We're having a problem with an application called Grade Machine
running on Windows 98 workstations. The problem occurs when
trying to save when overwriting the currently open class file.
It works on NT 3.51, it works on the local drive, it works
on Samba when short directory names are used, it doesn't
work under Samba 2.0.10 or 2.2.2 when saving to a file in
a folder such as "My Documents". We've tried with and without
oplocks. Samba 2.2.2 is running under Linux 2.4.9, while
Samba 2.0.10 is running under Linux 2.4.2.
I've tried to reproduce the problem using SMBCLIENT, without
success.
The configuration uses Samba's default case conventions:
default case = lower
case sensitive = No
preserve case = Yes
short preserve case = Yes
mangle case = No
An ethereal packet trace of the file save indicates that
at some point, the application believes the class file is
no longer present and so tries to create a new file of that
name instead of writing to a temp file and renaming. The
full trace of the save operation runs to 150 pages but this
seems to be where the failure occurs. The client asks for
a valid filename (although capitalisation is different under
Linux) and receives a garbage answer.
If some Samba guru wants to tackle this, we'll attempt to
provide whatever additional information you need.
