Hi everyone

I have a "Scan" share (exported, public) on my network to enable read/write access to scanned images/documents for all of my users. The scanner writes documents to this share without any issues. AFAIK the user and permissions are correct:

root@Unraid:/mnt/user/Scan# ls -l /mnt/user/Scan
lrwxrwxrwx 4 nobody users 7 Aug 24 13:41 /mnt/user/Scan -> ../tank/Scan/
root@Unraid:/mnt/user/Scan# ls -l /mnt/user/Scan/
total 1044
-rwxrw-rw- 1 nobody users 511573 Aug 24 13:11 24082025131150.pdf*
-rwxrw-rw- 1 nobody users 517497 Aug 24 13:41 24082025134119.pdf*
root@Unraid:/mnt/user/Scan#

But when I am connected to this share as a regular user from my Mac's Finder, I can read, but I can not write/delete files in this share?! According to the manual ("Public - The share is unsecured and all users have both read and write access to the contents of the share.") this should be possible if I understand correctly.

My goal is to have read/write access to all files and folders for all users on this share. What am I doing wrong?

Thanks a lot!

Post up the diagnostics file for this server in a new post in this thread.

Sure! Thanks for taking a look! 🙂

You don't have write permission here:

This is a standard problem with most Linux distributions. They no longer permit write permissions for group and other by default. Unraid requires -rw-rw-rw- permmissions for files and drwxrwxrwx for directories for SMB and NFS file sharing to work properly for all users (which include 'Guest' user!).

See here for Docker containers.

Ok. Thanks! I understand! But I did not change anything manually. I just created the shares and set them as exported and public?! So it's expected behavior, that public shares do not work "out of the box"?

chmod 777 für "Scan" and "Public" will fix the issue w/o further side effects?

FYI: The Tools -> New Permissions script did not work for me since /mnt/user/Public and /mnt/user/Scan are only Symlinks to /mnt/tank/Public and /mnt/tank/Scan accordingly. I had to fix it manually:

root@Unraid:~# chmod -R go-rwx,u-x,go+u /mnt/tank/Public/
root@Unraid:~# chmod -R go-rwx,u-x,go+u /mnt/tank/Scan/
root@Unraid:~# find /mnt/tank/Public/ -type d -exec chmod 777 {} \;
root@Unraid:~# find /mnt/tank/Scan/ -type d -exec chmod 777 {} \;

@Frank1940 THANK YOU SO MUCH 😊
