    linux中ssh登录Permanently added (RSA) to the list of known hosts问题解决

     
    用用户名+密码的方式登录出现以下问题:
    1
    [root@www]# ssh admin@xxx.xxx.xxx.xxx
    2
    The authenticity of host 'xxx.xxx.xxx.xxx can't be established.
    3
    RSA key fingerprint is f4:d0:1a:9c:09:65:78:71:25:33:79:c2:d5:aa:0b:c1.
    4
    Are you sure you want to continue connecting (yes/no)? no
    5
    Host key verification failed.
    6
    [root@www]#
    如果是直接输入yes
    1
    [root@www]# ssh admin@xxx.xxx.xxx.xx
    2
    The authenticity of host 'xxx.xxx.xxx.xxx' can't be established.
    3
    RSA key fingerprint is f4:d0:1a:9c:09:65:78:71:25:33:79:c2:d5:aa:0b:c1.
    4
    Are you sure you want to continue connecting (yes/no)? yes
    5
    Warning: Permanently added 'xxx.xxx.xxx.xxx' (RSA) to the list of known hosts.
    6
    Permission denied (publickey,gssapi-with-mic,password).
    7
    [root@www]#
    一、可以把~/.ssh/known_hosts清除
    二、如果还是不行
    修改/etc/ssh/sshd-config文件,将其中的PermitRootLogin no修改为yes,PubkeyAuthentication yes修改为no,AuthorizedKeysFile .ssh/authorized_keys前面加上#屏蔽掉,PasswordAuthentication no修改为yes就可以了。
    三、如果还是有问题,那颗一用下面的方式解决:
    用命令 ssh -l username hostname
    1
    Are you sure you want to continue connecting (yes/no)?
    1、这个是ssh安全认证是的一个RSA认证。此处必须选择yes才能连接。
    第一次yes后,他会询问你是否永久把这个RSA认证加入本地,选择yes后,以后不会再出现提醒。
    每次登陆只需要输入密码即可。
    2、也可以不用输入1中的yes,但是需要修改本机配置。
    1
        /etc/ssh/ssh_config 中的
    2
    #  StrictHostKeyChecking ask 改成
    3
       StrictHostKeyChecking no
