tftpd

TFTP Server

A simple TFTP server implementation that can handle both read and write requests. Mainly added for integrations tests for tftp (client).

Overview

This TFTP server uses the same underlying package as the u-root TFTP client (pack.ag/tftp). It implements the basic TFTP protocol as defined in RFC 1350 with support for:

• READ requests (GET)
• WRITE requests (PUT)
• Security against directory traversal attacks
• Both binary and netascii transfer modes

Usage

tftpd [-port PORT] [-root DIRECTORY] [-v]

Options

• -port: Port to listen on (default 69)
• -root: Root directory to serve files from (default current directory)
• -v: Enable verbose logging

Example

Start a TFTP server that listens on port 6969 and serves files from /tmp/tftp:

tftpd -port 6969 -root /tmp/tftp

Testing with the u-root TFTP Client

To test file transfer between the client and server:

1. Start the server in one terminal:

   tftpd -root /tmp/tftp
   

2. In another terminal, use the u-root TFTP client to transfer files:

   # Get a file
   tftp localhost -c get test.txt
   
   # Put a file
   tftp localhost -c put test.txt
