亞馬遜EC2 RSA密鑰已停止驗證 - 許可被拒絕（公鑰）

驗證我們的Ubuntu EC2實例之前一直運行良好。突然之間，關鍵是被拒絕。當我們使用密鑰對創建一個新實例時，我們能夠完美地連接到實例，所以它似乎是現有實例的問題。 22號港口已開放。亞馬遜EC2 RSA密鑰已停止驗證 - 許可被拒絕（公鑰）

關於從配置的角度來看待什麼的建議，以便我們解決這個問題？關於我們如何進入箱子的任何想法？

這裏是SSH調試輸出。有什麼明顯的錯誤嗎？

非常感謝！

如果機器沒有其他用戶，那麼如何才能我們解決了這個問題？ – 2011-01-13 14:56:49

我有同樣的問題。您能否解釋更多細節並指定如何解決問題非常感謝 – 2011-01-13 14:57:02

這是authorized_keys的一個很好的參考 - http://www.eng.cam.ac.uk/help/jpmg/ssh/authorized_keys_howto .html - 如果我記得，我們基本上找到了一個可以訪問並且能夠修復authorized_keys文件的用戶。 – shedd 2011-01-13 14:57:02

我們知道這裏出了什麼問題。盒子上的用戶覆蓋了主〜/ .ssh/authorized_keys - 他能夠登錄並檢查該文件並將主.pem密鑰返回。
