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. 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. When you're back in it should let you start sniffing without any fuss about being root.All interfaces are listed down here on the Wireshark home page. Run this: sudo adduser $USER wiresharkĪnd restart or log out. Then you just need to add the user to that group.

Technically any person with access to a computer logged in with a wireshark account will be able to sniff. This is obviously more secure than just letting anybody sniff but does mean there's no password checking. Anybody in that group will be able to sniff without being root.

That's what we're aiming for, so select Yes and hit return.

This will ask you if you want to allow non-root user to be able to sniff. In a terminal (very important that you're in a terminal, not just the Alt+F2 dialogue) run this: sudo dpkg-reconfigure wireshark-common (the '-gnome' part says you want the Wireshark GUI if you dont-youre happy with just the command-line tools, you can drop the '-gnome' part of the package name.) answered 17 Apr 14, 06:31. The bit that normally needs root is the packet collection application and this can be configured to allow certain people to use it without sudo, gksu, etc. If youre happy with the version that CentOS delivers, just do: yum install wireshark-gnome.
