Topic: Restricting internet access

[Mark Robinson]

Does anyone know if there is a way to limit peoples internet access  so that certain people ( depending on their user name and password or IP address) will only have access to certain specified sites. I'm wondering if it would be possible to do this with some configuring to the "rules" in IPCHAINS, or with SquidGuard the access controller for Squid.

Can anyone help me, give me hints or had any experience with IPCHAINS or SquidGuard.

Thanks

Mark
