Generate Udp Traffic In Windows

Transcribed image text: 1. Generate some TCP/UDP traffic Windows computer using Wireshark. Find one TCP on a packet (Take a screen shot) and try to answer the following questions - identify the version of IP being used -identify the TTL value in the IP header - identify the type of OS (Windows or Linux) which might be sending this packet - identify the source IP and destination IP address.

Whether you are testing circuit bandwidth, storm control, L2/L3 forwarding, QOS, load balancing, SD WAN application policies, multicast snooping or any of the other myriad things a network engineer does during his day, you need to test with traffic. Hey i am working on an project in which we only send minimum of 10 UDP packets to a server but the problem is that i cant use ten sendto statements as it is quite useless if i try to make an 100 or 1000 packets per second. The problem is that i do not know how to do that. P.s This is an network stresser not an black hat flooder of some kind.

What You Need

  • A Computer running any OS. I wrote the instructions for Windows 7.

Purpose

In this project, you will examine common UDPand TCP traffic with Wireshark. Almost allnetwork traffic relies on these two layer 4protocols, and you must understand them thoroughlyto be an effective networking professional.

Sniff all Traffic with Wireshark

Start Wireshark and begin sniffing alltraffic, as you did in the previous project.

Examining UDP Traffic With WireShark

At the upper left of the Wiresharkwindow, in the 'Filter' bar, type
udp
Press the Enter key on the keyboard.

Packets scroll by, as shown below. Theseare background processes like Windows file-sharingand Dropbox running.

Performing a DNS Lookup

Click Start. In the Search box, typeGenerate Udp Traffic In WindowsCMD and then press the Enter key.

A Command Prompt window opens, as shown below.Type this command, followed by the Enter key:

NSLOOKUP WWW.CCSF.EDU

From the Wireshark menu bar, click Capture, Stop.

Look for these two DNS packets, as shown below:

  • DNS Standard query A WWW.CCSF.EDU
  • DNS Standard query response
You may have to scroll up to find them.

These packets show a request to find the numericalIP address for the domain name WWW.CCSF.EDU andthe response, delivering that request.

Saving the Screen Image

Resize the panes in Wireshark so that onlythese two packets are visible:
  • DNS Standard query A WWW.CCSF.EDU
  • DNS Standard query response
as shown above.

On your keyboard, press the PrntScrn key.

Click Start, type in PAINT, andopen Paint.

Press Ctrl+V to paste in the image of yourdesktop.

YOU MUST SUBMIT WHOLE-DESKTOP IMAGES TO GET FULL CREDIT.

Save the imagewith a filename of 'Proj 2a from YOUR NAME'.

Capturing a TCP Handshake

In Wireshark, click Capture, Start.A box pops up asking if you want to save a capturefile. Click 'Continue wuthout Saving'.

At the upper left of the Wiresharkwindow, in the 'Filter' bar, delete the 'udp'filter and type

tcp.port23
Press the Enter key on the keyboard.

This hides all the packets except TCPto or from port 23.

Making a Telnet Request

In the Command Prompt window,type this command, followed by the Enter key:
TELNET HILLS.CCSF.EDU

Troubleshooting

If telnet is not recognized, you need to install it:

Click Start, 'Control Panel', Programs,'Turn Windows features on or off', and turn on the'Telnet Client'.

You see a screen asking you to log in.Ignore that and switch to the Wireshark window.

You should see the three packets shown below,followed by other packets that aren'timportant right now.

Make sure you see these threepackets in order, as describedin the Info column:

  • [SYN]
  • [SYN/ACK]
  • [ACK]

This is a TCP Handshake, opening a reliablechannel of communication between twodevices.

This particular one lets you use a veryold command-line tool named Telnet,which should have been abandoned decades agobut, unfortunately, still remains in use.

Saving the Screen Image

Resize the panes in Wireshark so that onlythe three handshake packets are visible:
  • [SYN]
  • [SYN/ACK]
  • [ACK]
as shown above.

On your keyboard, press the PrntScrn key.

Windows Udp Socket

Click Start, type in PAINT, andopen Paint.

Press Ctrl+V to paste in the image of yourdesktop.

YOU MUST SUBMIT WHOLE-DESKTOP IMAGES TO GET FULL CREDIT.

Udp Traffic Blocked

Save the imagewith a filename of 'Proj 2b from YOUR NAME'.

Turning In Your Project

Email the images to [email protected] with a subject of'Project 2 from YOUR NAME'.
