  • 好记心不如烂笔头,ssh登录 The authenticity of host 192.168.0.xxx can't be established. 的问题

    用ssh登录一个机器(换过ip地址),提示输入yes后,屏幕不断出现y,仅仅有按ctrl + c结束

    错误是:The authenticity of host 192.168.0.xxx can't be established.

    曾经和同事碰到过这个问题,攻克了,没有记录,这次又碰到了不知道怎么处理,还好有QQ聊天记录,查找到一下,找到解决方式:

    运行ssh  -o StrictHostKeyChecking=no  192.168.0.xxx 就OK

    网址是:

    记一下,防止又忘记了,又快到3点了,无数个不眠之夜啊。

    某天机器又改IP了,ssh后,报:

    mmt@FS01:~$ ssh  -o StrictHostKeyChecking=no  192.168.0.130
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @    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
    fe:d6:f8:59:03:a5:de:e8:29:ef:3b:26:6e:3d:1d:4b.
    Please contact your system administrator.
    Add correct host key in /home/mmt/.ssh/known_hosts to get rid of this message.
    Offending key in /home/mmt/.ssh/known_hosts:38
    Password authentication is disabled to avoid man-in-the-middle attacks.
    Keyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.
    Permission denied (publickey,password).

     注意这句

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

    运行:

    mv  /home/mmt/.ssh/known_hosts known_hosts.bak

    再连:

    ssh  -o StrictHostKeyChecking=no  192.168.0.130


    OK了!
