LLE10176 : Howto configure a static IP Address on a debian GNU Linux System

Symptom:

You need to change from DHCP to static IP addressing for some reason

Cause:

Static IP addressing is often used on server systems

Solution:

To configure a static IP (an IP that will never change) in debian you must edit the file
/etc/networking/interfaces and put the following:

CODE

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian installation
# (network, broadcast and gateway are optional)
auto eth0


iface eth0 inet static
       address 192.168.1.10
       netmask 255.255.255.0
       network 192.168.1.0
       broadcast 192.168.1.255
       gateway 192.168.1.1


This information can even take DNS information too!
e.g.

allow-hotplug eth0
iface eth0 inet static
 address 192.168.10.11
 netmask 255.255.255.0
 broadcast 192.168.11.255
 gateway 192.168.10.1
 dns-domain lan
 dns-nameservers 192.168.10.6

The reconfiguration of the network CANNOT be done with a dpkg-reconfigure command! This is only supported during installation.

To reconfigure the only thing to do is edit /etc/network/interfaces with a text editor, once
saved /etc/networking/interfaces you can restart networking with /etc/init.d/networking restart.

/etc/init.d/networking stop
/etc/init.d/networking start
/etc/init.d/networking restart

The network configuration package ifupdown delivers the basic networking functionality. The resolvconf package is used to supplement ifupdown to support reconfiguration of network address resolution by automating the writing of /etc/resolv.conf.
