This means that the target is up and responds back to our ping probes. As you can notice in the image echo reply follows the echo request. Let us now have a look at what a normal ICMP reply message looks like. As you can see in the Internet Control Message Protocol section of packet 1172, this particular message is an ICMP request since it has a value of 8.

Now continue with analyzing the protocol section. You can see the protocol is ICMP, the source IP belongs to our Kali machine. First, let’s take a look at the internet protocol version section. In ICMP, each type of communication is assigned a different value. Now let’s have a look at the captured ICMP packets. Ping -c 5 This is what a ping looks like in Wireshark. You can also send a specific amount of ICMP echo requests by adding a -c flag such as: Then stopped Wireshark capture clicking on stop icon. Then clicked on the start capture icon on Wireshark and typed ping in our terminal. So let’s get started.įirst of all, we opened our Kali terminal and Wireshark side by side and typed ICMP in the filter pane. While actively probing our targeted system, we use two ICMP packets to see if it is up:Īs we already discussed, Wireshark is a network analysis tool that you should be familiar with if you are working in cybersecurity whether you are on the blue or red team side. The Internet Control Message Protocol (ICMP) is a network layer protocol and is essentially used as a management tool that may warn hosts, and system admins about network issues. In today’s blog post we are going to take a look at what an internet control message protocol request and replies can be identified using Wireshark.
