linux中ssh登陸Permanently added (RSA) to the list of known hosts問題解決

 

用用戶名＋密碼的方式登陸出現如下問題：

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]#

若是是直接輸入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]#

1、能夠把~/.ssh/known_hosts清除

2、若是仍是不行

修改/etc/ssh/sshd-config文件，將其中的PermitRootLogin no修改成yes，PubkeyAuthentication yes修改成no，AuthorizedKeysFile .ssh/authorized_keys前面加上#屏蔽掉，PasswordAuthentication no修改成yes就能夠了。

3、若是仍是有問題，那顆一用下面的方式解決：

用命令 ssh -l username hostname

1

Are you sure you want to continue connecting (yes/no)?

一、這個是ssh安全認證是的一個RSA認證。此處必須選擇yes才能鏈接。

第一次yes後，他會詢問你是否永久把這個RSA認證加入本地，選擇yes後，之後不會再出現提醒。

每次登錄只須要輸入密碼便可。

二、也能夠不用輸入1中的yes，可是須要修改本機配置。

1

    /etc/ssh/ssh_config 中的

2

#  StrictHostKeyChecking ask 改爲

3

   StrictHostKeyChecking no
