I am running squid proxy on my centos 5 machine.Now i want to configure squid guard on it. I have installed the squidguard on it and also tested it with squidguard -d command an it is running fine.

But as soon as I put a command

redirect_program /usr/local/bin/squidGuard -c /usr/local/squidGuard.conf

at the end on my squid.conf file and try to restart squid service it neither stops nor starts it say 'failed'.

When I go into service configuration and try to see the squid service the following message is being displayed

"squid (pid 21470) is running...
FATAL: Bungled squid.conf line 4538: redirect_program /usr/local/bin/squidGuard -c /usr/local/squidGuard.conf
Squid Cache (Version 2.6.STABLE21): Terminated abnormally."

Kindly help.

Error simply shows that at the last line of your squid.conf file, the entries are not correct. You have to check it again properly.

What is the correct syntax of this line. I have checked from the net and then I have written it.

Can you attach your squid.conf file, so that it will help us in looking into the problem in detail.

I am attaching the squid.conf file and also the squidguard.conf file for you.

One more thing which I wanted to ask. On the net at many places it is written to write a following line in the config.sys file.

url_rewrite_program /usr/local/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf

and at many places they tell to write the following line.
redirect_program /usr/local/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf

Are the one and the same thing or is there any difference.

More over where the above line should be added in the config.sys file.

Your last line should be this one-
Check the configuration file of squidguard, it should be in /usr/local/squidGuard/ directory.
Put this above line at last line of your squid.conf file and try to restart the service, it should run.

I have put the line
url_rewrite_program /usr/local/bin/squidGuard -c /usr/local/squidGuard.conf

but stil after restarting the squid service it is saying failed.

Again you put the wrong line-
url_rewrite_program /usr/local/bin/squidGuard -c /usr/local/squidGuard.conf

The correct line is-
url_rewrite_program /usr/local/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf

Sorry that was a typo error in fact I had put the below line

url_rewrite_program /usr/local/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf

the squid service is failing to restart. Only after i comment this line the service starts.

Did you follow the configuration steps from http://www.squidguard.org/Doc/ website?
If you followed the steps from the above mentioned website, did you follow them correctly?
