Since I believe this info is stored under /etc, I did the following...

[ccashion at newdawg etc]$ find . -type f -exec grep newdawg {} \; -print

HOSTNAME=newdawg.3316pony.com
./sysconfig/network

DHCP_HOSTNAME=newdawg.3316pony.com
./sysconfig/networking/profiles/default/ifcfg-eth0

127.0.0.1 newdawg.3316pony.com host localhost.localdomain localhost
./sysconfig/networking/profiles/default/hosts

DHCP_HOSTNAME=newdawg.3316pony.com
./sysconfig/networking/devices/ifcfg-eth0

DHCP_HOSTNAME=newdawg.3316pony.com
./sysconfig/network-scripts/ifcfg-eth0

send host-name "newdawg.3316pony.com";  # temporary RHL ifup addition
./dhclient-eth0.conf

127.0.0.1 newdawg.3316pony.com host localhost.localdomain localhost
./hosts

PonyPrinter|PonyPrinter:rm=newdawg.3316pony.com:rp=PonyPrinter:
./printcap

[ccashion at newdawg etc]$ hostname -f
newdawg.3316pony.com

[ccashion at newdawg etc]$ hostname -d
3316pony.com

[ccashion at newdawg etc]$ domainname
(none)

I had *MANY* lines ending with "Permission denied" which I manually 
removed. Is there a grep option that will remove those lines before
they are printed?
