What is the sequence number of the SYNACK segment sent by gaia.cs.umass.edu to the client computer in reply to the SYN? What is the value of the ACKnowledgement number in the SYNACK segment? How did gaia.cs.umass.edu determine that value? What is it in the segment that identifies the segment as a SYNACK segment? Provide a screen shot that displays the SYN and ACK field values.

Now, locate the packet containing the HTTP GET command. Note that in order to find the packet, look for the GET command in the INFO column of the Cloudshark packet listing. What is the TCP Length? (Look for Len: in the Transmission Control Protocol headers in the center white section of CloudShark, not the Length Column in the green part). Now, find the ACK from the server back to the workstation (should be the next packet in the trace). What is the ACK number in the ACKnowledgement? Explain the relationship between this number and the TCP Length (above). Provide a screen shot or two showing these values.

Packet #12 in the trace starts the transfer of the upload of Alice.txt to the server. Look at the next several TCP Segments that go FROM THE CLIENT TO THE SERVER. Look into the details section of Cloudshark for each of these segments and identify the TCP Packet length of each of the next six (6) TCP segments that go from the client to the server. What are these lengths? Note, dont simply report the full Ethernet frame length that is what you see in packet top section of Cloudshark (in green). Instead go to the details section of Cloudshark (in white) and report the TCP Packet length. Provide a screen shot of one of these segments.
