How to change a machine name?

[kitepilot at kitepilot.com]

Joe, 'changing a name' can be a *CAN* of worms.
Do:
find /etc/ -type f -exec grep -l "$(hostname)" "{}" \;
and that will tell you all the files where the current hostname is 
hardcoded.
Yes, it *DOES* get hardcoded in multiple places. 

Now you can:
for FILE in $(find /etc/ -type f -exec grep -l "$(hostname)" "{}" \;);do
      sed -i.B4_HOSTNAME_CHANGE -e "s/$(hostname)/mynewname/g" "${FILE}"
done 

And finally:
hostname mynewname
That should do the trick, YMMV.
Free advice, can't sue me!   :) 

As for the IP, why do you want to change the IP?
There are multiple ways to accomplish that (persistently) and most depend on 
the distro flavor.
You could even use your router for that purpose, but why?
