I installed Ubuntu Server and the network at our office uses a static IP address and DNS. I edited interfaces and resolv.conf to include the DNS server and static IP address. however, I still can’t ping anything. I know the cable is fine, I know the network is live, I just can’t get Ubuntu on it. I don’t understand what’s the issue. Any ideas for what to try next?

Thanks for the pointers. For some reason wordpress decided to cut the last digit off of the end of a few lines and iponfig - meh - how I didn’t spot that I don’t know.

With regards to /etc/resolv.conf. while I do understand that this is transient, reading my instructions,you’ll find that I only suggest editing it when it doesn’t auto-configure - though its a good point.

tucker. nano comes installed by default in ubuntu. I was trying to write this tutorial to make it easy for people.

Anyway, real programmers use cat

Typo fix:
nameserver : 208.67.222.222
note: the 3rd block is 222

If you’re not familiar enough with vi to use it instead of nano, you probably shouldn’t attempt this on your own.

resolv.conf is an extremely transient file, especially if you are using DHCP. As described here in the second step, you’d want to add:
prepend domain-name-servers 208.67.222.222,208.67.220.220;
To your /etc/dhcp3/dhclient.conf . Your resolv.conf will get wiped out every time you connect through dhcp, and replaced with the dhcp server’s recommendation. Adding a prepend will put the OpenDNS servers first in your generated resolv.conf . More conveniently, instead of changing all your servers to Open DNS, if you have control of your router, change it to use OpenDNS.

The changes to resolv.conf are necessary for a static IP setup; for DHCP, while you need to make those changes to make the DNS change right away, they need to change dhclient.conf (or your router) to make them permanent.

Overall, good post. Did you see if similar instructions were on help.ubuntu.com, and add/merge your instructions?

ipconfig is for windows, ifconfig is for Linux. You might want to update that typo on your post
