Just a couple questions if someone has experience. We have two real servers in 
an LVS-DR setup with arptables_jf load balancing ssh connections. These 
connections are sometimes kept open for very long periods of time and we're 
wondering how failover works with a setup like this.

 1.  Does the secondary lvs server which just started ipvs and sent gratuitous 
arp to take over the VIP send resets to those connections which it doesn't know 
about or does it simply not respond because it doesn't know the state of the 
 2.  Anyone have any experience with ssh load balancing and learned any good 
lessons that we can take advantage of?

Thanks much for your time.
