Changing IP Address from DHCP to Static IP in Ubuntu
Hello… this will remind me.. hihhihi…
ok, lets now open the interfaces file
$ sudo vim /etc/network/interfaces
for the default, you’ll see in the file
auto eth0
iface eth0 inet dhcp
ok, now we’re going to change the way from DHCP to Static, just enter these text, and suit to your needs
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
now, set the DNS setting by open and edit the file
$ sudo vim /etc/resolv.conf
on the line “name server xxx.xxx.xxx.xxx” replace the x with your nameserver,
you can do ifconfig /all to find out what they are.
ok, thats all… the last u have to do is, removing the DHCP client and Restart the Net-Interface
$ sudo apt-get remove dhcp-client
& restart the network
$ sudo /etc/init.d/networking restart
See you…..
