Class a has 20 machines running nt client 4.0
Class b has also 20 with NT 4.0
Class c has 15 & with NT 4.0
I was thinking something like a dhcp type leasing system where ips are pooled together.
I did something like it about two years ago. I used the Squid redirect feature.
My setup was something like this:
- All clients have fixed IPs. Each classrom has his own subnet.
- I wrote a CGI-Script in perl that writes the denied IP or Netranges in a file
- The redirectors read this file periodically and act accordingly.
If the client is listed in the blocking file, it's request gets redirected to a "access-banned-errorpage".
See http://squid.visolve.com/squid/squid24s1/externals.htm#redirect_program for a quick overwiew on this subject.
Also www.squid-cache.org might have something interesting.
Unfortunately I can't send you the scripts right away, because I don't work there any longer. But if you are seriously interested, I can invoke some old connections and get it.
