hi, I have the same problem, could you solve it?

allspawj commented 6 years ago

Sorry, did you set your ROS_MASTER_URI and ROS_HOSTNAME on the windows side?

DId you disable the windows firewall?

Can you verify from windows that you are able to ping your ubuntu machine from the command line, and ping your windows machine from the linux command line?

just today, I managed to set everything up correctly, I did not understand how to set ROS_MASTER_URI and ROS_HOSTNAME I eventually also set ROS_IP on ubuntu for enabling communication.

I write my configuration, maybe it can be useful again

VM with Ubuntu: 1) set the network in Bridged Adapter mode 2) ROS_IP = ip local network (ex 192.168.56.101) 3) firewall disabled

Windows 1) ROS_MASTER_URI = http: // ip-ubuntu: 11311 / 2) ROS_HOSTNAME = ip-windows 3) firewall disabled
