我試圖通過ssh連接到我的嵌入式板。但在試圖通過ssh -v -l root [email protected]連接時，我得到了一系列的調試評論：從ssh登錄中刪除publickey
[email protected]:~$ sudo ssh -v -l root [email protected]

連接正在通過端口22建立的，這樣是沒有問題的。所以，顯然公鑰/私鑰身份驗證存在問題。因此，如何確保通過我的機器和主板的私鑰/公鑰都保持同步？或者更好的是，我該如何解決這個問題或完全刪除任何密鑰？
UPDATE
我試着通過ssh -o PubkeyAuthentication=no [email protected]沒有指定公共密鑰身份驗證連接到主板，但現在它問我輸入密碼。我檢查了site但我輸入的密碼不正確。我如何刪除密碼請求？
它正在嘗試使用您的公鑰進行身份驗證，針對root的私鑰進行身份驗證並且失敗。要解決這個問題，你的〜/ .ssh.id_rsa.pub文件的內容需要附加到你試圖連接的服務器上的/root/.ssh/authorized_keys。這樣做需要你已經有一些方法來以root身份進行連接，或者有人可以爲你做。 –
