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

72: workstations of other LON-CAPA software developers.

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