I'm trying to get Amanda working with SSH auth. After I installed it on a server and did a basic configuration with harddisk as tape, I got it up and running, no client support though. But I did get backups on my localmachine at least.

Then I wanted to get it working with SSH, and ssh-keys. One thing that is bothering me is that my local backups do not work anymore:

backup@backup-test:~$ amcheck DailySet1

(brought to you by Amanda 3.3.0)

Yes I know I got two localhost addresses but I wanted too make sure that is wasn't an error in name.

The other part as you see above is the EOF error on remote clients. Everything is in the same network and are all VM's on the same host-server. SSH is working both ways for the user I use. And what I've seen all permissions also. Here are a sample of my amcheck log:

I got no clue after reading guides and forums for this problem. Hopefully someone here might have a clue.

  • I am not familiar with Amanda configuration, but when you are configuring ssh, did you make the local backups done via ssh (i.e., the server ssh'ing to itself to run the backup) ? If yes, did you put the public ssh key into your authorized keys file on the local server ?

  • Thx, I over looked that part. It does ssh it self...

So, was the problem with missing ssh keys on the server itself ? If your problem was that, please mark it resolved, so that others can benefit from your experience.

  • It's was missing it's own public key, so ssh localhost didn't work. Also the "quoted string" error was solved by set quotes around the IP addresses. Not what I thought was needed. And last, can you mark it solved on a comment? I sure can't...
