no internet with static IP in intrepid

[p-stone]

Hi all

I've installed intrepid and find myself unable to surf the internet with a static IP. When in DHCP mode I pick up an IP and surf just fine, however it's frustrating when my DHCP lease expires and all the other machines on my network lose my nfs share. In hardy and previous releases I simply gave myself a static IP and everything worked fine. Now however I can only access my internal network. I can ping all internal machines, as well as my router, however I cannot reach any external websites. If I try and ping yahoo.com for example I get an unknown host error. If I ping yahoo's IP I get "connect: Network is unreachable" For my static settings I initially left the DNS entry blank, however I've also tried setting the IPs used by opendns, to no effect. Has anyone experienced something similar?

Thanks

Update, I think it's got to do with how I'm going about configuring the settings, I'm getting some really weird behavior from the network manager. When I created the connection I gave it an IP of 192.168.1.103, subnet 255.255.255.0, GW 192.168.1.1 and opendns 208.67.222.222, 208.67.220.220
however, when I went back to try and edit them again, my IP and DNS were the same but my subnet had changed to 24 and my gateway was 0.0.0.0. I also had an old configuration that I'd deleted come back. I wasn't prompted for my admin password at any point when I was making these changes, which I found odd. Again, with static I can operate on my internal network but no internet, DHCP all is well.

Thanks again

I think I'm having a similar problem? I'm unable to assign a static address. I enter the via the network manager applet--but it gets reset at the next boot.

I am having exactly the same problem in Gnome Ubuntu 8.10. The subnet mask changes to "24" when I entered "255.255.255.0" and then the static address does not save. After reboot it goes back to dhcp. So this bug is not just in kubuntu.

Looks like this can be done with manual editing

Edit /etc/network/interfaces like this (adjust to your addresses)

auto lo eth0
iface lo inet loopback

iface eth0 inet static
  address 192.168.22.55
  netmask 255.255.255.0
  gateway 192.168.22.1

Then restart networking ...

/etc/init.d/networking restart

Also see man interfaces.
