Hello:
I set up two virtual machines on a CentOS 5.5 host.
Each virtual machine is running CentOS 5.5
I installed heartbeat and ldirectord on the machines
using yum.
My virtual IP is moving correctly from one machine to
the other, so heartbeat is working.
Here is something strange:
I can ping the virtual IP from the primary
and secondary machines, but not from anywhere
else. I tried it from the host machine, a
different machine on the local subnet, and a
machine on a remote network.
When I do an ifconfig on the first server, I see
eth0, eth0:0, and lo interfaces.
When I do ifconfig on the second server, I see
eth0 and lo interfaces.
As expected, the virtual IP is only enabled on the first machine.
If I reboot the primary, the virtual IP moves to the second
machine and stays there since I have auto failback off.
With that, I can still ping the virtual IP from either
machine but nowhere else.
It is stumping me that the I can access the virtual
IP from the standby server but not from other machines
on the local network.
Any ideas?
Thanks,
Neil
