Project Flare aims to bring pervasive signaling infrastructure for NAT traversal with hole punching in libp2p applications. During Phase 0/1, we are alpha testing and collecting metrics using a fixed (limited) relay and a presence service. You can participate in alpha testing by running the flarec binary, with a configuration supplied by the test administrator.

Contact us at libp2p-at-libp2p.io if you want to participate in the ongoing alpha testing.

Checkout the repo and run the flarec binary using the supplied configuration. Please leave the program running in the background for a few days, so that we can collect metrics about hole punching success.

To build:

$ git clone [email protected]:vyzo/libp2p-flare-test.git
$ cd libp2p-flare-test/cmd/flarec
$ go build

To run, first place the config.json file you received into the flarec directory and the just run flarec:

$ cd libp2p-flare-test/cmd/flarec
$ cp /path/to/config.json .
$ ./flarec

The flarec program supports the following command line options:

 -idTCP <path>
  persistent identity key file path for TCP host; defaults to identity-tcp.
 -idUDP <path>
  persistent identity key file path for UDP host; defaults to identity-udp.
 -config <path>
  path to json configuration; defaults to config.json.
 -enableTCP[=false]
  enable (or disable) TCP host; enabled by default.
 -enableUDP[=false]
  enable (or disable) UDP host; enabled by default.
 -nick <nickname>
  nickname for your peer; defaults to user login id.
 -quiet
  reduce logging output to just ERRORs.
 -listPeers
  lists peers that have announced presence and exits
 -eaterTest
  eagerly try to connect to all peers that have announced presence

Running flarec -listPeers will list the current peers that have announced presence and exit. Running flarec -eagerTest will fetch the current peers and attempt to connect with hole punching to all of them.

If you want to run your own testing infrastructure and recruit your own users, you will need two things:

• A limited relay server; see libp2p-relay for implementation.
• The flared daemon, available in this package.

Once you have those two daemons up and running, create a config.json client configuration file (see cmd/flarec/config.go), distribute it to your users, and you are ready to go!
