Something about the default configuration of c-turtle installed via package manager precludes it from being used while my cisco VPN client is running. roscore will not start and fails with the following message: Unable to contact my own XML-RPC server, this is a highly unusual error and should be reported immediately. My URI is [http://"my_machine_name":37831/] Any tips or suggestions? -- View this message in context: http://ros-users.122217.n3.nabble.com/ROS-and-virtual-private-networks-tp1480052p1480052.html Sent from the ROS-Users mailing list archive at Nabble.com.
