SCP 使用 RSA 密鑰請求密碼

我已經遵循了一些關於設置 RSA 公鑰身份驗證的教程，但我似乎無法讓它工作。我可以在沒有密碼的情況下通過 SSH 連接到遠端機器，但是當我嘗試使用 scp 文件時，即使它接受了密鑰，我仍然會收到輸入密碼的提示…

這是輸出…

提前感謝您的幫助！

您的密鑰未被接受：

debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/nsizemore/.ssh/id_rsa
debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: password

請檢查伺服器日誌而不是客戶端日誌。

您可能正在使用公鑰（而不是私鑰）進行連接。確保 id_rsa 確實包含您的私鑰。
