX_H +void set_utmpx_time(struct logininfo *li, struct utmpx *ut); +void construct_utmpx(struct logininfo *li, struct utmpx *ut); +#endif + +int utmp_write_entry(struct logininfo *li); +int utmpx_write_entry(struct logininfo *li); +int wtmp_write_entry(struct logininfo *li); +int wtmpx_write_entry(struct logininfo *li); +int lastlog_write_entry(struct logininfo *li); +int syslogin_write_entry(struct logininfo *li); + +int getlast_entry(struct logininfo *li); +int lastlog_get_entry(struct logininfo *li); +int wtmp_get_entry(struct logininfo *li); +int wtmpx_get_entry(struct logininfo *li); + +/* pick the shortest string */ +#define MIN_SIZEOF(s1,s2) ( sizeof(s1) < sizeof(s2) ? sizeof(s1) : sizeof(s2) ) + +/** + ** platform-independent login functions + **/ + +/* login_login(struct logininfo *) -Record a login + * + * Call with a pointer to a struct logininfo initialised with + * login_init_entry() or login_alloc_entry() + * + * Returns: + * >0 if successful + * 0 on failure (will use OpenSSH's logging facilities for diagnostics) + */ +int +login_login (struct logininfo *li) +{ + li->type = LTYPE_LOGIN; + return login_write(li); +} + + +/* login_logout(struct logininfo *) - Record a logout + * + * Call as with login_login() + * + * Returns: + * >0 if successful + * 0 on failure (will use OpenSSH's logging facilities for diagnostics) + */ +int +login_logout(struct logininfo *li) +{ + li->type = LTYPE_LOGOUT; + return login_write(li); +} + +/* login_get_lastlog_time(int) - Retrieve the last login time + * + * Retrieve the last login time for the given uid.

The elements + * are singly linked for minimum space and pointer manipulation overhead at + * the expense of O(n) removal for arbitrary elements. New elements can be + * added to the list after an existing element or at the head of the list. + * Elements being removed from the head of the list should use the explicit + * macro for this purpose for optimum efficiency. A singly-linked list may + * only be traversed in the forward direction. Singly-linked lists are ideal + * for applications with large datasets and few or no removals or for + * implementing a LIFO queue. + * + * A list is headed by a single forward pointer (or an array of forward + * pointers for a hash table header).

New elements can be added to the list before + * or after an existing element or at the head of the list. A list + * may only be traversed in the forward direction. + * + * A simple queue is headed by a pair of pointers, one the head of the + * list and the other to the tail of the list. The elements are singly + * linked to save space, so elements can only be removed from the + * head of the list. New elements can be added to the list before or after + * an existing element, at the head of the list, or at the end of the + * list. A simple queue may only be traversed in the forward direction. + * + * A tail queue is headed by a pair of pointers, one to the head of the + * list and the other to the tail of the list. The elements are doubly + * linked so that an arbitrary element can be removed without a need to + * traverse the list. New elements can be added to the list before or + * after an existing element, at the head of the list, or at the end of + * the list. A tail queue may be traversed in either direction. + * + * A circle queue is headed by a pair of pointers, one to the head of the + * list and the other to the tail of the list. The elements are doubly + * linked so that an arbitrary element can be removed without a need to + * traverse the list. New elements can be added to the list before or after + * an existing element, at the head of the list, or at the end of the list. + * A circle queue may be traversed in either direction, but has a more + * complex end of list detection. + * + * For details on the use of these macros, see the queue(3) manual page. + */ + +/* + * Singly-linked List definitions. + */ +#define SLIST_HEAD(name, type) \ +struct name { \ + struct type *slh_first;
