Submitted by: Ronald S. Karr <tron@nsc.NSC.COM>
Mod.sources: Volume 7, Issue 87
Archive-name: paths.mk
The following is a shell archive containing a Makefile and sample data
files for creating a paths file suitable for smail and other UUCP-domain
routing programs.
Also included is the patch to smail that I posted to net.sources.
The patch allows the specification of a site to send any mail
that you can't route.
This package assumes that you have pathalias, makedb (part of the pathalias
distribution) and the compress utilities running on your system. If you
are not using makedb or the compress utilities, you will need to edit
the Makefile to remove references to these programs.
If you are running uuhosts to unbatch USENET map files, you will need to
modify it to use the Makefile given here to create paths file. This
makefile will run uuwhere, to create the paths file annotated by location.
If you don't use this or have the uuwhere program somewhere other than
where we have it on our system, you will need to modify the Makefile.

XX
XX The files in this distribution comprise a set of programs
XX and sample data files for the generation of a paths file
XX for use with smail or other mailers that can use the data
XX generated by pathalias.
XX
XX To configure the system for your site, write some local
XX connections maps in some files in this directory, write
XX a dead, forces and local.map file, using the samples as
XX guidelines, and edit the Makefile to reflect your current
XX domain configuration.
XX
XXThe files in this directory:
XX
XXDocumentation
XX
XX README
XX This file.
XX
XX
XXFiles used for generating local connection paths
XX
XX domain.com.samp
XX The connection map for the top level of the DOMAIN.COM domain.
XX A path file is generated for this independently of the
XX the path file generation for external references. Then,
XX the paths in this file are merged into the normal paths
XX file, overriding any of its paths.
XX
XX sub.domain.com.samp
XX The connection map for the local subdomain of the domain
XX DOMAIN.COM. This is used concurrently with the domain.com
XX file for path generation.
XX
XX local.paths
XX The paths computed from pathalias operating upon domain.com
XX and sub.domain.com.
XX
XX
XXFiles used for generating external connection paths
XX
XX oursite.samp
XX The external connection map for this host. This should
XX only contain information for machines talking to other
XX machines outside of the DOMAIN.COM domain and should not
XX contain information on connections within the DOMAIN.COM
XX domain.
XX
XX local.map.samp
XX General connection map that contains information which
XX we know about, but which is not broadcast. This can also
XX be used to give lower values to connections, so that
XX they will be used in preference to other connections.
XX This file is used concurrently with external maps path
XX generation.
XX
XX dead.samp
XX A list of links we consider to be dead, thus overriding
XX whatever anybody else says.
XX
XX extern.paths.samp
XX The paths computed from the USENET maps and the above
XX files.
XX
XX
XXOther files
XX forces.samp
XX A file of explicit paths to override any paths computed
XX by Pathalias.
XX Makefile.FORM
XX A makefile for generating the complete path database
XX in /usr/lib/uucp/paths{,.dir,.pag}. Also generates
XX the intermediate file local.paths and stripdom.
XX stripdom.c
XX Source for a program that filters pathalias output to
XX generate multiple lines for each hostname having the
XX form:
XX
XX host.xx.domain.com
XX
XX to make these names equivalent:
XX
XX host.xx
XX host.xx.domain
XX host.xx.domain.com
XX
XX Alternate domains to simplify can be specified in the
XX Makefile.
XX pathmerge.c
XX Source for a program to take multiple sorted path files
XX as input files and produce on the standard output one path
XX to all machines listed, with preference given to paths
XX in the first files referenced in the argument list.
XX
XX At present, this program does not work correctly when
XX given more than two input files. However, pathmerge
XX can be cascaded as shown in Makefile.

XX * LOCAL DOMAIN QUALIFICATION PROGRAM
XX *
XX * @(#)stripdom.c 1.2 9/19/86
XX * @(#) Ronald S. Karr <tron@mesa.nsc.com>
XX * @(#) National Semiconductor, Sunnyvale
XX *
XX * This program accepts on the standard input a pathalias path
XX * database and an argument list containing fully qualified
XX * domains that the current machine is in. Then on the standard
XX * output this list is reproduced with any hosts in the given
XX * fully-qualified domains reproduced on separate lines in less
XX * qualified domains. The output is ordered such that a sorted
XX * file on input will be sorted on output as well.
XX *
XX * USAGE:
XX * pathalias ... | stripdomain full-domain full-domain ... | ...
XX *
XX * NOTE:
XX * ordering of full-domains in the argument list is not important
XX * as the arguments are sorted by size before processing starts.
XX * Also: Domains should be given with the initial dot.
XX *
XX * EXAMPLE:
XX * Given the command "stripdomain .nsc.com .sc.nsc.com" the following
XX * input:
XX * a.sc.nsc.com m!a!%s
XX * b.b16.sc.nsc.com n!b!%s
XX * c.nsc.com o!c!%s
XX * d.ta.nsc.com p!d!%s
XX * e q!e!%s
XX * f.com r!f!%s
XX *
XX * produces the following output:
XX * a.sc m!a!%s
XX * a.sc.nsc m!a!%s
XX * a.sc.nsc.com m!a!%s
XX * b.b16.sc n!b!%s
XX * b.b16.sc.nsc n!b!%s
XX * b.b16.sc.nsc.com n!b!%s
XX * c.nsc o!c!%s
XX * c.nsc.com o!c!%s
XX * d.ta.nsc p!d!%s
XX * d.ta.nsc.com p!d!%s
