NAME
in.identtestd - a small daemon that can be used to test Ident servers
SYNOPSIS
in.identtestd
DESCRIPTION
in.identtestd is a small daemon (to be started from inetd) that does an ident lookup on you if you telnet into it. Can be used to verify
that your Ident server is working correctly.
The source code can be found in the debian libident source package, as ident-tester.c.
EXAMPLE
A typical entry in /etc/inetd.conf would be:
9999 stream tcp nowait root /usr/sbin/in.identtestd in.identtestd
With the above entry in place and active, execute "telnet hostname 9999" from either this system, or another system. It should show some-
thing like:
Trying hostname...
Connected to hostname.
Escape character is '^]'.
