I'm a Linux n00b (very fluent in Windows, though
) that is attempting to set up a (currently) 3-computer cluster. My server node is a Pentium 4, and my client nodes are a Pentium 4 and a Pentium 3 (whatever I have lying around
)
I chose to use OSCAR for my clustering interface and CentOS 5 for my server node OS. Yay. I made it through the installation prerequisites, but when it came to configure the NIC, I got stuck.
I opened the /etc/hosts file, tinkered with it, but something inevitably got screwed up. I can still use the Internet, but it won't let me install OSCAR. Running a system-sanity check returns:
Code:
[root@SurgeonfishR ~]# system-sanity

execute OSCAR.

All I need to know is what the /etc/hosts file should look like for a CentOS 5.4 installation with 1 NIC that is
not connected to a domain (only a LAN). It is connected to a router which in turn is connected to my home network (I don't know what to do about that). The hostname should be surgeonfishr and the IP address should be 192.168.0.150.
I know this question is probably really stupid, but I've logged a total of about 10 hours time on Linux...ever. (And 35000 hours on Windows.)
