DNS resolves... but doesn't....

[Tyler Aviss]

I found it.
Apparently my recently configured system didn't like this in
"nsswitch.conf" copied from one of the other servers (though the have
the same setup):
  hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4

I worked after I changed that to:
  files mdns4_minimal dns

So it's probably a bug/misconfiguration related to MDNS, which now
seems to be a default part of nsswitch's config, though I don't
remember that being so on earlier versions of debian.


I'll probably just remove the mdns stuff entirely as it doesn't really
seem to be serving a valid purpose anymore. However, I do find it odd
that "ping"  resolved names properly, but perhaps it doesn't use
nsswitch? Maybe it's a libc bug that cropped up after I updated last.
