How to remove RSA Key Fingerprint?

Question?

I’d like to remove the following RSA key fingerprint from my DirectAdmin vps because I no longer have an ecommerce website that required it.

This is a message I got from my vps: 

Code:

The authenticity of host ’128.31.301.40 (128.31.301.40)’ can’t be established.
RSA key fingerprint is 4d:05:3e:5b:ea:90:7a:be:6e:55:bc:ba:12:02:06:69.

Answer:

Just remove it from ~/.ssh/known_hosts or empty the file. As soon as you try to connect a host again, the file will be created with correct data.
