I'm hoping you guys can help. I've been searching for along time with reading the information on noip.com and couldn't figure out anything.
I've set up an SSH server on a home computer. I changed the port # in sshd_config and forwarded my port number to the router. I can connect to my sever fine if I am on the same network as the server (using ssh -p port# firstname.lastname@example.org) and can connect fine from a different net work using (ssh -p12xx email@example.com).
I have setup an noip account and have attained a host-id "me.ddns.net". downloaded the noip-DUC updater to update my ip address. My question, when i tried to ssh -p port# me.ddsn.net (my host name on noip doesn't use the @ symbol), I got a error Permission Denied (public key). To be clear, I can still connect to my server fine using the private ip and the public ip, just not via the host name from noip. As I've mentioned, I do use ssh-keys and have disabled password prompt. Do I need to configure an ssh-key for noip or upload my ssh-keys to noip? I've only been messing with SSH for 24 hours and is very unexperienced. I appreciate everyone's advice.
