How to configure squid 2.6 and how to make it transparent?

Thanks, in advance.

--ignore --

This can be done via the following rule.

1. install squid running on your host/gateway

2. setup iptables and ipforwarding

3. use the following rule in your /etc/sysconfig/iptables file.

-A PREROUTING -i <your lan interface> -s ! <the IP of your squid host> -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128

This will route all web traffic on port 80 to the squid port on your gateway/router host.

4. run service squid restart
5. run service iptables restart

should be working nicely,

tail -f /var/log/squid.access.log in an xterm

run your favourite browser on one of your clients on your lan

go to www.google.com, watch the squid log..

i configure the the proxy on centos5, after i give the command service squid start, it is giving a error message ,
init_cache_dir /var/spool/squid .... starting squid: [FAILED]

Hi,

when you are starting the squid service it may failed because it is looking for the cache dir. to create it run the squid -z command. than restart the squid service by service squid restart or /etc/init.d/squid restart.

Thanks.
