Crate tftpd

Multithreaded TFTP daemon implemented in pure Rust.

This server implements RFC 1350, The TFTP Protocol (Revision 2). It also supports the following RFC 2347 TFTP Option Extensions:

• RFC 2348 Blocksize Option
• RFC 2349 Timeout Interval Option
• RFC 2349 Transfer Size Option
• RFC 7440 Windowsize Option

Security

Since TFTP servers do not offer any type of login or access control mechanisms, this server only allows transfer and receiving inside a chosen folder, and disallows external file access.

Structs

Config

Configuration struct used for parsing TFTP options from user input.

Convert

Allows conversions between byte arrays and other types.

Server

Server struct is used for handling incoming TFTP requests.

ServerSocket

ServerSocket struct is used as an abstraction layer for a server Socket. This struct is used for abstraction of single socket communication.

TransferOption

TransferOption struct represents the TFTP transfer options.

Window

Window struct is used to store chunks of data from a file. It is used to help store the data that is being sent or received for the RFC 7440 Windowsize option.

Worker

Worker struct is used for multithreaded file sending and receiving. It creates a new socket using the Server’s IP and a random port requested from the OS to communicate with the requesting client.

Enums

ErrorCode

ErrorCode enum represents the error codes used in the TFTP definition.

Opcode

Opcode enum represents the opcodes used in the TFTP definition.

OptionType

OptionType enum represents the TFTP option types

Packet

Packet enum represents the valid TFTP packet types.

Traits

Socket

Socket trait is used to allow building custom sockets to be used for TFTP communication.
