I have an embedded Linux running on a imx6 platform. This is a freescale embedded linux. The problem is that there is no sudo available for this linux, but I need to activate and deactivate the wlan0 device by a user. I tried to add the user to the group root without any success. I also tried to add the whole command to the /etc/busybox.conf file, but this had no effect either.
How can I run this command as user without having sudo?
user@touch:~$ /sbin/ifconfig eth0 down
SIOCSIFFLAGS: Permission denied
su
to become root?
