Add an extra check for capabilities when executing the commands
See original GitHub issueBesides the execution of the commands as a root user, you can also employ Linux capabilities and apply CAP_NET_ADMIN and CAP_NET_RAW to tc and iptables in order to use them as a regular user.
In your root check , you could implement an extra check for those two capabilities and permit the execution or else raise an Exception or print an informative error. Currently, I am unable to use tcconfig tools due to that check and I have to modify the code and run it again.
How to use capabilities
Get the capabilities of a command:
getcap /sbin/tc
Set capabilities to a command:
setcap cap_net_raw,cap_net_admin+ep /sbin/tc
