So I get this message sometimes when SSHing to my home machine from my work machine:
The authenticity of host '172.20.60.172 (172.20.60.172)' can't be established. RSA key fingerprint is 16:45:fb:04:f1:96:66:5a:6a:d8:e7:4c:f2:71:8c:ae. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '172.20.60.172' (RSA) to the list of known hosts.
I understand what the message means and the reason for it; I DO NOT want to disable it. My home machine's IP address changes frequently for reasons beyond my control (there is no way to give it a static IP, so don't ask).
Is there some key or fingerprint or something I can add to my local SSH config so that no matter what IP address I'm connecting to, if it sees that fingerprint (which never changes), it says "Ah, I know that fingerprint" and is okay with it? Or am I simply doomed to the immeasurable inconvenience of having to type "yes" once in a while?
