Hello - I followed Falko's tutorial on how to set up backuppc on Debian (I used Ubuntu) and everything went great except for the first backup of my Ubuntu desktop. I think there is an SSH error somewhere, but I do not know SSH all that well. The tunnel creation process went fine, with the last part not asking me for a password and displaying 'root'. Here is the XFer Log full backup started for directory / Running: /usr/bin/ssh -q -x -l root judas /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . / Xfer PIDs are now 6158 Read EOF: Connection reset by peer Tried again: got 0 bytes Done: 0 files, 0 bytes Got fatal error during xfer (Unable to read 4 bytes) Backup aborted (Unable to read 4 bytes) Where did I go wrong? Thanks
hi, sam problem here: I followed the how to religiously and it's working for my client, except that I'd like to back up the localhost as well and then I get the: ... Got fatal error during xfer (Unable to read 4 bytes) Backup aborted (Unable to read 4 bytes) the only difference with regards to the tutorial is that I've changed the TopDir variable to my external usb disk (/media/disk/backup) instead of creating a new partition on my server, and of course I've excluded that folder from the backup ones. I did check the permissions on both the config files and the destination directory and they are both owned by backuppc who's also the user for localhost. I don't know what I'm missing here.... thanks in advance, brunus
I have this same problem. One thing I've noticed is on the server as user backuppc when I run Code: ssh -l root clientIP whomai the reply is Code: root However, when I go by hostname Code: ssh -l root clientHostName It prompts the root for a password. Any ideas?
Nevermind. I found the problem. There was a change of IPs for server and client a month ago, and a "rechange" a few days ago. Added the IP to /etc/hosts and recreated the public/private key exchanges, and all is fine now. For those who are always prompted for a password, try this Code: ssh -l root clientIP whoami and ssh -l root clientHostName whoami clientIP: e.g 198.162.2.100 clientHostname: e.g. mediaserver One of the two should return Code: root while the other returns Code: The authenticity of host 'files (198.162.2.123)' can't be established. RSA key fingerprint is 67:3f:82:e4:1c:6a:71:b8:46:f3:8f:a0:28:c6:f2:25. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'mediaserver' (RSA) to the list of known hosts. root After that, run your backup and it should work just mine.
Backup aborted (Unable to read 4 bytes) Asegurate que el host que tiene instalado el servicio BackupPC tenga un nombre distinto a localhost. Cambia esto en el archivo /etc/hosts Ejemplo: # Do not remove the following line, or various programs # that require network functionality will fail. IPYOUHOST backuppc (nombre del host) 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 ------------------------------------------------------------------------------- Luego recien crea las firmas digitales y copias las firmas a los host remotos a backapear.
