May 21, 20251 yr I created an SMB share for use as a Time Machine backup. Got that working for backups, but...I connected to it from the Finder and tested creation of a folder and a file. The folder was created as mode 777, the file as as 766. With these permissions, if I also share it via NFS the files could be modified by anyone.I plan on creating other shares intended for both NFS and SMB but I want the permissions to keep the files at least unwritable by others. Is there any way to modify the SMB permissions used for file creation? Is there an Ideally, the users could use something like chmod or nfs4_setacl on an NFS client after creation to set exactly what they want if they need to share it.
May 21, 20251 yr There is another Sub-sub-forum called 'NFS' under the more general 'File Sharing Protocol Support' Sub-forum. You might find someone there who is more knowledgeable. (I would wait for about 48 hours before you create a post there.)As I see it, NFS is a bit of security nightmare because the user is the sole person responsible to getting things setup properly. I have done a bit googling in the past and there does not seem to be much help in the wider world with setting things up.BTW, 'Group' permissions of rw- and rwx for directories are absolutely necessary for a secured SMB setup to work. If one is using secure SMB practices, the 'Other' permissions (rw- and rwx) are really a little bit of security risk. However, since LimeTech has made a decision to still support Guest access to Unraid Shares, the rw- and rwx are still needed for 'Other'. Edited May 21, 20251 yr by Frank1940
