Configure Your Network

To configure your network you need to be root by using the su command
also you need some information about your network like

your IP, subnet mask , DNS IP , Gateway IP

NOTE : our common networks use its routers as DNS & GateWay in the same time
but some ISP provide it's own DNS.

in this article we will use the fellowing data as example :

IP : 192.168.1.200
SUBMASK : 255.255.255.0
GATEWAY : 192.168.1.1

DNS : 192.168.1.1 <---- your ISP may provide you with other IP

===============================
We will need to edit 2 files :

1. network card configration file : /etc/sysconfig/network-scripts/ifcfg-eth0
2. DNS configration file : /etc/resolv.conf

===============================
Frist : Edit Network configartion file
===============================
using the command :

vi /etc/sysconfig/network-scripts/ifcfg-eth0

enter the fellowing lines :
IPADDR=192.168.1.200
NETMASK=255.255.255.0
GATEWAY=192.168.1.1

the change the fellowing line to :

BOOTPROTO=none <---- "if not exist create it" so your file maybe like the image

then save & exit
===============================
Second : Edit DNS configration file
===============================
vi /etc/resolv.conf

enter the fellowing line

nameserver 192.168.1.1

NOTE : every line have one DNS IP and you may add mor than one like the fellowing image i add 3 DNS servers

then save & exit.

to changes take effect you must restart your network deamon

/etc/init.d/network restart
