Pcap_check_tcp_handshake.py unit test is failing

I have done tasks mentioned in milestone 3. I have mapped the ip addresses also, I have listed the ports.
While listing the ports there were a lot of connections as TCP with my IP address. So I didnot write the ACKs in the file.
Please tell me where am I going wrong.
I can share the screenshots personally if you want.

Find out which protocol you should be looking for and use filters on wireshark to look for the packets and make sure you are using the correct filter
