Distro/release for combined web filtering and fileserver
At the moment I have our webfiltering running through the last free version of Censornet on an old Athlon 1Ghz desktop machine and have an extra fileserver (Ubunutu, was CentOS) set up for lunchtime games, digital photos, CD serving etc running also running on a desktop machine... I've just inherited some decent server hardware and would like to can both of these machines and combine the function into the one server.
Do any of the 'instant filter' type distros - e.g untangle/schoolguardian/smoothwall express etc provide the same functionality in web filtering terms (or better ideally!) as Censornet but also offer basic Samba shares with integration into AD?
This would be the ideal solution for me as although I'm comfortable hacking around in Linux, I'm nowhere near an expert. I'm assuming the last freebie version of Censornet may struggle to run on newer (SATA raid) hardware and as far as I know it doesn't support file serving hence looking around first...
If that's not an option, can anyone recommend a good distro + walkthrough for setting up a webfilter which can double as a fileserver?
