Hi everyone!
I am facing the same problem but setting the environment variables don't seem to solve my problem. I have a VM and a SeekurJr Robot both running Ubuntu 12.04 and ROS Groovy. I also changed the hosts file in both machines.
I run the rospy_tutorials talker/listener example to test it. And the result is that when the robot is the talker and my VM is the listener I can "hear" it. The other way around doesn't work.
The robot has a M0n0wall radio and I have changed its firewall rules to allow communication on any port.
Anyone has any idea what is missing?
Thank you in Advance.
Best regards,
Aline
