Hi Brian,

yes, ping works also as non-privileged user, hereafter the output:

Perhaps is a problem with the permission on the ping executable?

 

bwctl runs as user 'bwctl', but I noticed you are running ping as root.

 

Does you ping work as a regular user?

Hey Gaetano,

 

It looks like the ping command isn’t outputting anything, can you try running the following by hand:

 

ping -c 10 -i 1.000000 -W 1 -I 192.168.3.195 192.168.12.103

 

Cheers,

Aaron
