Can't change permissions on file copy (samba).

Hello!
I've recently installed samba at debian host. And configured samba with full access for anybody without login/password.

At the server side shared partition type is ntfs, fstab options for share:

Code:

/dev/sda2	/media/servstor	ntfs-3g	umask=0		0	0

and here smb.conf:

Code:

[global]
       workgroup = WORKGROUP
       hosts allow = 192.168.
       interfaces = all
       log file = /var/log/samba/log.%m
       max log size = 1000
       syslog = 0
       guest account = nobody
       security = share
       unix charset = UTF-8

[share]
       path = /media/servstor
       comment = share
       printable = no
       writable = yes
       guest ok = yes
       create mask = 0777
       directory mask = 0777

At the linux client side (gentoo):

Code:

echo <pass> | sudo -S mount -t cifs //192.168.1.5/share /media/share -o workgroup=WORKGROUP,ip=192.168.1.5

I can mount share and can create, delete and copy files and folders. All fine except one thing: when I copy files to share, I get a message 'Can't change permissions for file <filename>' for each file that was copied. And I have to click 'OK' for each message. No problem on copying one or two files. But copy a folder with a hundreds of files - it is a really asspain

I read a tons of manuals and tried billions mounting options, rebuilt kernel with CIFS options, played with polkit settings, but nothing helps.
Can anyone help me?
Thanks in advance.

P.S.
I think server's configuration is OK because I have no these messages when I copying files to server from other desktop (with Arch installed).

If the file system is NTFS then try to remove these entries from config

Code:

create mask = 0777
directory mask = 0777

and dont forget to restart samba after changes.

Removed and restarted, doesn't helps.
I am sure that server's config is OK, because Arch works with this share fine.

Post ls -al of samba shared dir with:
- file created locally on server
- file copied from remote machine

Send also ls -al of shared dir (itself).

Files that was created at server has this attributes:

Code:

echo "aaa" > /media/servstor/server-test-file
ls -al /media/servstor/server-test-file
-rwxrwxrwx 1 root root 4 Nov 20 16:54 /media/servstor/server-test-file

File created at client:

Code:

echo "aaa" > client-test-file
ls -al client-test-file 
-rw-r--r-- 1 user user 4 Nov 20 16:55 client-test-file

After copy to share file's attributes changed:

Code:

ls -al /media/servstor/client-test-file
-rwxrwxrwx 1 root root 4 Nov 20 16:55 /media/servstor/client-test-file

attributes and owner was changed from 'rw-r--r-- 1 user user' to 'rwxrwxrwx 1 root root'

server-side mount directory has 'drwxrwxrwx 1 root root' attributes.

In your global config there is set option:

Code:

guest account = nobody

change it to "root" (its possibly unsafe)

The right solution would be to set up this as following but since you are running it on NTFS it may not work (I dont have a place now to check it)

Code:

chown -R nobody:nbody /media/servstor

chown does nothing.
'guest account = root' works only for root. Regular user still gets messages on file copy.
Also I tried 'guest account = <username>' - this also does nothing.
