Question:

I need to auto-start a GUI application that requires sudo.

I know I need to edit the sudoers file with:

sudo visudo

However, I don't know what to write in the file.

What I already tried:

sudo visudo

and then added the following:

nanostuff ALL = NOPASSWD: /usr/lib/AirVPN/AirVPN.exe

I also tried with:

nanostuff ALL = NOPASSWD /usr/bin/X11/airvpn

and

nanostuff ALL = NOPASSWD /usr/bin/airvpn

None of those worked.

By doing:

ps aux | grep airvpn

I get the following output:

nanostuff    6805  0.2  0.4 483520 17384 ?        Sl   17:13   0:01 /usr/bin/gksu -u root -m AirVPN Client needs administrative privileges. Please enter your password. mono /usr/lib/AirVPN/AirVPN.exe path=/home/nanostuff/.airvpn
