Title: File locking - smbfs vs. NFS vs. ?
Post by: Eric on June 16, 2003, 08:52:56 PM

I'm testing a legacy DOS application under DosEMU on several Linux
workstations.  I want them to access the same datafiles on an e-smith
server (5.6 - upgrade 4) which currently uses samba (iBays).
File locking is faked - it does not really lock the files - so the
application is failing our testing.  We'd really like to use e-smith
for this but samba seems to be inadequate in the file locking area.
I've heard good things about NFS on Linux (except for security
which we can address).   What other options are there?  Has anybody
had to deal with this issue before?  Any suggestions or hints?
What about the Andrew File System (www.openafs.org)?

TIA

Eric

I presume you have installed Samba 2.2.8a and this does not provide a solution?

I have happily run a DOS accounting package written in AREV where the workstations were Windows systems, the file/record locking worked fine - do you require Linux w/s or perhaps execution under a Telnet session?

Have you tried to run your dos app under dosbox ?
What are your impressions of dosemu ?
I have been looking for a solution to run accpac plus on linux (clients)

Any comments

Regards
Dean

The system is running 2.2.7-3.7.3 (!)  I'll try to move to 2.8 when I build
the test server (next week).

Yes, we need Linux workstations.  We're looking into creating a definitive
file locking scenario so we can be sure of what's happening.

Thanks

I've not tried (or even heard of) dosbox... I'll check it out.  Thanks!

We've had success with dosemu for the tests we've been running.
It uses freedos although you can install another dos in it's place -
IBM's PCDOS comes to mind.  Compatability should be near 100%
then.

Thanks.
