OpenConnect 

pacman -S openconnect
  • using global protect, proprietary vpn used on many university campuses
  • problem: authentication isn't with SAML, but with some proprietary 2fa
  • surprisingly enough, just works, run openconnect
sudo openconnect --protocol=gp vpn.gatech.edu
  • have to paste in password with ctrl-shift-V
  • make sure mullvad is disconnected before
  • automate login with fish script
function vpn --description "connect to gatech's proprietary global protect vpn"
    # disconnect mullvad before continuing
    set -g mullvad_status (mullvad status)
    mullvad disconnect

    set password "$(pass school/gatech/gatech.edu | head --lines=1)"
    # 1st line is password, 2nd line is 2fa prompt, and 3rd line is gateway
    echo -e "$password\\npush1\\ndc-ext-gw.vpn.gatech.edu" |
        sudo openconnect \
            --protocol=gp \
            vpn.gatech.edu \
            --user=shuan7 \
            --passwd-on-stdin
end

function vpn-cleanup --on-signal SIGINT --description "post hook"
    # if connected before disconnecting, reconnect to mullvad
    if ! string match --entire --ignore-case -q -- disconnected $mullvad_status
        mullvad connect
    end
