如何設置 SCP 從 localhost 到遠端 Ubuntu 伺服器 - 第 2 部分

我正在嘗試配置一個 ubuntu vps。我已經使用本地機器上的 rsa 公鑰和私鑰設置了 ssh 安全登錄。

除了禁用 root 登錄外，我還設置了 iptables 並配置為允許 ssh 隧道使用埠 80 和 22（僅來自我的 IP 地址的埠 22）。

我可以使用 ssh 正常連接，但是當我嘗試從本地電腦使用 scp 時

sudo scp /var/www/filetocopy user@remoteaddress:/var/www/filetocopy

我收到這個錯誤

Permission denied (publickey).

我添加了 -v 來顯示輸出

再次感謝到目前為止的幫助

authorized_keys如果我從遠端主機中刪除 ，我可以獲得與您相同的結果的唯一方法。檢查公鑰是否user@remoteaddress:~/.ssh/authorized_keys與本地電腦上使用者的身份文件匹配。
