problems with keep alive

Hello:

 

I have just set up a High Availability and Load Balancing configuration
following the instructions exactly as they are laid out in:

http://www.ultramonkey.org/3/topologies/hc-ha-lb-eg.html

 

When starting heartbeat on both nodes, the setup seems to work fine,
except that after 3 minutes or so, I can no longer reach the virtual
address on IPaddr2.  If I set a computer on the network to ping
continuously the virtual IP as a Keep Alive, then it continues to be
accessible, but then dies as soon as there is no longer a keep alive
ping going.

 

I of course cannot set up a keep alive ping to the virtual IP on either
of the two nodes because of the loopback device lo:0.

 

Does anyone have any ideas why this may be happening?  BTW - I am
running heartbeat over USB as you will note below.

 

I greatly appreciate any help or advice.

 

David
