linux中ssh登錄Permanently added (RSA) to the list of known hosts問題解決
用用戶名+密碼的方式登錄出現以下問題:
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]#
如果是直接輸入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).

[root@www]#
一、可以把~/.ssh/known_hosts清除
二、如果還是不行
修改/etc/ssh/sshd-config文件,將其中的PermitRootLogin no修改為yes,PubkeyAuthentication yes修改為no,AuthorizedKeysFile .ssh/authorized_keys前面加上#屏蔽掉,PasswordAuthentication no修改為yes就可以了。
三、如果還是有問題,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)?
1、這個是ssh安全認證是的一個RSA認證。此處必須選擇yes才能連接。
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,以後不會再出現提醒。
每次登陸只需要輸入密碼即可。
2、也可以不用輸入1中的yes,但是需要修改本機配置。
1
/etc/ssh/ssh_config 中的
2
# StrictHostKeyChecking ask 改成
3
StrictHostKeyChecking no
