+nullidentd (bare minimum identd server)
+
+nullidentd is intended to be a bare minimum identd server. It
+implements the auth protocol from RFC 1413. This protocol
+is used to identify active TCP connections. It depends on the
+trustworthiness of the server and as such is completely useless as
+a method of identification.
+
+Unfortunately, some applications still require that an identd
+server is available to query about incoming connections. nullidentd
+implements the absolute minimum server to allow these applications to
+function. It returns a fake response for any request.
+
+nullidentd is typically invoked from inetd. The following is a typical
+/etc/inetd.conf example:
+
+auth stream tcp nowait nobody /usr/sbin/nullidentd nullidentd

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
