Sure, except you should explicitly close the connection as well at the 
end of your block rather than letting the socket object's finalizer do 
it whenever the GC gets around to calling it.  So, something like:

def send_message_and_recv_response
   server = nil
   server = TCPSocket.new @server_ip, @server_port
   server.puts "the message"
   result = server.recv
ensure
   server.close if server
end
