Re: Samba and kernel oplocks - Solved????
Hi, I've been following this thread in the hope that it would help with a similar problem that I've been experiencing. Alas it doesn't help. The scenario: I am running a dos app from a shared samba directory on a linux server with both windows and dosemu clients. The problem: When the dosemu clients start the app first, the windows clients get the following message:- Cannot access the file N:\DATA\EQUITY\EQUITY.EXE. Make sure the file is a valid program and that it is not in use by another program. When the windows clients start the app first, the dosemu clients don't have a problem accessing the program or the data. I've applied the patch to dosemu from the previous posts on this thread with to dosemu 1.1.3 and am using the current version of samba. EQUITY.EXE is a clarion 2.1 based dos app that has been in use for years on all networks tested. Any ideas? Yours, Uwe.

I'm happy to say that the above patch allows Foxpro/Dosemu file locks to be recognized by Samba 2.2.4. This means I can run the Foxpro application via Dosemu and under MSDOS/Win98/Samba simultaneously! The only issue I had with the above patch is that the line numbers did not match my version of Dosemu 1.1.3.2 with keyboard patches. I had to insert the lines manually. Now onto stress testing to ensure the changes do not affect Dosemu stability. Thanks Sergey!

Dosemu file/record locking issues - anybody solved it?
Hi, for some time (about year) I'm trying to reach the compatibility of the dosemu file locking with dos/win workstations. It's not my first post about it, I have searched the archives, google, everything. I've tried the patches /the suggestions with no results. My situation: Heterogenous network, clipper application (dbf's) running simultaneously from dos/win and dosemu sessions, dos/win stations mount samba volumes (samba 2.2.3, linux rh73 kernel 2.4.18, but tried a lot of combinations in the past), dosemu uses lredired smbmounted drive. Problems: 1) dosemu clearly opens a file in deny-read (exclusive) mode even if it's opened in shared mode by some win sessions. It causes that our app crashes when starting on dosemu session. I've never saw the sollutions for this on lredired drive. 2) dosemu session can't see the record (file range) locks put by the dos/win session. There was a patch to some old version of Dosemu (made by some Polish student I think) which solved it for me but it was never sumbitted to dosemu developers or rejected by them - I dunno. The patches which arrived last month (??) - about foxpro locking issues which is I believe somewhat different from the clipper locking - didn't solve the problem. So, maybe there really exists someone who solved it in the similar environment as I use? Thanks alot if someone can help me.
