我正在使用 WinScp 访问远程 FTP 服务器。我无法在笔记本电脑上连接，并显示以下消息Can't open data connection。然而，当我的同事在她的计算机上连接时，她可以连接到远程 FTP 站点
我列出了解决方案，我尝试过
- 设置为被动模式：无效
- 设置为活动模式：无效
- 使用另一个 ftp 客户端（这里是 Filezilla）：不起作用
- 在远程防火墙上为服务器开放了端口范围（包括
39000）41000：不起作用 - 根据共享驱动器设置一个 bat 文件，并通过 ftp 访问我想要的服务器：不起作用

不确定该怎么想。
我已经为此奋斗了两天了，因此非常欢迎任何提示或建议。
答案1
由于您使用的是 winscp 而不是scp，我假设您使用的是 Windows。安装“Git Bash”是获取 bash 和 git 的简单方法，但它还包括一些其他方便的实用程序，包括 ssh 和 scp。我会尝试它们来帮助缩小您的问题范围。抱歉，我想不出更直接的解决方案或诊断测试。
答案2
这是一个不太可能的尝试，但我们还是决定尝试一下。
- 您的同事的计算机的 IP 地址是多少？
- 她的 IP 范围和你的 IP 范围不同吗？
- 远程计算机上是否有防火墙规则允许您的同事连接，但不允许您的计算机连接？
可能的解决方案：
- 尝试一下同事计算机的 IP 地址。
- 尝试与同事的计算机处于同一 IP 范围内的 IP。
- 要求服务器团队/客户将您计算机的 IP 纳入他们的防火墙规则。
额外的解决方案：
我个人曾经遇到过这样的情况：如果使用的 Windows 帐户是简单的用户帐户，Windows 7 家庭版就无法连接到 FTP 服务器。使用 Windows 7 家庭版上的管理员帐户登录解决了这个问题。即使您可能使用的是专业版，这也可能是您的客户端的解决方案：使用特权/管理员帐户登录并尝试再次连接到 FTP 服务器。（以管理员身份启动 WinSCP 可能会有效）。
