Connect to two ROS masters from one PC
Hello world,
(This is my first question so that i cannot upload image. ) I'm having a serious networking problem. I am using Ubuntu 20.04 with ROS noetic.
I have three PCs (Server PC, Client PC, and Additional PC)
- Server PC is running ROS master1, it has public IP-based internet (connect to Client PC via LTE)
- Additional PC is also running ROS master2, it has no internet (connect to Client PC via Ethernet)
- Client PC (has private LTE-based internet) wants to connect those masters simultaneously
Is that possible to connect to two ROS masters from one PC?
Thanks.

Yes, one PC can run ros nodes that connect to different ros masters. However, keep in mind that a specific ros node (linux process) is a member of exactly one ros network.

Yes, It is possible.
Just ensure that your client and server are connected using some local network and then EXPORT ROS_MASTER_URI in your client system you will see all the topics for your server.

Yes, you can use ROS_MASTER_URI to run ROS nodes connected to different roscore on other PC.
