TFTP Server

Features

Managed TFTP server implementation with the following features:

• Open source
• works both in IPv4 and IPv6 mode.
• correct retry behavior
• supports the following TFTP options: block size, transfer size, and timeout.
• it's possible to run in single port mode: this ensures that only port 69 will be used for TFTP transfers, simplifying firewall and router configuration.
• supports many concurrent transfers.
• as of 1.2 beta : supports windowed mode, enabling high speed downloads.
• Runs as windows service.
• Supports multiple TFTP servers on different endpoints, each serving its own root directory.
• Advanced MSI based installer.
• Logs to the windows event log.
• permissive MIT license so it can be used in commercial projects.

Tested clients

The server has been successfully tested with the following clients:

• my multiplatform graphical desktop TFTP client: Avalonia-TFTPClient
• my TFTP client library TFTPClient
• windows 7 TFTP
• Win32: TFTPD32 by Philippe Jounin
• ubuntu/linux Advanced TFTP client, ATFTP
• ubuntu/linux TFTP
• ubuntu/linux TFTP-hpa
• B&R PLC bootloader

Tested platforms (so far)

• 64 bit Windows 11
• 64 bit Windows 10
• 64 bit Windows 7
• 32 bit Windows XP
• 64 bit Windows Vista
• Linux! The main TFTP library compiles and runs without modifications in Mono . All I had to do was create a small console app that instantiates the TFTPServer class.

tftpserver's Issues

How to set the Blocksize when create TFTP object?

The WindowSize is offered as parameter:
public int TFTPWindowSize { get; set; } = 8;
tftp_server.WindowSize = (ushort)TFTPWindowSize; // = Default: 1

But I see no possbility to set the DefaultBlockSize when create the TFTP object.

May can you help me and add something similar to the code?
public int TFTPBlockSize { get; set; } = 8192;
tftp_server.DefaultBlockSize = TFTPBlockSize ; // = Default: 512

Consider adding optional UTF-8 encoding support for filenames

Currently TFTP does not support non-ASCII filenames (e.g. Chinese). This could be fixed by (optionally) encoding and decoding the filename fields as UTF-8.

Invalid configuration file.

A static configuration file is set in program.cs,

Could you upload a template/example for the xml formatting to refer to. I have attempted manually recreating the path "C:\programdata\JPMikkers\TFTP Server\Configuration.xml" but experience exceptions.

Many thanks.
