# packet sniffer #

Bare bones but functional.

    sudo python ethernetsniffer.py

## Linux only ##

I don't know the cross platform equivalent for `socket.socket(socket.AF_PACKET, socket.SOCK_RAW, socket.ntohs(0x0003))`.

If you do know the equivalent for other operating systems please let me know.

I only know it isn't possible on Windows without third party drivers like PCAP.

Might look into PCAP later.

## implemented ##

- ethernet

- IPv4

- UDP

- DHCP (partially)

## goal ##

Learn how TCP/IP works and can be implemented.
