Hello, I try to connect my Ubuntu system [a] to a virtual Ubuntu machine (VMware)[b] by network. It seems to work. I can ping and ssh from one to the other machine. Furthermore when I start a roscore on [a] I can run for example "rosrun rospy_tutorial" on machine [b] and it finds the roscore. If I start the talker on [a] I can see on [b] the topic "/chatter" and the node "/talker_3586_1356978819462".

But if I run the listener now on [b] (still with the roscore of [a]) it doesn't hear anything. I have no clue, where the problem is. Maybe someone can help me with that?

Some things that I have already tried: - Start a talker and listener only on machine [a] works. - Start a talker and listener only on machine [b] (with core of [a]) works. - Previously I had the Ubuntu system [a] also on a virtual machine and this example worked with both virtual machines [a] and [b] running in windows.

Best Jonathan

ROS relies on bidirectional communications. Make sure you work all the way through the Network Setup Guide This sounds like you have hostnames which cannot lookup fully on both machines.
