[Samba] More Info: Mac permission problems after Debian update

Thu Feb 12 07:45:14 GMT 2004

There seems to be a few people having this problem, but not much response.
I've dug into the logs, and while I don't know exactly what I am looking
at, I think I may have found something that may make sense to someone.

A short recap. Samba was working fine, until I did a Debian security
update, which upgraded my Samba to 2.2.8a. Now, I can create files on a
mounted Samba share in a console, but not in the finder, I get the message
'The operation cannot be completed because you do not have sufficient
privileges for "dilbert030923.gif"', which is the name of the file being
copied. From what I see in the logs, I think the privileges message is
off.

Once I dismiss the dialog, there is nothing in the directory I am copying
to, but before I dismiss, I find two files: a zero length
dilbert030923.gif, and a 82 byte ._dilbert030923.gif.  One of the files
being non-zero length is a second clue that the privileges message may be
bogus.

Because of the error messages below, I tried turning off posix locking,
and things seem to be working now. So I guess my question has become, will
running without posix locking harm anything? And, I don't believe I
changed that setting during the upgrade. I suppose the default could have
changed, but is there something more sinister going on in the logs below?

I mounted the share, changed logging to level 10, and tried to copy a
file.

Looking in the log, I can see it create the 82 byte file, and
open/read/close it a few times. There are a few of these:

The size of the file being copied is 17093 bytes.

Do the error messages in this log snippet provide any real clues?

Thank you,
