Yeah, that's what I hear, and exactly that's in there. IIRC, I've had some success with that in the past. But it doesn't work for me today. Debian needs a domainname command like hostname. Or maybe a man page explaining what looks up what and where the string is. A file in /etc called domainname wouldn't be too much to ask, IMHO.

Mostly hostname - f. That's what I've used in a number if shell scripts, and it's always worked (on systems who've been labeled by the installer). hosts and DNS can both find the IP, given the FQDN, but hostname -f is wrong. hostname returns 'srv' like it should. But hostnane -f returns 'www.slsware.dmz' -- way wrong. I've grep'ed for that www string and haven't been able to find it.

I haven't done nsswitch.conf yet. I'll try it in the morning...
I got curious. nsswitch.conf on the old host (working hostname -f):

On the new one (bent hostname -f):

See anything interesting? I don't. Except the mention of gshadow on the bad one, and I have no idea what that makes happen. Is it possible one of those files has bad data in it? If so, what are their names and where are they?
