If you want to know / list / print or even compare what is your ssh RSA key fingerprint, simply run the command below.
You can run this command as regular user or as root.
It is same folder for Debian / Fedora / CentOS / Ubuntu
The RSA key fingerprint is located at: /etc/ssh/ssh_host_rsa_key
And to print the ssh RSA key, type the command below :
ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key
So every time you make ssh connection, you have to make sure that the following match to your file, otherwise you might not be at your server (or the server that you think you are in 😐 )
