Winscp - 嘗試登錄到遠端網站並且無法打開數據連接

  • November 1, 2016

我正在使用 WinScp 訪問遠端 ftp 伺服器。我無法在筆記型電腦上連接，出現以下消息Can't open data connection。然而，當我的同事在她的機器上連接時，她可以連接到遠端 ftp 站點

我列出了解決方案，我試過了

  • 設置為被動模式：無效
  • 設置為活動模式：無效
  • 使用另一個 ftp 客戶端（此處為 Filezilla）：沒用
  • 為伺服器打開遠端防火牆上的埠範圍（包含39000到41000）：沒有工作
  • 基於共享驅動器設置一個 bat 文件，並通過 ftp 訪問我想要 ftp 的伺服器：沒有工作

不知道該怎麼想。

任何提示或提示都非常受歡迎，因為我已經為此苦苦掙扎了兩天。

由於您使用的是 winscp 而不是scp，因此我假設您是 Windows。安裝“Git Bash”是獲取 bash 和 git 的簡單方法，但它還包括一些其他方便的實用程序，包括 ssh 和 scp。我會嘗試幫助他們縮小您的問題範圍。抱歉，我想不出更直接的解決方案或診斷測試。

這是一個很長的鏡頭，但在這裡。

  1. 你同事電腦的IP地址是多少？
  2. 她的 IP 範圍是否與您不同？
  3. 遠端電腦上是否有防火牆規則允許您的同事連接，但不允許您的電腦連接？

可能的解決方案：

  1. 試試你同事電腦的 IP 地址。
  2. 嘗試使用與同事電腦相同 IP 範圍的 IP。
  3. 要求伺服器團隊/客戶將您電腦的 IP 包含在他們的防火牆規則中。

獎勵解決方案：

如果使用的 Windows 帳戶是一個簡單的使用者帳戶，我個人遇到過 Windows 7 家庭版無法連接到 FTP 伺服器的情況。在 Windows 7 Home Edition 上使用管理帳戶登錄解決了該問題。這可能是您的客戶的解決方案，即使您可能使用的是專業版：使用特權/管理帳戶登錄並嘗試再次連接到 FTP 伺服器。（可以通過以管理員身份啟動 WinSCP 來工作）。
