[net.news] duplicate UUCP site name 'tut'

long@ittvax.UUCP (H. Morrow Long [Systems Center]) (02/20/85)

	Based on information in the latest uucp and usenet maps I
	believe there are two sites in the UUCP domain named 'tut'.
	Both belong to Universities:

	1.	Tampere University of Technology,
		Computer Systems Laboratory

	2.	New York University
		Courant Mathematics and Computing Laboratory 
		Academic Computer Facility


	In the following output from 'uuhosts', mail path does not
	correspond with the descriptive information:

Somebody at usl noticed that and pointed it out to uucpmap@cbosgd.UUCP
shortly after the UUCP maps were posted in January.

The only place the New York tut is registered is in the entry in the
UUCP map for cmcl2.  Uuhosts naturally assumes uniqueness of names.

I use the arguments "-d cmcl2!tut" with pathalias when I produce the
routing information for ut-sally.  That declares the New York tut dead
and lets the Finnish tut show up.  I do this because it appears to me
that the Finnish tut has clear chronological precedence.  This change
makes getting to many hosts in Europe possible.

A similar problem can be found in usa.nca, where the UC Berkeley
Computer Center "rocks" machines are registered.  The problem is
that they are not only registered with their proper ucb prefixes,
but there are also aliases for names without the prefixes, e.g.:

topaz = ucbtopaz

The name topaz is already registered for a host at Rutgers, and
I seem to recall another duplicate with a host at U. Washington.
(Also, the aliases are all backwards).  The only solution I've
found is to delete these aliases from usa.nca before running pathalias.
