URGENT case. Experience on Squid content filtering needed


Good day,

I am under pressure from a customer, if anybody can, please help. I have to solve difficult situation.
I have internal network, 30 computers, changing users at the computers, users shall have different internet access rules, it is not possilble (customer denied it) to give each user his own login and pass to squid, because they would tell each other, so everything shold be done withou users action. They use Win XP and IE6, so no automatical configuration of proxy username and pass is possible. Only what we can is, to pre-configure proxy using Active Directory system policy, for each user - this applies to him if he loggs on anywhere.
For simplicity, lets think that users are divided into two main groups, Group1 has access to everywhere excluding adult content, gambling, etc. ; Group2 has access only to .cz domains and also not to adult content, gambling, etc.

I thought of running two proxies, on different ports, for the groups, but it seems that squid cannot run on two ports, and divide requests by it. Also I do not know which other, filetring - capable proxy use, if I will run one squid (for Group2) and other one of Group1. Please, any idea how to solve the situation would help me a lot. With many many thanks, Jaromir

welcome to LQ!!!

yes, squid is able to use windows active directory for authentication... here's an example howto: http://kb.papercutsoftware.com/Main/...ctiveDirectory (more howtos are just a google away)...

the content-filtering would be dansguardian's domain: http://dansguardian.org/

having said that, a nice integrated solution for this type of job is smoothwall:

just my ...

PS: there's no need to write "urgent" in your thread titles... all LQ users' questions enjoy the same level of priority...

does the network use static or dynamic ips? my office lan has about 20 users so i use static ips which cleverly match their phone extensions

squid wouldn't need to run over two separate ports, you'd just have to create to acl's. one for each group.

there's also no need to worry about browser or group policy settings, just configure your proxy server to be transparent. the users won't even know they're going through a proxy until their web request gets blocked.

squidguard is a nice alternative to dansguardian. i also like making custom error pages that scare the crap out of the lan users
