Draco - DNS config files

/var/named/mk_files

This script rebuilds all of the required files from data in the /etc/hosts file.

#! /bin/sh
#
# Script to feed hosts file to h2n. First we make an options file.
cat > /tmp/h2n.tmp << EOF
-d home.spade.com
-n 172.16.167
-m 20:draco.home.spade.com
EOF

# Now we run h2n
./h2n -f /tmp/h2n.tmp

# And now we make a few additions to named.boot
cat >> named.boot << EOF
options forward-only
forwarders 204.156.128.1 204.156.128.10 204.156.128.20
EOF

/usr/sbin/named.reload

/etc/hosts

I do all changes to the zone files by changing /etc/hosts, and then running a script (h2n) to create the required files. This won't work if I were to be the primary server for more than one domain.

# For loopbacking.
127.0.0.1	localhost

172.16.167.26	versailles.home.spade.com versailles ipx	# ipx machine
172.16.167.27	dungeon.home.spade.com dungeon 			# [no smtp] win95 machine
172.16.167.28	castle.home.spade.com castle 			# [no smtp] 
172.16.167.30	draco.home.spade.com draco castle-q		# gateway

# End of hosts.

/etc/named.boot

This file is the file that tells named (the dns server daemon) where the rest of its control files are located. I have made /etc/named.boot a symbolic link to /var/named/named/boot, so that all of the control files are located in the same place.

Note that I have set 'options forward-only' and a selection of forwarders. This is what really gets diald started, whenever a request is seen for the IP address of any forign host.
