It is me again. Still fighting this battle. ( I am pretty sure it is
something I have done setting up my network and not LVS, but I hope someone
can see what I have done incorrectly) I did not included all the past
responses since it would have been huge BTW, I am a programmer but since I
own my own lil company I am forced to be a sysadmin/network guy. So be kind
if I say something stupid.
Thanks for any help
Here is the readers digest version on the problem
After an amount of time(usually over night), the director can not longer get
to the outside world.
(Config stuff at the bottom)
When the director boots , everything works just fine. After a while I can
not longer get to the outside world(not entirely true more on that in a
minute) I notice the problem when I do a ipvsadm --list ( it takes about 40
seconds to come back ) If I do a ipvsadm --list -n it comes back
immediately.
Here is where it gets a little strange(at least to me) I can ping some boxes
on our network(with their public ips)
Before that here is some config info

Ie. Ping 66.208.187.21 (on of my webservers on a separate box - works fine)
Ping 66.208.187.126 (which is the gateway) works find
Ping 66.208.187.129 (one of the name servers ) Fails
Ping 66.208.187.133 (a web server on another box ) Fails
Ping anywhere outside world fails

One addition I did yesterday was from
http://www.linuxvirtualserver.org/VS-DRouting.html
Put in the arp workaround
echo 1 > /proc/sys/net/ipv4/conf/eth1/hidden
echo 1 > /proc/sys/net/ipv4/all/hidden
