SCP Error

Linux version: Red Hat Enterprise Linux AS release 4 (Nahant Update 5)

两台机器的OS都由我安装,一台机器的scp可用,另一台机器的scp不可,使用scp时报如下错误:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@ 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.

The fingerprint for the RSA key sent by the remote host is

e4:7f:e0:89:b3:f8:f8:09:99:06:fb:c2:84:f9:08:e9.

Please contact your system administrator.

Add correct host key in /home/oracle/.ssh/known_hosts to get rid of this message.

Offending key in /home/oracle/.ssh/known_hosts:1

RSA host key for 10.x.x.xhas changed and you have requested strict checking.

Host key verification failed.

试着把known_hosts重命名,再次运行scp,OK.发现scp会生一个新的known_hosts.

怀疑在运行scp安全验证是输入了no导致此错误的发生,经实验怀疑是不对的.
