Post subject:  DHCPDICOVER got nothing
I have just gotten my Linode activated. Now it is running Ubuntu 7.04 image. I can connect using Linode shell but not with normal ssh.

I check and it seems that my linode is not getting any DHCP offer despite it is in stock configuration.

Can someone help me with this?

I ran ifdown eth0 and then ifup eth0
No DHCPOFFERS received

I just created a Ubuntu 7.04 image just to see if I would get an ip from the dhcp server. As you can see below I got one:

So if you didn't make any changes to your image, the problem is not on your end. Then there probably is a problem with linodes dhcp server. I would write a support ticket about it if I wouldn't get an answer here within a day. Linodes staff, especially Caker usually reads these forums and answers quickly.

I guess it is just my unluckiness cause I deleted my profile and images then deploy Ubuntu 7.04 via the wizard.

And here is my ifconfig and route -n dump
