How to restrict user access to internet ?
I have a single box running sid with effectively always on broadband internet
access through ethernet and adsl modem, using pppoe. I need a simple way (not
for example squid which would use a lot of resources unnecessarily) to
disable access to the internet for some users (that is smaller children)
whilst not making it more difficult for others (my wife), such as by
requiring manual login/logout each time.
I'm sure there's an obvious answer to this but I have not found it by
searching either the mailing list archives or wider google searches. Help
would be very much appreciated.
