OSCAR requires a fully qualified domain name for the head node (which it
then uses to name the rest of the nodes). It does not have to be a "real"
domain name as long as you are on a local subnet, where the names are not
important to anyone else. What I usually do is use
oscarhead.oscardomainfor example, which isn't "legal" but satisfies
OSCAR. You can make it the
domain for your university as well, whatever you like. Like I said, it is
only for your local DNS on your cluster anyway, so it shouldn't cause anyone
else any problems.
So in your case you would need defined (at the lest in /etc/hosts, probably
could do this with "hostname" also)
127.0.0.1 localhost localhost.localdomain
192.168.0.1 marsu marsu.oscardomain
Then oscar would add the later nodes as
192.168.0.2 oscarnode01.oscardomain
I am not certain where the problem comes in when you do not have the domain
name, but I know that has been in the docs for a long time, so I assume it
breaks something if it is not there :)

Hi
I logged in the client node as root. Both the loopback device and the
network adapter (eth0) are active.
I am sending a "gzipped" file of the installation log. I just have one
since I started over from the installation of the mandriva in the server.
Anywau, there is one detail I am not completely confident about. It is
related to the hosts definitions. Before I started the OSCAR installation I
defined the host name using the command "Hostname" as root. But, I did not
specify any hostname during the configuration of the network interfaces.
After, OSCAR was installed, I got these hostnames:
IP address Hostname
127.0.0.1 localhost
192.168.0.1 marsu (this is the name I specify with the hostname command)
192.168.0.2 oscarnode01.oscardomain (this was specified be the OSCAR
installation program)
regards.

You can try to log in, but only root will probably work. You don't need
to log into the client nodes to complete setup, I was just not sure where
you were exactly.
You could log in to the node and check to see that the network card is set
up properly (using "ifconfig"). I suspect that only the loopback device
will be active and not "eth0" (or whichever adapter you chose when you ran
"oscar_install").
If this is not the case, please go into your oscar install directory
(probably /opt/oscar) and do:
tar czvf logs.tgz oscar_install.*
and send the zip file that makes.
