PS: what does it do ?
Ident service uses this port. As it name says, the idea is to identify users. And it was a good idea - in the days of open Internet. Now it cannot be trusted, because many people have it configured (if they're running it at all) to send false info. And it's not a good idea to provide true info - it can be used in many ways, you don't like many of them. That's why, if you can, turn ident off (or block it using a firewall). Some apps require it (certains IRC servers, for example). If you're using such one, use the ident providing false info.
