David,
Thanks for the info. I do not have a firewall in between the HA pair
and the tape server. In the tape server's .amandahosts, I put the host
names corresponding to the main interfaces of both the primary and
secondary boxes, so that if I need to use amrecover, it should work OK
(will test that soon). In the disklist, I use the hostname that
corresponds to the virtual IP.
Building awareness of multiple IP interfaces into the client is a Good
Thing(tm), IMHO. It would help lots of people working with
multihomed/firewalled systems. I don't have the ability to do it, but
I'll cheer and wave my pom-poms from the sideline... ;-P
