Debian based: CLI networking configuration

For this example demonstration we will use:

Router IP address - 192.168.0.1

Subnet - 255.255.255.248

PC IP address - 192.168.0.4

PC network device - eth0

DNS server - 8.8.8.8

A. Using CLI commands to configure static IP, subet & default gateway:

1. sudo ifconfig -a eth0 192.168.0.4 netmask 255.255.255.248

2. sudo route add default gw 192.168.0.1

B. Using CLI command to configure dynamic IP, subnet & default gateway:

1. sudo dhclient eth0

C. Using Text editor to configure static IP, subnet & default gateway:

1. Open using a Text editor "/etc/network/interfaces" with Root privileges

2. In the end of the file add:

auto eth0

iface eth0 inet static

address 192.168.0.4

netmask 255.255.255.248

gateway 192.168.0.1

3. Save & close the text editor

4. Stop the network service: sudo /etc/init.d/networking stop

5. Start the network service: sudo /etc/init.d/networking start

D. Using a Text edit to configure dynamic IP, subnet & default gateway:

1. Open using a Text editor "/etc/network/interfaces" with Root privileges

2. In the end of the file add:

auto eth0

iface eth0 inet dhcp

3. Save & close the text editor

4. Stop the network service: sudo /etc/init.d/networking stop

5. Start the network service: sudo /etc/init.d/networking start

E. Using a Text editor to configure DNS servers:

1. Open using a Text editor "/etc/resolve.conf" with Root privileges

2. In the end of the file add:

nameserver 192.168.0.1

nameserver 8.8.8.8

3. Save & close the text editor

Hope that it will help somebody.
