ARP

A very simple package with a single public function; Sniff(). Sniff takes a list of devices to listen for and a network interface. When a device makes an ARP request its action method is called.

Example

package main

import (
	"fmt"

	"github.com/willis7/arp"
)

func Shout() {
	fmt.Println("Hello")
}

func main() {
	helloFn := arp.ActionerFunc(Shout)

	devs := []arp.Device{{"Hello", "ab:cd:ef:12:34:56", helloFn }}

	arp.Sniff(devs, "en0")
}

In the code above, when an ARP request is detected coming from mac address ab:cd:ef:12:34:56 the helloFn ActionFunc is called which is a wrapper around Shout. Hello simply prints Hello to stdout.
