Hi,  
I copied chat server code from one or Ruby site.  
Following code is working fine But I am facing very small problem, when  
i am launching any client using telnet, then I am not able to see what I  
am typing on client console.  
example :

> telnet localhost 7666

Please help me to find out the problem.

require ‘socket’  
class ChatServer

def initialize(port) #Instantiating the server  
@sockets\_in = Array.new  
@serv\_sock = TCPServer.new("",port)  
@serv\_sock.setsockopt(Socket::SOL\_SOCKET, Socket::SO\_REUSEADDR, 1)  
puts “Chat server started on port #{port}.”  
@sockets\_in.push(@serv\_sock)  
end

def run # The runtime code for the server  
while true  
someone\_there = select(@sockets\_in, nil, nil, nil)  
if someone\_there != nil #Someone IS there, maybe wanting to  
talk?  
for socket in someone\_there[0] #Check the sockets array  
#Do we have a connect,…  
if socket == @serv\_sock then  
accept\_new  
else  
#…or did they leave,…  
if socket.eof? then #If it sends an end of file notice

- client disconnected.  
str = “Client left  
#{socket.peeraddr[2]}:#{socket.peeraddr[1]}.”  
broadcast\_string(str,socket)  
socket.close  
@sockets\_in.delete(socket)  
else  
#…or are they talking?  
str = “#{socket.peeraddr[2]}:#{socket.peeraddr[1]}  
says: #{socket.gets}”  
broadcast\_string(str,socket)  
end  
end  
end  
end  
end  
end
