After running some ros::node, I want to clean the node killed by ctrl+C with rosnode cleanup. Howerver, it didn't work,and just keep dispalying unknow network error contacting node: timed out,and I even couldn't use ctrl+C to interrupt this command.

My roscore still run in another terminal,and I didn't set master/server in ros. My environment is Ubuntu16.04, ROS-Kinetic.

Anyone please help?
