Installing Wireshark on Ubuntu 12.04 LTS

Installing wireshark on Ubuntu 12.04 LTD and limiting packet capture to one group, in this case the group wireshark. I’m sure you can use these instructions for other debian based distributions.

Although you’ll have to take it as read that I’ve only tested it on Ubuntu, feel free to let me know if it doesn’t and I’ll amend the instructions to suit.

First, we install Wireshark from the terminal.

No interface can be used for capturing in this system with the current configuration

If you run wireshark as a non root user at this stage (see image above), you will get the message “No interface can be used for capturing in this system with the current configuration.”. The following steps will rectify this.

Create the wireshark group.

Add your username to the wireshark group

Change the group  ownership of file dumpcap to wireshark

Change the mode of the file dumpcap to allow execution by the group wireshark

Grant capabilities with setcap

Verify the change

At this point, you will need to log out, then back into Unity (Thanks for Jorge for pointing this out).

You should now be able to run Wireshark as a non-root user, just as long as that user is part on the wireshark group, everything should just work.

  1. don’t works, this appears

    Couldn’t run /usr/bin/dumpcap in child process Permission denied

    opening the wireshark and, no interface can be used…

    please help me

  2. Hi Jorge,

    Try logging out, then back in again before starting wireshark. My fault, I’ll amend the instructions above.


  3. Hi lejurassienfou,

    That command shouldn’t be needed to get wireshark to work, I’m happy for you to explain why it is needed though. If you can persuade me, I’ll happily add it and credit you 🙂



  4. no need to run all those command, all you have to do is open a terminal, type; sudo -s then type your password, then type; wireshark 😉 …. but hey thanks for explaining most of the details here 😀

  5. I don’t understand why is it giving me an error “Wireshark:17402): Gtk-Warning **: cannot open display:

    I tried everything but nothing works…. Anyone have any idea?

  6. I prefer having a bit more control, and using the appropriate group seems a bit more elegant. I’m not that keen on giving everyone read and execute access. Each to their own I suppose.
