samba - Oct 1999 - FoxPro's lock function over SAMBA file server

I have a very nasty problem on a small network using a linux 2.2.5-15 and Samba
2.0.3 (RH 6.0)
server and two clients Win95 and Win98.
    I have to use a program of commercial  administration made in clipper . On
Novell servers this
program works fine but on Samba server It does not allow that the two stations
access the same file
concurrently.
    The same problem is shown when in Fox Pro I am trying to use the lock
function on the same data
base from two stations.
    Problem is:

    1)  After setting a DBF.file on non exclusive access and locking a record of
this file with the
lock function on the other station ALL the records of the DBF file looks like
locked instead of
just one as settled.
    2) After setting locking=no in smb.conf  NONE of the records of the DBF file
is seen as locked
from the second station.

    So the Locking parameter in smb.conf makes ALL the records locked for Yes
and NONE of the
records locked for No instead only one as settled.

    I need very much an advice how to make the program working well since a
Locking = Yes does not
allow the program to be used concurrently and a Locking=No may be a problem of
data integrity.

    Thanks for all of you that have any suggestion

Hi Paul,

You mention that Locking=No may be a problem of data integrity. Doesn't
Clipper have its own record locking? I don't know Fox, but could it be that
you need to somehow enable record locking? That's how it works in Clarion.

By the way, there's a new Open Source version of Clipper coming out that
runs on all platforms including Windows and Linux. Now you can (drum roll
please) recompile your Clipper apps for Linux.
