Yes we are using SQUID. I plan to do that as First step... I have also located a couple lists of black listed site having over '000 os sites. I also plan to do block sie by Key words like "@#$%", "*****". How should I achieve this.
Any other suggestions... --Sandeep

Just one catch. blocking by keywords will also block valid sites. Like http://xxx.lanl.gov/ is a valid server at the los alamos national laboratory, but many companies block it.

I guess that will be the only down-side of this step. --Sandeep

no, you can take care of that.
we are an academic institution and have to take care of such sites.
see squidguard for more details.

[snip] the soln approach to ur prob can hav 2 approaches... --> A GPL 1 --> The usual Closed Source 1.... as for the gpl 1...there r numerous ways to get to achieving ur objective.
Using Squid as ur proxy with ACL's in place and url bannin depending on text in url's is possible thro Squid.
AFAIK....for trappin viruses is cocerned, u can achieve that by havin AMAVIS on the gateway in conjunction with a copy of either Macfee or Norton. Which can be configured to scan ur mail traffic for viruses. If there is nyhelp u want on this....u can always ask...or just meet me on yahoo msngr..."trevorwarren".

You can use squid for that. Does that quite nicely and efficiently.
We have thousands of users in IIT, and squid does it's task quite well. You'll find squid in your distro normally, else go to
www.squid-cache.org
then, there are many add-on tools do do porno blocking, bandwidth shaping (for MP3s and images etc). there are even lists of porno sites available. the one we use is "squidguard". search on google to get the homepage.

no ideas.

Very easy. Make a list of all porn sites on the net, and reject connections to them in your outgoing rules.
I also need to block downloads like MP3 etc. I have a cable connection it is being misused greatly.
Blocking specific file types is better done through a proxy. Actually, even blocking sites should be done through the proxy. Just use your firewall to redirect all outgoing connections on port 80 to your proxy.

What do you mean by blocking viruses using a firewall? If you want to scan all files that are downloaded, then you've first got to figure out where the viruses come through. scanning will have to be done at an application layer, so again, a proxy will have to do this. You'll also need to put something into your mail gateway. something like amavis.
Read the relevant HOWTOs for more info.
