HackLuNetwork

Network Design for the Hack.Lu 2005 conference

• Internet subnet - 192.168.1.0/24 (Zyxel to FW)
• Backbone network - 192.168.2.0/24 (connecting FW to WTH switches and some internet connectivity)
• Wireless network - 192.168.200.0/22
  • Allocated using RFC 2322 at entrance
• CTF backbone - 192.168.100.0/24 (Game server for WTH and "manager" of the WTH)
  • CTF Game server 192.168.100.1
  • CTF router 192.168.100.254
• CTF team n - 192.168.10n.0/24
  • CTF team server 192.168.10n.1
  • CTF team router 192.168.10n.254

CTF services

For the hypothetical Jungle books vendor :

• MathSin?-Echo - a standalone TCP server waiting for a value and reply with the sin(value) using TCP port 5556.
  • The server is given in binary only. The sample client is binary only too.
    • After the CTF, we give the full source code of the application. (adulau)
• ServicesRPC? - is a standalone Perl HTTP daemon acting as RPC-XML Server on TCP port 8080. (adulau)
• Vendor Management web application (sascha)
