samba - Jun 2008 - Create masks set to 770 yet new files created as 750

Hello All.

Samba ver 3.0.25b-1.1.cc

Simple problem thats happening on two different servers.

Samba is a PDC, users are creating files via windows.

My goal is to make each and every file rwxrwx--- . 

They are being created as rwxrw----

The masks on each share is :

browseable = yes
writeable = yes
create mask = 2770
security mask = 2770
directory mask = 2770
directory security mask = 2770

I've also performed a chmod -R 2770 on the entire share dir.

if I add 

force create mode = 2770
force directory mode = 2770

to each share the new files are created as 770. 

Is this nessesary? I thought the create masks would be sufficient.

I dont want to use too many unessesary options on each share.

If anyone can assist cleaning it up that would be very helpful.

Thanks

Yes it is. From the smb.conf man page: 

          [The] resulting  UNIX  mode  is then bit-wise 'AND'ed with 
this parameter.
          This parameter may be thought of as a bit-wise  MASK  for  
the  UNIX
          modes of a file. **Any bit not set here will be removed from 
the modes
          set on a file when it is created.**

So the masks define which bits CAN be set, the force modes define which 
bits WILL be set.

"mask" and "mode" are identical.

"create mask" and "directory mask" make an "AND",
in your case they
delete the "other" bits.

"force xyz mask" makes an "OR", it sets every defined bit.

Viele Gruesse!
