Dear All,
I have still struggled to set this up - this is *so* frustrating!
I have tried running ldirectord on another host with the same
connection and have established that the same node gives a problem -
so it is not a problem with local connections, but is a problem with
the setup of this particular node.
However the interfaces are set up identically and the same script is
used to bring the shared IP over. The RIP for the server works fine
from the command line using lynx. However, whatever I do, I do not
seem able to get any Active connections to go to this node, although
it does pass the health check and does pick up inactive connections.
The logs are as far as I can tell normal:

It is just that always there are 0 active connections:

Does anyone have any guesses and is there anything else that I can
post to help people track this down? As you can probably tell from the
above, I have 4 Real Servers, 83.223.121.71 - 83.223.121.74. I also
have a VIP ( 83.223.121.75) which happens to be hosted on the same
server as RIP1. However, when I move the RIP to be hosted on the same
server as RIP2 it still has a problem with Real Server 1.
Many thanks,
Alex Davies
