Can't SSH into any of my Unraid servers


Recommended Posts

I had a weird issue today where I suddenly couldn't access my Unraid server from any device.  Ended up having to log into IPMI and restart the server manually.  So, I decided to configure SSH.  However, I can connect fine, but Unraid is disabling my keyboard inputs so I cannot enter a password.  Same behavior and syslog entry on both servers.  SSH is enabled, but is there something else I have to do in order to enable it?  Doesn't work from Putty on Windows or a Mac.

 

Postponed keyboard-interactive for root from 192.168.30.252 port 58839 ssh2 [preauth]

Doe anyone have anything I can try to unlock the SSH capability?  I assume that it is blocked and something needs to be done to unblock it, rather than it being a bug, but I don't know.  Seems like a pretty fundamental feature to not work out of the box (albeit disables in the GUI which makes sense).

So I've left SSH off for a few days.  Today, I turned it on again to try and test it again.  What I noticed is as soon as I turned it on, performance was significantly impacted and the server hung, and the dashboard wouldn't render.  When I looked in the syslog I can see that my server was absolutely flooded with Nginx events non-stop right after I turned it on.  I tried to include the diagnostics, but there are so many events it won't complete.  It won't even retrieve my folder directory in my media folder it's so busy.  Does anyone know what might be causing this?

Thousands upon thousands of these events...
