First, I would recommend using the same ROS 2 version of both sides (I see you're using Ardent and Bouncy, which is just master right now). Second, makes sure multicast UDP is working between machines. You can use `netcat` to check, see: https://serverfault.com/a/315564/186748 If that works and discovery still isn't happening, then consider filing an issue because that might be a bug. --- [Visit Topic](https://discourse.ros.org/t/can-someone-show-me-an-example-of-remote-node-discovery-using-ros2-command/4654/2) or reply to this email to respond.
