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()
most likely cause is that you are running the publisher in a different directory. Try using absolute path for the pipe location: "ipc:///tmp/test.pipe". The way you are using it now makes it relative to current working directory.
