well I think my interfaces are setup wrong, because while trying to test
this command occasionally I was able to hit my original web server (still
running on loadb1) but not actually in the ldirectord.cf file or listing
when I hit ipvsadm -Ln so I think I must have configured the race condition
somehow.
Can you explain which interfaces are supposed to be setup how?
I have a VIP loopback setup on all machines currently and thats obviously
not right ;)
on each machine I have
/etc/sysconfig/network with the gateway set
/etc/sysconfig/network-scripts/ifcfg-lo:0 with the virtual ip configured
/etc/sysconfig/network-scripts/ifcfg-eth0 with the real ip and gateway set
