Typical examples of wargame servers are the ones from Pullthe plug http://www.pulltheplug.org/wargames/
My questions are:
Can you advise on level of complexity? — i mainly intend to target medium to advanced users (but unfortunately i hardly make a distinction)
Can you advise on software to be used?
Which environment is better? virtual machines, real machines, some faked simulation?
What forensic tools to be deployed? tripwire and snort are good candidates
Should i record all the generated traffic for later analysis etc?
Have you ever stumbled on a tool/framework/general howto for realizing such service?
Ald finaly Can you propose some subject/theme? — I am kinda tempted to create something based on The Hitchikers Guide To The Galaxy but that's prety distant for the younger people (at least in my country)
And yes, please excuse me for my many questions *WINK*"
