hacking-labs.com has some really awesome challenges which I am working my way through.

The connect script on the site was pretty good but i decided to make a more portable version that checks if the config files exist then if not it downloads all the config files. Runs openVPN in a new window. Then launches the event page as the website page with all the challenges. Forks a new process so that the resolv.conf will keep on being copied then on key press the child process is killed and the old config replaced.

#!/bin/bash
echo "$(tput setaf 2)Welcome to Hacking labs btr5 connect script by dwinfrey v1.1"
if ([[ -a resolv.conf.hacking-lab ]] && [[ -a client.ovpn ]] && [[ -a hlca.crt ]])
then
echo "All config files exist"
else
echo "$(tput setaf 1)Error, config files missing, Downloading config files"

echo "$(tput setaf 2)OpenVPN connection window will open"
echo "Login using your email/password"
gnome-terminal -x openvpn client.ovpn
read -p "Press Enter when successfully connected"
mv /etc/resolv.conf /etc/resolve.conf.back

killall openvpn
