NAME

     chatd -  a multi party chat server (or daeom).
     chat  -  a multi party chat client.

SYNOPSIS

        chatd [port]
        chat uname host port
 

DESCRIPTION
 

Chatdcreates a tcp port and accepts connections from any number of chat clients. The tcp port may be specified as a command line argument to chatd otherwise a free port is assigned and its number is announced by chatd.
 
 

Chat connects to chatd using the information provided on the command line arguments (host and port). After chat is  connected to chatd, it sends the user name (uname) of its user to chatd. Any line typed by a user of chat is sent to chatd where it is  sent to all other participants. Every line is prefixed with the sender's  uname. Any line received by chat from chatd is displayed to the user in a separate widget.  Any user can leave the conversation at any time while all other participants  may continue to chat.

Chatd never dies, even if the last participant leaves. You have to kill it with a fatal signal.
 

The SWING Interface: The design of the user interface  for this program is up
to each of you given only the  following broad guidlines:

• You should seperate the typed messages by a participant

from the recieved messages typed by  other participants.
• Provide a Quit button.
• Provide a way to list the current participants.
