Sometimes you just want to change the port which SSH listens on
Recently I had to build a startup script which added a user to the sudoers file. I figured doing something like
echo "something here" >> /etc/sudoers would be enough, but how wrong was I.
Many moons ago I used to manage several hundred servers for a company I worked for. Whilst it was fun it also proved very tiresome as menial tasks, such as changing the port SSH listens on, becomes very tiresome moving server to server.
