linux server not allowing client m/c s to browse websites.
 

hello,

i have linux server for shorewall and squid.
from yesterday client m/c s are unable to browse the websites but able to ping all websites ip adress and https sites are opening..
any help ?

It look like http policy or squid http cache is screwed up.

ok Thanks for reply.

How to resolve it ?
please help me

Try clean up squid cache at first.

1)Stop squid, and erase all the files in your cache directory
squid -k shutdown
rm -fr /var/lib/squid/cache/*

2)Re-create the swap directory structure
squid -z

3)Start squid again

thanks for your help.

But still not able to open the websites.
any idea ?

please help me

Then the issue may be in shorewall.
First, yoy can dump shorewall status to check whether any problem report.
shorewall show nat
shorewall show tos
shorewall show log
shorewall monitor [ delay ]
shorewall drop
shorewall reject

Second, if no error report, restart shorewall.
shorewall restart

shorewall not showing any error
unable to solve the problem.
if you need i can provide a login details.
please help me ?

thanks,

How about drop/reject and monitor report when client do Web browsing.
