Hi, I have just installed ROS2 on two different hosts (different sub-network, different version operating system, etc), and on one of them I have: ROS_VERSION=2 ROS_DISTRO=ardent ROS_DOMAIN_ID=12345 on the other of them I have: ROS_VERSION=2 ROS_DISTRO=bouncy ROS_DOMAIN_ID=12345 I can reach the second host from the first host via ssh. Then I run ros2 run demo_nodes_cpp talker on one of them, I can see "ros2 topic list" and "ros2 node list" find out about the talker on that same host, but if I run these commands on the other host then they show nothing. I am certain that the FastRTPS RMW implementation has been built in both installations. Can someone show me an example command for discovery of remote ros2 node and topic that I can try on these two hosts? Thanks! --- [Visit Topic](https://discourse.ros.org/t/can-someone-show-me-an-example-of-remote-node-discovery-using-ros2-command/4654/1) or reply to this email to respond.
