Subject: Ruby socket does not get reply

Hi all,

I use a TCP connection and send some data like this:

  begin
    session = "mysession"
    socket = TCPSocket.new(tcpaddress, port)
    socket.setsockopt(Socket::IPPROTO_TCP, Socket::TCP_NODELAY, 1)
    puts "sending to socket HELO " + session
    socket.write ('HELO ' + session)
    puts socket.read
    socket.close
  rescue Exception => myException
    puts "Exception rescued : #{myException}"
  end

The socket never gets a reply, however telnet does:

$ telnet some_ip port
Trying some_ip...
Connected to some_ip
Escape character is '^]'.
HELO mysession
OK


As you can see the remote server replies "OK" as expected. What's wrong?

Thanks in advanced!

PS: I have used puts and send methods also
