# ARP Library
This package implements two function of "WhoHas" and "IsAt" functions and also listen for arp packets using pcap.
An ARP spoofer has implemented as a test.
```
//Ask who has 192.168.0.1
packetBytes := arp.WhoHas(net.ParseIP("192.168.0.1"))
//Tell to target that 192.168.0.1 is at my desired mac
var fakeDevice := arp.Address{
IP:net.ParseIP("192.168.0.1"),
HardwareAddr : net.ParseMAC("xx:xx:xx:xx:xx")
}
var target := arp.Address{
IP:net.ParseIP("192.168.0.2"),
HardwareAddr : net.ParseMAC("yy:yy:yy:yy:yy")
}
packetBytes = arp.IsAt(fakeDevice,target)
//Listen to incoming arp packets
handler, err := pcap.OpenLive("eth0", 65535, true, pcap.BlockForever)
if err != nil {
log.Fatal(err)
}
defer handler.Close()
arp.Listen(handler, func(srcAddress arp.Address,replyTo arp.Address) {
log.Info("%s is at %s \n",srcAddress.IP.String(),srcAddress.HardwareAddr.String())
}, func(ip net.IP,replyTo arp.Address) {
log.Info("Who has %s? Tell %s \n",ip.String(),replyTo.IP.String())
})
```
