  • ssh 报错Host key verification failed 或Ubuntu connect to serve 失败

    ssh 报错Host key verification failed  或Ubuntu connect to serve 失败  通常是因为没有装ssh

    sudo apt-get install  openssh-server 就可以了,但是我这边是因为之前连上了,后面远程服务器改了密码,

    之前保存的密码验证失败,这时候就要把保存的密码删掉,哪里删掉???

    用Ubuntu connect to serve 就直接报错,用ssh就报下面的错,

    ssh xxx@xxx.xxx.xxx.xxx

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ 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
    xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    Please contact your system administrator.
    Add correct host key in /home/xxxxx/.ssh/known_hosts to get rid of this message.
    Offending ECDSA key in /home/xxxxxx/.ssh/known_hosts:23
    remove with: ssh-keygen -f "/home/xxxxx/.ssh/known_hosts" -R xxxx.xxxx.xxxx.xxxx
    ECDSA host key for xxxx.xxxx.xxxx.xxxx has changed and you have requested strict checking.
    Host key verification failed.

    其实,只要打开 /home/xxxxx/.ssh/known_hosts ,把23行的删掉就可以,那个是密钥保存的,之后远程登录重新输入新的密码就可以了
