Rviz ROS master incorrect ip address
Trying to run rviz in ubuntu 18.04
When running rviz, it says it's waiting for ROS master.
rviz: Waiting for master Could not contact ROS master at [http://192.168.31.200:11311], retrying...
But the ROS master is http://192.168.31.134:11311
Any assistance is appreciated
Edit: ROS_MASTER_URI=http://192.168.31.134:11311 my ROS_IP and ROS_HOSTNAME are commented out in bashrc
In the terminal where you are running
rviz, it would really help to know the values of the environment variablesROS_MASTER_URIandROS_IPand/orROS_HOSTNAME. Please edit your question and provide this information. You could runenv | grep -e "ROS_[M,I,H]"Also, if you want to do a bit of debugging while waiting for an answer, the value of
ROS_MASTER_URIshould behttp://192.168.31.134:11311(if that is where your master is running, as stated in the original question). The value forROS_IPshould be the IP address of the terminal where you are trying to runrviz(maybe 192.168.31.200).ROS_HOSTNAMEshould be unset.More info here:
