67: are running - or in the future will run - courses
68: 2) STAND-ALONE - you want this machine to run in 'stand-alone' mode and
69: not be connected to other LON-CAPA machines for now
70: 3) DEVELOPMENT - you want to do software (not content!) development with

72: workstations of other LON-CAPA software developers.
73: 4) RUNNING YOUR OWN CLUSTER - this machine is not in the standard LON-CAPA

215: or "michiganstateuniversity" (too long)
216: or "msuedu" (internet domain, just make it "msu")
217: or "msuphysics" (only if there is a good reason to limit to department
218: - we don't know of one)
219: or "mydomain" (what is that?)
220: Avoid multiple domains at the same institution, even if it means that you
221: have to actually work together with your colleagues. You can still run
222: multiple library servers within the same domain.
223: If this domain is eventually going to be part of the main production
224: cluster, you MUST contact the LON-CAPA group at MSU (loncapa@loncapa.org)
225: to have a domain name assigned, and then use it exactly as given. This is
