block specific websites via proxy
Hi, there are a few sites that children use which we're not too keen on, but the county proxy lets them through ok. They aren't dodgy, but are pretty much social networking stuff, and we are keen to disallow these site (causing exlcusion/inclusion issues).
Is there any way that I can set up an intermediate proxy? Some simple free software would be great that means I change the IE proxy settings to point to that machine, and then the proxy software on that machine checks against an editable list, and either disallows or forwards on to the county proxy? I'm not hugely knowledgeable in *nix, but will have a go. We have a ubuntu machine hosting FOG, which isn't in constant use ( it's P4 2.8Ghz though).
Also, will this have a huge hit on performance, and will I need a really high powered spec machine?
Proxy and Hosts File - override?
Further to my original post, I've been investigating the use of the hosts file in c:\windows\system32\drivers\etc\. This is one way to set blocked sites on a local machine. I like this method as it should be quick and is easy to update.
The idea would be to have a master hosts file on the server, and then update the remote machines hosts file on startup.
However, I've read that the proxy server takes first pick for DNS, so the hosts file will not get a look in.
Anyway know a way around this? Want the host file to take presidence over the proxy.
