      Are you trying to start the telnet server or client? If you
      want to run the server, then you have to install telnetd.

      Why port 0? The default telnet port is 23.

      The command line syntax is:
      telnet host port
      eg. telnet www.fsf.org 80
      to talk to the fsf.org webserver

      Telnet is a very bad service to run.
