Host discovery in a network

Whisper

Server/host discovery in a network

Building

make all

It will create two binaries, bin/client and bin/server

Running

Run the client executable on a machine that should be discovered, and the server on a machine to monitor hosts on the same network. Once running, clients send a periodic ping in broadcast mode, with a signature payload, and the server picks it up.

To query the the server for hosts the network, send GET request to it's at http://{server-IP}:46790 The server will respond with a payload of listed hosts.

e.g.

{
   "192.168.1.10!:55460":{
      "Host":{
         "IP":"192.168.1.101",
         "Port":55460,
         "Zone":""
      },
      "LastPing":"2016-06-27T19:10:14.675370062+02:00",
      "Payload":{
         "os":"darwin",
         "arch":"amd64"
      }
   }
}
