Hostname lookup failed
Hi to all, I have a problem with amanda. In december i've set-up amanda to backup the same machine that have the tape drive.

You should also be able to dig up more infos from your logfiles (lookup the parameter logdir in your conf, it leads you there ...).

[EMAIL PROTECTED] local]# ping auriga PING auriga.manord.com (172.30.2.195) 56(84) bytes of data. Your ping test is equivalent to doing host auriga. What Amanda is probably doing is the equivalent of host 172.30.2.195, a *reverse* DNS lookup. Your forward DNS may be working fine, while your reverse DNS might not be. Graeme

Make sure to let things settle in first before attempting too much optimization to fast. AMANDA adapts to your setup by learning from history, commonly spoken. Give it some runs of amdump to see the trends ... Yeah, I just put in some specific dumper thread options, and I'm going to leave it at that. Graeme

I was just thinking of writing something to do that. ;) Here's what I was thinking: a little PHP script that lets you choose a date (based on dates of logs available in the log dir). Once you've chosen one, it uses amdump / amstatus to generate a nice page of info for you in the main frame about that date, and caches whatever images it generates. Sound useful? Graeme

Re: Hostname lookup failed
I have had the same problem once, one of the machines that I back up sometimes wasn't found; I always thought it was some kind of time out problem since everything else worked (ping, dig). I ended up adding the machine in the backup server's /etc/hosts file. That should of course only be done if the ip address is fixed.
