NFS file permissions for new files

Posted on 2008-10-28
Last Modified: 2013-12-02
I have a file server that shares with Windows clients via SMB and Linux clients via NFS. When a Windows user creates a new file on the share it uses group/user permissions for new files that are set in the smb.conf file, when a Linux/NFS client creates a new file it is given a different set of permissions. Is there any way to set what group/user permissions are used for NFS in a similar way as is done with Samba?

My NFS shares are exported using:


All users and groups for Windows and Linux come from an Active Directory.

did you consider using umask ?

... or let your Linux clients do smbmount ?

I figured that I'd have to add a mask somewhere, the question should probably have been worded more like "what configuration (file) do I add a mask to?"

And no, I prefer to use NFS for Linux clients.

You should modify the user's profiles on the client side. Which file to modify depends on the shell used, in ksh it's e.g. ~ /.profile , in csh e.g. ~/..cshrc and ~/.login,  in bash e.g. ~/.bashrc, ~/.profile, ~/.bash_login or ~/.bash_profile.
The 'env' method works as well.
Of course you could change the umask globally in /etc/profile.
I wouldn't recommend that.

To ~/.bashrc I added:
  umask 002
to bring the default permissions from 666 to 664.
