I try to connect to ubiquiti gear with ssh but get the error in the log on the client side:
Exit before auth: No matching algo hostkey
in Netxms i get ssh connection not available.
if i connect with tools, connect, ssh, it asks me user and password and connects.
My goal is to have passwordless connection to ubiquiti devices...
Is there a howto ? I tried several times but no luck....
ssh connections in netxms are performed via agent that is running along with the server. You can try setting debug level 6 for that agent - one way is to stop it via systemctl:
systemctl stop nxagentd
and start in in foreyground:
nxagentd -D 6
Then try running configuration poll for your uniquiti node to see if ssh capability becomes yes. Or try adding a ssh DCI on that node and forcing poll for that DCI. Log of the above agent should have some lines about ssh.
