For our vocational school we need the above mentioned solution.
We have three classrooms with internet access. If we open the router (manually) everyone has access. In the Squid-Faq document 10 there is a very simple solution, for changes you allways have to edit the config-file. Someone told me about a cgi, placed on the primary web-page. The user has to start this cgi to get access to the internet - or will be told, that access is denied.
Can anybody give me some hints?
