Overview

In Lab 2-2 we pinged devices and used Wireshark to view the source and destination of the request and response packets from those pings.

Commands/Instructions

Default Gateway

The IP address of the default gateway is 192.168.1.250. The default gateway is the default location where packets are sent to so they can they be sent outside of the local network.

MAC Address

An identifying address for network devices that is set by the manufacturer.

Questions

What is the MAC address of your workstation's NIC? What is the MAC address of the Default Gateway Router interface (NIC)?

The MAC address of my workstation is 08:00:27:e8:4a:db, and the MAC address of the Default Gateway Router is 00:00:5e:00:01:ca.

Compare the source/destination MAC address with the MAC addresses captured above. Are they the same or different? Discuss why they are the same or different.

The MAC addresses are the same. The workstation MAC address is the same since I the lab was done using the same device throughout, so the device sending the pings never changed. The destination MAC address stayed the same since the workstation does not have a direct connection to www.timeslive.co.za, and so it data must be transported through multiple place, which requires it starts at the default gateway.

Troubleshooting

Kali Linux VM Wouldn't Log In

• Doubled the RAM and processors available to the VM: Did not work
• Reinstalled the VM: Worked

Couldn't Run Wireshark .EXE

• Kali Linux has a pre-installed version of Wireshark, which can be run as an app: Worked

The MAC address of the workstation, the source of the request ping (blue)

The MAC address of the workstation, the destination of the response ping (red)

The MAC address of source of the response ping, not the origin of the packet, but the last device necessary to deliver the packet (blue)

The IP address of www.timeslive.co.za (red)

The MAC address of the default gateway, the destination of the ping, since the packet must be sent through the default gateway to then travel to end destination (red)

The MAC address of the workstation, the source of the request ping (blue)
