SSH - 服务器上的权限被拒绝（公钥）

Question

我正在尝试在 Hostgator 上的共享主机上使用 git，但在与 Github 建立连接时遇到问题。我已经在网上尝试了很多答案，但到目前为止没有任何改变。

这些是我为了实现这一目标而遵循的步骤（我使用了this github guide）：

在我的机器上，

1.我用ssh-keygen -t ed25519 -C "myemail@address.com"创建了一个新密钥

2.我保存到文件~/.ssh/remote_github.pub，文件没有 密码

3. 然后我跑了eval "$(ssh-agent -s)"

4.在我指定的~/.ssh/config 文件中

Host *
  Hostname IP-ADDRESS-OF-SERVER
  AddKeysToAgent yes
  IdentityFile ~/.ssh/remote_github
  IdentitiesOnly yes

5.我用pbcopy < ~/.ssh/remote_github.pub复制了公钥并将其保存到我的github帐户中

6. 然后我跑了ssh-copy-id -i ~/.ssh/remote_github.pub myuser@remoteserver

答案是

INFO: Source of key(s) to be installed: "/Users/mattiabombelli/.ssh/remote_github.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
mbombelli@192.254.233.200's password:

输入密码后：

Number of key(s) added:        1

Now try logging into the machine, with:   "ssh 'myuser@remoteserver'"
and check to make sure that only the key(s) you wanted were added.

检查服务器上的authorized_keys 文件，我看到存储在我的机器中的完全相同的公钥remote_github.pub*

7. 但此时，如果我尝试运行ssh -T -v git@github.com

这是我得到的：

Permission denied (publickey).

我还确保使用chmod 700 ~/.ssh 和chmod 600 ~/.ssh/authorized_keys 更改服务器上的权限，但答案始终是Permission denied (publickey).

我做错了什么？还是不见了？

谢谢。

*authorized_keys 文件还包含另一个 ssh-rsa 公钥。

Answer 1

首先，如果你的私钥没有密码，你就不需要任何与 ssh-agent 相关的东西。

第二，“他在服务器上的 authorized_keys 文件我看到存储在我的机器上的完全相同的公钥 remote_github.pub*”意味着您可以从本地机器连接到您的服务器。
与 GitHub 无关。

如果您想从远程服务器连接到 GitHub，那么您需要该远程服务器帐户拥有您的私钥。

如果你想从本地机器连接到 GitHub，那么 Hostgator 根本不涉及。
