Binary package “oidentd” in ubuntu intrepid
replacement ident daemon
An ident (rfc1413) daemon for IPv4 and IPv6.
Oidentd allows users, given the proper permission, to specify the
identd response that the server will output when a successful lookup
is completed. Oidentd also allows for pseudo-random strings
(either a prefix, such as "user," followed by a number between 0 and
99999, or 10 pseudo-random characters of the set 0-9A-Za-z) to be
returned upon the completion of a successful lookup instead of a
username or a UID.
Oidentd supports IPv4 masqueraded connections, including netfilter.
