Not sure why this didn't make the list last week? A gaff on my part? -pf
---------- Forwarded message ---------- From: Peter Farrell <[EMAIL PROTECTED]> Date: 23-Mar-2006 12:20 Subject: amrcover and nslookups that resolve hostname to more than one IP_ADDR (multi-homed servers) To: [email protected] Hi guys: I've got my setup working nicely. My 'amdumps' are working lovely and I can log onto *almost* every server to restore. Here is my problem: I've got multi-homed servers straddling half a dozen subnets. So nslookup for me is a bit tricky. In the example presented below - this host resolves to both of it's IP_ADDR to it's true hostname. But since the traffic isn't going through the interface that has precedence via my DNS the recover fails. I read in the documents that: ============================= If the tape server has multiple network connections, an amanda.conf interface section may be set up for each one and clients allocated to a particular interface with field five of the disklist. Individual interfaces take precedence over the general netusage bandwidth limit and follow the same guidelines described above in "Configuring Amanda": the limit is imposed when deciding whether to start a dump, but once a dump starts, Amanda lets underlying network components do any throttling. Individual Amanda interface definitions do not control which physical connection is used. That is left up to the operating system network software. While it's common to give an Amanda interface definition the same name as a physical connection, e.g. le0, it might be better to use logical names such as back-door-atm to avoid confusion. ============================= But this doesn't seem to address my issue. Is there anywhere that you can specify which interface to connect on a per/machine basis? Has anyone had a similar experience? *an aside: Why do the amdumps never work for directories on the tape_host itself? I always get time out errors on the tape_host when running amcheck, the 'results missing' for the reports (duh) as it fails to backup the disklist entry I've got. -------- vega.scarceskills.com /home/data/amanda holding-disk -1 local vega.scarceskills.com /etc full_dump -1 local -------- -Peter Farrell Below is an example of the failure I'm talking about: [EMAIL PROTECTED] root]# /usr/local/amanda/sbin/amrecover misc_backups AMRECOVER Version 2.4.5p1.
