Hi lokesh21

Personally it's difficult to answer your question. You don't provide enough detail.
First I'd like to know is, are you sure squid is running and internet connection is proxy-ed trough squid?

This is from the SquidFAQ, http://wiki.squid-cache.org/SquidFaq..._porn_sites.3F, maybe it will help?

I set up my access controls, but they don't work! why?

If ACLs are giving you problems and you don't know why they aren't working, you can use this tip to debug them.

In squid.conf enable debugging for section 33 at level 2. For example:

debug_options ALL,1 33,2

Then restart or reconfigure squid.

From now on, your cache.log should contain a line for every request that explains if it was allowed, or denied, and which ACL was the last one that it matched.

If this does not give you sufficient information to nail down the problem you can also enable detailed debug information on ACL processing

debug_options ALL,1 33,2 28,9

Then restart or reconfigure squid as above.

From now on, your cache.log should contain detailed traces of all access list processing. Be warned that this can be quite some lines per request.

See also SquidFaq/TroubleShooting.

I'm having a similar problem, I tried the steps listed on the FAQ and no success. Then I figured, well if it's a rule set, it must use some logic.

So I reversed the http_access as follows.

(this is the non-working config)


http_access allow subnet_1
http_access allow subnet_2
http_access deny blocksites

(this is the working config)

http_access deny blocksites
http_access allow subnet_1
http_access allow subnet_2

I restarted Squid and it's now blocking the site. Hope this helps.
