A bare minimum identd server
This manual page documents briefly the nullidentd command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.
Nullidentd is intended to be a bare minimum identd server, suitable for a firewall or IP Masq/NAT gateway.
nullidentd takes only one optional argument, the username to answer with. If this is omitted, nullidentd will reply with the username “foobar”. If the username is RANDOM, a random string is generated.
nullidentd is typically invoked from inetd. The following is a typical inetd.conf example:
auth stream tcp nowait nobody /usr/sbin/nullidentd nullidentd
