All, I am hoping someone can help with the following scenario:
- Dosemu 1.4 - Ubuntu 7.10 - TightVNC with java webserver - DOS based accounting package using Btrieve 5 database I wish to run a DOS based accounting package on dosemu with client access to it using VNC. I have had encouraging successes but the file locking issue still comes up sometimes. The accounting package uses a Btrieve 5 database. When I start several dosemu sessions using the same user all running the same accounting software, I get good perfomance with only an occasional crash due to file locking/sharing clashes. If I share the directory containing the software using SMB then mount it using CIFS: sudo mount -t cifs //server/share /other_location -o username=xxxxxxx,password=xxxxxxx then I also get the software to run properly although I have not been able to test whether this eliminates the occasional crashes I get without this method. I want to start different VNC sessions using different usernames and have them access the software. All these users are members of a group which has read/write access to the directory which contains the accounting software and which is lredir'd in the autoexec.bat. I have a script that starts VNC sessions like: su -c "vncserver :x" - user1 su -c "vncserver :y" - user2 However, when I run sessions with these different usernames accessing the CIFS mounted directory lredir'd in dosemu I get Btrieve error 14 (pre-image open error) when the software tries to access the data files. This is related to the .pre files that Btrieve creates and it appears a .pre file created by one user cannot be accessed by another, which is essential! Does anyone have any advice or recommended settings for enabling whatever oplock or other locking mechanism is required for this to work correctly? I notice several posts which say they have got record locking working using CIFS with SAMBA but no-one gives specifc smb.conf or CIFS settings for this. Any suggestions would be much appreciated.
