View Full Version : [ubuntu] server: dhcp : no static
December 10th, 2010, 02:49 AM
Fresh install of 10.04.1 server; installs seamlessly; finds network no problem.
However, establishing static connection is driving me batty. Will not take. I've reconfigured "interfaces" file several times. My fingers are numb ifdown-ing and ifup-ing and /etc/init.d/network restart-ing.
I have two files in /etc/network ... interfaces and interfaces~ (one static and the other dhcp). I can switch them in and out of play. The dhcp works and pings out like a champ. static is dead, just dead. Cannot ping router ... nothing.
Just any old suggestion would be much appreciated.
Thanks in advance.

Something I was coming here to look for too. I remember someone once telling me that sometimes the interfaces file isn't what is controlling it. For example, I have a static ip. I am not using Server edition so I can go thru the GUI and see it and set it (which is how I did it). Now, a cat of my interfaces file looks like:
iface lo inet loopback
and that's it. Obviously, this isn't where the control is. So, the answer to both of our problems are probably the same, but I don't know what that answer is. Hopefully, someone will come along soon and point us in the right direction........or tell me I am completely wrong.

Yes, your observation is on point. My box running 10.04 desktop presents the same behavior. Actual changes to the network setup are not reflected in /etc/network/interfaces file.
Hope someone comes along soon with an elegant response.

Removed router from network. Linked up server box directly through modem with static ip. Working well.
Clearly, (or almost clearly), my problem lies with router configuration. Netgear WGR614.
Back for more later ...

If you are going to use a static IP (which I like on my little network) do not forget that you'll have to set up the address of your nameserver (which will usually be the LAN IP of your router, 10.0.0.2 in my case) in /etc/resolv.conf
tred@home:~$ cat /etc/resolv.conf
If you get a LAN IP by dhcp, then dhcp also sets up the nameserver in /etc/resolv.conf so you don't need to.
