Locking problem

[Ota Neužil]

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 27 17:02:44 2001  
      2090 DENY_NONE RDWR  EXCLUSIVE+BATCH  /server/Manager/manaadod.fpt Tue Feb 27 17:02:44 2001  
      2090 DENY_NONE RDWR  EXCLUSIVE+BATCH  /server/Manager/manaadod.dbf Tue Feb 27 17:02:44 2001  
      2090 DENY_NONE RDWR  EXCLUSIVE+BATCH  /server/Manager/MANP2001.CDX Tue Feb 27 17:02:44 2001  
      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 27 17:02:36 2001  
      2090 DENY_NONE RDWR  EXCLUSIVE+BATCH  /server/Manager/mana2001.dbf Tue Feb 27 17:02:36 2001  




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 27 17:20:07 2001  



Please tell me, what can I do.

Thanks
