验证连接时 git 权限被拒绝(公钥)

Question

尝试执行以下操作时出现主题错误

$ ssh -T git@github.com
Permission denied (publickey).

.ssh权限

$ ls -al
total 33
drwxr-xr-x+ 1 MyUser AGL+Group(513)    0 Feb 27 16:53 .
drwxrwxrwt+ 1 MyUser AGL+Group(513)    0 Jan 10 16:12 ..
-rw-------  1 MyUser AGL+Group(513) 1667 Feb 28 18:01 .bash_history

-rwxr-xr-x  1 MyUser AGL+Group(513) 6054 Jan  9 20:45 .bashrc
-rw-r--r--  1 MyUser AGL+Group(513)   55 Feb 27 16:37 .gitconfig

-rwxr-xr-x  1 MyUser AGL+Group(513) 1236 Jan  9 20:45 .profile
drwx------+ 1 MyUser AGL+Group(513)    0 Feb 28 17:46 .ssh

我之前做了以下步骤

1. 生成 ssh key 并存储在 .ssh 文件夹中

2. 检查ssh代理

   $ ps aux |grep ssh<br/>
7236 1 7236 7236 ? 1138370 18:26:09 /usr/bin/ssh-agent

3. 通过设置将公钥 id_dsa.pub 添加到 github 帐户

我也尝试在这个论坛中遵循一些解决方案，但没有成功。我正在使用 Cygwin做这个

Answer 1

debug1: Skipping ssh-dss key /home/MyUser/.ssh/id_dsa for not in PubkeyAcceptedKeyTypes

您生成了 dsa key ，默认情况下不支持该 key 。你需要添加

PubkeyAcceptedKeyTypes +ssh-dss

进入您的 ~/.ssh/config，或者生成标准的 RSA key ，它可以正常工作。
