  • linux之 ssh连接服务器,WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

    [root@zk01 ~]# ssh localhost
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ 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 a host key has just been changed.
    The fingerprint for the ECDSA key sent by the remote host is
    SHA256:r86jc/Vu8phhiKKDSntetfkmksjQ606ZlUP8XNYe44U.
    Please contact your system administrator.
    Add correct host key in /root/.ssh/known_hosts to get rid of this message.
    Offending ECDSA key in /root/.ssh/known_hosts:10
    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,keyboard-interactive).

    说明: Add correct host key in /root/.ssh/known_hosts to get rid of this message.  重点在这句话

    分析: ssh登录过某机器后,因某机器有变动(更换ip等),再次登录不了,报错!!!

    解决过程:

    [root@zk01 ~]# mv /root/.ssh/known_hosts /root/.ssh/known_hosts.bak

    [root@zk01 ~]# ssh -o StrictHostKeyChecking=no 172.16.38.130
    Warning: Permanently added '172.16.38.130' (ECDSA) to the list of known hosts.
    root@172.16.38.130's password:
    Last login: Sun Oct 1 12:02:21 2017 from 172.16.74.104

    [root@zk01 ~]# ssh localhost      ## 输入密码,OK!
    Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.
    root@localhost's password:
    Last login: Sun Oct 1 12:04:59 2017 from zk01
