    auss I successfully wrote my chat program and you can find the thread here:
    http://www.javaprogrammingforums.com...n-process.html
    (the last post shows the correct complete program)
    -you open the chat and it will wait on a certain port number through a serversocket
    -you open the chat on a second machine and you choose to call out, using the IP of the first machine...
    It works on one machine using the local IP and theoretical it should work on both machine, but it does not! I all the time get a time-out-error by the comp I am contacting! You know why?
