MAC Version : 10.10.5 uname -a Darwin xxxxx-xxxx 14.5.0 Darwin Kernel Version 14.5.0: Tue Sep 1 21:23:09 PDT 2015; root:xnu-2782.50.1~1/RELEASE_X86_64 x86_64問題：
無法在使用者模式下使用 SSH 私鑰連接到伺服器。但是，具有相同 SSH 密鑰（與使用者位於相同位置）的相同命令適用於 root 身份驗證。

我已將根級 ssh_config 更改為指向使用者級帳戶的私鑰，而不是預設的 rsa 密鑰。
我嘗試過
的：嘗試了使用者級別文件夾
.ssh和internal的不同權限，但不影響。灣。嘗試過
ssh-add，但看到看起來不錯的輸出。C。在使用者級別和根級別檢查 known_hosts 並且看起來相同。
不知道是什麼導致了這個問題 - 因為在根級別我能夠驗證密鑰，而在使用者級別則不能這樣做。
歡迎任何幫助。
由於您沒有在 ssh 命令行上指定特定的使用者名：
root當您使用時，您使用遠端系統上的使用者登錄，而當您不使用時，您使用的是sudo普通 OSX 使用者userxyz（或kimanjun其他使用者）登錄。
ssh root@198.18.144.158當您省略sudoor時嘗試ssh -l root 198.18.144.158。如果您不想以 root 身份登錄，請改用正確的遠端登錄名並設置正確的 SSH 密鑰。
