Hi,
First off, many thanks to all those who responded to my plea for help
with
Piranha. Ultra Monkey looks much more interesting, so I thought I give
that a go.
I'm now trying an LVS/DR config with one LVS Router and three Real
Servers.
Heartbeat and ldirectord start up fine. All three Real Servers respond
to test page requests from ldirectord.
The problem is LVS does not appear to forward the requests to the real
servers.
Tcpdump shows some data is exchanged between the browser and vs1, but
nothing else happens.
Any help would be greatly appreciated.
TIA
Shaun
