[SOLVED] No guest access to SMB on Voxel Orbi

[mith_y2k]

I hope people don't mind I have created a number of different posts here. I have a few different questions around Voxel's custom firmware for Orbi and in general I like short threads on specific topics so that other users can find answers easily instead of everyone posting on a giant thread.

I have an USB drive formatted in ext4 and the Orbi mounts it easily and started smbd. I was fiddling with smb.conf to add my own shares and noticed this:

  max protocol = SMB2

Any reason why not SMB3?

For reference, I'm asking this because I have a couple of clients running MacOS Catalina and I cannot login as Guest (login as root works fine). Finder doesn't ask me for credentials and when I try to force "Guest" using the smb:// syntax it still doesn't work. I found this article that says Catalina needs SMB3: https://www.techarp.com/software/macos-catalina-nas-failure/

Error message I get when trying to use "Guest"

I changed the max protocol to SMB3 and did a killall of smbd, but no luck for guest users.

Any suggestions to make the Guest user work is welcome

Some more update on this. I tried connecting with Kodi, but also requires credentials and the "Guest" user is not accepted. I tried with no password and with password "guest".

I increased the log level and this is what I see when I try to connect:

[2020/04/29 13:18:01.786091,  2] (check_ntlm_password)
  check_ntlm_password:  authentication for user [GUEST] -> [GUEST] -> [guest] succeeded
[2020/04/29 13:18:01.811448,  1] (make_connection_snum)
  macmini-16f85d (192.168.1.200) connect to service USB initially as user guest (uid=65534, gid=65534) (pid 9782)
[2020/04/29 13:18:01.813589,  1] (close_cnum)
  macmini-16f85d (192.168.1.200) closed connection to service USB

"macmini" is the client running Catalina and USB is the name of the share.

I did some more experimentation with no luck. Are users "guest" and "admin" working for anyone else? For me user root works fine, but admin and guest cannot login. I looked at the smbpasswd file and root and admin have the same password and parameters. In /etc/password admin has an x instead of the password, while root is the only user with a password. Any feedback or suggestions on how to fix this would be welcome. I would like to let all client read freely (guest account is perfect) and only root or admin can write.

Files in the entire mounted drive are like this:

drwxr-xr-x    4 root     root          4096 Apr 29 07:00 R_Drive

Thank you

And I finally solved the issue, it was the permissions on /mnt/sda1!

As per my last post I was looking to make sure that users had the appropriate read and write permissions. What I had not checked is that /mnt/sda1 itself had the right permissions. Once I gave it 755 the "guest" user started working. I knew it was some tiny detail.

"SMB3" protocol had nothing to do, so I changed the title of the thread.
