Hi,
Thanks for your answers. However it still doesn't work :S
I copied the output of the commands Wim sent me at the end of the email.
roswtf give me an error: Local network configuration is invalid: Local
hostname [ulster] resolves to [127.0.1.1], which does not appear to be a
local IP address ['10.1.1.146', '127.0.0.1'].
I don't understand as my ROS_MASTER_URI is correctly set.
echo $ROS_MASTER_URI
http://10.1.1.146:11311
Cheers,
Ugo
