static ip

[midgetcoach]

First time Linux user. Been trying to set up Ubuntu Server 8.10. Get to the part of the install that you change from DHCP to a static IP . Make the change and can not get on the internet. Change to look like this (with my numbers).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.0.100
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

Then I lose the net.
Running through a router.
I have been messing with this for a week and still can't get it. I know it has to be something simple I'm missing.

What's your router's internal IP address?

Can you enable DHCP again and then post the outputs of ifconfig and route -nee?

falko,
Thank you for the reply. As you see I am very new to Linux and networking.
I can get the IP from the router and also get the IP that my isp uses to the router. I have not seen or used "route - nee" code before???
On my way out to work now but will post all info back later today.

Here is the info

The system can access the internet for updates at this point.

With the info above can anyone show me what my should static IP look like? Every time I change it to static I lose the internet.

Ok, you're using the 192.168.1.x subnet (instead of 192.168.0.x that I'm using in the tutorial), so you should use

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 192.168.1.1in /etc/network/interfaces.

Thank you that got it ! Now I can move on with my server project. As soon as I get a chance I want to compare what I was doing wrong and to see how it should be done. Looking forward to learning!
Thanks falko
