Building If you do not have an ANSI/ISO C compiler, give up or get GCC. The one exception is the ULTRIX compiler, which isn't full ANSI C but it has function prototypes and BIND works around the rest. BIND 8 also wants a C library that's ANSI/ISO standard, although it can work around some common failings. If you do not have yacc, get byacc or GNU bison. If you do not have lex, get GNU flex. For information on where to get GNU software, see http://www.fsf.org/order/ftp.html. If you want to build outside the source pool, then make DST=/your/destination/here SRC=`pwd` links cd /your/destination/here If you want to use DST=/var/obj/bind, you can simply type make stdlinks Next, make sure you have no stale trash laying about make clean Then, update the Makefile dependencies: make depend Finally, make Installation To install, type make install This will copy binaries to the appropriate locations for your system, and install the BIND 8 library and header files under /usr/local/bind. The following variables can be used to change where things get installed: DESTDIR prefix used in front of all other DEST variables. The default is the empty prefix. DESTLIB libraries DESTINC include files DESTBIN ordinary binaries (e.g. dig, nslookup) DESTSBIN system binaries (e.g. named) DESTEXEC helper binaries (e.g. named-xfer) DESTHELP place to put nslookup's help file DESTETC configuration file DESTRUN PID file location These variables may be specified on the command line of the 'make' or in the Makefile.set for your port (e.g. if you use Solaris, in src/port/solaris/Makefile.set). Before doing 'make install' using either method, you must rm .settings in the top level source directory because the build system caches these variables. Using BIND 8 Library Routines Until a method to update the system's libraries is available, applications wishing to use BIND 8 library routines must include BIND 8 .h files, and must link with libbind.a. E.g. cc -I/usr/local/bind/include -c sample.c cc -o sample -L/usr/local/bind/lib sample.o -lbind The default locations for libbind.a and .h files in BIND 8.1.1 and BIND 8.1.2 are different from those used in BIND 8.1-REL. If you did a 'make install' for BIND 8.1-REL, then you should delete the files it installed. They are: /usr/local/lib/libbind.a /usr/local/include/arpa/inet.h /usr/local/include/arpa/nameser.h /usr/local/include/arpa/nameser_compat.h /usr/local/include/netdb.h /usr/local/include/resolv.h /usr/local/include/sys/bitypes.h (if it exists) /usr/local/include/sys/cdefs.h (if it exists) Operating System Notes SunOS 4.1.4 An ANSI/ISO C compiler is required; we used gcc 2.7.2.1. Solaris We've tested with Sun's compilers, yacc, and lex, and also with gcc, byacc, and flex. By default, the build will try to use gcc. If you want to use the Sun compilers, simply copy "port/solaris/Makefile.set.sun" to "port/solaris/Makefile.set". To go back to using gcc, copy "port/solaris/Makefile.set.gcc" to "port/solaris/Makefile.set". If you're using a Solaris release earlier than 2.5 and you have a large number of interfaces on your system, you many need use a script to "limit descriptors N" (where 'N' is a suitably large number) before execing "named". On Solaris 2.5 and later, the server will do this itself. Certain older versions of FreeBSD, NetBSD and BSD/OS These systems have a /bin/sh based on "ash", which doesn't handle POSIX-style quoting correctly. Using "bash" will fix the problem. Either run make with "SH=bash" on the command line, or edit src/Makefile and change "SH=sh" to "SH=bash". QNX Read src/port/qnx/README before trying to build. FD_SETSIZE The highest numbered file descriptor that the server and the resolver can utilize is determined by the FD_SETSIZE value of the system. Some systems set FD_SETSIZE much smaller than the actual number of files that can be opened. On such systems, create an "fd_setsize.h" file that sets FD_SETSIZE appropriately in the port's include directory. User and Group ID Specifying "-u" followed by a username or numeric user id on the "named" command line will cause the server to give up all privileges and become that user after the initial load of the configuation file is complete. "-g" may be used similarly to set the group id. If "-u" is specified but "-g" is not, the group used will be the given user's primary group. Here are some hints: Because the server will have no privileges after changing its user id, you must restart the server if you change the interfaces and ports that the server is listening on, or if you add an interface. If you log to files, you should create all of the log files in advance (e.g. with "touch"), and make sure they are owned by the user and group "named" will be running as. You'll have to edit "ndc" to get it to start the server with the appropriate flags. Note: this feature is still experimental. Chroot "-t" followed by a directory path on the "named" command line will cause the server to chroot() to that directory before it starts loading the configuration file. Setting up a chrooted area varies somewhat by operating system. Some experimentation may be necessary. Here are some hints: Don't forget to install named-xfer. Either don't use shared libraries when you build, or do whatever is required on your OS to allow shared libraries to be used after a chroot(). syslog() is often troublesome after chrooting. Use the "logging" statement and log to a file instead. /dev/null should be in the chroot directory hierarchy. You can usually find out the mknod parameters for a null device by looking in /dev/MAKEDEV. You'll have to edit "ndc" to get it to start the server with the appropriate flags, and to use the right pid file. Note: this feature is still experimental. Using the Server Note that /etc/named.boot is long gone. You need to make yourself an /etc/named.conf (note, that ends in "conf" rather than "boot") file. This file looks a lot like a C program or a modern gated.conf file; there are lots of {curly braces} and it takes some getting used to. You may get a lot more help from the example file (which is bin/named/named.conf) than from the documentation (see ../doc/html). You can convert your named.boot file to a named.conf file if you have Perl; see bin/named/named-bootconf.pl. All the files that used to be created in /var/tmp, e.g. named.run, will now be created in the directory specified in the options statement. If debugging is turned on using the "-d" flag on server startup, then named.run will be created in the current directory. Known Dynamic DNS Bugs If the server is master for a zone and authoritative for a child of that zone, then a dynamic update to the parent will destroy the delegation to the child when the parent zone is written to disk. This problem will be fixed in a future release. The only workaround is to not be authoritative for child zones of a dynamic zone. Slave servers do not forward update requests to the primary master correctly. This will be fixed in a future release. In the meantime, slaves will refuse dynamic updates. Shared Libraries Absolutely no support exists for editing the system's shared libraries to update the resolver. If you want to do that you probably want to look at BIND Version 4 (see http://www.isc.org/isc/) or wait a while or help out a lot. This means you probably do not want to install the library or include files into /usr/lib or /usr/include, and this kit helpfully puts everything into /usr/local/lib and /usr/local/include for that reason among others. Notes about contrib and doc The BIND 8 "doc" package includes HTML documentation as well as all the RFC's, Internet Drafts, and "man" pages we can think of. You may need to install the doc/tmac files in your nroff/troff support directory since we use the newer BSD "mandoc" system for our "man" pages. The BIND 8 "contrib" package is full of junk that you may want to take a look at. Feel free to send us more junk for future releases. Bugs Please report bugs to bind-bugs@isc.org
