Hi các bạn, chắc hẳn các bạn nào đăng nhập vào ssh root server hay VPS đã gặp qua sự cố như dưới đây:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
3c:a7:bb:cc:00:e5:9a:a0:c2:2d:b4:aa:28:e3:61:f7.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending RSA key in /root/.ssh/known_hosts:2
RSA host key for 111.111.111.11 has changed and you have requested strict checking.
Host key verification failed.
Các bạn thử làm theo cách giống mình bên dưới:
- # ssh-keygen -R 111.111.111.11
- yes
- Sau đó thử lại bằng:
- # ssh root@111.111.111.11
- Nhập password.
