来自IIS7上的ASP.NET应用程序的FTP失败

I have a problem that only occur when I run my application from the IIS.

我有一个问题,只有当我从IIS运行我的应用程序时才会出现。

I am trying to FTP from my ASP.NET application to an external site.

我正在尝试从我的ASP.NET应用程序FTP到外部站点。

I can FTP from the server in general but not from my application. My request times out.

我可以从服务器FTP一般但不能从我的应用程序。我的请求超时了。

The owner of my Website is now set to the IIS_IUSRS user with Full control.

我的网站所有者现在设置为具有完全控制权的IIS_IUSRS用户。

Do anyone have ANY idea what might keeps me from succeeding?

有没有人知道什么可能阻止我成功?

#1

A quick fix may be setting the anonymous user that IIS uses to your user account instead of the IUSR account (in IIS). It does seem to be a permission problem.

快速修复可能是将IIS使用的匿名用户设置为您的用户帐户而不是IUSR帐户(在IIS中)。它似乎确实是一个许可问题。

Second bet would be to use a tool like Wiresharck/Etherreal and check if any connection to the FTP site is made, and debug from there.

第二个赌注是使用像Wiresharck / Etherreal这样的工具,并检查是否有任何与FTP站点的连接,并从那里进行调试。

I Found the Solution

我找到了解决方案

Windows Firewall and non-secure FTP traffic

Windows防火墙和非安全FTP流量

Windows firewall can be configured from command line using netsh command. 2 simple steps are required to setup Windows Firewall to allow non-secure FTP traffic

可以使用netsh命令从命令行配置Windows防火墙。设置Windows防火墙以允许非安全FTP流量需要2个简单步骤

1) Open port 21 on the firewall

1)在防火墙上打开端口21

netsh advfirewall firewall add rule name="FTP (no SSL)" action=allow protocol=TCP dir=in localport=21

netsh advfirewall防火墙添加规则名称=“FTP(无SSL)”action = allow protocol = TCP dir = in localport = 21

2) Activate firewall application filter for FTP (aka Stateful FTP) that will dynamically open ports for data connections

2)激活FTP(又名状态FTP)的防火墙应用程序过滤器,它将动态打开数据连接端口

netsh advfirewall set global StatefulFtp enable

netsh advfirewall设置全局StatefulFtp启用

I don't really know what that just did but it did the trick

我真的不知道刚刚做了什么,但它确实做到了

Same problem solve UsePassive. Maybe you can add allow port 20,21 for FTP on firewall (For me not necessery).

同样的问题解决了UsePassive。也许你可以在防火墙上为FTP添加允许端口20,21(对我来说不是必需的)。

FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(@"ftp://ftp.example.com/"));
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential("user", "password");
reqFTP.Proxy = null;
reqFTP.KeepAlive = false;
reqFTP.UsePassive = true;
