oidentd (an identd daemon)

Oidentd is an ident daemon (rfc1413) that runs on Linux, FreeBSD, OpenBSD
and Solaris 2.x. Oidentd supports most features of pidentd plus more. Most
notably, oidentd allows users to specify the identd response that the server
will output when a successful lookup is completed. Oidentd supports IP
masqueraded connections on Linux, and is able to forward requests to hosts
that masq through the host on which oidentd runs.

This is a fork of the ojnk oidentd released in 2006
