README
peerdiscovery
Pure-go library for cross-platform thread-safe local peer discovery using UDP multicast. I needed to use peer discovery for croc and everything I tried had problems, so I made another one.
Install
Make sure you have Go 1.5+.
go get -u github.com/schollz/peerdiscovery
Usage
The following is a code to find the first peer on the local network and print it out.
discoveries, _ := peerdiscovery.Discover(peerdiscovery.Settings{Limit: 1})
for _, d := range discoveries {
fmt.Printf("discovered '%s'\n", d.Address)
}
Here's the output when running on two computers. (Run these gifs in sync by hitting Ctl + F5).

For more examples, see the scanning examples (ipv4 and ipv6) or the docs.
Testing
To test the peer discovery with just one host, one can launch multiple containers. The provided Dockerfile
will run the example code.
Please make sure to enable Docker's IPv6 support if you are using IPv6 for peer discovery.
# Build the container, named peertest
$ docker build -t peertest .
# Execute the following command in multiple terminals
$ docker run -t --rm peertest
Scanning for 10 seconds to find LAN peers
