read() a libtins packet

So I know for a listener to read() a packet the client must write() to that open port's socket.

I've set up a basic server/client example with each implementing the above, and server successfully reading from clients connection.

My problem is I want to read a libtins packet -

IP pktSend = IP("10.0.2.15")/TCP(8080,7070)/RawPDU("Packet Message");

All I've been able to do is sniff the packet server side. But I want to be able to read() its payload. My initial server example taken from - http://ift.tt/1el2JYl - won't read the packet.

I looked into the PacketSender class libtins uses to send packets and it doesn't seem to implement write() at all.

I'm not sure what I'm missing.
