static ip

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

Code:

ifconfig

and

Code:

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


eth1 Link encap:Ethernet HWaddr 00:0d:88:21:da:92

Router address internet IP address 192.168.15.2
IP address 192.168.1.1

route -nee
Destination Gateway Genmask Flags Metric Ref Use Iface MSS Window irtt
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 0 0 0
0.0.0.0 192.168.1.1 0.0.0.0 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

Code:

auto eth0
iface eth0 inet static
    address 192.168.[B][COLOR="Red"]1[/COLOR][/B].100
    netmask 255.255.255.0
    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
