Use mtr w/o sudo

You have to allow mtr to use sudo itself so you don't have to start the command with sudo.

First change user to some working as admin. Then:

sudo chown root /opt/homebrew/Cellar/mtr/0.95/sbin/mtr-packet
sudo chmod 4755 /opt/homebrew/Cellar/mtr/0.95/sbin/mtr-packet

Then exit this user and do:

ln -s /opt/homebrew/Cellar/mtr/0.95/sbin/mtr /opt/homebrew/bin/
ln -s /opt/homebrew/Cellar/mtr/0.95/sbin/mtr-packet /opt/homebrew/bin/

Now mtr is working for this non admin user. Example:

mtr -z fritz.box
