Editing Sudoers to avoid typing a password for iwconfig command [duplicate]

Question

I wanted to follow this guide to avoid typing a password every time I want to use "sudo iwconfig" command

http://ubuntuforums.org/showthread.php?t=1132821

I tried the steps with "apt-get" command and it worked

sudo select-editor
sudo visudo
add %admin ALL=(ALL)NOPASSWD:/usr/bin/apt-get to the bottom line

but they didn't work with "iwconfig"

I believe the reason behind that is "iwconfig" source files are not stored in "/usr/bin/" directory because ls /usr/bin/ | less doesn't show anything named iwconfig

So, what is the directory I should enter before iwconfig?

Thanks in advance

Answer 1

Running iwconfig without password

Create a file called iwconfig in /etc/sudoers.d/:

$ sudo visudo -f /etc/sudoers.d/iwconfig

Add the following:

your-user-name ALL=(root) NOPASSWD: /sbin/iwconfig

Check if the file has the right permissions:

$ ls -l /etc/sudoers.d/iwconfig

Should be:

-r--r----- 1 root root 0 Feb 1 21:34 /etc/sudoers.d/iwconfig

If not:

$ pkexec chown root:root /etc/sudoers.d/iwconfig
$ pkexec chmod 0440 /etc/sudoers.d/iwconfig

If you cannot open the iwconfig file, try:

pkexec visudo -f /etc/sudoers.d/iwconfig
