验证连接时拒绝 Git 权限(公钥)

Question

尝试执行以下操作时出现主题错误

$ ssh -T [e-mail]
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

drwx------+ 1 MyUser AGL+Group(513)    0 Feb 28 17:46 .ssh

在此之前，我做了以下步骤

1. 生成的 ssh 密钥并存储在 .ssh 文件夹中

2. 检查 ssh 代理

   $ ps aux |grep ssh
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

我也尝试了在这个论坛中遵循一些解决方案，但没有运气。我正在使用Cygwin来执行此操作

Answer 1

debug1：跳过 ssh-dss key/home/MyUser/.ssh/id_dsa for not in 公钥接受密钥类型

您生成了dsa密钥，默认情况下不支持该密钥。您需要添加

PubkeyAcceptedKeyTypes +ssh-dss

到您的~/.ssh/config，或者更确切地说是生成标准 RSA 密钥，可以正常工作。

Answer 2

因为您似乎使用的是DSA而不是默认的RSA。 您需要添加一行才能在SSH客户端配置中启用它。

以下是我从此链接中检索到的消息

默认情况下，RSA 支持处于打开状态，但 DSA/DSS 支持由以下各项启用：

在 ssh 客户端"配置"文件中添加行。

PubkeyAcceptedKeyTypes ssh-ed25519,ssh-rsa,ssh-dss,ecdsa-sha2

- 将配置文件命名为"config"，并将其放在 windows 中的用户主目录/.ssh 中。 /users/myname/.ssh/config

in the current build, the client config file is to be named ssh_config instead of "config"

sshd 服务器端还应sshd_config文件中具有以下条目： PubkeyAcceptKeyTypes ssh-ed25519，ssh-rsa，ssh-dss，ecdsa-sha2 进行这些更改后重新启动 SSH 服务器
