High Availabilty with heartbeat and ldirectord

[tate_harmann]

Hello,
I am setting up a highly available, load balancing apache cluster. I think I have everything in place, and everything works except the load balancing. Heartbeat is used for the failover and works fine. I am using source hashing as the scheduling-method for ldirectord. Ldirectord does see the two nodes as the out put of "ipvsadm -L -n" shows:
SLES9-CLUSTER1:~ # ipvsadm -L -n
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.200.79:80 sh
-> 192.168.200.78:80 Route 1 0 0
-> 192.168.200.77:80 Local 1 0 0

And when I shut down one of the boxes, they are pulled from the pool and the master will roll to the other like it is supposed to. However, the actual web request on port 80 fails when going to the non-local node (192.168.200.78 in the above example.) It will come through fine on the local node. So about half of the web requests fail. I did enable ip forwarding, is there anything else I need to do? Oh, it is suse enterprise linux 9, and the service address gets bound to eth0 as eth0:0. I don't know if this is right, but most of the examples I found online set up the service address as lo:0.
I can post some config files if needed.

thank you,
