Simple in-network file transfer with barely any overhead.

Last update: May 12, 2022

Overview

fftp

fftp is the "Fast File Transport Protocol". It transfers files quickly between computers on a network with low overhead.

Motivation

FTP uses two ports which makes it inconvenient to reverse proxy. HTTP file servers might be too bulky for certain things, and they aren't as fast as FTP. Both use TCP. This is my duct tape and chicken wire compromise.

Use

The client is ff. The server is ffd.

# Create a file.
mkdir test
echo "hi" > test/test.txt

# Start running a server.
ffd -d MY_LOCAL_IP:8080 test

# List files available.
ff MY_LOCAL_IP:8080 ls

# Download a file.
ff MY_LOCAL_IP:8080 get test.txt

Goals

Minimal communication overhead
Fast
Maintainable

A simple cross-platform remote file management tool to upload and download files over HTTP/S

Releases(v0.2.0)

v0.2.0(Nov 4, 2021)
This release introduces the Fast File Transfer Protocol in a slightly more mature stage. Nothing is final.

There's some new stuff:

You can now list subdirectories

Buffer size is no longer an option

Packet sizes are more consistent

Packet endianness is now enforced

v0.1.0(Sep 26, 2021)
This release introduces the Fast File Transfer Protocol in its earliest stage. Nothing is final.

Right now, the server supports listing of a single directory and chunked downloads. The client supports downloads of multiple files and uPNP with compatible gateways. The addition of uPNP bloats binary size, but may prove useful should authentication and/or encryption be added atop the transport layer.

For now, this is the working setup:

# Create a file. mkdir test echo "hi" > test/test.txt # Start running a server. ffd -d localhost:8080 test # List files available. ff localhost:8080 ls # Download a file. ff localhost:8080 get test.txt

Replay packets from pcap -file to network interface

pktreplay can be used to read packets from pcap file or interface and write them into interface. By default packets are written with the same rate they have been saved into the pcap file, or, when reading from interface, as fast as they are received.
