Description:
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.
