Hello Ken, I changed the machine name for the post.. but the message does show my actual machine name (not localhost). ROS_MASTER_URI is currently set to. http://localhost:11311 The other variables are blank/not set. And it doesn't matter whether the machine is on a wired or wireless network. -- View this message in context: http://ros-users.122217.n3.nabble.com/ROS-and-virtual-private-networks-tp1480052p1480777.html Sent from the ROS-Users mailing list archive at Nabble.com.
