Hi
I have a problem with Samba locking files from DOS or Windows aplication.
It Was tested on Samba 2.0.6, 2.0.7, 2.2.0alpha and RedHat 6.2 , RedHat 7.0 ,
Kernel 2.2.14-6.0.1 with attached configuration.
Example 1: Program Mana.exe created by VisualFoxPro 5.0 is runnig from Win98
local disk ( c:\mana\mana.exe)
and data path is set to //samba/server/manager .
Before I start program there will not open any files on Samba server.
When is program normaly closed server status is:
PID Sharing R/W Oplock File Date
2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/manr2001.dbf Tue Feb
27 17:02:44 2001
2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/mana2001.fpt Tue Feb
27 17:02:36 2001
2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/MANR2001.CDX Tue Feb

2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/manaadod.fpt Tue Feb

2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/manaadod.dbf Tue Feb

2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/MANP2001.CDX Tue Feb

2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/manp2001.dbf Tue Feb
27 17:02:44 2001
2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/MANA2001.CDX Tue Feb

2090 DENY_NONE RDWR EXCLUSIVE+BATCH /server/Manager/mana2001.dbf Tue Feb

This problem exists only on Samba server and is critical for use database
systems (when data are shared with another user).
Novell or Win98 network is working correctly.
This problem exists with a lot of programs.
Example 2: Pictures saved on Samba server in directory Progres.
When the files are viewed and closed (by irfanview.exe) the
file, who was viewed as last, stayes opened.
Open Files
PID Sharing R/W Oplock File Date
2703 DENY_NONE RDONLY EXCLUSIVE+BATCH /server/Progres/lhw2.jpg Tue Feb

Please tell me, what can I do.
Thanks

We are implementing samba based on the CIFS document. We are stuck with implementing the LOCK_BYTE_RANGE. If the CIFS document is to be referred, then we see that there is no field in this message that indicates if a read/write or unlock message is being sent by the client. So our question is, how does one determine what kind of locking the client has requested. Thanks in advance, Saugata Das
