Administration
Setup
Setup mostly involves running the script[1], however there are options which can be configured afterwards. The script will prompt for a user, password, and Key on first run, and any subsequent runs will simply update the vpn.
It provides a startup script in /etc/init.d, which can be launched by systemd.
Adding users
Users can be added to /etc/ppp/chap-secrets, which should provide them with a password and username.
