djbdns Installation Glitches

Installing djbdns accoring to the instructions caused an issue during
useradd Gdnscache and Gdnslog under RHEL 3. Apparently, useradd no longer
accepts upper and lower case characters.

Just replace Gdnscache and Gdnslog with their lower-case equivalents

dnscache: fatal: $IP not set

I use <tab> alot. Somehow, when I was attmpting to run dnscache-conf, I ended up running dnscache. That doesn’t work because it isn’t configured yet. Run dnscache-conf before running dnscache.
