HIGH-LEVEL NAME SERVER QUERY TOOLS
Version 1.4.0
03/18/1999
Copyright (c) 1993 by Paul A. Balyoz
The commands in this directory allow you to traverse DNS domain hierarchies,
list all hosts (or subdomains) within a given domain, convert host name to
IP address and vice-versa, convert a normal IP address to the "in-addr.arpa."
format and vice-versa, and more. These commands can be used manually, or
included as building blocks for higher level DNS tools. They generate output
that is easily computer parsable.
The goals of this package are:
1. To provide some high-level tools that do things which most DNS
administrators will find valuable such as: sorting by domain names,
sorting by IP addresses, generating an /etc/hosts, /etc/networks,
or /etc/netmasks files from the DNS database of an entire zone,
generating network node lists for network mapping utilities,
comparing SOA RRs from each authoritative nameserver for a zone.
2. To make it easier for people to query Internet domain name servers
using single, easy-to-use commands.
3. To provide computer-parsable output from all commands so that
higher level tools are easy to develop.
REQUIREMENTS
* BIND 4.8.3 or newer (available at http://www.isc.org/bind.html )
* DiG 2.0 or newer (distributed with BIND package)
* Perl 5 (available on Internet)
* Gnu Awk (available on Internet)
* Any form of awk named "awk"
* Bourne Shell or equivalent (i.e. sh or bash)
Also, some of the domain tools in this package require certain special
resource-records in your DNS database as described in sections 1-4 of
the RFC1101 document available on the Internet. Most of the tools will
still work without those records, but some won't (like networktbl and
netmasktbl).
DOCUMENTATION
See the file HOWTOUSE for examples of things you can do with this package.
See the file MANUAL for complete details on all the tools in this package.
Sorry, no man-pages yet; everything you need to know is in MANUAL.
See the file CHANGES for improvements since previous releases.
See the file WHY for questions and answers.
See the file BUGS for known bugs and problems.
See the file TODO for future enhancement plans.

INSTALLATION
1. Make sure you already have all the required stuff, see the
REQUIREMENTS section, above! This is important!!
2. Edit the Makefile and adjust the paths and stuff at the top.
Confused by something? See the section CONFIGURING THE
MAKEFILE, below.
3. Edit the files *.header and *.footer for your site. You can
use the macros TIMEDATE, USER and HOST wherever you want in
these files, they will expand to the current time and date,
the user's name, and the host they're run on, respectively,
when the hosttbl, networktbl, and netmasktbl tools are run.
4. Compile the C programs by typing "make".
5. Type "make -n install" to see what a "make install" would do.
6. If it looks right, type "make install" to install all the tools
and support files.
If/when you upgrade to BIND 8.x from BIND 4.x, you will also need to
clear the zone cache (see Makefile for exact location):
rm /usr/local/lib/domtools/zonecache/*
Otherwise the axfr command will generate bogus output for any zone
that it uses from the cache.
You must install these tools as shown above to use them -- you cannot
simply run them out of this directory. Certain macro replacement strings
are converted to directory paths by the Makefile during installation.
If you encounter file-not-found errors with words like "DOMBIN", "DOMLIB"
or "ZONEDIR", you haven't properly installed this package.
CONFIGURING THE MAKEFILE
Pretty standard Internet style configurations for bin directories, etc.
There are some things that may confuse you, however:
PDEST, LDEST
Physical destination tree vs. Logical destination tree.
In other words, where do you _really_ install stuff vs. where users
normally access the files at. This is useful for AFS installations,
where users and scripts commonly access a read-only path when running
programs (LDEST), but the sysadmin has to install the tools using a
different, writable directory path (PDEST). If you're confused by
this, just set them to the same thing, which should be the main tree,
such as "/usr/local" if you want tools installed in /usr/local/bin,
supporting files to go in /usr/local/lib, etc.
NETWORKSDOM
Domtools has a neat feature -- when you use the networktbl and netmasktbl
programs to build /etc/networks and /etc/netmasks style files directly
from DNS data, they can also generate comments in English above each
network entry, if you have a special branch of your DNS hierarchy that
contains TXT resource-records that describe each network! Pretty nifty.
See Makefile for further details.
ZONEDIR, ZONECACHEWANTED
The axfr tool downloads entire zone files at a time.
Axfr responds much more quickly if you cache the data in a directory
some place on the local system. It's a neat idea, but has some
drawbacks, including (currently) a world-writable directory and the
fact that no files are ever pruned out of that directory by Domtools.
If you can live with that, enable ZONECACHEWANTED and specify what
directory should be created world-writable (ZONEDIR).
TRYING IT OUT
Read the HOWTOUSE file for examples. Try them out. Say the phrase "wow"
or "interesting" at least once per tool.
For details on each domain tool, check out the large MANUAL file. If any
fail, try other tools at a lower "level" in the MANUAL first. Higher level
tools call the lower level ones to get their job done.
If you want to enable or disable the axfr tool's zone caching feature
after installation, edit "axfr" in your installed bin directory and
adjust ZONECACHEEXISTS (see comments there).

If you encounter problems or fix bugs, please let me know! Also, if you
port this package to a new platform, let me know what it took. You should
send me a general description in English of what you've done, and include
patches (diff -c oldfile newfile) so that I can include your changes in
future distributions.
This software was designed and implemented in my spare time
(guess that makes it "spareware". :-)

THOUGHT FOR THE DAY
Why type commands that operate way-down-there,
When you're thinking on a level way-up-here?
