Moving from DHCP to Static

Simdude90015 · 08-02-2006, 07:16 PM

I've just installed debian on a few older machines for my first attempt at a cluster. On one of the machines, the installer configured the ethernet interface using DHCP, but I want to set the IP address to something static (namely 192.168.0.41)

Also, there doesnt seem to be a /dev/eth0 file... or any /dev/eth* files at all... whats up with this?

Linux kernel version 2.4.27-2-386

Thanks for any help

This thread should really be in Linux - Networking

- I use Ubuntu rather than Debian, but they are similar so I think that this should apply.

There are no /etc/eth* device files needed, therefore they are not created any more. If you want to see what interfaces are detected you can use

Code:

cat /proc/net/dev

The file with dhcp / static IP address information is in
/etc/network/interfaces

You will currently have an entry

Code:

iface eth0 inet dhcp

which should be replaced with

Code:

iface eth1 inet static
address 192.168.1.2
netmask 255.255.255.0
gateway 192.168.1.1

(replace the addresses / mask with your details).

You could remove the dhcp-client package, but it shouldn't do any harm leaving it there.

Other things you need to change are DNS entries which should be added to /etc/resolv.conf
e.g.

Code:

nameserver 192.168.1.1

Add entries for all your DNS servers.

Then restart your network using

Code:

/etc/init.d/networking restart

I think that's everything, if you have a single port.

Thanks penguintutor!

And Yeah, After I submitted it, I found out that there was a networking section... sorry. But thanks for moving it!
