我在使用OpenSSH for Windows使用公鑰認證時遇到了問題。我已經生成密鑰對並將密鑰正確傳輸到遠程服務器，但是當我在Windows上使用ssh時，它會一直提示輸入密碼。我將相同的私鑰傳給了我的mac，並且出現了一個錯誤，即權限過於開放（644），並且會被忽略，除非設置爲600.「chmod 600 id_rsa」和繁榮，它工作。我似乎無法找出通過腳本在Windows上更改此方法的方法，但我無法使用gui進行此操作。OpenSSH公鑰與Cygwin不兼容
必須有一個簡單的方法來做到這一點嗎？有沒有一個內置的windows命令？即時通訊目前使用的是XP，但需要這也對Vista的工作，7
EDIT3：我報廢了FAT32支持和下載一個完整的cygwin的安裝只是爲了幫助診斷問題，並使用搭配chmod 600設置權限（其幸運地設置窗戶）。仍然是一個失敗。所以我猜這個問題不是權限，而是導致密鑰失敗的其他問題。
EDIT2： 我設法找到一個cacls命令可能會做什麼，我需要，但它只會在NTFS文件系統的工作顯然，我需要支持FAT32。
EDIT1：當我在3倍詳細模式運行OpenSSH中，我們這是我得到：

所以它似乎拿到鑰匙，發送測試數據包，然後跳到右邊進入下一輪的認證。
