Subscribe to PostsWhen building Solaris 10 servers in bulk.. That is 1 or more at a time. I usually don’t enable any sort of name resolution until later.
That’s the problem. When later rolls around, I’ve forgotten that I hadn’t enabled anything.
This would be fine and dandy if nslookup or host would let me know that my /etc/nsswitch.conf is only looking at files. It ignores that and goes strictly with what is in /etc/resolv.conf seemingly. So if that’s broke or incorrect it will, at least, tell you that.
Anyway, the system I have come up with to quickly check if nsswitch.conf is setup for DNS is to ssh to a know hostname. If this fails, it usually means you need to copy nsswitch.dns over nsswitch.conf.
Another gotcha that gets me.
