Debian not saving ethernet configuration

dpeterson3 · 07-17-2009, 08:43 AM

I have my Debian box setup with a static ip of 192.168.2.80 so I can remote desktop to it. A few weeks ago, I switched the IP to 192.168.0.80 because I needed to use my normal router for something else. Now, every time I boot, I have to change my IP back to 192.168.2.80. I used the network admin to set the address to 192.168.0.80, and it seems to use that configuration from now on. If I try to use network admin to change the IP back, it doesn't work. How can I make my original configuration stick?

The GUI tools for configuring networks generally aren't too good.

I found the easiest and most reliable way is to edit /etc/network/interfaces directly.
Eg:

Code:

iface eth0 inet static
broadcast 192.168.2.255
address   192.168.2.80
netmask   255.255.255.0
gateway   IP.OF.YOUR.ROUTER

Then

Code:

sudo /etc/init.d/networking     restart

Thanks. Supprised I didn't think of that myself. Now that I think about it, that was the way I got it messed up in the first place.
