How to make sure Squid is Running and doing it;'s job

satishap · 02-15-2008, 10:50 PM

Dear All
In RHEL 5.0 , I have installed DNS server and squid successfully.
Squid is also running fine. But is there any criteria by which one can make sure that squid is doing it's job i.e caching of pages.
also whenever I type following command
cat /var/log/squid/squid.out file, I got an error saying that
" FATAL : could not determine fully qualified hostname. Please set 'visible_hostname'. Though I have already set this option in /etc/squid/squid.conf say if FQDN is abc.xyz.com then I set as
visible_hostname abc.xyz.com

I also treid to put just hostname as abc but still same error pops up whenever I cat /var/log/squid/squid.out.

Please help me anyone I dought whether some configuration problem.

Please edit your squid.conf file and set visible_hostname there.

# vi /etc/squid/squid.conf

and set

visible_hostname myhost

here 'myhost' is the machine name. You may get the machine nmae by

# hostname

you can ensure that squid is running by doing following things

# ps aux|grep squid

Output of above command must contain 3 or 4 squid child process listing. If above command returns nothing so its means squid is not running.

2nd Method

Open a terminal window and tail the squid access.log file

# tail -f /var/log/squid/access.log

or whatever location of access.log you set in squid.conf

and now open a browser window and try to access some websites and then watch terminal window. Your all internet activity must be shown in terminal window. If you are getting output from access.log file its means your squid is running.

I hope this will help

Just found this thread, & it reminded me that I have long suspected that squid is not doing its caching job on my perimeter firewall -- a SmoothWall Express 2.0 box.

This may be a foolish Q since I am moving to SmoothWall Express 3.0, but doesn't this look like squid is running, but not doing any caching:

Code:

# ps aux|grep squid
