How to ping a laptop by name? [closed]
The laptop can be ping by IP address, but not by name.
The raspberry pi can ping itself by name, but can’t ping the laptop by name. And the laptop can’t ping anything by name. Wonder if it’s something not on the laptop? It’s running Ubuntu on the laptop and rpi.
This question seems to be about basic Linux networking and doesn't seem to have anything to do with ROS. As such, I'm closing as off-topic. If you have something ROS-related, please comment, and I can help you re-open.
As one pointer, the issue you are having is most likely related to a DNS problem. Searching for that keyword might help you diagnose what is wrong.
I'm guessing this question came up when @notSoTechnical was following the ROS network (troubleshooting) guide on the wiki?
That is a good guess. Happy to re-open if you think that's the right move.
