Hi, in your answer you missed another possibility: the squid proxy program can use ACL: you can easily set up allowed access times for each clients and a lot of other stuff; squid can even be used to filter certain sites. you also get log files and can check which places have been visited

It sounds interesting. I'm not sure I'd suggest squid as a security proxy. There seem to two different classes of web proxy software, those for firewalls (focus on security) and those for caching, content filtering and features (like Squid).

However, you're right. I should have mentioned that the features exist. I think you have to get some Squid plugins for some of these features.

(It never ceases to amaze me how many Linux/UNIX subsystems are "modularizing" with Perl modules, Apache modules, loadable kernel modules, Squid modules, Netscape Navigator/Communicator plugins etc).

Gustl ps: keep on the good work - i like your answers

I'm glad.

there is a nice guide at

i had to solve another problem: i am teacher and net admin in a technical high school; we have full internet access - but it is impossible to teach anything if the internet is accessable so i had to find a easy solution to "toggle" a whole classroom (= a subnet). i did it via a little script (which includes menues via dialog), which creates a file with acls for squid. teachers are allowed to call the script via sudo (needed to restart squid)
