I'm trying to achieve PUB/SUB over IPC. If I changed the code below so that the subscriber binds to "tcp://*:5000" and the publisher connects to "tcp://localhost:5000" it works, but I can't get it to work over IPC. What am I doing wrong?

subscriber.py

import zmq, json
def main():
    context = zmq.Context()
    subscriber = context.socket(zmq.SUB)
    subscriber.bind("ipc://test")
    subscriber.setsockopt(zmq.SUBSCRIBE, '')
    while True:
        print subscriber.recv()
if __name__ == "__main__":
    main()
publisher.py
import zmq, json, time
def main():
    context = zmq.Context()
    publisher = context.socket(zmq.PUB)
    publisher.connect("ipc://test")
    while True:
        publisher.send( "hello world" )
        time.sleep( 1 )
if __name__ == "__main__":
    main()
                Generally, the most reliable connection bind()s and the less connect()s. Usually the server is the one that binds.
