Start a capture and set the filter to ICMP.Brief: You’ll learn to install the latest Wireshark on Ubuntu and other Ubuntu-based distribution in this tutorial. Here is something to try if you want to learn more about Wireshark.

Using Wireshark can be as complex or as simple as you need it to be, there are plenty of advanced features for network experts but those wanting to learn about networks can also benefit from using it. Wireshark will then show a complete copy of the conversation.

Right click on any packet in the exchange and then click on “Follow TCP Stream” (or Follow UDP Stream, Follow SSL Stream depending on the protocol type). If you spot an interesting interaction between two hosts that you want to see in its entirety, then Wireshark has a “follow stream” option. For example, to see all the DNS related traffic that has comes from a particular host, use the filter ip.src=192.168.1.101 and dns where 192.168.1.101 is the source address you want to filter. Wireshark can filter using more advanced criteria than just the protocol type. Other example filters are HTTP, ICMP, SMTP, SMB and so on. ARP is used on a LAN to discover which machine is using a certain IP address. The list will change to only show ARP messages. For example, to see only the ARP (Address Resolution Protocol) message, type arp into the Filter box and click Apply. To see only certain types of network packets, enter the protocol name in the edit box and click Apply. Just below the tool bar is the Filter box. TCP traffic is green, UDP packets are light blue, ARP requests are yellow and DNS traffic is shown in dark blue. Wireshark will begin capturing traffic and displaying it as a color coded list in the main window. On a wired network, it will likely be eth0. Start Wireshark and then click on the network interface you want to use to capture the data.

On Unix-like systems, this invokes command substitution where the output from the which command becomes a parameter for the chmod command, i.e. Note that the quotes marks around the “which dumpcap” aren’t normal single quotes but rather the grave accent character.
