can please someone help me with this assignment

1.Using online and any other resources, write a brief summary of how Wireshark is used to manage computer networks.

2. What are the sequence and acknowledgement numbers of the three TCP packets performing the three-way handshake? These packets were exchanged just before the GET request for the web page.

3. Right-click an HTTP packet and select "Follow TCP stream." What are the HTTP header fields in the first client request and the first server response? What are the values in these fields? As an example, in Figure 6.18, one of the client fields is "Host" and the value of the field is "www.ismlab.usf.edu."

4. How many different GET requests did your browser have to make to download the entire page? What were the arguments to these GET requests? For example, in Figure 6.18, the browser made two GET requests. The first request asked for "/htm1101.html" and the second GET request asked for "/favicon.ico." If there are more than five GET requests, only list the arguments for the first five GET requests. (A very convenient way to do this is to first select "Follow TCP stream" and then sort the results by the Info column. All the GET packets will be collected together.)

What is the IP address of your default gateway? This is obtained from ipconfig.

6. What is the MAC address (physical address) of the default gateway identified above? This is obtained from arp -a.

7. Select an HTTP packet. List its source and destination IP addresses as well as source and destination Ethernet addresses.

8. Referring to Figure 6.19 and the information collected in questions 5 and 6 above, what machines does each of these addresses (MAC and IP) refer to? You may be able to relate this to the idea that whereas MAC addresses are hop-by-hop addresses, IP addresses are end-to-end addresses.

9. What are the source and destination port addresses in the selected packet?

10. Look up your etc\services file (in Windows, this file is usually located in C:\Windows\System32\drivers\etc). Which of these ports is a standard port? Paste the entire line from the etc\services file that contains information about this port.
