Windows 中的 FTP 命令挂起并显示“150 从...的服务器打开文件下载的数据通道”

Question

我在 Windows Server 2012 机器上有一个 FTP 服务器，我正在尝试从中获取 setup.exe。

CMD.EXE 日志：

C:\>ftp 1.2.3.4
Connected to 1.2.3.4.
220-FileZilla Server version 0.9.45 beta

ftp> get setup.exe
200 Port command successful

.. and stays like this

为什么它适用于 FileZilla，但不适用于命令行中的 Windows FTP？

除此之外，我还想要一个执行一次的命令会从该 FTP 下载此文件而无需询问密码。

有什么想法吗？

谢谢。

Answer 1

它在 FileZilla 中工作，因为 FileZilla 默认为被动 FTP 模式，这对防火墙/NAT 更友好。 Windows FTP 命令行客户端 (ftp.exe) 在任何版本的 Windows 上不仅默认为主动模式，甚至不支持被动模式。由于无处不在的防火墙和 NAT，它现在变得非常无用。

阅读我关于active and passive FTP connection modes 的文章，了解为什么必须使用被动模式。

请改用任何其他 Windows FTP 命令行客户端。其他大多数都支持被动模式。

例如WinSCP 默认为被动模式，并且有一个可用于转换Windows FTP script to WinSCP script 的指南。

您可以专门使用批处理文件 (.bat)，例如：

winscp.com /command ^
    "open ftp://my_username:password@1.2.3.4/" ^
    "get setup.exe" ^
    "exit"
