linux – SSH权限被拒绝(publickey)

我正在尝试从Ubuntu SSH到Debian.我已经有了RSA密钥;它与我使用 Git时使用的密钥相同.

我使用以下方法将密钥从Ubuntu复制到Debian：

ssh-copy-id -i ~/.ssh/id_rsa.pub root@ip-address

然后我在Debian上修改了sshd_config以包含以下内容：

RSAAuthentication yes

PubkeyAuthentication yes

PasswordAuthentication no

然后我重新开始了我的SSH服务.现在我尝试使用SSH从Ubuntu进入

ssh -v root@ip-addr

但我得到以下内容：

OpenSSH_6.6.1,OpenSSL 1.0.1f 6 Jan 2014

我基本上只想通过publickey身份验证强制SSH.

我已经阅读了与此主题相关的所有其他帖子,但这些帖子都不适合我.这就是为什么我把它创建为一个单独的帖子.

在sshd_config中将StrictModes从yes更改为no修复了问题.这样做安全吗？

这是服务器上SSH的日志：

May  5 18:23:55 lemaker sshd[2591]: Connection from 10.0.1.37 port 42748

解决方法

您不希望将.pub作为凭据提供.你想在你的最后使用你的私钥,所以你可能应该这样做

ssh -v -i ~/.ssh/id_rsa root@ip-addr

这是使用的deault键,所以你可以完全放弃-i标志

此外,如果您要通过ssh以root身份登录,请确保PermitRootLogin是
