我ssh-ing從server1到server2。我生成了id_rsa & id_rsa.pub文件。如果我ssh到麥克@ server2它工作正常，但ssh到約翰@ server2不工作沒有密碼。兩個麥克& john主目錄包含「.ssh」，它是chmod 700，該文件夾包含「authorized_keys」，其中只包含之前生成的id_rsa.pub文件（並且是chmod 600）的內容。兩者的內容都是一樣的。麻煩ssh和authorized_keys

任何人都有的，爲什麼它會與一個用戶工作思路，而不是另一個（兩者是在同一臺服務器上）？
如果公鑰/私鑰出現問題，是否會影響與其他ID的連接？ – askmike1 2012-04-07 04:57:31
注意「公鑰是用於與私鑰不同的密鑰」。從文件大小來看，我猜你在第一個賬戶的authorized_keys中有另一個密鑰。也許那個其他的密鑰實際上是你在ssh時使用的密鑰？ – 2012-04-07 07:12:33
我從mike的authorized_keys中刪除了另一個密鑰，它仍然與該用戶一起工作。 – askmike1 2012-04-07 11:34:36
