## Hey… Im new to this network programmin and I need help with this code i copied and changed a little. this is a client/server chat… Server code: ## require “socket” PORT = 12321 server = TCPServer.new(PORT) flag=true while (session = server.accept) while flag==true print “Sending:” line=gets.chomp! session.puts line end end Client Code: require “socket” ## PORT = 12321 HOST = ARGV[0] || “localhost” flag=true session = TCPSocket.new(HOST, PORT) while flag==true line = session.gets puts "Recived:#{line} " end i dont know what i did but its sort of doing a one way communication… can someone please help me with creating two clients and making them chat 2way amongst them… please… i would really be thankfulll waiting for a reply ---

Secondly, control in this is going to be painful as it is. You probably want to thread your program so that each end can “talk” and “listen” at the same time. You could make it clunky and just switch between the two but that would be rather un-intuative. I would offer up some sample code but haven’t done any socket programming in Ruby and am currently at work I bet someone will come along with more useful info though (I offer this as something to get you going in the right direction until then). – “Hey brother Christian with your high and mighty errand, Your actions speak so loud, I can’t hear a word you’re saying.” -Greg Graffin (Bad Religion) ---

Hi HadsS, There is some example code in Peter C.s book (Beginning Ruby From Novice to Professional): [http://www.springerlink.com/content/ph5611n3q3uu0619/](http://www.springerlink.com/content/ph5611n3q3uu0619/) Not sure you’ll have access to it. I can forward you the chapter if you like. I am working on some network programming in ruby as well. Maybe we can collaborate a little. It’s not the easiest thing to grasp ☹ Vince ---

There are probably bugs but along with what you’ve already got it should be enough to teach you all the basics of Ruby network programming.

Once I wrote a TCP echo server under 30 minutes (without any previous knowledge of EM, and this includes installation of EM and reading its docs). Really nice. J. ---

HadsS, Here are a couple of pieces on threading in Ruby: [http://www.rubycentral.com/pickaxe/tut\_threads.html](http://www.rubycentral.com/pickaxe/tut_threads.html) [http://corelib.rubyonrails.org/classes/Thread.html](http://corelib.rubyonrails.org/classes/Thread.html) Hopefully this will help if you want to go in the thread direction, it is what I would do but I come from a C background.
