When system admins make sshd config changes to a remote server they do not logout of their working session before they confirm the changes work..
For example, if you are logged into a server and make changes to sshd, you do not log out of that session.
Code:
server:/var/www/ads# ssh me@remote.example.com
me@remove.example.com's password:
Last login: Thu May 9 08:14:30 2019 from 139.112.217.44
me@remote:~$ sudo -i
[sudo] password for me:
// make changes to ssh configation
remote:~# service sshd restart
You are still logged to the remote server.
Now try to ssh again from another terminal.
Or alternatively, you can run sshd on another port with another configuration file, for example on some (linux) systems;
I tried this solution, and I did not log out from session where I made the changes before opening a new session.
But it still does not work. I cannot ssh into the server anymore. "Network Error: Connection Refused" error.
