[Linux-cluster] Lars' method???

[William Ottley]

thanks Lon for the pointers. I've tried so many different methods just
to get this to work: lvs-dr, lvs-nat with 2 nics, no go.. I can't seem
to get anything to work.

so i'm doing serious google searches, and there's sooo many how-tos
that tell you to do this, or do that, etc. and i'm like well which
one? I'm on one now, that says for nat, create a copy of the eth1
(private IP nic) eth1:1 and assign 192.168.0.254, and use that as the
default gateway for all the RIP... is this true?

Thing is, i have to manually copy the eth1 file to eth1:1 and assign
the IP, yet with the virtual IP, eth0:1 is created automatically... so
this makes me believe something is wrong.

I use pulse / piranha: what tools can I use to test and see if web
traffic IS going to the RIP or not???

thanks!

Will
