Hi All, I've got a really weird problem; one which I'm quite sure I've run into before a very long time ago. I just can't remember what I did to fix it before.
I have the latest BackupPC release running on LinuxMCE (based on kubuntu 10.04). Let me just say I'm a RHEL/CentOS/Fedora user/admin. I don't know the ins and outs of Debian, much less Ubuntu. Anyway, the BackupPC install was straightforward, as always. If I kick off a full or incremental backup from the shell (as the "backupppc" user), the user logs into the remote machine and does a successful backup. I can see the results in the web interface for that host. If I let BackupPC do a scheduled backup, or I do manual backup from the web interface, the backups ALWAYS fails. The error I see in the logs is this (probably some ugly wrapping): full backup started for directory /boot Running: /usr/bin/ssh -vvv -x -l backuppc -t vmhost sudo /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --checksum-seed=32761 --one-file-system --ignore-times . /boot/ Xfer PIDs are now 26053 Rsync command pid is 26053 Fetching remote protocol Got remote protocol 1852141647 Fatal error (bad version): OpenSSH_5.3p1 Debian-3ubuntu7, OpenSSL 0.9.8k 25 Mar 2009 Checksum seed is 1598575443 Got checksumSeed 0x5f485353 Sent exclude: /proc Sent exclude: /dev Sent exclude: /tmp Sent exclude: /sys Read EOF: Tried again: got 0 bytes fileListReceive() failed Done: 0 files, 0 bytes Got fatal error during xfer (fileListReceive failed) Backup aborted (fileListReceive failed) Not saving this as a partial backup since it has fewer files than the prior one (got 0 and 0 files versus 0) That seems to be an error caused by an unsuccessful ssh login on the remote host. When I look at the remote's ssh log file after I enabled DEBUG2 for the ssh daemon, I can see the BackupPC machine tried to login with a SSH key first, then switched to password. The password obviously fails, and thus the remote server kicks out the "backuppc" user. I'm using keychain to cache the ssh key's passphrase. It kind of feels like the apache user, www-data, is trying to read the BackupPC user's (backuppc) ssh-agent, but is being denied. Does anyone know what's going on?
