a bare minimum identd server

## NAME

nullidentd - a bare minimum identd server

## SYNOPSIS

**nullidentd** \[uid\]\

## DESCRIPTION

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.

## OPTIONS

**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.

## USAGE

**nullidentd** is typically invoked from inetd. The following is a typical inetd.conf example:\
 auth stream tcp nowait nobody /usr/sbin/nullidentd nullidentd
