Title
Body
This code works great: import zmq, json, time def main(): context = zmq.Context() subscriber = context.socket(zmq.SUB) subscriber.bind("ipc://test") subscriber.setsockopt(zmq.SUBSCRIBE, '') while True: print subscriber.recv() def main(): context = zmq.Context() publisher = context.socket(zmq.PUB) publisher.connect("ipc://test") while True: publisher.send( "hello world" ) time.sleep( 1 ) But this code doesn't * work: import zmq, json, time def recv(): context = zmq.Context() subscriber = context.socket(zmq.SUB) subscriber.bind("tcp://localhost:5555") subscriber.setsockopt(zmq.SUBSCRIBE, '') while True: print subscriber.recv() def send(): context = zmq.Context() publisher = context.socket(zmq.PUB) publisher.connect("tcp://localhost:5555") while True: publisher.send( "hello world" ) time.sleep( 1 ) It raises this error: ZMQError: No such device Why, can't zeromq use localhost interfaces? Does it only work on IPC on the same machine?
