All the connections, from how many clients?<br>

type="cite">Hi guys, I need some help on configuring NLB for my
application servers. I've installed tomcat on 4 servers and I've
decided to use Linux HA for Network Load Balancing, but is seems
like all the connections are going only to one of the servers
(app-node-1). Can someone tell me what I'm doing wrong? It's
pretty simple config, just one clone resource (IPaddr2) running on
all nodes. Also, can someone tell me how is NLB done? based on
source IP, IP hash or... I need Round Robbin NLB.<br>
