Version 4.74

Tftpd Version 4.74

Small release, including quality-of-life improvements — > 4 GB file support and smoother configuration handling.

---

🆕 Highlights

• Support for files larger than 4 GB.
• Server Interfaces dropdown is smarter:
  • Loopback interfaces are listed at the end.
  • Reminder: all interfaces are active by default (unless restricted in Settings).
    You don’t need to select an interface for it to work — doing so just copies its IP address to the clipboard, which can be handy when uploading firmware.
    Similarly, selecting a file in the “Show Dir” box copies its name to the clipboard.
• DHCP settings are now correctly saved.
• INI file lookup now searchs settings also in the executable directory.
• Fixed an internal issue where SetIniFile was called twice.

Changelog

Added

• Support for transferring files larger than 4 GB.

Changed

• UI: Loopback interfaces are moved to the bottom of the Server Interfaces list to keep real interfaces first.
• Config discovery: The INI file is now searched across multiple directories, including the program’s own folder.

Fixed

• DHCP settings persistence: DHCP settings are now saved as expected.
• Initialization: Removed a unnecessary duplicate call to SetIniFileName

Version 4.73

Tftpd32 / Tftpd64 v4.73 – Release Notes

New

• Automated test suite (pytest)
  Includes legal RRQ/WRQ calls, malformed/forged packets, and configurable stress tests.

• Improved INI file search logic
  The application now tries several locations, in order:

  1. Environment variable TFTP_INI (explicit file path).
  2. Environment variable TFTPD32_INI_DIR (directory path).
  3. %APPDATA% directory (per-user roaming settings).
  4. %LOCALAPPDATA% directory (per-user local settings).
  5. %PROGRAMDATA% directory (system-wide settings).
  6. Application directory (fallback, same as previous versions).

  This allows non-admin users to change settings in their profile,
  while administrators can still enforce a global configuration in ProgramData.

Refactor Installers (NSIS)

64 and 32 bits installers merged
Ini file copied from %ProgramData% to %APPDATA%

Executables & Metadata

• Single .rc per target handles both 32-bit and 64-bit builds.
• Updated VERSIONINFO:
  • CompanyName matches signing cert:
    “Open Source Developer, Philippe Jounin”
  • Correct OriginalFilename (tftpd32.exe, tftpd64.exe, tftpd32_svc.exe, tftpd64_svc.exe).
  • Added ProductName, FileVersion, ProductVersion, InternalName, Comments.
  • Dual string tables for fr-FR and en-US.
  • FileDescription shows edition and bitness (32-bit / 64-bit).

Security / Trust

• All binaries code-signed with Certum Open Source Developer certificate and timestamped.
• No UPX/packer → reduces false positives.
• Metadata aligned with certificate to improve reputation with AV vendors.
• Process in place to report false positives to vendors when detected.

Fixes / Behavioral

• Start-menu Uninstall shortcut confirmed (previously hidden by Windows menu).

Testing

• Dependency-free TFTP client utility + pytest suite:
  • RRQ/WRQ round-trip (write tests auto-skip if server is read-only).
  • Forged packets: invalid opcode, stray ACK/DATA to port 69 (server may ignore or reply with ERROR).
  • Stress tests: parallel RRQs/WRQs with env-tunable concurrency.
• README with environment variables (TFTP_HOST, TEST_READ_FILE, TEST_WRITE_DIR, …) and quick-start.

---

Upgrade Notes

• If you previously kept tftpd32.ini beside the exe, this still works.
• For per-user customization, place the INI in %APPDATA% or %LOCALAPPDATA%.
• For system-wide configuration, place it in %PROGRAMDATA%.
• Advanced: override with environment variables TFTP_INI or TFTPD32_INI_DIR.
