USAGE

Read sample function

Create MAC addresses for src and dst

srcMAC, _ := net.ParseMAC("00:0c:29:24:fa:a9")
dstMAC, _ := net.ParseMAC("00:50:56:fd:25:2c")

Create IP addresses for src and dst

srcIP = net.ParseIP("172.16.46.185")
dstIP = net.ParseIP("172.217.10.110")

Create host structs, use uint16 for port numbers

srcHost := crznic.NewHost(srcIP, srcMAC, 80)
dstHost := crznic.NewHost(dstIP, dstMAC, 80)

Create crznic handler

crz := crznic.NewCrznic("eth0", srcHost, dstHost, 1)

Send a SYN packet

crz.SendTCPPacket("SYN", "")

Listen for a packet

crz.ReadPacket()
