Can't use SSH keys Authentication refused: bad ownership or modes for directory /

[DuzAwe]

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.

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.
