Hi everyone. As the subject says, I've run into this issue where BackupPC believes the connection is unsecure when it is not. I did some general debugging and info collection... #### #### ON BACKUPPC CLIENT #### # cat /etc/hosts.allow <empty> # cat /etc/hosts.deny <empty> # /usr/bin/rsync --version rsync version 2.6.8 protocol version 29 Copyright (C) 1996-2006 by Andrew Tridgell, Wayne Davison, and others. # cat /etc/rsyncd.conf motd file = /etc/rsyncd/rsyncd.motd log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid lock file = /var/run/rsyncd.lock port = 873 syslog facility = local5 max connections = 4 use chroot = no uid = root gid = root [web_backup] comment = Backups & Restores path = /websites auth users = backuppc secrets file = /etc/rsyncd/rsyncd.secrets # cat /etc/rsyncd/rsyncd.secrets backuppc:password #### #### ON BACKUPPC SERVER #### Software versions are: - Red Hat Enterprise Linux Server release 5.3 - BackupPC: v3.1.0 - File-RsyncP: v0.68 $ id uid=101(backuppc) gid=102(backuppc) groups=102(backuppc) $ cat /etc/hosts 192.168.0.67 myserver $ pwd /var/lib/BackupPC/temp $ ls -la total 8 drwxr-xr-x 2 backuppc backuppc 4096 Mar 19 20:24 . drwxr-x--- 8 backuppc root 4096 Mar 19 20:01 .. $ rsync -qazrt --delete backuppc@myserver::web_backup /var/lib/BackupPC/temp Password: <entered password> (a few seconds passed and then back to prompt) $ ls -la total 16 drwxr-xr-x 4 backuppc backuppc 4096 Mar 19 19:50 . drwxr-x--- 8 backuppc root 4096 Mar 19 19:45 .. drwxr-x--- 4 backuppc backuppc 4096 Mar 19 19:48 test_folder_1 drwsrws--- 4 backuppc backuppc 4096 Mar 19 19:48 www.mysite1.com (Confirmed rsync was working and authentication was required) $ ./BackupPC_dump -f -v myserver cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 myserver cmdSystemOrEval: finished: got output PING myserver (192.168.0.67) 56(84) bytes of data. 64 bytes from myserver (192.168.0.67): icmp_seq=1 ttl=64 time=0.101 ms --- myserver ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.101/0.101/0.101/0.000 ms cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 myserver cmdSystemOrEval: finished: got output PING myserver (192.168.0.67) 56(84) bytes of data. 64 bytes from myserver (192.168.0.67): icmp_seq=1 ttl=64 time=0.081 ms --- myserver ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.081/0.081/0.081/0.000 ms CheckHostAlive: returning 0.081 full backup started for directory web_backup started full dump, share=web_backup Connected to myserver:873, remote version 29 Negotiated protocol version 28 Error connecting to module web_backup at myserver:873: auth required, but service web_backup is open/insecure Got fatal error during xfer (auth required, but service web_backup is open/insecure) cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 myserver cmdSystemOrEval: finished: got output PING myserver (192.168.0.67) 56(84) bytes of data. 64 bytes from myserver (192.168.0.67): icmp_seq=1 ttl=64 time=0.095 ms --- myserver ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.095/0.095/0.095/0.000 ms cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 myserver cmdSystemOrEval: finished: got output PING myserver (192.168.0.67) 56(84) bytes of data. 64 bytes from myserver (192.168.0.67): icmp_seq=1 ttl=64 time=0.082 ms --- myserver ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.082/0.082/0.082/0.000 ms CheckHostAlive: returning 0.082 Backup aborted (auth required, but service web_backup is open/insecure) 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: auth required, but service web_backup is open/insecure -bash-3.2$ Now, I changed this to not require authentication just for testing... $Conf{RsyncdAuthRequired} = 0 ... and I got this error (snipped only relevant info...) $ ./BackupPC_dump -f -v myserver ... full backup started for directory web_backup started full dump, share=web_backup Connected to myserver:873, remote version 29 Negotiated protocol version 28 Error connecting to module web_backup at myserver:873: unexpected response: '' Got fatal error during xfer (unexpected response: '') cmdSystemOrEval: about to system /bin/ping -c 1 -w 3 myserver cmdSystemOrEval: finished: got output PING myserver (192.168.0.67) 56(84) bytes of data. 64 bytes from myserver (192.168.0.67): icmp_seq=1 ttl=64 time=0.094 ms .... So, I've confirmed everything is working on the outside of BackupPC. I found this thread which touches on what may be the issue: http://www.adsm.org/lists/html/BackupPC-users/2008-06/msg00295.html However, this "patch" did not work for me. Does anyone have a clue on what I could be doing wrong? Thanks! //Clint Alexander |
