Hi,
I have req/rep working fine now. There is one deviation from the pyzmq
documentation. The documentation says that you use socket.send with a
string, but the code errors out and says use send_string instead. I
don't know if this is a version problem in the zmq I built, but I just
did pip install pyzmq.
Now I am trying to make pub/sub work and am stuck again. Here's my
trivial server:
import zmq
zc = zmq.Context()
pubsock = zc.socket(zmq.PUB)
pubsock.bind("tcp://*:12345")
for i in range(10):
msg = "topic sending message {}".format(i)
pubsock.send_string(msg)
and here's my trivial client:
import zmq
zc = zmq.Context()
subsock = zc.socket(zmq.SUB)
subsock.connect("tcp://localhost:12345")
for i in range(10):
message = subsock.recv_string()
print("{}\n".format(message))
print("got 10\n")
The client sits happily waiting for the packets that never come. When I
watch this with tcpdump, I see a bunch of packets go back and forth
during the connect but no packets come out when I do the send_string.
The same symptoms are true both on the raspberry pi and a ubuntu machine.
Any clue what is going on?
jerry
