It must be a local program trying to connect to ident.
Probably nothing to worry about. I would check which is
this program though. If that's the only message you get
you must be protected, at least packet_filtering-wise.

I think log_in_vain can be used when configuring a firewall.
Just to see quickly if your firewall works as expected and
then turn it off. Otherwise it is just going to create tons
of irrelevant log messages.
