What is it in this TCP segment that identifies the segment as a SYN segment? Will the TCP receiver in this session be able to use Selective Acknowledgments (allowing TCP to function a bit more like a “selective repeat” receiver, see section 3.4.5 in the text)? Sequence Number (raw): 37731822 The SYN flag is set to 1 and it indicates that this segment is a SYN segment.

Number with respect to the starting sequence number of this TCP session.). Also note that this is not the relative sequence Remember there is no such thing as a “packet number” in TCP or UDP as you know, there are sequence numbers in TCP and that’s what we’re after here. What is the sequence number of the TCP SYN segment that is used to initiate the TCP connection between the client computer and gaia.cs.? (Note: this is the “raw” sequence number carried in the TCP segment itself it is NOT the packet # in the “No.” column in the Wireshark window. What is the IP address of gaia.cs.? On what port number is it sending and receiving TCP segments for this connection? Destination: Ip :128.119.245.12 Port: 80 3.

What is the IP address and TCP port number used by the client computer (source) that is transferring the alice.txt file to gaia.cs.? To answer this question, it’s probably easiest to select an HTTP message and explore the details of the TCP packet used to carry this HTTP message, using the “details of the selected packet header window” (refer to Figure 2 in the “Getting Started with Wireshark” Lab if you’re uncertain about the Wireshark windows).
