pyzmq

问题 I have a Kubernetes 1.18 cluster using weave as my CNI. I have a ZMQ based pub/sub app and I am often (not always) seeing it take 2 minutes before the subscriber can receive messages from the publisher. This seems to be some sort of socket timeout uniqe to my Kubernetes environment. Here is my trivial ZMQ app example #!/bin/env python2 import zmq, sys, time, argparse, logging, datetime, threading from zmq.utils.monitor import recv_monitor_message FORMAT = '%(asctime)-15s %(message)s' logging

问题 I'm trying to use the ZeroMQ Poller() functionality with two sockets in python: import zmq # Prepare our context and sockets context = zmq.Context() receiver = context.socket(zmq.DEALER) receiver.connect("ipc:///tmp/interface-transducer") subscriber = context.socket(zmq.SUB) subscriber.bind("ipc:///tmp/fast-service") subscriber.setsockopt(zmq.SUBSCRIBE, b"10001") # Initialize poll set poller = zmq.Poller() poller.register(receiver, zmq.POLLIN) poller.register(subscriber, zmq.POLLIN) # Process

问题 I have two VMs (VirtualBOx, Ubuntu 18.04 and python-zmq) running within the same physical machine (Win10). Both machines are configured as Bridge and they can be ping successfully 192.168.1.56-192.168.1.65. I've followed this tutorial https://learning-0mq-with-pyzmq.readthedocs.io/en/latest/pyzmq/patterns/pubsub.html, however, it doesn't work. On one machine "server", the data is printed, however, at the subscriber "client", it doesn't receive anything. Have you tried this or do you know

问题 I have two VMs (VirtualBOx, Ubuntu 18.04 and python-zmq[16.0.2-2build2]) running within the same physical machine (Win10). Both machines are configured as Bridge and they can be ping successfully 192.168.1.66-192.168.1.55. I've followed this tutorial https://learning-0mq-with-pyzmq.readthedocs.io/en/latest/pyzmq/patterns/pubsub.html. It works if PUB (server) is configured as import zmq import random import sys import time port = "5557" if len(sys.argv) > 1: port = sys.argv[1] int(port)
