Switching to STATIC from DHCP

**zeeple** · January 28th, 2009

Hi. I have a newly built machine which I would like to switch from using DHCP to static. I tried doing this with the GUI but everytime I rebooted it it came back up DHCP. I read there is a bug with Network manager, so okay I am fine with doing it via cli.

The /etc/network dir lacks any ifcfg-eth0 that I can find, and there is no /etc/sysconfig to be found. The first thing I need to do is change BOOTPROTO=dhcp to BOOTPROTO=static, but I cannot find where this is done in ubuntu.

Any takers?

Is this of any use? https://help.ubuntu.com/community/StaticDnsWithDhcp

Unfortunately no, that is of no use to me. I need to make the server NOT use dhcp, using the command line, and 'Network Configuration' in the GUI does not work.

Edit /etc/network/interfaces and change the entry for your network device (e.g. eth0) from something like

Code:

auto eth0
iface eth0 inet dhcp

to something like

Code:

iface eth0 inet static
    address 192.168.1.2
    netmask 255.255.255.0
    gateway 192.168.1.1

Thanks! I got a similar answer from the great google in the sky. I'll mark this one solved.

I also have to edit the
/etc/resolv.conf
add nameserver xxx.xxx.xxx
nameserver xxx.xxx.xxx.

One other different thing you could do
Still use HDCP
but reserve the IP address based on the MAC address
therefore therre would be no change on your side
just on the DHCP server side
