[comp.mail.uucp] Internet Paths in UUCP Maps -- Can We Stop?

csg@pyramid.pyramid.com (Carl S. Gutekunst) (06/02/88)

I'd like to make a plea with all sites to stop listing Internet connections on
their UUCP Maps. The problem is that it is getting increasingly difficult for
me to generate meaningful pathalias output. I can twiddle the numbers to make
the paths come out right, but this is becoming tedious. In this day of domains
and smail, there is simply no good reason for any site to list their Internet
connections on the UUCP Maps; domains handle the routing. Isn't this the whole
reason domains were created, to simplify the maps? 

The worst "offenders" for us are Rutgers and Ames; I have discussed this with
their respective administrations and they felt they wanted the map entries
kept as is. But why? I mean, there is this nice bunch of lines in D.top: 

	rutgers	.uucp
	rutgers	.arpa, .com, .gov, .mil, .edu, .org, .net, .us
	rutgers	.de, .no, .nz
	rutgers	.bitnet

That tells me everything I need to know about rutgers connections. Given this,
why does any site need to show explicit names in their list of links?

Comments? Mel?

Carl,

I have read through this 4 or 5 times and still cannot figure out exactly
what you are complaining about.  What do you mean by "Internet connections"?

eh?  why do you need to twiddle anything?  Maybe if you give an example
of what sorts of things you're having troubles with?

Well.  That's not the real reason that domains were created, but it *was* the
reason we push domains for the uucp world so I'll let it stand as is.

Well, I was curious and took a quick look in the map to see what was
going on.  Do you perhaps mean the section of stuff listed as "TCP/IP"
connections?  What's your problems with that?  If all those connections
are anything like the one they have with us it's done with real UUCP
over TCP connections across the internet.  Regardless of how it's done
I'm sure it'd be invisible to you so what's the problem?

how?  If you take away all of the explicit names then how are we
supposed to generate routes within the net?  If I understand what
you're suggesting correctly the only thing in the site entry would be
the comment section.

Now, I do have a problem with rutgers' entries in general.  In
u.usa.nj.1 they have a number of entries for tiny machines (3b2's).
They don't need to do this -- they can easily cause the mail systems on
those machines to generate domain type addresses EVEN if the machines
are uucp only.  smail is wonderful software and does good things.  You
don't even have to have much of a database on the local machine -- my
home machine has ONE entry, the one giving the route to "ukma" the
local smart-host.

Note that an MX version of sendmail is included in the current
software release (SunOS 4.0).  This has been shipping to thousands
of customers for about a month.

I'm beginning to get a glimmer of what Carl means in the "Second try",
but I still don't think I agree with the underlying assumptions.
Assuming that everyone is being honest (or at least rational) about
the pathalias cost of their links, both UUCP and Internet, then we
must assume that in the absence of pathological behavior the least
cost (i.e., "most efficient") routes are chosen.  

One problem is that the pathalias constants (at the lower numeric levels;
you don't see too many "WEEKLY" entries any more) are stated as "grade of
connection" ("DIRECT", "DEDICATED") but people attempt to derive cost
and speed of delivery from them.

In many cases multiple hop SMTP service is *much* quicker than
single-hop UUCP service, and for people whose network costs are not
(yet) usage-sensitive (hint, hint), it is cheaper as well.

We only list internet connections in the map entry when we have a
TCP-UUCP connection with the site as well, so that mail to 

	<us>!foo!bar

will succeed if we have a TCP-UUCP connection to foo.gov, but

	bar@foo 

will fail since foo is not in our local domain; 

	<us>!foo.gov!bar

is handled by the sendmail config and will succeed in any case.

i run pathalias output through this script:

egrep -v '(\.(com|edu|mil|gov|net|org|arpa|[a-z][a-z])	.*!.*!)|(.\.(com|edu|mil|gov|net|org|arpa|[a-z][a-z])	)'
