Squid 2.6 with external link to block sites too slow

korexmohan · 12-01-2008, 01:36 AM

Hi friends,
I have configured Squid 2.6 with RHEL 5.2. When i am pointing squid to the extrenal file for blocking the sites, my system becomes very slow. Any suggestion or idea please...
Here is my acl conf...

acl spammers url_regex "/etc/squid/spammer_list"
http_access deny all spammers

the spammer_list file downloaded from sa-blacklist site with a size of 9 MB.

Why are you using a spam list in squid since I assume the point of the list is to identify spam email servers?

Hi billy,
I read most of your solutions in this site...really appreciate your contribution....
The file name says it's spammers (I named it like that) but it contains all porn sites and some of the unwanted sites to be blocked..

Maybe the external file is queried each time, squid processes an access. Maybe you should put that on a ramdrive or use an external url handler that caches the configuration file in ram.

That's fine - you'd be surprised what some people try to do though.

Brian's idea sounds pretty good.

The other thing you could do is try using a berkeley database file instead of a test file. I don't know if squid can use these directly, but you could use squidguard to intermediate
