rosnode machine equivalent for ROS2?

Hi,

I am using ROS2 and I need to be able to list the nodes running on two machines. In ROS1 this can be done with rosnode machine. Is there an equivalent in ROS2?

Thanks!

ros2 node list will (ideally) list all the nodes on any machines in the domain defined by your ROS_DOMAIN_ID environment variable setting.

If it's not working, check to make sure your RMW implementation matches on all the machines. I've had some spotty results in the past perhaps due to that.
