I'm probably grasping at straws, but...
Do you think the fact that the ethernet cards are running in promiscuous
mode would affect anything? I checked my other LVS server (working) and it
does NOT have the ethernet cards in promiscous mode. Does anyone know how
to shut off promiscuous mode? I'm using an onboard EtherExpress Pro 10/100
card. The driver is in the kernel, not modular.
One other thing. The director box is a Cobalt RaQ 4r.
