【问题描述】：
我正在尝试使用 cygwin+ssh 连接我的远程 linux 服务器，但身份验证失败且没有明显原因。我已经成功设置了另一个到 github 的连接，并且我遵循了相同的过程，这就是我在这里停下来的原因
$ ssh -v finxxx@xxx.79.xxx.29

我已经做了标准的东西，但我无法解决问题。这些是我用来生成私钥/公钥的命令。然后我将公钥复制到服务器
$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/xxxtta/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/xxxtta/.ssh/id_dsa.
Your public key has been saved in /home/xxxtta/.ssh/id_dsa.pub
感谢您的帮助
编辑： 我已经使用 MINGW 进行了相同的程序并且它可以工作（我能够连接）。我的系统中的 cygwin 肯定有问题
【问题讨论】：
-
您是否将您的 id_dsa.pub 添加到远程服务器上的
~/.ssh/authorized_keys？ -
是的，我已经复制了远程服务器上authorized_keys下的公钥
-
我知道这已经有好几年了，但如果知道在您的具体情况下解决方案是什么会很有趣！
