When one installs F15 (KDE) via the Live ISO, the second part of the install
process asks the user to set the computer network name, ie
localhost@localdomain.
When one changes localhost to another name, it shows up in the DHCP clients
table of my Linksys E4200 router page. I like that.
Where is this name stored ? How does one change what its set to ?
$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Thanks

It may also be in the /etc/sysconfig/network-scripts/ifcfg-* file
or files for the network interfaces in the DHCP_HOSTNAME= line
and perhaps in /etc/hosts as well.

True, but I was just assuming that sane administrators would prefer
the name to be the same everywhere and might want to change it
consistently it all the places it appears :-).

It appears to me that the only way to truly change the hostname of a

That's kind of a standard thing with Linux - very few commands (beyond
mkfs and similar commands) do permanently affect the system. Pretty much
the whole thing is configuration based so any change is going to
require editing a configuration file somewhere.

Not the only way. As others will say, you can set it in a file.
Or, the computer can work it out for itself, when it brings the network
interface up.
When assigned an IP, or bringing up an interface using an IP that you've
preconfigured it with, it does a name lookup to find the name associated
with that IP. This lookup can be answered by your hosts file, or a DNS
server.
e.g. Up comes eth0.
eth0 is 192.168.1.2 (by whatever method that address is assigned)
get the named address for that IP.
finds out it's mailserver.example.com
works out that its hostname is mailserver,
and its domain name is example.com
So, the hosts file (or DNS server) doesn't so much "set" the hostname,
but answers the "Who am I?" question. (Almost the same thing, but not
quite, to be pedantic.)

if using gui both

The system's hostname is set by the HOSTNAME field in
/etc/sysconfig/network
