But if we shouldn't run Wireshark with root privileges, how are we to capture packets? Indeed, due to the complexity and sheer number of its many protocol dissectors, Wireshark is inherently vulnerable to malformed traffic (accidental or otherwise), which may result in denial of service conditions or possibly arbitrary code execution. WIRESHARK CONTAINS OVER ONE POINT FIVE MILLION LINES OF SOURCE CODE. As an older Gentoo Linux ebuild of Wireshark warns: Unfortunately, this often prompts people to simply run Wireshark as root - a bad idea. This is because, by default, raw access to network interfaces (e.g. Many network engineers become dismayed the first time they run Wireshark on a Linux machine and find that they don't have access to any network interfaces. For Windows users, there is some good info in the Wireshark wiki. And there are two ways we can resolve this either launch Wireshark in superuser mode or using sudo.This article focuses on Linux and some UNIXes. 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. Now double click on “wlp2s0” to start capturing. 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.
