In order to provide a simple remote endpoint that accepts your connection and sends back the received data (echo server), you could try something like this python server (or to use netcat):

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("localhost", 1234))
s.listen(1)
conn, addr = s.accept()
print 'Connected by', addr
while 1:
    data = conn.recv(1024)
    if not data: break
    conn.sendall(data)
conn.close()
