I have run chmod etc. This is 6.11.5 so the directories are sym-linked to the usb. I have everything set up and working across my other homelab parts and unirad used to work. It has suddenly stopped. Diag attached.

docgyvers SSH Plugin solve my issues, Not fully sure why but I'm not going to look a gift horse in the mouth.

Just writing to confirm the experience of DuzAwe -- Docgyvers SSH plugin solves the issue of not being able to ssh into unraid v6.11.1 using key exchange.

 

I have a number of scripts that rely upon being able to ssh into unraid without a password. These worked fine until upgrading unraid. I tried all the fixes I could find in these forums without success. The unraid syslog.txt gave the error:

 

Authentication refused: bad ownership or modes for directory /

 

Weird, since I had already set permissions to 700 for the .ssh directory and 640 for the .ssh/authorized_keys directory as part of my troubleshooting the issue.

 

Anyhow, the plugin places an SSH icon in Settings > Network Services. Just open it and hit "Apply" without changing anything. Now everything just works.

 

 

I'm having this same problem and the plugin isn't doing anything for me. Running 6.12.8, just started happening for no apparent reason... Can anyone help?

Had the same issue after an upgrade to 6.12.13 and plugin updates. Not sure if either of those caused the issue but found that / was owned by a shares user instead of root.

I no longer needed the user and deleted it. You'll likely be able to also run

chown root:root /

I think I fixed the problem by way of a reboot. I don't recall exactly.

I faced that issue on one of my unraid servers this morning as well. On that specific server I am using Unraid 7.0 and out of the sudden it was not accepting any ssh key logins anymore. Unraid was logging:

 

Authentication refused: bad ownership or modes for directory /

 

I am using this specific ssh setup since years without any problems.

After a reboot it was fine again.

Same for me! Been using this key forever and all of sudden can't login. Rebooting in a few to see if that sovled it

-edit-

Can confirm, reboot solved this.
