Create a shortcut on desktop that opens and execute a command with root permission in a terminal

Question

I want to create a shortcut that opens terminal and run sudo nethogs command without asking me for root permission.

Answer 1

There are two ways on how to solve this problem:

Grant nethogs the required capabilities

I think the easiest and safest way to do this is to make nethogs able to run without root permissions. You can do this by giving it the permissions it is currently temporarily acquiring as root every time you launch it. You can do that with the following command:

sudo setcap "cap_net_admin,cap_net_raw=ep" /usr/sbin/nethogs

Once you have given nethogs these capabilities, it should be able to capture your network traffic without root permissions and you should therefore be able to use it with a shortcut, without having to fill out any credentials.

Edit /etc/sudoers

However, a more general way of solving this sort of problems can be found here How do I run specific sudo commands without a password? Which basically tells you how to safely add nethogs or any other command to /etc/sudoers to be able to execute it without manually having to type in a password.
