I dont think there should be problem. I mean if a cyber cafe is running on
linux
chances are great in number that it is running on squid and iptables /
ipchains.

Anyways, I have cyber cafe of 30 machines ( windows clients)
and a linux server RedHat 7.2 enigma. I am using squid + iptables
and djbdns as dns server.

As far as i find out, i want to dynamically creat rules for iptables
which can enable/disable access from perticular ip for perticular time.

I am doing some r&d with perl if it can do it.
dont want to use php interface, instead i will use some application server
like apache + tomcat and servlets at client side.

So what i am planning is,
1) admin will give user a username and password , which
will be valid for perticular time period say 1 hr.
2)user will go to perticular terminal. by default iptables has disabled the
access to net.
3)user will browse for http://192.168.1.1/billing and will be provided a
form.
4) he will enter username and password and this will enable access of that
terminal for
already decided time period.
5)after 1hr, iptable will disconnect the server from net. ( drop packets at
gateway from this ip).

So
1)firewalling will be done by iptables.
2)caching will be done by transperent squid proxy.


Your inputs are most welcome.
