#12846 fixed Wrong data returned (possibly after an ABOR command) nickj

It appears that after an ABOR command, incorrect data may be returned. In my specific case, I was trying to download file chunks, and providing offsets to FileZilla. The first chunk returned (offset 0) is correct. However, subsequent downloads return incorrect data.

This is the C# pseudocode used:

[code] public async Task TestFileZilla() {

var ftpClient = GetUiFtpClient(); await ftpClient.ConnectAsyc().ConfigureAwait(false);

var ftpBuffer = new byte[1024 * 1024]; var fileBuffer = new byte[1024 * 1024];

var random = new Random();

these are pointing to the same file var remoteFile = "/test/"; var localFile = "c:

for (var i = 0; i < 10; i++) {

just randomly check the byte stream for a >= 100MB file var offset = random.Next(0, 100 * 1024 * 1024);

underlying rebex call is -> GetDownloadStreamAsync(path, SeekOrigin.Begin, offset); using var ftpStream = await ftpClient.OpenFileAsync(remoteFile, offset).ConfigureAwait(false);

using var fileStream = new FileStream(localFile, FileMode.Open, FileAccess.Read); fileStream.Seek(offset, SeekOrigin.Begin);

var ftpBytesRead = await ftpStream.ReadAsync(ftpBuffer, 0, ftpBuffer.Length).ConfigureAwait(false); var fileBytesRead = await fileStream.ReadAsync(fileBuffer, 0, fileBuffer.Length).ConfigureAwait(false);

for (var j = 0; j < Math.Min(ftpBytesRead, fileBytesRead); j++) {

if (ftpBuffer[j] == fileBuffer[j])


Console.WriteLine($"Byte mismatch on loop {i} at buffer offset {j}. Expecting {fileBuffer[j]}, got {ftpBuffer[j]}."); break;



} code

I asked the Rebex support staff to verify their library is issuing the correct calls, and this is their response:

So this indeed looks like a FileZilla issue, and it occurs even when I use an offset of “1” every time.

To rule out a client-side issue, I captured the FTP traffic using Wireshark and analyzed it. The control connection looks OK, with the client attempting to download the same file twice:

TYPE I 200 Type set to I

PASV 227 Entering Passive Mode (10,0,0,196,230,208) REST 1 350 Restarting at 1 RETR /incoming/ 150 Starting data transfer. ABOR 426 Data connection closed; transfer aborted. 226 ABOR command successful.

PASV 227 Entering Passive Mode (10,0,0,196,230,209) REST 1 350 Restarting at 1 RETR /incoming/ 150 Starting data transfer. ABOR 426 Data connection closed; transfer aborted. 226 ABOR command successful.

However, data that was transmitted over the second data connection is clearly wrong. Apparently, instead of sending file data that starts at offset 1, FileZilla sends data from seemingly semi-random offsets such as 0x40001 or 0xA0001. So interestingly, FileZilla got the lower 16 bits of the offset correctly, but then used wrong value for the next 16 bits.

Out of interest, I added ftpClient.GetList() as the first call in your “for (var i = 0; i < 10; i++)“ loop, and the results were even weirder – on the second iteration, the server actually transmitted some part of data instead of the directory listing. Because I also had “ftpClient.LogWriter = new ConsoleLogWriter(LogLevel.Debug)“ in the code, this actually showed up like this:

So please do open a FileZilla ticket for this – it looks like something very wrong is going on at the server indeed! My guess is that it has something to do with “ABOR” command – apparently, although it does stop the current transfer (before all data has been transmitted), part of the remaining data remains in some buffer and is later sent via data connection belonging to a subsequent command.

#12845 rejected Mime type mapping for HTML file for SFTP upload to an Azure Storage Account doesn't upload the file as text/html cs981khx

I've purchased FileZilla Pro 3.62.0 which claims to have mime type mapping The target is an SFTP location hosted by an Azure Storage Account = StorageV2 (general purpose v2) with SFTP functionality enabled

I can see that mime type for HTML file is already configured in screenshot attached, however after uploading an HTML file to destination, its file type is being set to "application/octet-stream"

As per the mime-type mapping it should have been set to "text/html"
