And there are two ways we can resolve this either launch Wireshark in superuser mode or using sudo.
In this article, we have learned how to solve the problem when Wireshark cannot detect or list down all interfaces from the Linux system. Here is the screenshot for live capturing. I also have the default wireshark 1.10.14 installed and everytime when trying to open, it only opens the older version. Now double click on “wlp2s0” to start capturing. Hi, I downloaded and installed wireshark 2.2.2 on CentOS 7, however I do not know how to open the GUI for this wireshark. We can try on capturing other interfaces also to see if it’s working. Here is the screenshot for live capturing on interface “enp1s0” See the below screenshot and double-click on the first interface.Īs soon as we double click on the “enp1s0” interface, it starts capturing. Note: “enp1s0” is an Ethernet interface, and “wlp2s0” is a Wi-Fi interface.Īs we see, interfaces are listed down, so let’s try to capture in one interface to see if it’s working or not. Here is the screenshot for the above steps 1 and 2.Īll interfaces are listed down here. Type the command “sudo wireshark” and enter the password for user “rian”. Close Wireshark and enter “ exit” to come out from the root.Ģ. In Linux, running Wireshark in sudo or superuser mode solves the problem. These are the same interfaces that we have seen in the “ ifconfig” command output. Required interfaces are marked with a blue circle. All interfaces are listed down here on the Wireshark home page. Wireshark, a network analysis tool formerly known as Ethereal, captures packets in real time and display them in human-readable format.
