I am trying to create a script that checks if my VPN connection is up and running...
Everything seems to work as except but for some reason, the script fills up my /var/log/auth.log with the below information
This is my script
Could someone please explain to me why/what I am doing wrong?
Do you really need to run ifconfig as root anyway? You shouldn't, if all you're doing is checking values.
Unless I am wrong... In Debian a regular user does not have access to ifconfig.

It took me all day but in the end, I was finally able to prevent the following log files to increase in size.
I took care of pam_unix(sudo:session) flooding my /var/log/auth.log by adding the below setting in /etc/sudoers.d/soichiro
To prevent /var/log/daemon.log to increase in size, I removed the printf in my script
To solve the /var/log/kern.log which was being flooding with messages from UFW like the below one, I executes the command sudo ufw logging off
I hope this will help someone out-there and if someone has a better way to do this, I am all hears.

Humor me. Just try it. I've never encountered a UNIX/Linux system which didn't allow you to read its network settings. I have encountered systems where it's not in the default PATH, but that didn't stop it from working when /absolute/path/to/ifconfig was used. And now that /sbin/ is mostly depreciated, that doesn't happen as much as it used to. 'which ifconfig' if uncertain.
Using sudo where unnecessary is a security risk. Someone could abuse those escalated privileges to change network settings. It could even conceivably happen by accident.
