I have a server that I need to connect to sometimes. It has a public IP, but the IP is renewed quite often. To combat that, I have a script that will update a DNS record to map ssh.myurl.com to my new IP.
This setup works, but once the IP changes, I get the error:
WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
Then I have to delete the key from my client, using ssh-keygen -R ssh.myurl.com, and it works again.
But this seems redundant, as I can't really see how this adds any security. Can I configure this setup so that it always trusts this connection?
The setup is using ProxyJump if that would change anything.
