Configurate the network interface

1. Configurate the IP-address
# sudo nano /etc/network/interfaces/

config example:
iface eth0 inet static
address 192.168.0.100
netmask 255.255.255.0
gateway192.168.0.1

After the configuration is done restart the network interface:
# sudo /etc/init.d/networking restart

2. Configurate the DNS
# sudo nano /etc/reslov.conf

config example:
nameserver 192.168.0.2
nameserver 192.168.0.3
