Direct file transfer over WebRTC

GFile

gfile is a WebRTC based file exchange software.

It allows to share a file directly between two computers, without the need of a third party.

Note

This project is still in its early stage.

How does it work ?

The STUN server is only used to retrieve informations metadata (how to connect the two clients). The data you transfer with gfile does not transit through it.

More informations here

Usage

Sender

gfile send --file filename

• Run the command
• A base64 encoded SDP will appear, send it to the remote client
• Follow the instructions to send the client’s SDP to your process
• The file transfer should start

Receiver

# SDP being the base64 SDP gotten from the other client
echo "$SDP" | gfile receive -o filename

• Pipe the other client’s SDP to gfile
• A base64 encoded SDP will appear, send it to the remote client
• The file transfer should start

Benchmark

gfile is able to benchmark the network speed between 2 clients (1 master and 1 slave) with the bench command. For detailed instructions, see Sender and Receiver instructions.

This feature is still an experiment.

# Run as 'master'
gfile bench -m

# Run as 'slave'
echo "$SDP" |  gfile bench

Web Interface

A web interface is being developed via WebAssembly. It is currently not working.

Debug

In order to obtain a more verbose output, it is possible to define the logging level via the GFILE_LOG environment variable.

Example: export GFILE_LOG="TRACE" See function setupLogger in main.go for more information
