Thanks a lot for the information. You mentioned AWS console, that's not service-specific right? I haven't used AWS before. At any rate, lots too look up/researc

In that case, from an existing client with the SSH host key installed, or with your VPS provider's login shell system (if any), read the files '/etc/ssh/ssh_host_$ALGO_key.pub'. Each of these files will yield a line like this: ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBA4Ljuxwb9ss74agSmMRlBZdnIwMHprWIZ3Ts3G+hxnMmcQxeMAWoA4YXZwbrpQulFjDhjGqQoAGF+MKWXBpaeU= root@ip-172-31-17-215 These are all different hostkeys that the server might give to clients, depending on their mutually-agreed signature algorithm. This is in the same format as a line in the known-hosts file; all you need to do is replace that last bit (in my example, root@ip-172-31-17-215) with the hostname by which you log in (e.g. someserver.example.com). Once you've done that, append the results to the known_hosts file, either for your user account (~/.ssh/known_hosts) or system-wide (/etc/ssh/ssh_known_hosts). tl;dr: replacing HOSTNAME with the hostname by which you access the server, run the following command on your server and append its output to ~/.ssh/known_hosts on new clients: cat /etc/ssh/ssh_host_*_key.pub | awk '$3="HOSTNAME"'

  Thanks a lot. Right now I just use PuTTY, possibly SSH by command line (OS terminal). I'm not sure what I would put for the hostname that you mentioned (some domain) I imagine this will come after you do the out-of-bandwidth access thing which at the moment I just have one server but I think you can do it on the same server "on another bandwidth" yeah. I'm still not 100% but thank you for this.

Any kind of direct console access can be used (which many VPS providers offer).
