How do I tell Amanda to use a specific network interface if 2 exist on the system.

For instance I would like Amanda to only use the ce4 interface..

ce0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2

        inet 10.20.1.181 netmask ffff0000 broadcast 10.20.255.255

        ether 0:3:ba:9a:4f:6f

ce4: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3

        inet 172.23.1.73 netmask ffffff00 broadcast 172.23.1.255

        ether 0:3:ba:9a:4f:6f



this ought not to be an amanda issue, but rather an OS level routing issue.

if you ask amanda to backup computer blah.your.private.net, then your routing should direct the traffic through ce4. If you ask it to do blah1.your.other.net, then it should go through ce0. Your hostname resolution needs to resolve in such a way as to direct the traffic.

if you post more information about your OS and network configuration, someone might accidentally be able to help.

I note that the ethernet address of both ce0 and ce4 is the same. So they are virtual interfaces going out on the same wire.
