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.
