"their offer: ssh-rsa"

Just upgraded to Ventura and the huge majority of Indigo is working just fine, including most of the Unify plugin.

However, my log is filled with:

Code: Select all

 uniFiAP Error                   testServerIf ssh connection to server failed, cmd: /usr/bin/expect '/Library/Application Support/Perceptive Automation/Indigo 2022.2/Plugins/uniFiAP.indigoPlugin/Contents/Server Plugin/test.exp' 'REDACTEDuser' 'REDACTEDPWD' 192.168.0.1
   uniFiAP Error                   getMessages: (1 - test connect)  error for UDdict, ip#: 192.168.0.1, prompt:'# '; wrong ip/ password or system down or ssh timed out or ..?

When I try to ssh into the dream machine from the command line to test the known good username and password, I now get::

Code: Select all

% ssh root@192.168.0.1
Unable to negotiate with 192.168.0.1 port 22: no matching host key type found. Their offer: ssh-rsa


Is this just some problem with saved keys? Did Ventura change default SSH configurations? Should I just remove any .pem files associated with the UDM?

Maybe Ventura has a stricter SSH policy now? See https://blog.awill.me/2021-10-16/sshing-into-unifi/

OK, yes it seems Unifi uses an old version of SSH and Ventura doesn't like to talk to it. I followed the instructions at https://superuser.com/questions/364304/ ... sh-on-os-x and at the other link above to add rsa back to OSX's allowed algorithms and the errors are gone.

could you try ssh with option: -o StrictHostKeyChecking=no
so:

Code: Select all

ssh yourUserId@192.168.1.x  -o StrictHostKeyChecking=no

could you check if that works?

I am also running ventura(13.3.1) , no problems here with ssh to unifi (BusyBox v1.23.2)

I'm running UniFi OS UDM 1.12.22 but I'm about to run some updates.

I'm loathe to mess with my ssh setup since it's working as is, but if it breaks again after the update I'll try it.
