Hi all,
I've been happily using Amanda for some time now, but I seem to
have run into a recent snag. The backup server has multiple
addresses on a single interface and, for some reason, it has taken
to using the secondary IP as the source for Amanda communications.
This becomes a problem as I have firewall rules throughout the
network that specify the primary interface IP.
Is there a way to set the IP to use within Amanda? If so, can
someone point me in the right direction? I'm currently running
Amanda 2.5.1, though I'm looking to move to 2.6.1 soon.
So what changed on your system? It doesn't just randomly decide to
use a different IP. That's all controlled by things like the hosts
file. I control how my Amanda server addresses its clients by
putting explicit entries in /etc/hosts that match the entries in
Amanda's disklist. That allows me to keep the backups on the private
network, even though the server and a particular client may both
have IPs on the public network as well.
To my knowledge, nothing. At least, nothing on the network side of
things. Something ate the main eth0 config file a few days ago,
though, after upgrading a bunch of packages.. This is the only server
that was affected, though, so I'm still investigating.
Both eth0 and eth0:0 have IPs on the same subnet, so both are
technically valid, but after having used the IP on eth0 forever, I had
assumed that Amanda used the primary interface first. I suppose I'll
have to open the firewall a little to account for this other IP..
