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:
on the other of them I have:
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!
