[ULTRAMONKEY-USERS] help with streamlined HA LB cluster config on debian etch

[Jacqueline Buros]

Hi ..

I have a 2 identical linux machines, each running debian etch, each with 
one NIC (eth1).

Goal is to have both act as the "real servers", and for one to be the 
linux director with other as fallback. I would like for server loads to 
be balanced between both real servers, no matter which is the active 
linux-director.

I have set up heartbeat + ldirectord as described here : 
http://www.ultramonkey.org/2.0.1/topologies/sl-ha-lb-overview.html

Everything seems to work beautifully -- except, my packets are never 
forwarded to the localhost (except as fallback if I take the other 
realserver down).

The output of my ipvsadm looks like this:

  IP Virtual Server version 1.2.1 (size=4096)
  Prot LocalAddress:Port Scheduler Flags
    -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
  TCP  <virtual_ip>:www wlc
    -> <ip_of_ldirector>:www        Local   0      0          0
    -> host2:www                    Route   1      0          0   

I have read elsewhere that the linux packets will not be forwarded to 
localhost by default. Also, my checktype is "negotiate", and if I try to 
get the test.html page from the ldirector (as either 
http://localhost/test.html or http://<ip_of_ldirector>/test.html, the 
connection times out.

Can someone suggest how I might set up the connection so that the load 
is balanced between the realserver on the active linux director as well 
as that on the backup??

Many thanks in advance --
Jacki
