To configure djbdns, please follow the instructions at,
http://cr.yp.to/djbdns.html
Of particular interest are,
axfrdns : http://cr.yp.to/djbdns/axfrdns-conf.html
dnscache: http://cr.yp.to/djbdns/run-cache-x-home.html
tinydns : http://cr.yp.to/djbdns/run-server.html
Portage has created users for axfrdns, dnscache, and tinydns; the
commands to configure these programs are,
1. axfrdns-conf tinydns dnslog /var/axfrdns /var/tinydns $ip
2. dnscache-conf dnscache dnslog /var/dnscache $ip
3. tinydns-conf tinydns dnslog /var/tinydns $ip
(replace $ip with the ip address on which the server will run).
If you wish to configure rbldns or walldns, you will need to create
those users yourself (although you should still use the "dnslog"
user for the logs):
4. rbldns-conf $username dnslog /var/rbldns $ip $base
5. walldns-conf $username dnslog /var/walldns $ip
