Question

我知道这是一个很常见的问题，但我相信我的情况并非常见。

我有一个ubuntu AWS EC2实例，我使用Mac上的私钥访问该实例。

我希望在工作时访问，因此我将密钥放入我的Dropbox帐户并将其下载到我的工作（Windows）电脑上并放在C:/Users/[myusername]/.ssh目录中。我也是chmod 600＆＃39; d。

我使用Git shell作为ssh，因为它有SSH，我现在不想安装putty。

所以我运行命令

C:\Users\[myusername]\.ssh> ssh -v -i .\key_pair.pem ubuntu@[redacted].compute.amazonaws.com

（当然使用正确的dns名称。）

这是输出：

OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007

我确定我使用的密钥是正确的，因为它适用于我的Mac。还有什么我做错了吗？

编辑：我注意到调试输出提到：

debug1: Offering public key: C:\\Users\\[myusername]\\.ssh\\github_rsa

它提供不相关的公钥的事实会影响身份验证吗？

Answer 1

.\key_pair.pem 错了。

使用 ./key_pair.pem 代替Git bash（无论你是否在Windows上都没关系）

无法使用发送给自己的私钥连接到AWS EC2（权限被拒绝：公钥）
