The following error is prompted when you copy data using the scp command today:

@ 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
25: AB: 2e: 55: 30: 11: a0: 84: d8: 45: 2f: 5b: e2: 47: eb: 1e.
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: 1
RSA host key for 192.168.1.240 has changed and you have requested strict checking.
Host key verification failed.
Lost connection

At first, I thought it was a command error. After careful consideration, it turned out that the key verification error was, possibly because my account information had been changed.
 

Find the following ssh connection folder in the user's home directory:
1. cd ~ /. Ssh/
2. vi known_hosts
3. Find the key saving information consistent with the remote host ip address, directly Delete the line of information, and then save and exit
4. Reconnect and enter the password. The connection is successful.
