    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

    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
    route -nee

    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

    eth1 Link encap:Ethernet HWaddr 00:0d:88:21:da:92
    inet addr: Bcast: Mask:

    route -nee
    Destination Gateway Genmask Flags Metric Ref Use Iface MSS Window irtt U 0 0 0 eth1 0 0 0 UG 100 0 0 eth1 0 0 0

    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.[B][COLOR="Red"]1[/COLOR][/B].100
        network 192.168.[B][COLOR="Red"]1[/COLOR][/B].0
        broadcast 192.168.[B][COLOR="Red"]1[/COLOR][/B].255
        gateway 192.168.[B][COLOR="Red"]1[/COLOR][/B].1
    in /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
