68: 2) STAND-ALONE - you want this machine to run in 'stand-alone' mode and

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