Unable to communicate with master with roscore running
Hi, I am trying to subscribe to a node I launched on a raspberry pi on my laptop. I am able to SSH into the raspberry pi to launch the node (the problem is not that roscore isn't running because it is), but when I open another terminal and run rostopic list, the cursor blinks for a while before I get an "Unable to communicate with master" error. Both of my machines have the same ROS_MASTER_URI, which is http://cameraduckie.local:11311 . This hostname is the one that I ssh into from my laptop to launch the first node. I am very confused because the two machines can ping each other but the laptop cannot communicate with master--any insight would be greatly appreciated. Thanks, Taylor
