Our IBM/BitNet machines have UMD names: UMDA thru UMDD. Our Internet machines have UMD names: UMD2, UMD7, etc. So, what should the name of our Sperry (which is on both nets) be? We respond to the names: UMDU.BITNET and UMD2.UMD.EDU both.* 2. Routing. If your machine is called AAA.BITNET and BBB.XXX.EDU then (assuming the remote side has enough smarts to handle two name spaces without . suffixes - UMD2 does this) you can control which path mail from a particular person uses by giving him one name or the other. This is really off-the-top-of-the-head stuff, and I would welcome any other reasonable surmises why one would want to do this. It would help to have a mantra of them to chant when I have to look at the kluge mail code... Ben Cranston POSTMASTER@UMD2 * Although (again due to politics) we also respond to UMD2.BITNET. Don't ask. It's a REAL kluge since BitNet doesn't have aliases. We sort of lie to UMDA and tell it that there are *two* machines down that wire. There are also masses of kluges at UMD2 to handle the equivalence of the names (AND the fact that other BitNet sites don't know this equivalence). It also breaks a lot - i.e. my kluges are not yet quite robust enough. Also note there used to be a UMDU.ARPA alias back in the days of .ARPA names but it seems to have gone away at some point... -- Ben Cranston ...{seismo!umcp-cs,ihnp4!rlgvax}!cvl!umd5!zben zben@umd2.ARPA
