Thanks for all your help Joe,
I finally got it working. it turns out I had to enable a linode ip
failover feature on my realserver. i added the director public ip/vip,
and things started flowing.
the ip failover setting in the control panel on my linode basically
allow multiple linodes to bring up the same IP.
I'll post a summary in this thread later on how i got it working on my
linode/XEN setup, so we can close this thread, and add perhaps add to
the docs.
Thanks,
-Vincent Young
