This is probably more of a answers.ros.org<http://answers.ros.org/> question, but I think you also need to tell computer A how to refer to itself,
e.g.   export ROS_HOSTNAME=192.168.1.100 on computer A.

Hi, I am trying to make a node on one computer(computer A) with some publishers and some services and try to read the messages and call some services with another computer(computer B).

computer A(ip is 192.168.1.100) and computer B(ip is 192.168.1.101) are connected since they can ping each other

computer A also runs a roscore since it is the master

on computer A, I set the ROS_MASTER_URI at http://localhost:11311<http://localhost:11311/>
on computer B, I set the ROS_MASTER_URI at http://192.168.1.100:11311<http://192.168.1.100:11311/> and the ROS_HOSTNAME at 192.168.1.101

and yet it doesn't work, I don't even receive the topics messages,

I am sure I am doing something wrong or maybe didn't configure my network properly.

Does someone happen to know how to solve the problem?

Thank you so much for your help.
