Now i am testing a Squid server Failover.
One IP address (ex. 192.168.0.111) is allowed to connect to the internet

I have two RHEL5 Server having Squid installed on it. and i want to configure
Squid Fail over
using RHCS on those two servers. But I can't find in Resource List Resource
Like Squid Server
(As like Apache Server).
After that I wrote a script to start the Squid Server And added it as Script
resource but it
failed. The proble is that I am getting requests from clients at 3128 port of
Squid but they
won't connect to internet at all.
I have desabled SELinux and Firewall from the begning of this testing.
Squid can be rather funny with what IP addresses/interfaces it binds to.
I've found it works in a hot-failover setup (always runs on both servers)
if you tell it to bind to a port without specifying the IPs (so it binds
to all interfaces/IPs), and just fail over the IP - no need to bother
specifying the fail-over service. Mind you, same holds true for Apache -
you might as well have your servers as a load-balanced pair, rather than
warm spare fail-over.
