Wireshark Interfaces

[jacobroecker]

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:

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

Bump for move to its own thread.

sudo apt-get install libcap2-bin wireshark
sudo chgrp admin /usr/bin/dumpcap
sudo chmod 750 /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin+eip /usr/bin/dumpcap
sudo chgrp admin /usr/bin/dumpcap
sudo -s
groupadd -g wireshark
groupadd -l wireshark
sudo usermod -a -G wireshark <yourname>

Thanks folks. I changed this line from

jacobroecker@MooseFlix:~$ sudo chgrp admin /usr/bin/dumpcap

to

jacobroecker@MooseFlix:~$ sudo chgrp myusername /usr/bin/dumpcap

and it works just fine. So, complete code for me

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.
