Arper

A network utility and library for discovering network device via ARP scans, including vendor names.

Quick Start

Get arper:

$ go get github.com/jondot/arper/...

Then run it (make sure to use sudo) and wait 10 seconds:

$ sudo arper
192.168.50.1	00:16:0a:xx:xx:xx	SWEEX Europe BV
192.168.99.6	08:00:27:xx:xx:xx	Cadmus Computer Systems
192.168.50.42	00:26:73:xx:xx:xx	RICOH COMPANY,LTD.
192.168.99.100	08:00:27:xx:xx:xx	Cadmus Computer Systems

Options are quite simple:

$ arper --help
Usage of arper:
  -timeout uint
    	Timeout in seconds (default 10)
  -verbose
    	Verbose logging

As a Library

A better use for arper is as a library

import(
	"github.com/jondot/arper"
)
arp, err := arper.New()
if err != nil {
  fmt.Printf("Error: %v", err)
  os.Exit(1)
}

devices, err := arp.Scan(time.Second * time.Duration(*timeout))

Since ARP scans are fuzzy, you can scan again by supplying a different duration, have your own repeat scan intervals and so on with the same arper instance.
