I write an UDP progam to tranfer files. The Virtual IP is10.45.8.200. The
UDP server binds VIP address.
And I use DR model for LVS. Using ipvsadm I can see:
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
UDP test1.local:8090 wrr
-> test2.local:8090 Route 1 0 1
-> test3.local:8090 Route 1 0 1
TCP test1.local:www wrr
-> test2.local:www Route 1 0 0
-> test3.local:www Route 1 0 0
For TCP, it works correctly, I tested it by using IE and apache.
But for UDP, I can see the server received client's request. But client
can not received server's response.
I search for LVS + UDP, but there is too little information.
So, I hope you can give us some UDP example to learn.
