Dynamic IP Address Assignment (DHCP Client)

auto eth0
iface eth0 inet dhcp

Static IP Address Assignment

auto eth0
iface eth0 inet static
address 10.0.0.100
netmask 255.255.255.0
gateway 10.0.0.1

Restart

sudo ifup eth0
sudo ifdown eth0

sudo chgrp wireshark /usr/bin/dumpcap
sudo chmod 754 /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

Reihenfolge ist zubedingt zu beachten!
