有许多类似的问题,例如SSH:“服务器拒绝我们的密钥”无故
但是,我已经完成了建议的检查,似乎无法让新用户通过ssh连接。这是我的过程;
useradd username
>passwd username
等...
在此之后,我已经检查了新用户的主目录权限,该权限=700
在其他帖子中建议。(~/.ssh/
和~/.ssh/authorized_keys
是700/600
分别地)
我用PuTTY创建一个新密钥,复制单行版本的公共密钥,然后将其粘贴到~/.ssh/authorized_keys
其余的公共密钥中。
然后,我尝试通过PuTTY(或使用相同密钥的stfp)连接,指定新的用户名和.ppk文件,但只是被告知服务器拒绝了我们的密钥。
过去,我已经成功为root用户添加了新密钥,但是添加新用户和密钥却无法正常工作。
我尝试在用户/ home / username目录中添加.ssh文件夹和authorized_keys文件,因为另一条建议无效。
我的sshd_config的相关部分是:
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile ~/.ssh/authorized_keys
PasswordAuthentication no
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
我没有允许或拒绝行
/ var / log / secure显示以下内容;
7月14日11:20:44 www sshd [18632]:收到与xx.xx.xx.xx的断开连接:14:无受支持的身份验证方法可用
7月14日11:22:08 www sshd [18629]:收到信号15;终止。
我对Linux命令行还很陌生,但是从我完成的所有谷歌搜索中,听起来好像我已经按照正确的顺序进行了操作,所以我不知道自己可能会缺少什么。

我不确定这到底意味着什么,但是如果有关系的话,也没有提到新用户的ssh密钥。
权限不仅很重要,而且用户和组也很重要。您应该能够从以下输出中注意到这一点:
ls -ldZ ~username/ ~username/.ssh ~username/.ssh/authorized_keys
这是常见的错误,尤其是如果您使用root
用户创建文件夹时。
