Hello.
I am having problems copying files from a WinNT 4.0 box
to a Red Hat Linux 7.0 computer running Samba 2.2.2 (I've
seen this problem with 2.2.1a also). I downloaded 2.2.2
from samba.org and built/installed it myself.
I've checked the FAQ at samba.org and searched the
mailing list archives at marc.theaimsgroup.com; I've
also done several Google searches. I've seen a couple
of mentions of the problem in different mailing lists,
but I've seen no answers with solutions.
If I drag-and-drop a file in Windows Explorer from a
directory on the NT box to a share on the Linux box,
I intermittantly receive the error message "Cannot
copy [file]: Access is denied."
If I check the Samba logfile (log level 4), I see this:
[2001/12/04 04:58:29, 4] smbd/open.c:open_file_shared(784)
calling open_file with flags=0x1 flags2=0x240 mode=0764

[2001/12/04 04:58:29, 2] smbd/close.c:close_normal_file(206)
kasper closed file tmp/schiff16.bin (numopen=1)
[2001/12/04 04:58:29, 3] smbd/error.c:error_packet(99)

error packet at smbd/nttrans.c(1405) cmd=160 (SMBnttrans) eclass=1
ecode=12
I end up with a zero-length file named "schiff16.bin" in
the destination directory. The basic problem seems to be
that the file is opened for writing and immediately closed,
resulting in the zero-length file.
This is an intermittant problem which seems to become worse
with larger files. I'm wondering if it's a timeout problem;
it doesn't *appear* to be a permission problem, because it
doesn't always happen. Looking in the source (open.c, around
line 791), I see this comment:
* Deal with the race condition where two smbd's detect the file doesn't
* exist and do the create at the same time[ etc ...]
Is it possible that this race condition hasn't been fully debugged?
I've attached the contents of my smb.conf file. I'm trying to write
the file to a subdirectory in the main "yoyodyne" share.
