Seting manual IP Addres pada kubuntu 9.04

Caranya :

1) Disable Network Manager:
sudo update-rc.d -f NetworkManager remove
sudo apt-get remove network-manage

2) Edit /etc/network/interfaces:
auto lo eth0
iface lo inet loopback

iface eth0 inet static
address 10.10.1.25
netmask 255.0.0.0
gateway 10.10.1.1

dns-domain 192.168.2.1

3) Edit /etc/resolv.conf:
domain test-kubuntu
nameserver 10.10.1.1

4) Restart networking:
sudo /etc/init.d/networking restart

Change Ubuntu Server from DHCP to a Static IP Address
If the Ubuntu Server installer has set your server to use DHCP, you will want
to change it to a static IP address so that people can actually use it.
Changing this setting without a GUI will require some text editing, but that’s
classic linux, right?
Let’s open up the /etc/network/interfaces file. I’m going to use vi, but you
can choose a different editor
sudo vi /etc/network/interfaces
For the primary interface, which is usually eth0, you will see these lines:
auto eth0
iface eth0 inet dhcp
As you can see, it’s using DHCP right now. We are going to change dhcp to
static, and then there are a number of options that should be added below it.
Obviously you’d customize this to your network.
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 we’ll need to add in the DNS settings by editing the resolv.conf file:
sudo vi /etc/resolv.conf
On the line ‘name server xxx.xxx.xxx.xxx’ replace the x with the IP of your
name server.
(You can do ifconfig /all to find out what they are)
You need to also remove the dhcp client for this to stick (thanks to Peter for
noticing).
You might need to remove dhcp-client3 instead.
sudo apt-get remove dhcp-client
Now we’ll just need to restart the networking components:
sudo /etc/init.d/networking restart
Ping www.google.com. If you get a response, name resolution is working(unless
of course if google is in your hosts file).
Really pretty simple.
Updated Thanks to Nickname007 in the comments for noting that I forgot the DNS
entries in the guide.
