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.
