Dear All. Since in our lab, we can not use socket to send information between different computers, so if there is a public ROS MASTER available, we can set it as the default ROS master, then we can use it to talk and listen with ROS node. export ROS_MASTER_URI=http://public_Master:11311

Best regards. Zhenli

This will not work. Even if you had a public roscore running, which is reachable from all your computers, you wont be able to exchange any data. You need full bi-directional connectivity between all nodes that should communicate through ros. Not just from each node to the master.

Edit: Damn, didn't see, that its a duplicate. Go with the answer given by @dornhege in your first question:
