[plug] Did something dumb.

[Brad Campbell]

G'day all.

I've got a remote box (I have physical access to it, just not for a few days).
It's an Ubuntu server install, so by default it has no root password. Can't su, can't ssh in as root.

I changed the hostname. Now the host name is not listed in /etc/hosts or resolvable via dns.

I can not longer use sudo and believe I have have no way of getting root access on the box short of 
a power cycle and init=/bin/bash

brad at dev-001:~$ sudo -s
sudo: unable to lookup dev-001 via gethostbyname()
brad at dev-001:~$ sudo -s

Bugger huh.. I've not really kept the box up to date so I've been browsing for exploits for anything 
I've got installed, but not found anything. I'm pretty resigned now to wait until I can get physical 
access but just for chuckles I thought I'd let you all know what I did and how I did it to serve as 
a warning.
