hl-pyvpn

Revised Python version of the commandline OpenVPN solution for Hacking-Lab.com, originally created by Zy0d0x

Quickstart:

$ [sudo] apt-get install git python python-pip openvpn -y
$ [sudo] pip install pexpect
$ git clone https://github.com/ragerin/hl-pyvpn ~/hl-pyvpn/
$ curl -L -o ~/hl-pyvpn/hlca.crt https://media.hacking-lab.com/largefiles/livecd/openvpn-config/general/hlca.crt

NOTE: The SyntaxError when using pip(2.7) to install pexpect doesn't matter. [see pexpect issue #220]

Start it with:

$ [sudo] python ~/hl-pyvpn/hl-pyvpn.py

Requirements:

• python2.7 or python3
• pip or pip3
• openvpn
• pexpect-4.0.1
• the Hacking-Lab certificate (it can be downloaded from http://media.hacking-lab.com/largefiles/livecd/openvpn-config/general)

Usage:

$ python hl-pyvpn.py [-h] [--hostname HOSTNAME] [--port PORT] [--certificate CERTIFICATE] [--logdir LOGDIR] [--logvpn]

Arguments:

FLAG	ARG	DESCRIPTION
-h, --help	N/A	show this help message and exit
--hostname	HOSTNAME	sets the host address (default: 212.254.246.102)
--port	PORT	sets the port of the host (default: 443)
--certificate	CERTIFICATE	path to the certificate file (default: hlca.crt)
--logdir	LOGDIR	dir to place log files (default: /var/log/hl_pyvpn/)
--logvpn	N/A	if specified, all openvpn output is logged in log_hl_openvpn.log (default: False)

• There is usually no need to touch --hostname or --port unless Hacking-Lab changes it.
• --certificate should point to the path of the .crt-file downloaded from the link above. Alternatively the .crt-file can be named hlca.crt and placed in the same directory as the script, thus the --certificate parameter is not needed.
• The --logvpn flag specified whether the OpenVPN output should be logged to a file as well. NOTE: This will store your entered password as cleartext!!!

Please comment and critique. Also feel free to add pull requests with improvements. The state of the code seems to me alright, but it could certainly be refactored.
