Re: [Freedos-user] File Access denied
Hi! (please use plain text mail without html) Is there anybody that runs Foxbase+ V.2.0 for DOS on FreeDOS? What I am trying to achieve is run a foxbase application on Linux with DOSEMU and freedos. Right. Maybe you get better results if you load SHARE... Please also compare diskimage (can be diskette or special DOSEMU FAT16 as generated by dosemu tools) drives to Linux directory used as drive drives. Problems when several users access the same file sound like shared file access problems :-). Even though no one is editing the file. The users should still be able to view the database even if no one is editing the current dbf file. Eric - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Freedos-user] File Access denied
Hi Eric, I did load share. Sorry I should have mentioned that. For testing purposes, linux permissions are open on 777 recursively, but still the same problem. I have been struggling with this for 2 months allready. Even tried putting the shared files on a CIFS server. Same results. Keith On Jan 17, 2008 4:33 PM, Eric Auer [EMAIL PROTECTED] wrote: Hi!

Re: [Freedos-user] File Access denied
What has been said here, a few months back, is that Samba server and CIFS clent is working ok with file locks. Also you should check wich version of FreeDOS you are using. It couls be helpfull do test with MS-DOS to make sure where the problem is. Of course, I assume that your works ok, with se same configuration on a non-dosemu setup ;-) Alain Keith Williams escreveu: Hi Eric, I did load share. Sorry I should have mentioned that.

Re: [Freedos-user] File Access denied
The Clipper DB, a dBase language compiler, had locking mechanisms that were similar if not the same as the FoxPro as I recall. I had a book or a document that covered these issues but I can't take the time to look it up until this weekend. Sorry. Just remind me on Saturday morning to go look for the reference. Right now I can give you some links to projects that have dealt with these file locking and permissions issues. The Harbor Projecthttp://www.harbour-project.org/is an Open Source Clipper DB like or clone that has an MS-DOS version. I have programmed applications for MS-DOS using Clipper DB which did give me some trials and challenges when trying to prove the locking worked as expected. The Harbor Project http://www.harbour-project.org/ used the same API's with some helper code. The problem may be more of the way FoxPro interpreted the MS-DOS locking API. The other part of the issue as I recall was that the MS-DOS API required a fair amount of extra helper code to be usable. As I remember some Assembly is required. The Oasis Clipper source archive http://www.the-oasis.net/index.php3 may be a source of locking coding examples for Clipper. That may give you some ideas as to what the FoxPro issue may be. A Clipper news groupnews:comp.lang.clipperis also mentioned on that page where you may get information. I'm sure there is also a FoxPro version of that news group. Cross OS's file permission information is a long discussed issue on the Samba.org http://www.samba.org web site. Samba has a way to share drives MS-DOS system. The rub there, as you mention, is the LINUX permission system. Add to that the locking issues and things get interesting. Does anybody have a debugger or debugging solution for observing file locks or file permissions. This appears to me to be a problem with all OS's. It is much the same problem as I struggle with LINUX, Win OS's, and the MAC environments. I hate writing debugging code all the time.

Re: [Freedos-user] File Access denied
Thanks for everybody's suggestions! It's great to finally get some input on this. Ok, maybe it would simplify things if I tell what I have tried... I have tried: 1. Different DOSEMU versions, v1.2 through v1.4 (+beta) - with different DOS version mentioned in point 2. 2. Different DOS systems, (MS-DOS 4 to 6.22, Dr.DOS, FreeDOS and even Windows 95 (ver.7) 3. Different server-side file sharing capabilities, NFS, SAMBA, etc. The ONLY working one under test scenarios was dosbox, but it did not help me any bit because dosbox has no printing support! Yes I know printing to a file and then printing out of the Linux system is a option, but it is not feasible in my clients situation or his program. I am beginning to think that the problem might be with dosemu + foxbase, because dosbox works so perfectly. Unfortunatly dosbox has no console-only (run without X) and printing support, otherwise it would have been done by now... Thanks for all the help! My next step would be to go CentOS + IBCS-3.4 with userspace x286emul. (Anyone got experience with that?)
