samba - Jun 1999 - FILE CACHE/LOCKING DOES NOT WORK

The problem:
A file updated on a UNIX box (Solaris2.6) then viewed on a Win95 PC via
samba is fine, if you copy this file using Windows Explorer to e.g. your
desktop, this is fine first time. But, if you repeat this operation then
the file size reported by Windows Explorer is correct but the file size
reported on the local copy is still the original size. This operation needs
to be repeated several times (2-6) for the local copy to be updated
correctly.

This works fine with NT but is repeatable on Win95. I have messed with
oplocks,
sync and changed the registry in Win95 as per article in FAQ but with no
success.
I have checked that all the UNIX systems have the same smb .conf and that
they are
basically configured the same.

Details:
UNIX Machines: SUN/SUN Clones, Solaris 2.6
WINDOWS Machines: Windows95b
NT Machines: NT4sp4
The above experiment was done with a small .txt file
Version 1.19.16p10 OK
Version 1.19.18p11 BAD
Version 2.0.3 	BAD

Any ideas ?

Thanks

this is sure to be an oplocks problem (ie. Samba is behaving
correctly, it's just that you were expecting something different!)

set oplocks=no on the shares that you wish to access simultaneously
from Windows and Unix. Then remember to restart smbd before testing.
