Samba file transfer creates zone identifier files...

[raguiarunav]

I agree with what someone said above about fixing it would useful for Suse. I think the real issue is: why samba can't read/write/delete these files? And maybe a part of this issue or another one related with it is: why the update to Samba 3.2 caused this? (if it is the real cause...)
Thanks

This is from the SAMBA LIST with the problem and solution. It might help
some of you.

I did not copy the patch, but using the above parameter might help.

Glad it helped. I had not noticed this on our servers until after this
thread was posted (if you don't look, you won't see it). We are running
Samba 3.2.0, but on OpenSuse 10.2, and this also fixed it for us. This
problem should be fixed in 3.2.1.

This fix with vfs objects = streams_xattr didn't work correctly for me. When I setup it, i didn's see shte existing Identifier files, but I can't copy downloaded from the internet file to the server. It says Network Is Busy

Samba 3.2.1 has been released. It seems to solve the zone file problem without
the vfs objects parameter. We have not had the chance for extensive testing of
this last fact, but so far so good. The last time I looked The Suse RPMs were
not yet on the Mirrors, but they should be there as soon as the Mirrors sync.

Yeah, I update to samba 3.2.1 and the problem with Zone Files disappear. I hope the new version will work fine now

Good News. I have no idea why the work around did not help you.

I use XP and Linux (many versions RH9 Suse10.3 Suse 11.0 Suse 11.1b5).
I download files with Firefox on my XP system, and since I have set Windows Explorer to show hidden files, I DO see the Zone Identifier files. These files started showing up with Firefox 3.x.

I do not remember getting this on Suse 11.0 with Firefox, so I suspect it's not a Firefox thing therefore, and I can find no settings for it in the options.

It seems reasonable that therefore that it's a Windows thing of some kind, triggered by the latest Firefox - though no obvious settings. "Fixing" it in Samba is therefore a mistake - the problem is most people don't have their file manager on Windows set to "Show Hidden Files".

Reading around on the Internet it seems likely that Firefox 3.x "improved" their file downloads by running them through the Microsoft "Attachment Execution Services (see IAttachmentExecute)" which (imperfectly) prevents execution of downloaded files. This matches the action the IE (Internet Explorer) takes with downloaded files.

See
F-Secure Computer Virus Information Pages: Zone.Identifier
File Extension .IDENTIFIER Details
Persistent Zone Identifier Object ()

So far there doesn't appear to be a good way to prevent creation of these things.

Upgrade Samba to the current stable release. RPMs can be found here:
//ftp.suse.com/pub/projects/samba/3.0/
This was a bug in 3.2.0 (distributed with 11.0) and repaired in Samba 3.2.1.
The current stable release is 3.2.4.
