1. List 3 different protocols that appear in the protocol column in the unfiltered packet-listing window in step 7 above.
From the Wireshark capture, we can immediately see an STP protocol, TCP protocols, a UDP protocol, and HTTP protocols.
2. How long did it take from when the HTTP GET message was sent until the HTTP OK reply was received? (By default, the value of the Time column in the packet listing window is the amount of time, in seconds, since Wireshark tracing began. To display the Time field in time-of-day format, select the Wireshark View pull down menu, then select Time Display Format, then select Time-of-day.)
To determine the time it took, we look at the get request and the HTTP OK arrival times and subtract the GET from the OK.
So, 3.431008000 seconds – 3.398919000 seconds = 0.032089 seconds.
3. What is the Internet address of the gaia.cs.umass.edu (also known as wwwnet. cs.umass.edu)? What is the Internet address of your computer?
The Internet address of gaia.cs.umass.edu is 128.119.245.12.
The Internet address of my computer is 10.33.41.177
4. Print the two HTTP messages (GET and OK) referred to in question 2 above. To do so, select Print from the Wireshark File command menu, and select the “Selected Packet Only” and “Print as displayed” radial buttons, and then click OK.
