5. Handshake Process

SYN - Client sends a server a SYN packet with a random sequence number
SYN-ACK - Server responds with a SYN-ACK packet and increments the sequence number, and sets its own sequence number
Finally the client sends an ACK and acks the server sequence number

Both syns and acks are 32 bit ints
