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 platforms (so far)

• 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.
