• ssh问题_1


    昨天配置了虚拟机的ssh,可以相互连接,但是今天早上就不行了,遇到如下错误

    [slave1@hadoop ~]$ scp .ssh/id_rsa.pub master@hadoop.master:~/
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    The RSA host key for hadoop.master has changed,
    and the key for the corresponding IP address 192.168.62.130
    is unchanged. This could either mean that
    DNS SPOOFING is happening or the IP address for the host
    and its host key have changed at the same time.
    Offending key for IP in /home/slave1/.ssh/known_hosts:2
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @    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
    b9:01:69:34:98:01:9d:39:ed:a2:9a:2c:79:98:34:3d.
    Please contact your system administrator.
    Add correct host key in /home/slave1/.ssh/known_hosts to get rid of this message.
    Offending key in /home/slave1/.ssh/known_hosts:5
    RSA host key for hadoop.master has changed and you have requested strict checking.
    Host key verification failed.
    lost connection
    

     解决方法:#ssh-keygen  -R IP(这个IP就是你要去连接的IP)
