Changed routers, new gateway, how do I update my SSH keys properly?

I just changed routers and went from gateway 192.168.2.xxx -> 192.168.0.xxx

I set up the new static/reserved IPs for all my machines (3: desktop, laptop, server) and amended the `/etc/hosts`files accordingly. Everything works, I can ssh between them, but I get this warning when I log in via ssh:

Code:

ECDSA host key for IP address '192.168.0.xxx' not in list of known hosts.

I'm pretty sure when I first connected it said that it was added to the list of known_hosts, so I don't really know what I missed.

Why don't you look in known_hosts? The file is at $HOME/.ssh/known_hosts.

You may have inadvertently set up your ssh to not adding new hosts to known_hosts. There is an option for that in the ssh_config file.
