On the Linux box: To capture network traffic, we will use a tool called a network analyzer or packet sniffer named wireshark. (The program ping sends out an ICMP Echo Request to a given IP address.) Note that allowing users to capture network activity is a security risk only the superuser is permitted to do so. In this step, you will capture the network activity the ping program generates between your computer and the computer you are pinging. If you do not, type ipconfig /release, then ipconfig /renew. Type ipconfig and see if you have an IP address on the 192.168.33 network.From the start menu, search for and run cmd.exe.Remove the orange cable and plug in the white cable into the same ethernet port.Click all the OK/Apply buttons to get out of all the dialog boxes.Click Obtain DNS server address automatically.Click Obtain an IP address automatically.*** Write down in your lab report all the information in that dialog box.Go to: Start Menu -> Control Panel -> View network status and tasks -> Local area connection -> Properties -> Internet Protocol Version 4 -> Properties.Log in using your campus-wide Windoze login / password. Make sure the machine is on the orange network.

Boot the computer next to you into Windoze.

I recommend you google for 'ip addr output'. You will probably have to use google to learn more about what you are looking at. Then, in that document, write notes explaining as much as you can about what you see there.

*** For the one interface being used, copy the output from ip addr to your document that you are going to submit for this lab.

Figure out which interface is being used by the computer.

These computers have multiple ethernet NICs.

If it is also connected to the orange network, remove that ethernet cable.

Make sure your computer is only plugged in to the white ethernet cable.

(In fact, I recommend you find Terminal Emulator and then drag it onto the desktop or launchbar, so you can more easily run it in the future.) Open a terminal window: Accessories -> Terminal Emulator.(The following is done on the Xubuntu (Linux) machine.).For the pair of you, boot one machine into the Xubuntu operating system from the flash drive.gets you started with the network monitoring program wireshark.investigate the interface information stored on a Linux box and Windows box, and,.I recommend you use a google doc to record your answers. *** = write down and submit answers to these questions/problems.
