identd is run from inetd.

Actually, all of them try to resolve identd and most won't allow you to
connect without it. This is to prevent spoofing for the purpose of DoS
attacks. The simple solution is to make sure the service is running,
and if you're behind a NAT layer, set up a masquerading identd (such as
midentd).
