OEL 6.3 system-config-network tool

Question

Hi all,
I just do an installation of OEL 6.3 and wonder while the system-config-network tool looks completely new.
Okay there a lot of things missing like editing hostname, domain, dns and so on.
What do I have to do to get it back under OEL 6.3?
I try the other tools system-config-network-tui and system-config-network-cmd but I can't find the functionality.
What do I have to edit and configure manually when the system-config-network doesn't exists?
kind regards

Red Hat Enterprise Linux 6 and hence Oracle Linux 6 do no longer install a Graphical Desktop when doing a default server installation. If you want a Graphical Desktop you can customize the initial installation, or do it afterwards using the following command:
<pre>
yum groupinstall "X Window System" Desktop "General Purpose Desktop" \
"Graphical Administration Tools" "Legacy X Window System compatibility"
sed -i 's|id:3:initdefault:|id:5:initdefault:|g' /etc/inittab
shutdown -r now
</pre>
However, keep in mind that you can generally run GUI applications using SSH with X forwarding or Tiger VNC without the need to install X Windows Server on the Linux server or running a Graphical Desktop.
Unfortunately, the GUI version of system-config-network under EL 6 requires the Network Manager service, which you might not want to run on a server platform. Anyway, to use the connection editor GUI, the following should do:
<pre>
yum install NetworkManager-gnome
service NetworkManager start
chkconfig NetworkManager on
nm-connection-editor
</pre>
Alternatively, simply edit the following files to configure your DNS, hostname and hosts file:
<pre>
/etc/sysconfig/network
/etc/hosts
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/resolv.conf
service network restart
</pre>
