SSH connection failed: host key verification failed

Some servers have recently been replaced, but some servers have not been replaced. I was rejected when I logged on to other servers via SSH on the original server.

Run: ssh xxx. XXX

Result:

@ Warning: remote host identification has changed! @

It is possible that someone is doing something nasty!
Someone cocould be eavesdropping on you right now (man-in-the-middle attack )!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
A1: EE: 9e: 76: 32: AB: 79: 83: 21: C1: D1: EB: 35: 44: Fe: B4.
Please contact your system administrator.
Add correct host key in/root/. Ssh/known_hosts to get rid of this message.
Offending key in/root/. Ssh/known_hosts: 13
RSA host key for 10.0.0.10 has changed and you have requested strict checking.
Host key verification failed.

 

The solution is to directly Delete the/root/. Ssh/known_hosts file.
