No internet access for static IP

[daktau]

Hi all,
I am in need of a static ip for my ubuntu laptop which is acting as a webserver on my network. I recently changed my router and of course all the host files on the other machines on the network are no longer doing their job.

After having set up a static ip using the 'edit connections' link in the connection status icon I can no longer reach the internet from the ubuntu laptop. I can still see the router and log in to it while using a static IP though, just no internet. Whlst using DHCP the internet works fine but I am after using a static IP.

I have set up the same IP address for the wired network and for the wireless network so the IP address will remain the same which ever method the laptop is using.

Other posts have on the internet seem to solve this problem but I am having difficulty.
I am running Lucid Lynx 10.04.

cheers,
George

Unfortunatly at the moment I don't have a ubuntu computer around, I can't recall when editting the network adapter like you did if you have to fill in a nameserver.

Is the router's ip address located as your nameserver in /etc/resolve.conf?

I just edited the interfaces file - but I don't use network manager.


charles@Thor:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.1.1
dns-search lcl


And resolv.conf

charles@Thor:~$ cat /etc/resolv.conf
search lcl
nameserver 192.168.1.1

Hi

You are based in Bristol, UK ? So i am (south Bristol)!

Sounds like you might have a route problem. Can you ping 8.8.8.8 ?

Using your static IP address, open a terminal and type

Hi,

your router should give your MAC address (and therefore your computer) a static IP. This IP should be outside the DHCP range of the router.

Heheh. I actually had to SSH into my *nix box to grab that info. ;)


Hi,

your router should give your MAC address (and therefore your computer) a static IP. This IP should be outside the DHCP range of the router.

On my router (running dd-wrt) I had to set a reservation inside the dhcp scope. Otherwise set the IP as static outside the DHCP scope (or set it as an exemption).
