SSH - 服務器上的權限被拒絕（公鑰）

Question

我正在嘗試在 Hostgator 上的共享主機上使用 git，但在與 Github 建立連接時遇到問題。 我已經在網上嘗試了大量答案，但到目前為止沒有任何改變。

這些是我為實現這一目標而遵循的步驟（我使用了這個 github 指南）：

在我的機器上，

1.我用ssh-keygen -t ed25519 -C "myemail@address.com"了一個新密鑰

2.我保存到文件~/.ssh/remote_github.pub ，文件沒有密碼

3.然后我運行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復制了pbcopy < ~/.ssh/remote_github.pub保存到我的github賬戶

6.然后我運行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:

輸入密碼后：

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.

檢查服務器上的authorized_keys文件，我看到存儲在我的機器中的完全相同的公鑰remote_github.pub *

7.但此時，如果我嘗試運行ssh -T -v git@github.com

這就是我得到的：

debug1: No more authentication methods to try.
Permission denied (publickey).

我還確保使用chmod 700 ~/.ssh和chmod 600 ~/.ssh/authorized_keys更改服務器上的權限，但答案始終是Permission denied (publickey).

我究竟做錯了什么？ 還是失蹤了？

謝謝你。

* authorized_keys文件還包含另一個ssh-rsa公鑰。

Answer 1

首先，如果你的私鑰沒有密碼，你就不需要任何與 ssh-agent 相關的東西。

其次，“他在服務器上的authorized_keys 文件我看到存儲在我的機器中的完全相同的公鑰remote_github.pub*”意味着您可以從本地機器連接到您的服務器。
它與 GitHub 無關。

如果您想從遠程服務器連接到 GitHub，那么您需要該遠程服務器帳戶擁有您的私鑰。

如果你想從你的本地機器連接到 GitHub，那么 Hostgator 根本不涉及。
