ssh remote host identification has changed

Question

I\'ve reinstalled my server and I am getting these messages:

[user@hostname ~]$ ssh root@pong
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Answer 1

Use

ssh-keygen -R [hostname]

Example with an ip address/hostname would be:

ssh-keygen -R 168.9.9.2

This will update the offending of your host from the known_hosts. You can also provide the path of the known_hosts with -f flag.
