- After enable the
USERCTL
option in the network interface configuration file, it enables all non-root users to control this interface, and there is no more option to specify only the particular user/users to control that.
# cat ifcfg-eth0:1
DEVICE=eth0:1
USERCTL=yes
USERCTL=<answer>
where <answer> is one of the following:
yes — Non-root users are allowed to control this device.
no — Non-root users are not allowed to control this device.
