[lug] Re: stupid question about domains

The thing I never figured out was what to do w/ DHCP.  I don't want to assign each lab a static IP -- this method seems to require it. 

I am willing to try this if I can keep DHCP.  There are computers all over this building and I don't want to have to keep an IP chart in a notebook somewhere. 

Thanks for the directions.  I hope it's this simple.

Kari,

It sounds like what you want to do is just mount /home to a san in your
workstation's /etc/fstab files.

In your lab this is very very easily accomplished via nfs. You were on
the right track about your domain. However in your lab you don't really
need a domain to exist.

Take 1 server and make it a file server. Any of them would work so long
as there is enough space. Rather than fuss with domain controllers and
dns and rdns simply use /etc/hosts to identify the servers to eachother
in your lab.

Make your domain, sample.com

You have :

fileserver.sample.com
station1.sample.com
station2.sample.com

In fileserver's /etc/hosts, you should see this

192.168.1.3 station1.sample.com station1
192.168.1.4 station2.sample.com station2
.. and so on for the rest of your nodes.

Every node should have this in /etc/hosts :

192.168.1.12 fileserver.sample.com fileserver

Next , verify portmap and nfs-utils are installed on all nodes and
server. Make sure nfs starts.

In your file server's /etc/exports file add this line for every node
/home node1(rw,no_root_squash)

You could also break up the /home partition on your file server to go
by groups, nodes , however you want to set it up.

Since you are a school we can provide you with a free nfs-mountable
co-located san up to 15 gb. Feel free to get in touch if you could use
one.
