        Of course it is possible. Anyone can telnet to any port, on any
machine. ( more or less ).

        If you have a server process, let's say Squid, running on port
3128. You can telnet net to this port, if you give the server what is
wants, like a http request, then it will pump into your connection the
appropriate response data.

        If you don't believe me, try it! :-) Just type in the following:

                $telnet 3128

        Then type: wdsfwsadfwsafdsfd
        Press Enter.

        then you will get a html document pumped into your window.
Something along the lines of, Invalid HTTP request.

        Pretty kool, huh?
