The official place to get BIND is . The official mailing lists are: bind-users@vix.com - users/admins (use *-request@* for admin mail) bind-workers@vix.com - developers The official Usenet newsgroups are: comp.protocols.tcp-ip.domains BIND is currently sponsored by: The Internet Software Consortium (send to for details.) ----- 4.9.3 BETA33 - December, 1995 - paul@vix.com Take a look around in doc/misc/ and contrib/. Reread INSTALL. Have fun. ----- 4.9.3 BETA11, BETA12 release - December, 1994 - paul@vix.com If you maintain a BSD or are otherwise running a 4.4BSD-based system and want to integrate BIND into it, check out BSD/README. Read the top of CHANGES for interesting stuff. Don't forget to purge all your secondary zone files before upgrading to this BIND if your existing one came from a vendor. The NOTIFY feature is turned off by default, but it's really cool and you should consider turning it on if you are willing to risk having it not work after the RFC process is complete (if the protocol has to change at all.) It already does not conform to the draft protocol so you should consider it "experimental" even if it happens to work fine. ----- 4.9.3 BETA10 release - August, 1994 - paul@vix.com I recommend reading this ENTIRE FILE before you attempt to build or use BIND. However, you can get started quickly by scanning down this file for "QUICK" in the right margin and just reading those sections. You can also look at the INSTALL file. You should look at doc/info/* if you have trouble building. There are at least two known bugs in this BIND: 1. if you have two authoritative zones (primary or secondary) where one is a subzone of the other, e.g., primary pa.dec.com z/pa.dec.com primary dec.com z/dec.com and you remove or comment out the subzone (pa.dec.com in our example) and SIGHUP named, the delegation and other RR's at "pa.dec.com" will be missing from your cache. to avoid this, you should "named.restart" rather than SIGHUP ("named.reload") when making changes of this kind. 2. the /HS qualifier doesn't work on "cache" directives. you will have to put your hesiod root information into your main "root.cache" file. Also, you may find that your utilities will not link with this -lresolv unless you also install lib44bsd.a and link with -lresolv -l44bsd. This is because older systems do not include inet_aton() and other functions. ----- 4.9.3 BETA6 release - June, 1994 - paul@vix.com Several private beta test releases have come and gone, and we've fixed a number of things. See CHANGES for details. There is a new Sun Shared Library update mechanism in place, and it works quite well. See shres/*. Versions of NSLOOKUP up through BIND 4.8.3's used IQUERY to ask the local server for information about the server's own name. I assume that this was done in a "what the heck, nothing uses these, how can we contrive a need?" sort of spirit. I removed this code as of BIND 4.9's NSLOOKUP and had it use the standard gethostbyaddr() mechanisms (which depend on normal queries of PTR data). Disabling INVQ and putting "options fake-iquery" in the boot file will cause IQUERY to be answered bogusly but in a way that old nslookup programs won't trip on. INVQ is disabled by default in conf/options.h. ----- 4.9.3 BETA2 release - June, 1994 - paul@vix.com News flash! BIND development is now funded by the Internet Software Consortium. Look at CHANGES to see what's new. Check out doc/misc to see some interesting papers from Purdue (and Bell Labs, if we're lucky) on DNS security that motivated many of the security-related changes present in this release. Check out shres/Makefile for SunOS4 shared library support. INVQ now defaults to "undef". See OPTIONS and conf/options.h. ALLOW_UPDATES is no longer available, and will be removed next release. You should look hard at the SENSIBLE_DOTS option and convert your serial numbers either to "sensible" ones or ones without dots (YYYYMMDD## preferred). SENSIBLE_DOTS will be the default in the next release. NCACHE and VALIDATE are _working_ now. Read the BOG! It's been updated since the previous release. If you are a vendor and are including some or all of this code in your product, please drop me a line to let me know. I field a lot of questions about BIND and it is helpful for me to know which vendor releases contain which versions of BIND. It's also helpful for me to have contacts within the engineering groups of the various vendors, since when I find a heinous bug I can let you know. ----- 4.9.2 FINAL (940221) release - February, 1994 - paul@vix.com If you look at the last entry in TODO, you'll see that there are a lot of things in the queue waiting to go in. However, I'm holding the line so that 4.9.2-FINAL can be the same as what goes out with 4.4BSD-Lite. I expect to open 4.9.3-ALPHA fairly soon, with patches comprising new work; 4.9.2-FINAL will have patches released for it only to correct bugs. The official way to get BIND 4.9.2 is: ftp gatekeeper.dec.com OUT OF DATE!!! cd pub/misc/vixie OUT OF DATE!!! binary OUT OF DATE!!! get bind-940221.tar.gz OUT OF DATE!!! or: get bind-940221.tar.Z OUT OF DATE!!! The official mailing lists are: bind-users@vix.com - users/admins (use *-request for admin mail) bind-workers@vix.com - developers The official Usenet newsgroups are: comp.protocols.tcp-ip.domains My official e-mail address is: paul@vix.com ----- 4.9.2 BETA5 (931205) release - December, 1993 - paul@vix.com no comments; see CHANGES file. ----- 4.9.2 BETA4 (931104) release - November, 1993 - paul@vix.com All reported portability problems have been fixed. All core dumps have had changes made for them and we are ready to have them tested again. As usual, I am running this in production on my own zones and I am rather confident in it. Note, again, that this is a BETA release and you should not put it up for anon-ftp or otherwise republish it in any way. ----- 4.9.2 ALPHA2 (930908) release - September, 1993 - paul@vix.com 4.9.2 has fixes for most of the bugs that smb@bellcore's white paper talked about, and CERT is going to be knocking on vendor's doors to get it shipped with as many operating systems as possible. ----- 4.9.2 ALPHA1 (930506) release - July, 1993 - Paul Vixie I don't work for DEC any more, so note the new e-mail address. The old list has been moved to ; if you intend to help hack BIND and you want to be advised of alpha-testing releases, send mail to and ask to be added to the list. Note that 4.9.1 was an interrim, nonpublished release intended to catch the porting changes needed for 4.4BSD. It never really existed separately. ----- 4.9 release - April, 1993 - Paul Vixie For information on what's new in 4.9, see OPTIONS and CHANGES. Also note that the man page for named(8) in man/named.8, and the entire Bind Operations Guide in doc/BOG/*, has been updated for 4.9. Both make excellent reading. Those of you who are thinking of adding features should first read TODO to see if someone else has already indicated an intention to work on the same thing. If your feature is significant you should ask before you hack, if for no other reason than to tell other maintainers to expect a patch soon. Note that the resolver has a number of routines that may already be present on your system. Efforts have been made to avoid generating code for them on systems where they aren't needed; don't worry about them if they're generated unneccessarily since the linker will sort things out.

The OPTIONS file here in this directory will help you figure out what to do. You should also look at the Makefile to select the proper set of definitions depending on whether you are using Ultrix, SunOS, and other 4.[23] BSD-alikes or using BSD 4.4, BSD/386, and other net2-alikes. "make links" will build a shadow source tree full of symbolic links. the default name of this tree is "./native.b", but you can override it by setting the DST variable on the "make" command line, as in: make DST=vax.b SRC=.. if your DST is not a subdir of "here", you will need to override the SRC variable's default (which is ".."), as in: make DST=/tmp/vax.b SRC=`pwd` note that the DST directory must be nonexistent at the time that you run "make links". after "make links", you can cd to the new build directory, check the settings in the Makefile, and run "make depend". if you aren't using "make links" (shame on you), just use "make depend" from "here". "make depend" may fail on your system; if so, look in the bin/ directory and find a mkdep that does in fact work for you. if you skip the "make depend" phase, or after you run it, you can do "make all" (from the build directory if you used "make links" or from "here" if you're just hacking around). you will get the following new things out of it: res/libresolv.a compat/lib/lib44bsd.a (optional) include/{netdb,resolv}.h include/arpa/{inet,nameser}.h compat/include/sys/{cdefs,bitypes}.h tools/{nstest,nsquery,dig,host} tools/nslookup/nslookup named/named named/named-xfer if you have trouble with "make all", check conf/portability.h for things that your system needs, or doesn't need, or whatever. it is preferable to add #ifdef's to conf/portability.h than to add them anywhere else. from the build directory (or "here" if you didn't use "make links"), you can try "make -n install" which will tell you what will be installed. it might actually be right; however, what you will probably have to do is copy the above files into the places you want run them from. the other files you will need are: tools/nslookup/nslookup.help named/named.restart named/named.reload resolver library notes: to install it, either put the .a file into /usr/local/lib or /usr/lib (if you use -lresolv on all the links of your networking software), or use "ar" to put all res/*.o directly into your /lib/libc.a file. either way you will want to copy the include files (including those from compat/include/sys) over to /usr/include (or /usr/local/include if you're willing to use -I/usr/local/include on all your network-software compiles). something like this: cp res/libresolv.a /usr/lib; ranlib /usr/lib/libresolv.a tar chf - include | (cd /usr/include; tar xvpf -) cp compat/include/sys/*.h /usr/include/sys installing the man pages is left as an exercise for the reader. there are just too many different versions of "man" floating around for me to be able to help you figure out what to do for the one you happen to be using. WARNING: If you were running a BIND 4.8.3 or earlier based named you should remove all cache files prior to starting named. It would generally be a good idea to remove all cache files regardless when installing a new version. The creadability code depends upon the cache files having been made with the latest named-xfer for correct operation. (special compilation-related warning about SunOS systems:) From: Tom Limoncelli To: vixie (Paul A Vixie) Date: Mon, 11 Jan 93 11:30:39 EST Sun compiler v2.0.1 hates bind4.9 code. Sun has 3 compilers: /usr/ucb/cc -- the default for SunOS 4.1.[123], dropped in Solaris 2.0. /usr/lang/cc -- the "unbundled" cc v1.0 (pretty good, but expensive), only generates code for SunOS 4.1.x. /usr/lang/cc.2.0.1 -- the latest "unbundled" cc, for when they stop shipping the bundled version altogether. This generates code for SunOS 4.1.x and Solaris 2.x. Sun's 2.0.1 C compiler (the one with the floating licenses) for SunOS 4.1.x outputs a HUGE number of warnings. They can be ignored. --------------------- (4.8.3 README -- mostly obsolete now) This directory contains all the info and sources for the Berkeley Internet Name Domain server. You should read and understand these directions before starting to install the libraries and nameserver. Some of these steps replace existing source and binary files; you should make backups of all existing files before you begin this installation. Two installation procedures are described. The first is for 4.3BSD and other similar systems that are already configured to use earlier versions of the nameserver, and which have the new version of (containing a h_addr_list field in the hostent structure). The second procedure is for 4.2BSD and derived systems. This procedure requires more decisions to be made, and may have to be varied due to system or operation constraints. The subdirectories and their contents are: bin - shell scripts used by current Berkeley makefiles man - manual pages & documentation doc - copy of Bind Operations Guide, and other documents include - include files to go in /usr/include named - name server sources res - source for C library resolver routines (and other libc additions) (may be used as separate library, resolv.a) conf/master - Sample data files tools - some test programs Here is how to install the name server on 4.3BSD: 0) cp bin/mkdep.append /usr/ucb/mkdep cp bin/manroff /usr/man/manroff 1) cp include/arpa/nameser.h /usr/include/arpa 2) cp include/*.h /usr/include 3) cp man/*.1 /usr/man/manl cp man/*.3 /usr/man/man3 cp man/*.5 /usr/man/man5 cp man/*.7 /usr/man/man7 cp man/*.8 /usr/man/man8 4) NOTE: Don't install the Makefiles on 4.3 Tahoe Release cp res/{res*.c,herror.c} /usr/src/lib/libc/net cp res/Makefile.libc.net /usr/src/lib/libc/net/Makefile cp res/strcasecmp.c /usr/src/lib/libc/gen cp res/strpbrk.c /usr/src/lib/libc/compat-sys5 cp res/named/{*.c,Makefile} /usr/src/lib/libc/net/named 5) add strcasecmp.[co] to the Makefile in /usr/src/lib/libc/gen 6) add strpbrk.[co] to the Makefile in /usr/src/lib/libc/compat-sys5 7) rebuild and install /lib/libc.a. 8) edit named/pathnames.h to correpond with your system's configuration 9) cd named; make depend; make all; make install 10) cd tools/nslookup; make nslookup; make install 11) create the master files (samples in conf/master/*) 12) edit /etc/rc.local to include: if [ -f /etc/named ]; then /etc/named; echo -n ' named' >/dev/console fi 13) recompile network client and server programs that use gethostbyname, etc. Here is how to install the name server on 4.2BSD or similar systems. First, a few notes on the choices that must be made. Rather than building libresolv.a, you may wish to integrate the resolver routines into /lib/libc.a. This is recommended to make it easy to recompile network programs once named is running. This procedure may require hand- tayloring on some systems. You will have to choose a version of mkdep from the bin directory that will work on your system: If you've modified make(1) to use .depend files as described in the current sendmail distribution, use mkdep; otherwise, if you have the 4.3BSD cc -M option, use mkdep.append; on ultrix, use mkdep.ultrix (uses cc -Em); otherwise, use mkdep.old.compiler. The mkdep script is used by "make depend" to regenerate Makefile dependency lists. You will need to chose a version of netdb.h. First, check /usr/include/netdb.h on your system. If the hostent structure has a h_addr_list entry, you can probably use your existing netdb.h or the one in include/netdb.h. If the existing netdb.h in /usr/include does not have a h_addr_list field, you will have to decide whether to update to the 4.3BSD format of the hostent structure. This is the best approach, but cannot be used unless you plan to upgrade entirely: if you use the new structure in /usr/include/resolv.h, you must recompile everything that uses the hostent structure, including the rest of the C library and all networking programs, without using any pre-existing object files. If this isn't possible or desirable, and /usr/include/netdb.h doesn't have an h_addr_list line, use include/netdb.h.4.2 instead of netdb.h. The other version of netdb.h (include/netdb.h.4.2.compat) may be used instead of include/netdb.h.4.2. This version along with a change in res/named/gethostnamadr.c.compat provide for using the new format of the hostent structure while having binary compatibility with existing libraries. On systems with Sun RPC, you will have to merge include/netdb.h or include/netdb.h.4.2 with /usr/include/netdb.h; copy the rpc-related lines into the appropriate copy of netdb.h. Alternatively, use an alternate include path when compiling the resolver library and programs that use it. 0) cp bin/{whatever} /usr/ucb/mkdep (see above) cp bin/manroff /usr/man/manroff 1) cp include/arpa/nameser.h /usr/include/arpa Also, on ultrix 2.x, if you haven't fixed the inet_addr definition in inet.h, do cp include/arpa/inet.h /usr/include/arpa 2) cp include/resolv.h /usr/include 3) cp include/netdb.h /usr/include/netdb.h OR cp include/netdb.h.4.2 /usr/include/netdb.h OR edit /usr/include/netdb.h 4) cp man/*.1 /usr/man/manl cp man/*.3 /usr/man/man3 cp man/*.5 /usr/man/man5 cp man/*.7 /usr/man/man7 cp man/*.8 /usr/man/man8 5) cd res; make depend; make libresolv.a; make install OR update the libc sources as in the 4.3BSD instructions above and use res/Makefile as a guide for integration and omit the RES=-lresolv in the next two steps OR compile the .o files in res according to Makefile, then use place those object files in /lib/libc.a (keeping a backup!) and omit the RES=-lresolv in the next two steps 6) edit named/pathnames.h to correpond with your system's configuration 7) cd named; make depend; make RES=-lresolv all; make install (if your system defines signal-catching routines to return int instead of void, use "make DEFINES=-DSIG_FN=int RES=-lresolv all") 8) edit tools/nslookup/pathnames.h to correpond with your system's configuration 9) cd tools/nslookup; make RES=-lresolv nslookup install 10) create the master files (samples in conf/master/*) 11) edit /etc/rc.local to include: if [ -f /etc/named ]; then /etc/named; echo -n ' named' >/dev/console fi 12) eventually, recompile network client and server programs that use gethostbyname, etc.
