Re: [BackupPC-users] stumped by ssh
I work nights, so, last night when I got home I sent my previous email. This morning I got up early and while (software) updating my backuppc server I decided to try sudo -u backuppc /usr/share/backuppc/BackupPC_dump -v -f [clienthostname] and the client is backup as I write this. What happened, I am asking myself. Last night I was running ssh -vvv [clienthostname] to test my ssh connection. ssh was 'complaining' that I had some bad lines in my /var/lib/backuppc/.ssh/known_hosts file. I removed those 'bad lines' with ssh-keygen -f /var/lib/backuppc/.ssh/known_hosts -R bob-desktop2 and long story short, this morning (half asleep) decided to let my backuppc server fail again trying to backuppc this troubled client. To my amazement, half asleep, it did not fail! Thank you everyone for your help. Somehow, during this journey, I stumbled onto the solution but, I might never have found it without the help of the mailing list. So, thank you everyone! Robert Wooden Nashville, TN.

Re: [BackupPC-users] stumped by ssh
Hi, If you are using a redhat 6 or one of it's clients check if you're using selinux. If so configure it's policies to allow ssh with keys loggin or put it in permissive mode.

But we got none. That rules out the .ssh keys and any obvious mis-configurations. When you rund BackupPC_dump part of what it runs is an rsync server on the client to be backed up. The rest of the script is a perl based rsync receiver. backuppc 32396 24278 2 09:31 ?00:00:00 /usr/bin/perl /usr/share/BackupPC/bin/BackupPC_dump -i hostname backuppc 32406 32396 0 09:31 ?00:00:00 /usr/bin/ssh -q -x -l root hostname /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive . This is where my knowledge breaks down BackupPC_dump tries to talk to the rsync --server... running on the client, but in your case it is failing. In our environment that's usually because the client disconnects from the network before any data is transferred. (We backup a lot of laptops that wander around). You'll have to see if there's any evidence that the client becomes unavailable after a backup is started. Also check that the 'rsync --server' is actually getting started on the client. -- Ray Frush Either you are part of the solution T:970.288.6223 or part of the precipitate. -*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*- Avago Technologies, Inc. | Technical Computing | IT Engineer -- Don't let slow site performance ruin your business.

One other thing that can cause trouble is any output sent before the rsync program starts (from /etc/profile, .bashrc, etc.). Stock rsync will ignore that and work anyway, but the backuppc implementation will fail. I didn't see any in your test, but perhaps you didn't paste the entire results.
