hi there - i searched a lot in your archives,
and found some people with the same issue - but no solution - so there's
a new post .
setup consists of 4 servers with 1 nic each.
the director's VIP is bound to eth0:0
while the main IP is used for some control functions and so on.
on localhost is a thttpd watching and responding if i use lynx.
the balancing is working fine - every real server is recognized once up
and deleted when down.
I can surf the VIP and get response from the real servers as i wanted.
But if all real-servers are down, i got a connection reset.
tcpdump output looks like this on the director :

my ldirectord.cf looks like this :

autoreload=yes
logfile="/var/log/ldirectord.log"
#logfile="local0"
quiescent=yes
# A sample virual with a fallback that will override the gobal setting
virtual=a.b.c.d:80

real=a.b.c.g:80 ipip 1

receive="ok"
virtualhost=www.xyz.de
scheduler=wlc
#persistent=600
#netmask=255.255.255.255

The next thing is : Is anyone going along with feedbackd ?
I read something that there were some ideas to integrate it into
keepalived only i can see it nowhere
and feedbackd-0.4 master produces ugly warnings, when used with 2.6.17
does anyone have a clue how to fix this ?
thank you in advance,
Malte
