“Capture the Flag (CTF) is a computer security wargame. Each team is given a machine (or small network) to defend on an isolated network. Teams are scored on both their success in defending their assigned machine and on their success in attacking other team's machines. Depending on the nature of the particular CTF game, teams may either be attempting to take an opponent's flag from their machine or teams may be attempting to plant their own flag on their opponent's machine.” – Wikipedia http://en.wikipedia.org/wiki/Capture_the_flag#Computer_security

WarZone is network segment physically located in brmlab hackerspace, isolated from other network infrastructure and remotely available via VPN. Files needed to access prepared Warzone VPN are downloadable here..

If everything worked well last lines of openvpn output should look like this (openvpn adds route to 192.168.66.x network):
Wed Aug 17 02:42:12 2011 /sbin/route add -net 192.168.66.0 netmask 255.255.255.0 gw 192.168.66.129 Wed Aug 17 02:42:12 2011 Initialization Sequence Completed
If you want to use NetworkManager to connect to Warzone, you can.
IP 192.168.66.4 (internal DNS name ctf.war) runs server with CTF challenge (capture the flag). Everybody should start at level00. Your task is to get the password to the higher level (level01, etc.). More information in /home/level00/README
Please, do not publish solutions to the levels! Keep it to yourself and let others enjoy competition same as you've did.
From the internetz:
In the brmlab local lan:
There is a parallel challenge with only one level so far but it's focused more on the logic than low level. This challenge is more difficult.
IP 192.168.66.8 runs server with Oracle database. Can you hack it?
