嘗試使用 scp 命令（或 sftp 或 ssh）將簡單的 txt 檔案（很快就會成為 csv 檔案）從 Windows Server 2019 傳送到遠端伺服器。遠端伺服器員工給了我們一個用於登入的使用者名稱和密碼。 WinSCP 工作正常。我們的安全團隊希望我們不要使用 WinSCP，而是使用 ssh 實現自動化（目前他們正在嘗試使用 scp 找到一種方法）。
初始命令（連接埠已編輯）：
scp -v -P ***** Test.txt username@remoteserveraddress:/
此處輸出：
C:\Users\username>scp -v -P ***** Test.txt username@remoteserveraddress:/
Executing: program ssh.exe host remoteserveraddress, user username, command scp -v -t /

根據這一行，您顯然正在連接到名為的伺服器產品Solarwinds 的“Serv-U”。
根據這一頁，Serv-U不支援SCP協定。您將需要使用其之一來存取伺服器支援的協議。對於基於 SSH 的檔案傳輸，它顯然支援 SFTP。
