Description:
Perl module to lookup the username on the remote end of a TCP/IP connection
Net::Ident is a Perl module implementing the RFC1413 Identification Protocol, also known as "ident". . It provides both a simple interface for doing one ident lookup at a time, and an asynchronous interface to perform (possibly) many simultaneous lookups, or simply continue serving other things while the lookup is proceeding.
