Wireshark in User Mode

If you are running Ubuntu or Linux Mint, the wireshark may not list all the interfaces except bluetooth. There is a small workaround for enabling all the interfaces within wireshark

To install wireshark
$ sudo apt install wireshark

Checking for all the interfaces
$] ifconfig -a 
eth0      Link encap:Ethernet  HWaddr b4:b5:2f:90:41:98  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          RX bytes:591668376 (591.6 MB)  TX bytes:41118839 (41.1 MB)

To check the interfaces shown by the dumpcap

$] dumpcap -D -M (following line is the output)
1. bluetooth0 4 network

Enable the following commands in linux to make it work.
$] sudo groupadd wireshark
$] sudo usermod -a -G wireshark $USER
$] sudo chgrp wireshark /usr/bin/dumpcap
$] sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
$] dumpcap -D -M (following is the output)
dumpcap
dumpcap
