Assalamu Alaikum
dear fellows i installed the squid from source code. it is working nicely. then i paste the script to run the squid using service command in ( /etc/rc.d/init.d). "service squid start" command is working perfectly but "service squid stop" command in not working . please point out the error in the script.

#!/bin/bash

# well as bandwidth consumption.

what does "service squid stop" show on your screen? what do the logs say?

Isn't it amazing how so many people can type "linuxpakistan.net" into their browsers but not "google.com"?

I extracted the directories from squid rpm in a directory , then copied etc/rc.d/init.d/squid to / etc/rc.d/init.d/squid.
Then I opend vi / etc/rc.d/init.d/squid . Then the following code is opened.
Then I modify it as follows.

#!/bin/bash
# squid This shell script takes care of starting and stopping

if [ -f /etc/sysconfig/squid ]; then

exit $?



After modigying this code I can start the squid using command (service squid start )
But I can’t stop the squid using (service squid stop)
