I'm receiving the following error when trying to connect to a remote FTP site:
System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
at System.Net.Sockets.Socket.Connect(EndPoint remoteEP)
at WebCamService.FtpClient.createDataSocket()
--- End of inner exception stack trace ---
at WebCamService.FtpClient.createDataSocket()
at WebCamService.FtpClient.Upload(String fileName, Boolean resume)
at WebCamService.FtpClient.Upload(String fileName)
at Xhibitnet.AssetProcessing.PackageAndDeploy.UploadArchive(String archiveFilePath, String teamName)
I suspect the problem is somehow related to passing through a firewall, but I'm not sure how to solve it.
My FTP Code works perfectly when transferring to a local FTP Server.
I can FTP to the remote server using the Windows command line FTP Client.
The machine running the edtftp component is Windows XP Pro with Service Pack 2 (with the firewall disabled).
The remote server is a Windows 2003 server.
Here is the code that fails:
_FileTransferClient.ConnectMode = FTPConnectMode.PASV;
_FileTransferClient.RemoteHost = remoteHost;
_FileTransferClient.Timeout = 5000;
_FileTransferClient.Connect();
_FileTransferClient.Login(remoteUsername, remotePassword);
string[] DirectoryList = _FileTransferClient.Dir(); // Exception occurs here
Finally, here are the logs from the FTP Component:

Thanks for any suggestions on solving this problem,
Shawn.
