I'm running BackupPC on a Centos 5.2 server (64 bit). It backs up linux 
with rsync and Win2K3 servers using smb, and has been running well for 
some months now.

Last week I did a yum update, and pickup up updates to samba:

Jun 26 15:25:06 Updated: samba-common.x86_64 3.0.28-0.el5.8
Jun 26 15:26:58 Updated: samba-common.i386 3.0.28-0.el5.8
Jun 26 15:28:19 Updated: samba.x86_64 3.0.28-0.el5.8
Jun 26 15:28:56 Updated: samba-client.x86_64 3.0.28-0.el5.8

Since then I begin to see the following errors in the backuppc logs:

...
and so on for many more lines. Notice the mangled directory names.

The linux backups are running OK, but on the windows servers, any 
directory with new files seems to be getting mangled. When I try to  
browse the backups in the web gui I get (in the LOG file):
2008-07-01 12:08:32 User admin (host=zin) got CGI error: Can't browse 
bad directory name /s
 To show what I mean by "mangled" I've put screen shots here:

The older backups look OK: I can browse, view the files directly from 
the web interface, and run a restore. 

Any ideas how to straighten this out? This looks like a samba issue with 
hebrew directory names, but maybe someone here can enlighten me as to 
the error:
SMB Signature verification failed on incoming packet!

Thanks,
Micha
