fuckForticlient

fuckForticlient is a command-line utility to connect to SAML fortivpn servers by using openfortivpn and the --cookie-in-stdin parameter. This repo was formerly a Github gist. This script has been written for and tested on Debian GNU/Linux distros and derivatives. With minor changes, it may also work on RPM-based distros such as Fedora, etc.

Why?

Well, because the official Forticlient for GNU/Linux is total crap!
When I wrote this script, the main idea was to solve a problem that I though temporary... and, well, one year in and the official Forticlient GNU/Linux client is still total crap... so, heck, it looks like we'll be using this for quite a long time...

Alias

If you do not want to re-type every single time the command to connect to your FortiVPN provider, you can add this alias to your ~.bashrc file:

    alias vpn='FUCKFORTICLIENT_OPTS="--no-dns" fuckForticlient.sh -S VPN_SERVER -c'

After re-loading your ~.bashrc, you can connect to the vpn by simply running:

    vpn
