Join them; it only takes a minute: Sign up The remote server returned an error: 227 Entering Passive Mode (500 oops vs_utility_recv_peek: no data) up vote 4 down vote favorite 1 I am having a problem connecting a Windows service to an FTP site. I 227 entering passive mode ftp connect connection timed out 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 pro

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 client connects from a random unprivileged port (N > 1023) to the FTP server's http://geekswithblogs.net/hmloo/archive/2012/10/16/the-remote-server-returned-an-error-227-entering-passive-mode.aspx 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!

Here ftp is an object of FtpWebRequest . set the property UsePassive as "False" (eg: ftp.UsePassive = False ) Set UsePassive property as False before before getting the response. My code is as below: Dim ftp As Net.FtpWebRequest = GetRequest(GetDirectory(directory)) 'Set request to do simple list ftp.Method = Net.WebRequestMethods.Ftp.ListDirectory ftp.UsePassive = False 'Geting response. Dim str As String = GetStringResponse(ftp) Now it works fine. terca-feira, 20 de maio de 2008 09:51 Todas as Respostas 0 Entrar para Votar "227 Entering Passive Mode (...)" is a valid response to an FTP PASV command. I'm not sure why we would be throwing this as an exception. Can you get a debug trace of this happening? I would love to take a look. Instructions are here. -dave quarta-feira, 27 de fevereiro de 200returned an error: 227 Entering Passive Mode-The requested FTP command is not supported when using HTTP proxy. by BillKrat 16. November 2013 02:10 The code below is typical of what you will find for doing an FTP upload using C#. If you don’t have a corporate proxy in the loop I found you don’t even require lines 38-44, it just works. My issue was that I do have a corporate proxy in the loop and these two errors cost me most of the day. There are more dead-ends than answers on the Internet and now that it is over I can actually look back and chuckle at one of the comments made indicating that FtpWebRequest was a joke, don’t use it – they use Code Project’s Ftp Client. I go through the cycles with it by downloading the code and guess what, it uses FtpWebRequest and got me no closer to the answer. Of the two issues I encountered it was the “The requested FTP command is not supported when using HTTP proxy” that ate my lunch (and dinner) because there were more questions than answers on the internet and many of them have you setup the ftp.Proxy (which didn’t work). The reason line 40 was so hard to find and figure out is because if you put a breakpoint on line 36 you will find that ftp.Proxy IS NULL, so you wouldn’t really think to explicitly set it to null – it is obvious now that that property does something behind the scenes when you apply a null value to it.
