SFTP delivers mangled files if over 40 mb


I've tested multiple files from zip to tar to rar and other compressed files. If the file is over 40 mb, and it's uploaded or downloaded, it's mangled on the target server. This is using scp or sftp. The bytes match exactly, however their's crc and format errors in the compressed files.

This is found to be a problem with VMWare ESX ONLY

Someone on codeproject said if you change the variables dealing with file size into long's instead of ints, you can transfer big files where otherwise would corrupt them. Haven't tried it yet, but I'm going to now.

I tried it, but i'm too unfamiliar with this huge project to make the appropriate changes, could you do it?

I am also experiencing this issue when trying to upload a ~500mb iso file to VMWare ESX

Here are some notes for source code improvements to make this project more manageable:
  1. remove java\String.cs and replace it with System.String
  2. remove java\System.cs and replace it with Array.Copy, Console.WriteLine, and Console.Error.WriteLine where applicable
  3. remove java\Exception.cs and replace it with System.Exception
  4. remove old code (Channel.old.cs) and commented code
  5. improve JStream, PipedInputStream, PassiveInputStream, InputStreamGet, InputStream, FileInputStream, OutputStream, etc. by reusing already existing classes like BinaryReader, BinaryWriter, FileStream, StreamReader, StreamWriter, NetworkStream, etc.
  6. fix compile time warnings
  7. better exception handling (verbosely display\output exceptions)

  1. Find and remove casts like "(int)" and "(long)"
