I am having issues with ftpClient. The connect method works but then FileExists throws a time out exception. This happens only on Wifi

New Post: Separate trace listener per instance?
It's not possible in its current form. My recommendation would writing a custom TraceListener that directed data based on the Thread ID or parent Process ID.

New Post: Changing access right to file
How to change rights to file on the server. I use the Execute but I get error: CHMOD not understood
if (!(reply = conn.Execute("chmod 666 file.txt")).Success)
{
throw new FtpCommandException(reply);
}↧
New Post: Changing access right to file
There's already a set of methods for doing this. You're missing the SITE command (chmod is a native FTP command). That said, it doesn't mean the server will support chmod but assuming it does the provided methods in FTP client should work fine. If you still wanted to do it with the Execute() method your code would need to look something like this:
if (!(reply = conn.Execute("SITE chmod 666 file.txt")).Success)↧
New Post: Windows 8.1 hangs randomly
We are auto uploading mixed items from about 20 machines. I have one windows 8.1 machine that after a random period of time hangs. It apparently opens the stream, then hangs, as there is a 0 length file left on the server. Over the course of 15 minutes, there is probably 350K data uploaded.
This is compiled using dotnet 2.0, which I don't feel is the issue. This issue happens with the latest code, as well as code from 2012, not sure which version.
This is a partial trace from when this hangs at 150 etc. I really don't know, after the 150 Accepted data connection, whether those Disposing lines are from the following external calls from elsewhere, or what. Pond_2_CalHistory1.png is a zero length file on the server.

New Post: Text files get truncated
I am trying to write some code that copies some .txt files from an FTP server to a local directory in my asp.net web application. The code seems to run fine, but the resulting files are only partially complete and half of the file is filled with whitespace. This is the code I am using:
Dim ftp As New FtpClient
ftp.Host = ConfigurationManager.AppSettings("FTPserver")
ftp.Credentials = New NetworkCredential(ConfigurationManager.AppSettings("FTPuser"), ConfigurationManager.AppSettings("FTPpassword"))
Dim fileCount As Integer = 0
For Each item In ftp.GetListing("/IPRT")
If item.Type = FtpFileSystemObjectType.Directory Then
For Each innerItem In ftp.GetListing("/IPRT/" & item.Name)
If innerItem.Type = FtpFileSystemObjectType.File Then
SaveStreamToFile(path & innerItem.Name, ftp.OpenRead(innerItem.FullName))
ftp.Rename("/IPRT/" & item.Name & "/" & innerItem.Name, "/IPRT/" & item.Name & "/Archive/" & innerItem.Name)
fileCount = fileCount + 1
End If
Next
End If
Next
Return fileCount
End IfPublic Shared Sub SaveStreamToFile(ByVal path As String, ByVal stream As Stream)
If stream.Length <> 0 Then
Dim bytesInStream(stream.Length - 1) As Byte
stream.Read(bytesInStream, 0, bytesInStream.Length)
File.WriteAllBytes(path, bytesInStream)
End If
End Sub↧

New Post: How to get FTP server response on upload
Hi,
I recently started using FtpClient library. So far so good. The only shortcoming I face now is not able to retrieve the server response after a successful file upload.
I am connecting to a Mainframe FTP server. Here is the response captured

If you can send me a transaction log from System.Net.FtpClient (see Examples\Debug.cs) I'll look into this further.

Hi jptrosclair,
Thanks for quick reply. Here is the log. I just replaced the host name and username. What I am trying to do is to download a file, edit it and then put it back to Mainframe. I just want to make sure I capture the reply from server after uploading the file. Mainly these two lines

Changed accessor for FtpDataStream so you can cast your Stream objects to it if necessary.
↧
New Post: How to get FTP server response on upload
Alright, the latest commit has a few things you'll be interested in. To use them cast the Stream object to a FtpDataStream. That should give you access to the public property CommandStatus which is a FtpReply object saved from the command used to open the data stream (STOR in the example above, so the 125 message after). This is actually an old property used internally in System.Net.FtpClient so don't change it unless you understand the consequences. The other change is the Close() method of the stream should now return the response that's read when the stream is closed, so the 250 messages you want. A better example:
static void StreamResponses() {
using (FtpClient cl = new FtpClient()) {
cl.Credentials = new NetworkCredential(m_user, m_pass);
cl.Host = m_host;
cl.EncryptionMode = FtpEncryptionMode.None;
using (FtpDataStream s = (FtpDataStream)cl.OpenWrite("test.txt")) {
FtpReply r = s.CommandStatus;
Console.WriteLine();
Console.WriteLine("Response to STOR:");
Console.WriteLine("Code: {0}", r.Code);
Console.WriteLine("Message: {0}", r.Message);
Console.WriteLine("Informational: {0}", r.InfoMessages);
r = s.Close();
Console.WriteLine();
Console.WriteLine("Response after close:");
Console.WriteLine("Code: {0}", r.Code);
Console.WriteLine("Message: {0}", r.Message);
Console.WriteLine("Informational: {0}", r.InfoMessages);
}
}

If you need more than that you'll want to hook in with a trace listener to monitor the server activity; basically parse the responses yourself.

Hi jptrosclair,
Thanks for quick response. I would try both options and see which works best for me.
Also thanks for the wonderful library for free. You rock... :)
