Let me start off by saying this: I know what I'm doing. I've been running backuppc for about two years on two servers, backing up about 25 servers (mix of windows and linux).
This is the ONLY machine I've ever had this problem with that wasn't SSH authentication problems, and what's worse is that it worked for almost a year before it stopped working. I'm convinced it's something about the shell or environment of the client system, but I've been trying to figure this out since last *November* and I'm just not getting anywhere with it. Every single hit just says "your SSH keys are messed up", but they most certainly are /not/ messed up, as evidenced below. All of the configuration is the same as my other linux servers. I can find absolutely nothing preventing this from working, but it fails every time! Please. I'm _BEGGING_ for something here, I have NO idea where else to look! There is unfortunately no extended troubleshooting information available in the documentation located at http://sourceforge.net/apps/mediawiki/backuppc/index.php?title=ErrorMessages or http://backuppc.sourceforge.net/faq/ssh.html or http://backuppc.sourceforge.net/faq/BackupPC.html#step_5 The target machine is CentOS5 running cPanel, and I've updated rsync to rsync-3.0.7-1.el5.rf (from RPM Forge, had to do that on another box as well). What else can I do to find extended debugging information? The xferlog always says: full backup started for directory / (baseline backup #259) Running: /usr/bin/ssh -q -x -l root TargetServer /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 2924 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) Not saving this as a partial backup since it has fewer files than the prior one (got 0 and 0 files versus 0) Yet, from a shell on the BackupPC server, as the backuppc user, I have no problems SSHing to the target: [backu...@backuppcserver ~]$ ssh r...@targetserver Last login: Mon May 10 19:36:24 2010 from 192.168.50.1 -bash-3.2# [backu...@backuppcserver ~]$ ssh r...@targetserver whoami root [backu...@backuppcserver ~]$ ssh -q -x -l root TargetServer Last login: Mon May 10 19:42:03 2010 from 192.168.50.1 -bash-3.2# [backu...@backuppcserver ~]$ /usr/local/backuppc/bin/BackupPC_dump -v TargetServer cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 TargetServer cmdSystemOrEval: finished: got output PING TargetServer (192.168.50.2) 56(84) bytes of data. 64 bytes from TargetServer (192.168.50.2): icmp_seq=1 ttl=64 time=0.133 ms --- TargetServer ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.133/0.133/0.133/0.000 ms cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 TargetServer cmdSystemOrEval: finished: got output PING TargetServer (192.168.50.2) 56(84) bytes of data. 64 bytes from TargetServer (192.168.50.2): icmp_seq=1 ttl=64 time=0.212 ms --- TargetServer ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.212/0.212/0.212/0.000 ms CheckHostAlive: returning 0.212 full backup started for directory / (baseline backup #259) started full dump, share=/ Running: /usr/bin/ssh -q -x -l root TargetServer /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --port=38271 --ignore-times . / Xfer PIDs are now 3040 xferPids 3040 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) cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 TargetServer cmdSystemOrEval: finished: got output PING TargetServer (192.168.50.2) 56(84) bytes of data. 64 bytes from TargetServer (192.168.50.2): icmp_seq=1 ttl=64 time=0.167 ms --- TargetServer ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.167/0.167/0.167/0.000 ms cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 TargetServer cmdSystemOrEval: finished: got output PING TargetServer (192.168.50.2) 56(84) bytes of data. 64 bytes from TargetServer (192.168.50.2): icmp_seq=1 ttl=64 time=0.165 ms --- TargetServer ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.165/0.165/0.165/0.000 ms CheckHostAlive: returning 0.165 Backup aborted (Unable to read 4 bytes) Not saving this as a partial backup since it has fewer files than the prior one (got 0 and 0 files versus 0) dump failed: Unable to read 4 bytes Any help or tips are greatly appreciated.
