Wireshark on Ubuntu 11.10 No Interfaces


When installing Wireshark on Ubuntu I’ve run across the issue of no interfaces. Below are the steps to revolve that issue.

Install the setcap executable
$ sudo apt-get install libcap2-bin

Create wireshark group
$ sudo groupadd wireshark

Add your user name to group wireshark
$ sudo usermod -a -G wireshark YOUR_USER_NAME

Change the dumpcap directory to group wireshark
$ sudo chgrp wireshark /usr/bin/dumpcap

Change mode to 750
$ sudo chmod 750 /usr/bin/dumpcap

Grant capabilities with setcap
$ sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

Verify the change
$ sudo getcap /usr/bin/dumpcap

  7. According its help documents, only two steps:
    sudo dpkg-reconfigure wireshark-common
    sudo usermod -G wireshark -a $USER

    then reboot
