Packages and Binaries:


This package is a simple PERL script to query the ident service (113/TCP) in order to determine the owner of the process listening on each TCP port of a target system.

This can help to prioritise target service during a pentest (you might want to attack services running as root first). Alternatively, the list of usernames gathered can be used for password guessing attacks on other network services.
