Yeah, reverse DNS.

When you open connections to a Unix box, it typically wants to log
those somewhere, and all it has is an IP address.  So it tries to look
the address up to turn it back into a machine name ... and yours can't.

Make sure that (at least,) all your workstations appear in your
/etc/hosts file, or, if you're using "real" DNS on that machine, you
might have to actually run a DNS server -- especially if your machines
are in private IP address space (as they ought to be); most DNS servers
won't answer the reverse zone for private addresses.
