I've installed Red Hat AS 2.1 with the kde gui.  I want to change the host name and ip address.
Where do I go to do that?   Preferably both using gui and using editing of files but either way is ok.

I don't know the gui style in RedHat, but you should find the right infos in :

/etc/hosts
/etc/sysconfig/network

Use the graphical command redhat-config-network - type it from a terminal window.

Install the redhat-config-network rpm from your distro cdroms. If for some reason you cant find it you can download it here -http://altruistic.lbl.gov/mirrors/caos/centos-2/updates/i386/redhat-config-network-1.0.4-0.AS21.1.i386.rpm

owensleftfoot right, you have to install the redhat-config-network in your kde before your can change the network setting.

BTW, Alf666's comment also good to know, it's a console mode (or you can said command mode) method which directly modify the files to make your changes.
use your editor to edit the /etc/sysconfig/ to give the hosts and ip info.

eg /etc/sysconfig/network

[root@linux sysconfig]# more network
NETWORKING=yes
HOSTNAME=host.yourdomain.com                <-- here for host name
GATEWAY=192.168.0.254                            <-- for the gateway

also edit /etc/sysconfig/network-scripts/ifcfg-eth0

[root@linux network-scripts]# more ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.0.255                          <-- the ip of your linux box
IPADDR=192.168.0.1
NETMASK=255.255.0.0
NETWORK=192.168.0.0
ONBOOT=yes

"ifconfig eth0 192.168.0.1  netmask 255.255.255.0" will also change the ip address of your linux box.

so incase the redhat-config-network can't work you still have other way to make it work :)

paullamhkg,
Should be:

[root@linux network-scripts]# more ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.0.255                          
IPADDR=192.168.0.1                                     <-- the ip of your linux box
NETMASK=255.255.0.0
NETWORK=192.168.0.0
ONBOOT=yes
