communication between winros and ubuntu didn't work

edit

Hi there,

I was testing the ROS communication between a windows vista laptop running winros, and a ubuntu desktop, based on instructions on this wiki page.

I run the talker.py node on one machine and listener.py node on the other. I can see the node and topic list on the listener side in command line. It seems fine. But the listener node is not picking up the message on /talker topic.

I tried the network communication tutorial on ubuntu machines and had no problems. So I suspect that the problem is on the windows side.(It works if I run talker and listener nodes both on winros).

Does anyone know what went wrong here?

Thanks
