Was looking for a kwlug logo but didn't find any with text - so cut out
the logo and words from mud.jpg (from the tar download available on the
resources page: http://kwlug.org/node/404 ). Here is the result(s).

2. Telnet
Published Blog entry by Raul Suarez

I'll start this series with the simplest and oldest command.
Remember, it is not safe to expose telnet to the internet.

To install on the server (Debian/Ubuntu)
 sudo aptitude install telnetd
To start/stop under Debian 
Under Debian, the telnet daemon is started by inetd when the port is
accessed. This is controlled by the inetd.conf file. If the telnet line
is commented out, telnet will not start, otherwise it will start.
After modifying the inetd.conf file you must restart inetd for the
changes to take effect.
Comment or uncomment the telnet line
sudo nano /etc/inetd.conf 
Restart inetd
 sudo /etc/init.d/openbsd-inetd restart
To start/stop under RedHat
chkconfig telnet on
chkconfig telnet off
confirming that the port is open
To check that the port is open by name
netstat -l | grep -i ftp
Or faster and more specific, to check by port number
netstat -ln | grep 23
Connecting from the client
Once the server has started, you can connect from the client
telnet [server address]
For example:
telnet 192.168.1.105
Ending the session
To close the session
exit
