我使用生成了 SSH 金鑰網路主機管理員 “管理要在 SFTP 和控制台 SSH 連線上使用的 root 的 SSH 金鑰”。
FileZilla 使用私鑰和密碼輕鬆連接，但當我嘗試在控制台中使用它時，密碼不被允許。

（我不太確定 SSH 金鑰是如何工作的，但我以前使用過它們，就像我現在所做的那樣，而且它有效。）
此連接有什麼錯誤？
添加-vv到命令中，我收到以下訊息：

答案1
如果 FileZilla 能夠使用金鑰和密碼，那麼我認為它可以工作。
我建議您仔細檢查您在控制台中輸入的密碼是否正確。嘗試將 -vv 新增到 ssh 命令中，如下所示：
ssh -vv ...
如果你不這樣做，它會打印出一條調試訊息，簡單地說“給出了錯誤的密碼，請重試......”
