how turn a linux server machine to a filter of web content?


hi,
i have a small network with 5 computers and i looking for a solution to prevent virus entry of machines by internet.
i have seen a network that use the windows small business for filter all content, but i dont want buy a software and because i know that linux its better so i want know if there is some especial distro for what i want to do.
the goal is have a server(linux) that is direct connect to the internet and them all computers link to that server and request the content that we want see from internet and if there is some site that have bad,ilegall,porn,virus,etc content simple block the request.
thanks for your help

i'd say your best bet is a firewall appliance like ipcop, smoothwall, pfsense or astaro. no need to learn to do it yourself really. much simpler to use ipcop and add a few addons via its web interface.

Aside from a good firewall,
You can install squid, and squid guardian on the server.

hi,
but that´s firewall only prevent the acess to certain sites or prevent the infection of virus too?
for example if i check my e-mail account and there is some virus atach the firewall will do something?
if i have a infected file that i copy to other computer on the network that firewall do something as well?
there is some update of database for the firewall like we have in avg,norton etc?
thanks a lot for your help

Sorry, don't understand what you mean. Whilst these are "firewall" appliances, they all run squid and AV.

i novice in linux so sorry for my questions...

what i want to do is monitorize and control all network comunication send files over the network and over the internet to prevent the infection of virus or spyware.
i have seen some firewall´s that you have tell me:

"Aside from a good firewall,
You can install squid, and squid guardian on the server."
"like ipcop, smoothwall, pfsense or astaro"

my question if this: with this software i will be protected agains virus and spyware that came from email etc or this is only to block some sites?

If you only use linux, you don't have to worry about viruses.
If you have window clients, you can install clamav, spamassassin

A firewall will not stop a virus it will block in coming and outgoing requests.
Squid and squid quard can help you to block access to certain sites.


I would suggest to do some reading on firewalls, squid, mail server, spamassassin, procmail, clamav....
Google is your friend.

As much as it's nice to stick ones head in the ground when it comes to viruses, there are still plenty of Linux related threats which benefit from AV. http://en.wikipedia.org/wiki/List_of...mputer_viruses
