SSH客戶端提供命令刪除著名主持人

Question

在我的Ubuntu的服務器，當我即將通過SSH有不同的指紋來連接到已知的主體，它爲我提供的命令刪除從known_hosts文件中主機。 F.E. remove with: ssh-keygen -f "/home/rogier/.ssh/known_hosts" -R 192.168.1.4。

不幸的是，在OSX默認的SSH客戶端不提供此。是否有可能添加此行爲？

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 
18:7e:1f:24:5f:1d:52:b4:32:2c:ed:8e:9a:cc:0a:f7. 
Please contact your system administrator. 
Add correct host key in /home/rogier/.ssh/known_hosts to get rid of this message.

    remove with: ssh-keygen -f "/home/rogier/.ssh/known_hosts" -R 192.168.1.4 
ECDSA host key for 192.168.1.4 has changed and you have requested strict checking. 
Host key verification failed.

從brew中安裝最近的openssh。

或者剛剛從known_hosts文件中刪除提及的線，因爲該命令沒有做任何比這更神奇。
