ssh连接错误:WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

SSH连接服务器时,经常会出现如下错误:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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 the RSA host key has just been changed.
Please contact your system administrator.
Add correct host key in /home/hogehoge/.ssh/known_hosts to get rid of this message.
RSA host key for 192.168.0.1 has changed and you have requested strict checking.

这个错误好像是说/.ssh/known_hosts中的key有问题,所以只要将该文件中的相关key删掉,重新连接就可以了.
