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.
