    1 scp报错:REMOTE HOST IDENTIFICATION HAS CHANGED!
    [root@xx ~]# scp yum-3.4.3.tar.gz 10.xx.xx.12:/root
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @    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
    xxxxxxxxx.
    Please contact your system administrator.
    Add correct host key in /root/.ssh/known_hosts to get rid of this message.
    Offending key in /root/.ssh/known_hosts:20
    RSA host key for 10.xx.xx.12 has changed and you have requested strict checking.
    Host key verification failed.
    lost connection
    [root@cache-2 ~]# 


    2, google,RSA报错。要不重建RSA Key,要么就删除Client的known_hosts中相应的ip信息记录,这里选择后一种。


    3。 先找到known_hosts的路径
    [root@xx tmp]# find / -name known_hosts
    /root/.ssh/known_hosts

    4,先备份系统文件,在改动
    [root@cache-2 tmp]# 
    [root@cache-2 tmp]# 
    [root@cache-2 tmp]# cp /root/.ssh/known_hosts /root/.ssh/bak.20140526.known_hosts
    [root@cache-2 tmp]# 
    [root@cache-2 tmp]# vim /root/.ssh/known_hosts

    找到
    10.xx.xx.12 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA0ifRyEQAdoH+1GFnFv+c+vzQ8tCIxREuAff57heXPt0sJpTNaJaB/RsFV4yKmBdyrOggdmxEdm1G851Ni+m6OW7fzUdZnqfQaF/pAmu0fyhVGWa0rjNG6IVyrrFEMKxn8cgLSLfxSwfC8aM6y30sCBAeUy6xTUI2ImOMk9e9UR6vBSENweZUj53CqfIg/NfqL1GozShiKF4+Wt3zuQDVTMNbPeB3Yyp3U+v4TLnAaYgA5fjGGZmN0QUcI//toZpyVVWmFnxXUKhqFzmHDPNrlfgq2nCqXCdYUVCZHty7hupDY0YkzUt12VR5Ifdg2BpvHZki5cPZL/046laeIX1DGw==
    删除就可以。




    5。再运行scp命令。输入密码,传输成功。
    [root@xx ~]# scp yum-3.4.3.tar.gz 10.xx.xx.12:/root
    root@10.xx.1x.12's password: 
    yum-3.4.3.tar.gz                                                                                                                                             100% 1114KB   1.1MB/s   00:00    
    [root@xx ~]#
