Sirs: We are a Vinyl window manufacturing plant in central Washington State, USA. We have been running linux with samba for file and print services for eight or ten years now.
Much of our production software is in house, and built on CA clipper 5.2, using dbf files as the primary data store. The clipper dbf file format supports both record locking and file locking along with shared file access. This worked very well on Novell netware and was working ok on samba 3.0.23. We had a samba server running for several years. I believe it was 6.06 with samba 3.0.23 although I'm no longer certain of either of those two versions. We have about six stations running dos 6.22 and four running windows 98. They are part of production machines, and changing the operating system is not an option. I had managed to tweak the samba config file so that file sharing wasn't a big problem, the system was responsive and running fairly smoothly. We have numerous clients running winXP with no obvious problems. We are, and have been running the Samba server with User validation. We are part of a windows domain, but haven't figured out a way to have the dos machines login as domain members. The xp stations use the domain for authentication, then we maintain a parallel set of logins on the linux box and samba file server. Again, this was working OK, pre crash. A month or so ago, we lost two hard drives on the file server and had to do a rebuild. I had tried to update the samba version a time or two in the interem and failed. I couldn't get the dos machines to connect to samba and access the necessary data files. One gentleman on the samba list said that this was a problem with lanman protocol, and aparently fixed it. Samba 3.4.7 allows logins file access without any problems. The current problem is that shared clipper files are very slow. It appears as if record locking instead of file locking isn't being recognized by Samba. When production is going, 20 second delays for file access are common. This was not true six weeks ago before the server crash. I have studied on the smb.conf file at great length, trying several variations without sucess. Any advice or hints of what to study now would be most welcome, Jim Hurlburt Atrium Windows and Doors Northwest.
