linux - 无法通过 ubuntu 中的配置文件将 ssh 连接到 ec2。权限被拒绝(publickey、gssapi-keyex、gssapi-with-mic)

Question

无法通过 Ubuntu 连接到 SSH。但在 MAC 上运行良好。

我的配置文件

Host testserver
User ubuntu
IdentityFile '/home/kavin/.ssh/AnotherKey.pem' 
HostName ec2-54-201-xxx-xxx.us-west-2.compute.amazonaws.com

通过 SSH 连接

$ ssh testserver

这与我在 Mac 和 Ubuntu 上所做的相同。它在 Mac 中完美运行，但在 Ubuntu 中会抛出错误 权限被拒绝 (publickey,gssapi-keyex,gssapi-with-mic)。

现在我尝试了另一种方式ssh -i '/home/kavin/.ssh/AnotherKey.pem' ec2-user@54.201.xxx.xxx

这在 Mac 和 Ubuntu 中都可以正常工作。

你能告诉我哪里出错了吗

这些是 $ ssh testserver -v 的日志
