Looking for a tool with given network admin functionality...
So I have a debian box set up as a router using iptables with dansguardian content filter and everything hooked up, and it is working well, but I am hoping to get some of the following functionality:
1. I would like to have user accounts set up so that the user has to log in before using the network, like they have in coffee shops and hotels. I should like to be able to direct internet traffic from different users via iptables or whatever.
2. I would like to at least be able to limit the amount of time that a computer (be it a user in the system above, or an IP address) is on the internet per day.
Does anyone know how to do either one of these? Is there an application out there to help me with this?
