Summary

In this Lab, I used the ping command along with Wireshark to capture the ICMP requests and replies going out of and coming into the NIC of my laptop, and recording some of the information displayed by the packets.

Useful Commands/Instructions

• The ping command was useful in this lab for capturing ICMP requests and replies in Wireshark.
• Wireshark was a useful tool in this lab as it captures packets coming into and out of the NIC.

Problems I Ran Into

• Since I am on the Champlain Wi-Fi network, the ping command to the default gateway was unable to successfully execute, resulting in a request timed out, so only request packets were recorded in Wireshark for that ping. There wasn't anything that could be done to fix this, so all that needed to be recorded for that portion of the lab was the information for the requests.

Useful Information/Lab Specifics

• Wireshark is network analyzer that can be used to monitor your network traffic on the device you are using. It also tells you information about the packets that it captures. To use it with ping, you start capturing, then execute the ping command, then stop capturing.
• The way that I think ping work is, when you ping a device, your device sends four packets to the destination IP address, that destination replies to each packet it receives by sending a packet back to the sender.
