7. Hands-on practice: WireShark (10 pt., 5 pt. each)
Install Wireshark on your own computer and obtain a screen shot
similar to Figure 1.28 on page
78 of K&R.
Hint: You may want to set “display filter” to filter out non-HTTP
traffic.
a. Capture a HTTP GET request packet. Expand the section of
“Hypertext Transfer Protocol”
for details. Report the connection type.
b. Capture a HTTP response packet with “OK”. Expand the section of
“Hypertext Transfer
Protocol” for details. Report...

I had tried to work with the
wireshark interface and cannot navigate it due to network problems
and cannot find the question solutions, if any one can help with
detailed steps it would be a great help.
Wireshark Lab #2: Ethernet In this lab, we'll investigate the Ethernet protocol and the ARP protocol. Before beginning this lab, you'l1 probably want to review sections 6.4.1 (Link-layer addressing and ARP) and 6.4.2 (Ethernet) in the text. RFC 826 (ftp://ftp.rfc-editor.org/in- notes/std/std37.txt) contains the...

At this stage, you should be a Wireshark expert. Thus, we are
not going to spell out the steps as explicitly as in earlier labs.
In particular, we are not going to provide example screenshots for
all the steps.
1. Start capturing packets in Wireshark and then do
something that will cause your host to send and receive several UDP
packets (Note that DNS is using UDP for communications. You can use
nslookup commands in Lab 4 to generate DNS...

You can refer chapter 2 and chapter 3 of Computer Networking: A
Top-Down approach by Kurose and Ross for the following labs.
Please read the instructions below for submissions.
Upload the shared pcap file (Homework5.pacp) into wireshark.
HTTP
In this lab, we’ll explore several aspects of the HTTP protocol.
Capture packets and filter for http protocol and answer the
following questions. (Hint: Apply http filer)
What version of HTTP version(1.0 or 1.1) is client running and
what is the version...

In this lab, we’ll investigate the 802.11 wireless network
protocol. Follow the instructions and answers questions 7 - 10.
http://gaia.cs.umass.edu/wireshark-labs/wireshark-traces.zip
In this lab, we'll investigate the 802.11 wireless network protocol. Before beginning this lab, you might want to re-read Section 6.3 in the text. Since we l1 be delving a bit deeper into 802.11 than is covered in the text, you might want to check out "A Technical Tutorial on the 802.11Protocol," by Pablo Brenner (Breezecom Communications) http://www.sss-mag.com/pdf802_11tut.pdf, and "Understanding...

In the last module you learned a formula for calculating bit rate, R = b/t, that is the number of bits divided by the time. This formula expresses the number of bits that are transmitted over a circuit in a given period of time. In practice, however, we are not only concerned with the number bits transmitted, but also with the number of data bits transmitted over a circuit. The data bits are those that the sender decides to send...

How to solve Exercises 1?
Project Goal The project will give you some hands-on experience with Nmap. Nmap is a network tool that allows you to scan live hosts and services (open ports), thus, creating a "map" of the network. You will be using Zenmap, a graphical user interface (GUID of Nmap, to investigate several basic types of networl scanning techniques. You can work in teams of two students or alone. Setup: Installing&Using Zenmap Visit nmap.org/download.html to download and install...

Description:
In this assignment, you will be launching a denial of service
attack on a web server. We will be using hping3, a command-line
oriented network security tool inside Kali Linux (an advanced
penetration testing Linux distribution).
Setting up the victim machine
Download the Windows XP virtual machine with WebGoat server
installed, using the following link. We will use this machine as
the victim machine and launch a DoS attack on the WebGoat
server.https://drive.google.com/open?id=0BwCbaZv8DevUejBPWlNHREFVc2s
Open the victim machine and launch...

Project 4-3:
In the following steps, you will learn more about the PING
(Packet Internet Grouper) utility, which can be used on a network
running IPv4 to verify that TCP/IP is configured correctly and
communicating with the network. A ping test is typically the first
thing network professionals try when troubleshooting a TCP/IP
connection problem. For this project, you can use any type of
workstation that's running TCP/IPv4, preferably one connected to
the Internet. The output described in the following...
