哈嘍哇,今天在訪問遠程服務器的時候,出現了一個小問題。
一、發現問題
問題如下圖代碼:
$ ssh [email protected]
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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 ECDSA key sent by the remote host is
SHA256:HDjXJvu0VYXWF+SKMZjSGn4FQmg/+w6eV9ljJvIXpx0.
Please contact your system administrator.
Add correct host key in /Users/wangdong/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/wangdong/.ssh/known_hosts:46
ECDSA host key for 108.61.163.242 has changed and you have requested strict checking.
Host key verification failed.
這裏面,有一句很關鍵。
ECDSA host key for 108.61.163.242 has changed and you have requested strict checking.
Host key verification failed.
一般這個問題,是你重置過你的服務器後。你再次想訪問會出現這個問題。
二、解決問題
解決問題也很簡單:
ssh-keygen -R 你要訪問的IP地址
例如:
ssh-keygen -R 108.61.163.242
貼個圖更直觀
好啦。很簡單的一個小問題。
搞技術,還是得一點一滴的慢慢積累。不積硅步無以至千里。
