root@PRD /> telnet DR
Trying...
Connected to DR.
Escape character is '^]'.
Connection closed.

root@PRD /> ftp DR
Connected to KFAFH_DR.
421 Service not available, remote server has closed connection
ftp> bye

root@PRD /> ssh 10.10.10.42

LEARN ABOUT DEBIAN

in.identtestd

IN.IDENTTESTD(8)						 Library functions						  IN.IDENTTESTD(8)

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 '^]'.
	   Welcome to the IDENT server tester, version 1.9

	   (Linked with libident 0.22 Debian)

	   Connecting to Ident server at 192.168.1.1...
	   Querying for lport 1109, fport 9999....
	   Reading response data...
	   Userid response is:
	      Lport........ 1109
	      Fport........ 9999
	      Opsys........ UNIX
	      Charset...... <not specified>
	      Identifier... paul
	   Connection closed by foreign host.
