Ok, so I haven't done it yet.... But I'm thinkin' about it!
Here I'm trying to be Mister Progressive Administrator and install smail.
I thought our modest little network was pretty simple (I still do), but I'm
having mondo trouble getting pathalias to believe it.
The setting:
I have a bunch of vaxen and Suns, all Ethernetted together.
Together they comprise the "fluke" domain. This is the uucp name
we present to the outside world.
Because some machines are administered by different groups of people,
we can have username conflicts. This is easily handled by grouping
the hosts into subdomains. We only have two -- "tc" and "mis".
The problem:
Communicate this configuration to pathalias.
The truth as I see it:
I'm trying to tell pathalias the following:
- We are named "FLUKE.UUCP". (Soon to be FLUKE.COM, but
that's irrelevant here.)
- The "FLUKE" domain comprises the subdomains {.TC, .MIS}.
- The "FLUKE" domain is handled by the host "fluke".
- The "TC.FLUKE" subdomain is also handled by the host "fluke".
- The "MIS.FLUKE" subdomain is handled by the host "evtmis1".
So I claim that:
Mail to user@FLUKE.UUCP should go to ...!fluke!user.
Mail to user@TC.FLUKE.UUCP should go to ...!fluke!user.
Mail to user@MIS.FLUKE.UUCP should go to ...!fluke!evtmis1!user.
Of course, there are other acceptable address formats; I really don't
care what is used, so long as they're correct.
I know what output I want from pathalias -- something sorta like this:
fluke ...!fluke!%s
.fluke ..!fluke!%s
.tc.fluke ...!fluke!%s
.mis.fluke ...!fluke!evtmis1!%s
I've tried many, many permutations of the pathalias input data, but can't come
up with anything which will produce a set of legal paths.
I'm playing with variations on this theme:
fluke .fluke /* host "fluke"
private {.tc, .mis}
.fluke = @{.tc, .mis}(LOCAL)
.mis evtmis1
fluke @evtmis1(LOCAL), microsoft(DIRECT), ...<many other uucp connections>
The $65535 question:
DOES ANYBODY OUT THERE KNOW A STRAIGHTFORWARD WAY TO COMMUNICATE OUR
CONFIGURATION TO PATHALIAS?

To my surprise, I haven't seen an answer to this. Usually, requests of this nature cause an avalanche of replies...... I have taken the liberty of using fluke.com; fluke.uucp is similar. Since smail strips the ".uucp" suffix before resolving the name, using the .com domain is a better example.

Yep. > Mail to user@TC.FLUKE.UUCP should go to ...!fluke!user. Yep. Actually, since tc.fluke.com is not directly in the pathalias output, this will go to ...!fluke!tc.fluke.uucp!user, so locally you should also alias fluke = tc.fluke.com to cause it to be deliverd. > Mail to user@MIS.FLUKE.UUCP should go to ...!fluke!evtmis1!user. Sure does. >I'm playing with variations on this theme: > fluke .fluke /* host "fluke" > private {.tc, .mis} > .fluke = @{.tc, .mis}(LOCAL) > .mis evtmis1 > fluke @evtmis1(LOCAL), microsoft(DIRECT), ...<many other uucp connections> It is also possible to do it this way, but it requires a level of understanding so great that, as far as I can tell, only Peter Honeyman can make it work. It also requires global knowledge of other domains to avoid naming conflicts -- not even the "private" declaration is sufficient in general. -- -- Greg Noel, NCR Rancho Bernardo Greg@ncr-sd.UUCP or Greg@nosc.ARPA
