Try using 'telnet' to connect to the socket, and see if it sends a prompt immediately on connection. If it does not, your program may need to send data out to the server first.

To expand what NetWallh said, when you telnet to port 1998 with the command below, does it send a response, or do you need to send a request in order to get a response? `telnet $SWITCH_ADDRESS 1998` `print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."`	[reply] [d/l] [select]

It seems like your while loop has no meaning. Maybe you are confused with a server socket.	[reply]

hi.. If I want to pull data from the legacy switch to our server. Is it means my server is a CLIENT and the switch is SERVER right ?. If correct, it is mean that I have to write client socket programming on my server right ? Please correct me	[reply]
