[Linux-cluster] where would the VIP be?

[William Ottley]

Hey Chris! thanks!
I use centos 5.1, and I have kernel 2.6.18-53.1.4.el5 on all the machines.

SO I'll setup lo:0 to point to the VIP, and use the sysctl.conf...

thanks sooo much!!

Will

Morpheus: After this, there is no turning back. You take the blue pill

show you how deep the rabbit-hole goes.
