我在透過 mobaxterm 連接到 AWS 中的 Linux 實例時遇到一些問題。嘗試透過 SSH 連線到伺服器時出現以下錯誤；

有任何想法嗎？我嘗試過使用檔案權限（我從我的Mac知道密鑰必須被很好地鎖定），但任何更改似乎都不會影響我收到的錯誤。
答案1
看來您的問題出在檔案權限上，您可以透過 mobaxterm 檢查密鑰是否位於您嘗試執行 ssh 命令的資料夾中？
ls -lh從 Mobaxterm 控制台執行並檢查檔案XYZ.pem是否存在，以及執行 mobaxterm 的使用者的擁有者和群組，以及權限 600 (-rw--------)。
我不是 MAC 專家，不過，我很確定它預設有一個 ssh 客戶端，看看這個關聯
答案2
卸載 Mobaxterm。在不在「程式」下的某個位置重新安裝，因為您不再具有對那裡的寫入存取權。
