ssh配置不起作用。 權限被拒絕（公鑰）

Question

我的ssh配置有問題。 我有多個密鑰對和多個主機，所以我想設置ssh配置，以便我可以輕松地在它們之間切換。

我的ssh配置如下所示：

Host blog
    User Myusername
    HostName github.com
    IdentityFile ~/.ssh/macbook_id_rsa

Host blog2
    User Myusername2
    HostName github.com
    IdentityFile ~/.ssh/macbook_2_id_rsa

現在，如果我只是使用ssh-add添加我的私鑰並輸入密碼，我就能連接到github或其他主機。 但當我嘗試切換不同的密鑰對時

ssh -vT blog

我收到如下錯誤信息：

任何人都可以指出我的ssh配置是否有問題，或者我在這里缺少什么。 謝謝

你應該使用git作為用戶名。 在這種情況下

User git
