read/write,write/write lock with smbclient fails
Hi,
We have smb client running on two of the linux boxes and smb server on another linux system. During a backup operation which uses smb, read of a file was allowed while write to the same file was going on.Also simultaneous writes to the same file were allowed.Following are the settings in the smb.conf file:
lock directory =/var/samba/lock
locking=yes
strict locking = no
oplocks=yes
level2 oplocks = no
kernel oplocks =yes
raw read= yes
raw write = yes
Could anyone please let me know that what can I do to disallow read while write is going on and also restrict simultaneous writes?

NAME
cupsaddsmb - export printers to samba for windows clients
SYNOPSIS
cupsaddsmb [ -H samba-server ] [ -U samba-user[%samba-password] ] [ -h cups-server[:port] ] [ -v ] -a
cupsaddsmb [ -H samba-server ] [ -U samba-user[%samba-password] ] [ -h cups-server[:port] ] [ -v ] printer [ ... printer ]
DESCRIPTION
The cupsaddsmb program exports printers to the SAMBA software (version 2.2.0 or higher) for use with Windows clients. Depending on the
SAMBA configuration, you may need to provide a password to export the printers. This program requires the Windows printer driver files
described below.
SAMBA CONFIGURATION
cupsaddsmb uses the RPC-based printing support in SAMBA to provide printer drivers and PPD files to Windows client machines. In order to
use this functionality, you must first configure the SAMBA smb.conf(5) file to support printing through CUPS and provide a printer driver
download share, as follows:
[global]
load printers = yes
printing = cups
printcap name = cups
[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
public = yes
guest ok = yes
writable = no
printable = yes
[print$]
comment = Printer Drivers
path = /etc/samba/drivers
browseable = yes
guest ok = no
read only = yes
write list = root
This configuration assumes a FHS-compliant installation of SAMBA; adjust the [printers] and [print$] share paths accordingly on your system
as needed.
MICROSOFT POSTSCRIPT DRIVERS FOR WINDOWS
The base driver for Windows 2000 and higher is the Microsoft PostScript driver, which is available on any system running Windows 2000 or
higher in the %WINDIR%SYSTEM32SPOOLDRIVERSW32X863 folder for 32-bit drivers and %WINDIR%SYSTEM32SPOOLDRIVERSX643 folder for
64-bit drivers.
Copy the 32-bit drivers to the /usr/share/cups/drivers directory and the 64-bit drivers to the /usr/share/cups/drivers/x64 directory
exactly as named below:
ps5ui.dll
pscript.hlp
pscript.ntf
pscript5.dll
Note: Unlike Windows, case is significant - make sure that you use the lowercase filenames shown above, otherwise cupsaddsmb will fail to
export the drivers.
OPTIONS
cupsaddsmb supports the following options:
-H samba-server
Specifies the SAMBA server which defaults to the CUPS server.
-U samba-user[%samba-password]
Specifies the SAMBA print admin username which defaults to your current username. If the username contains a percent (%) character,
then the text following the percent is treated as the SAMBA password to use.
-a Exports all known printers. Otherwise only the named printers are exported.
-h cups-server[:port]
Specifies a different CUPS server to use.
-v Specifies that verbose information should be shown. This is useful for debugging SAMBA configuration problems.
