Question Rsync Has Unexplained Exit


I am trying to use BackupPC to backup a Windows XP client to a share on a Ubuntu 8.04 computer. The connection is established but within a few seconds rsyncd exits. Here is the log entry on the Windows computer:

2008/05/14 09:21:26 [3320] connect from dick-ubuntu (192.168.0.8)
2008/05/14 09:21:26 [3320] module-list request from dick-ubuntu (192.168.0.8)

Here is the entry on the BackupPC log:

2008-05-14 09:21:20 full backup started for directory
2008-05-14 09:21:20 Got fatal error during xfer (unexpected response: '@RSYNCD: EXIT')
2008-05-14 09:21:25 Backup aborted (unexpected response: '@RSYNCD: EXIT')

This occurs regardless of the length of the module-list.

Here is a typical module entry from the rsyncd.conf file:

[ASD]
path = c:/ASD
comment = ASD Program
auth users = dick,backuppc
secrets file = c:/rsyncd/rsyncd.secrets
hosts allow = 192.168.0.8
strict modes = false
read only = false
list = false

I can post an entire rsyncd.conf file, if desired.
Any suggestions would be greatly appreciated.

More Information

I followed the debugging suggestion in http://rsync.samba.org/issues.html:

Step 1: Stop backuppc

root@dick-ubuntu:~# /etc/init.d/backuppc stop
* Stopping backuppc... No process in pidfile `/var/run/backuppc/BackupPC.pid' found running; none killed.
[ OK ]

Step 2: start strace

root@dick-ubuntu:~# ulimit -c unlimited
root@dick-ubuntu:~# strace -f rsync --daemon --no-detatch 2>/tmp/rsync-$$.out

Step 3: Started backuppc from another window and forced backup of Windows XP client. This failed as before.

Step 4: Output results of trace:

*************************end of debugging info*************
I think the errors at the top of the list can be ignored for now. Please advise if I am wrong. At the bottom of the listing we see w looks like one or more rsync syntax errors but I am not sure how to interpret them.

Does options.c(889) refer to the 889th line of code or something else?

I interpret [client=2.6.9] to be the version of rsync running on the client. The download said it was 2.6.8, but that probably does not matter.

Is the 76 an error code from rsync? If so, where may I find a listing?

Here is the .pl file for the Windows computer with the username and password fields modified:

$Conf{XferMethod} = 'rsyncd';
$Conf{RsyncdUserName}='UUUU';
$Conf{RsyncdPasswd} = 'PPPPP';
$Conf{XferLogLevel} = 2;
$Conf{RsyncShareName} = ['KandAClients','CitizensBank','AscendFCU','K&ABusinessDocuments','Kulp&Associates','USAA','Lions','T SEPWin','TIAA-CREF','VS2005','WACC','ASD','AdvancedInstaller','GenericRegistration'];
$Conf{ClientNameAlias} = 'dick-winxp';
$Conf{ClientCharset} = 'cp1252';

Here is the rsyncd.conf file on the client:

I give up on rsyncd, at least for now. The Windows shares are always mounted on the Ubuntu server so I thought I might do a tar on those shares. I get the following error: "No files dumped" when I try the following:

$Conf{TarShareName}= ['/etc'.'d$ on dcmqf61'];

and also on the following:

$Conf{TarShareName}= ['/etc'.'d$/TSEPWin'];

or

$Conf{TarShareName}= ['/etc'.'d$ on dcmqf61/TSEPWin'];

Where TSEPWin is a directory on d$. So, I clearly don't know how to address a directory in the mounted share. I also have not come upon the correct way to cd to a directory on the share.

I would appreciate the proper syntax and suggestions for using tar to backup a Windows share mounted on a Ubuntu 8.04 server.

Thanks in advance for helping this Linux newbie.

Good to see you found a workaround. Looking at post #2 around
Code:
write(2, "rsync: --no-detatch: unknown opt"..., 52rsync: --no-detatch: unknown option (in daemon mode)) = 52
it craps out, unfortunately only because of a misspelled switch: there's one "t" too much in "--nodetatch".

unSpawn,

Thanks for the correction. I will try rsyncd again.
