    Cool Wireshark Interfaces

    Code:
    jacobroecker@MooseFlix:~$ sudo chgrp admin /usr/bin/dumpcap
    chgrp: invalid group: `admin'
    jacobroecker@MooseFlix:~$ sudo chmod 750 /usr/bin/dumpcap
    jacobroecker@MooseFlix:~$ sudo setcap cap_net_raw,cap_net_admin+eip /usr/bin/dumpcap
    I'm running 12.04. Any help would be appreciated.

    Because of the error above I get:
    Code:
    Couldn't run /usr/bin/dumpcap in child process: Permission denied

    Re: Wireshark Interfaces

    Thanks folks. I changed this line from
    Code:
    jacobroecker@MooseFlix:~$ sudo chgrp admin /usr/bin/dumpcap
    to
    Code:
    jacobroecker@MooseFlix:~$ sudo chgrp myusername /usr/bin/dumpcap
    and it works just fine. So, complete code for me

    Code:
    sudo apt-get install libcap2-bin wireshark
    sudo chgrp myusername /usr/bin/dumpcap
    sudo chmod 750 /usr/bin/dumpcap
    sudo setcap cap_net_raw,cap_net_admin+eip /usr/bin/dumpcap
    Hope this helps anyone else with the same problem in the future

    Thanks folks.
