Hello Guddu,
have you check logs? what it showing?

troubleshooting: [do this on the proxy server]

'tail -f /var/log/messages' in a seperate bash window while restarting squid
'tail -f /var/log/squid /access.log' in a seperate bash window while
attempting connections to the proxy server. watch the output for success & failure.

also check the configuration file

cd /etc/squid/

any recent changes there? thanks,

That could be an name resolution problem, a problem with the site's web server, or the page was moved.

Probably, your squid server is not causing those errors.

This errors may not be related to proxy. Try to open the web pages from the server, when squid is running:

lynx sitename
or
wget sitename

HI,

Check the squid server by
#ps -ef | grep squid

check /var/log/messages

I think, your squid is working fine check with google.com, yahoo.com.
#lynx google.com

if some sites does not open. that means there is some problem in sites wich you are trying to browse

Hi,
Check the squid log and /var/log/message
Or
Is there any acl you are using ? check that also.
