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

https://www.cnblogs.com/houji/p/5294491.html

 

用用户名+密码的方式登录出现以下问题:

1

[root@www]# ssh [email protected]

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 [email protected]

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
