为什么 ssh 不使用配置文件中设置的身份？

Question

我正在尝试配置某些 git 存储库以使用特定的公钥/私钥进行身份验证。

这是在 ~/.ssh/config 里面

Host Repo
HostName bitbucket.org
User git
IdentityFile ~/.ssh/ynd
LogLevel DEBUG

这是尝试推送到仓库时的日志

Please make sure you have the correct access rights
and the repository exists.

我可以看到正在查找身份，但当服务器请求公钥身份验证时，它没有使用它来进行身份验证。

我究竟做错了什么？为什么 ssh 不使用配置文件中的 IdentityFile？

Answer 1

看起来，您的会话无法访问指定的密钥，并且它会回退到默认密钥。并且它能够访问 bitbucket ，但是，您无法使用此密钥访问存储库，因此请使用该默认密钥 /Users/evgenipetrov/.ssh/id_rsa 查看存储库权限

还要检查哪些 ssh-key 已加载到 ssh-agent 中，并使用 ssh-add 加载缺少的密钥

Answer 2

LogLevel 调试有帮助。我的里面有这个.ssh/config

Host github.com
 HostName github.com
 UseKeychain yes
 AddKeysToAgent yes 
 User git
 IdentityFile ~/.ssh/id_ed25519

Host github.com-personal
 UseKeychain yes
 AddKeysToAgent yes
 HostName github.com
 User git
 IdentityFile ~/.ssh/id_ed25519_personal

但没有运行ssh-add -K ~/.ssh/id_ed25519_personal将其添加到钥匙串中以防止它回落到其他文件。
