Question

我正在尝试使用cygwin + ssh连接我的远程linux服务器但是身份验证失败没有明显的原因。我成功地为github建立了另一个连接，我也遵循了相同的过程，这就是为什么我在这里停止了

$ ssh -v finxxx@xxx.79.xxx.29

我已经制作了标准的东西，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

谢谢你的帮助

修改我使用MINGW做了相同的程序，它工作（我能够连接）。在我的系统中，cygwin肯定出现了问题

Answer 1

问题可能在于用户名。如果您远程登录，则用户名区分大小写。您必须完全按照Windows中的定义编写用户名。

Answer 2

将id_dsa.pub复制到远程服务器。

# scp .ssh/id_dsa.pub dude@remotemachine

在远程服务器上：

# cat id_dsa.pub >> ~/.ssh/authorized_keys

Answer 3

您可以尝试使用-vvv而不是-v来增加详细程度另外，请检查是否正确设置了文件权限。见Adding public key to ~/.ssh/authorized_keys does not log me in automatically

使用cygwin连接ssh
