I inherited a Windows service from another developer. The service

connects to a 3rd party server, downloads a csv file and then processes it. For some reason, the service stopped working (well over a year ago, before I was given the project). So I went back to basics, created a console app and tried the connection/ file download function only in that app. I have tried many different methods to connect to the FTP, but all of them return the same error to my application: The remote server returned an error: 227 Entering Passive Mode () This is one of the many methods I've tried: FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftpaddress/filename.csv"); request.Method = WebRequestMethods.Ftp.DownloadFile; request.Credentials = new NetworkCredential("username", "password"); request.UsePassive = true; FtpWebResponse response = (FtpWebResponse)request.GetResponse(); Stream responseStream = response.GetResponseStream(); StreamReader reader = new StreamReader(responseStream); Console.WriteLine(reader.ReadToEnd()); Console.WriteLine("Download Complete, status {0}", response.StatusDescription); reader.Close(); response.Close(); But it falls down on this part: FtpWebResponse response = (FtpWebResponse)request.GetResponse(); I read in several forums that setting the UsePassive property to False fixes these errors, but all that happened to me was that I got a synta

Synopsis This http://www.serv-u.com/respcode.asp?resp=227 is the response given by the server to the PASV command. It indicates that the server is ready for the client to connect to it for the purpose of establishing a data connection. The format of this response is important because the client software must be capable of parsing out the connection information it contains. The values of h1-h4 are the IP address the server is listening on. The values of p1-p2 are used to calculate the port the server is listening on using the following formula: PASV port = (p1 * 256) + p2.

FTP may run in active or passive mode, which determines how the data connection is established. Active mode: command connection: client >1024 -> server 21 data connection: client >1024 <- server 20 passive mode: command connection: client > 1024 -> server 21 data connection: client > 1024 <- server > 1024 In active mode, the ftp error code client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the client will use PORT command to tell the server:"hi, I opened port XXXX, please connect to me." and then server will use port 20 to initiate the data connection to that client port number. In passive mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the sever will tell the client:"hi, I opened port XXXX , please connect to me." and then client will initiate the data connection to that sever port number. In a nutshell, active mode is used to have the server connect to the client, and passive mode is used to have the client connect to the server. So if your FTP server is configured to work in active mode only or the firewalls between your client and the server are blocking the data port range, then you will get error message, to fix this issue, just set System.Net.FtpWebRequest property UsePassive = false. Hope this helps! Thanks for reading!
