Chat server telnet client problem

Ruby
1

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]}

    broadcast_string(str,socket)

    end
    end

    def broadcast_string(str,omit_sock) #Broadcasts the string to all
    available receiving sockets.
    @sockets_in.each do |client_sock| #each socket in the @sockets_in
    array do this:
    if client_sock != @serv_sock && client_sock != omit_sock #if
    it’s not the server socket, and not the one that sent it…
    client_sock.write(str) #…write it to the client.
    end
    end

    (#{new_sock.peeraddr[2]}:#{new_sock.peeraddr[1]}).”
