Today, I needed to setup ssh on a newly installed Ubuntu machine. Setting up ssh itself was straight forward

• install openssh-server
• start it via systemctl
• enable the port in the firewall

But when I tried connecting it from other machine, I got the following error:

Received disconnect from 192.168.1.110 port 22:2: Too many authentication failures ¹

When I tried to get help, GenAI focused on Too many authentication part of the error, and gave me suggestions to change server to allow more attempts.
