Well, log level 10 certainly generates a LOT of information. :) Since the log files and dump file is almost 7 MEG tarred and bzipped, I am putting it on my web server for you to grab. Here is the URL: http://www.revpol.com/files/Arlofski-Autocad.tbz2 I had the client simply OPEN an AutoCad file, make a small change, and save the file. Thank you for your time and effort on this. I anxiously look forward to your findings. I'd love to put this to rest for my client. If you need ANYthing else, please ask. - Bill Arlofski [EMAIL PROTECTED] -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

[Samba] AutoCad 2004, Samba 3.0.11 & file locking issues
Sorry for such a long post as my first to the list, but in an effort to forego a long back and forth question/answer session via email, I think if I post all the information that I currently have someone may be able to more quickly spot my issue. The server in question is a Gentoo server running Samba 3.0.11. The basic problem is that when person A opens an AutoCad file, person B is unable to open the file and is told (by an Autocad dialog box): "Cannot find the scpcified drawing file. Please verify that the network drive is available and the file exists" Now, this Samba server replaced an NT 4 server and the client says that in the past, when ever person b tried to open an already opened Autocad file, they would be allowed to open it in Read-only mode, which is exactly what they expect and want to happen. So, on to the troubleshooting: I had my client open an AutoCad file called A1_1 and here is what tdbdump showed for that file. (info on the .dwl file is further below) # tdbdump /var/cache/samba/locking.tdb | grep A1_1 data = "[EMAIL PROTECTED]: got kernel oplock\AAa\00\00\07\9D\03\00!\00\00\00\96\01\02\00\B6\80,B\C9\A9\03\00\03\08\00\00\00\00\00\00\85\D6\0F\00\00\00\00\00\AF;\00\00/home/shared/projects/A1_1.dwl\00" data = "[EMAIL PROTECTED]: got kernel oplock\AAa\00\00\00\00\00\00\22\00\00\00\9F\01\02\00\B4\80,B\FF\E7\09\00\03\08\00\00\00\00\00\00\B3\B3\0A\00\00\00\00\00\1E;\00\00/home/shared/projects/A1_1.dwg\00" smbstatus shows: louis 25002 louis_laptop Mon Mar 7 08:25:49 2005 25002 DENY_WRITE 0x20196 WRONLY EXCLUSIVE+BATCH /home/shared/projects/A1_1.dwl MonMar 7 10:55:55 2005 25002 DENY_WRITE 0x2019f RDWR NONE /home/shared/projects/A1_1.dwg MonMar 7 10:55:53 2005 lsof -p 25002 | grep A1_1 shows: smbd25002 louis 27uR REG 8,3110753701363 /home/shared/projects/A1_1.dwg smbd25002 louis 61wR REG 8,352 1037957 /home/shared/projects/A1_1.dwl The .dwl file is a 'log file' that AutoCad uses to inform others that the file is opened and who it is opened by. Here are it's contents: louis LOUIS_LAPTOP Monday, March 07, 2005 11:02:28 AM If this user, Louis, tries to open this file again, Autocad tells him that "louis has this file open, would you like to open it as a read only file?" This is the correct functionality. This is how it's supposed to work when other network users attempt to open an AutoCad file that someone already had opened. And this is how it used to work on their NT Server. Instead, on the Samba server, when someone else on the network using AutoCad attempts to open that file, they get an error dialog of the nature "Cannot find the specified drawing file. Please verify that the network drive is available and the file exists" In another test, using Explorer, Louis was able to copy to his desktop an AutoCad drawing that was already in use by another user. I was initially thinking that we could over-ride samba's locking mechanisms for that share or something, but when he was able to copy an in-use file it started to look like an Autocad-specific issue rather than a Linux/Samba file locking issue. Any ideas that anyone can offer to help solve this would be appreciated. If this is strictly an AutoCad issue, I'd like to know for sure before we go to AutoCad with an issue. And again, if it is an AutoCad issue, why did everything work as expected on the NT server? Was NT ignoring AutoCad's file locking requests?
