Mod.sources:  Volume 2, Issue 15
Submitted by: harvard!ut-sally!jsq (John Quarterman)

Since the format of mod.map.uucp was changed recently (again), and
mod.map.news has been dropped, I've updated uuhosts to reflect that.
This posting of uuhosts works with the latest (June 1985) mod.map.uucp
postings.

: This is a shar archive.  Extract with sh, not csh.
echo x - README
sed -e 's/^X//' > README << '!RoNnIe!RaYgUn!'
XThis is the source directory for uuhosts, which may be used to display
XUUCP mail and USENET news information previously extracted from the
XUSENET newsgroup mod.map.uucp.  Mail routing information as produced by
Xpathalias is also displayed.  Since uuhosts needs the map information
Xfrom the USENET spool directory for mod.map.uucp extracted into a more
Xaccessible (and permanent) location, it can be used to do that, too.
X
XIf you don't have a UNIX group named news in /etc/group, you should
Xcreate one, as uuhosts depends on it.
X
XTo install uuhosts, first look at the beginning of the Makefile and
Xadjust any pathnames which are incorrect for your system.  Then do
X"make" to be sure everything compiles correctly.  To install the
Xnecessary shell script, C program, and manual entry, as well as
Xcreating all necessary new directories, do "make install" as root.
XFinally, modify NEWS/sys by hand so that inews will call "uuhosts -x"
Xwhen mod.map.uucp articles  arrive.  See uuhosts(1) for how to do this.
X
XOnce the program is installed, you will want to feed any existing
Xmod.map.uucp articles through "uuhosts -x" so they will be extracted and
Xuuhosts can later be used to display the information.  To do this, type
X"uuhosts -setup &".  Do not do it as root:  do it as some user in group
Xnews.  It will take a while:  display speed has been bought by slowness
Xin extraction.  You should only ever need to do this once, as any
Xmod.map.uucp articles that arrive later should be extracted
Xautomatically because of the NEWS/sys entry.
X
X
XThis posting of uuhosts works with the latest (June 1985)
Xmod.map.uucp postings.
X
XPathalias is not included here:  it was posted to net.sources a while
Xback.  If you have uupath, you may want to use it to look up UUCP
Xrouting information instead of the method uuhosts uses by default.
XJust look for uupath in uuhosts.sh and it's obvious what to change.
X
X
XFor the mod.map.uucp extraction (and *only* that extraction), uuhosts
Xdepends on a small setuid program called mapsh (included here) which
Xuses chroot(2), which is in (at least) 4BSD, System N, and Version 7.
XThe purpose of mapsh is to limit the commands which may be executed
Xwhen found in a map article.  If you trust everyone who can post to
XUSENET from any machine in the world, you can probably replace mapsh
Xwith "cd $MAPS; sh".  Or you can use unmvax!lee's article parser in C,
Xif you like.
X
X
XHere is an example of the most common use of uuhosts, which is to
Xdisplay information about a particular host:
X
X% uuhosts seismo
XUUCP mail path for seismo:
Xseismo    seismo!%s
XUUCP mail path for seismo annotated by location:
Xseismo(usa.va)    seismo(usa.va)!%s

X.TH UUHOSTS 1L 85/06/07
X.SH NAME
Xuuhosts \- UUCP mail and USENET news information.
X.SH SYNOPSIS
X.B
Xuuhosts
Xhostname ...
X.br
X.B
Xuuhosts
X-r [ region ]
X.br
X.B
Xuuhosts
X-x
X.br

X.SH DESCRIPTION
XThe \fIuuhosts\fP command is used to look up information about
Xthe configurations of the UUCP mail network and the USENET news network.
X.TP
Xuuhosts \fIhostname\fP ...
Xfor information about a particular UUCP or USENET host or hosts.
XThe UUCP mail path is given first, followed by the map information.
XThe USENET map is carried as notations in entries in the UUCP map,
Xin the lines starting with ``#USENET''.
XAny hosts with names for which the argument is a prefix are shown, e.g.:
X.TP
Xuuhosts ut
Xgets information about all hosts whose names start with ``ut''.
X.TP
Xuuhosts \-r \fIregion\fP
Xfor information about hosts in a region (usually geographical) networks.
X.TP
Xuuhosts \-r README
Xgets an introduction to the map.
X.TP
Xuuhosts \-r Local
Xgets map information known only locally.
X.TP
Xuuhosts \-r
Xfor a list of known regions.
X.TP
Xuuhosts
Xwith no arguments gets a short usage message.
X.SH MAINTENANCE
XIn addition to the options mentioned above, there is
X.TP
Xuuhosts \-x
XExtract pieces of the map from a mod.map.uucp article.
X.PP
XThis should be called automatically by a line in \fBNEWS/sys\fP like
X.IP
Xmaps:mod.map.news,mod.map.uucp:B:BIN/uuhosts\ \-x
X.TP
Xuuhosts \-i
Xrebuilds all the Index files (see below).
X.LP
XThere are more details in the uuhosts shell script itself.
X.SH FILES
X.TP
XPATHS
XUUCP mail path database as produced by \fIpathalias\fP and used by \fInmail\fP
X(which is called automatically from \fIsendmail\fP on \fIut\-sally\fP)
XIt is searched by \fIlook\fP(1), if present, else \fIgrep\fP(1).
XThe file WHERE is similarly searched, if present:
Xsee \fIuuwhere\fP(1).
X.TP
XUUCPMAP
XUUCP and USENET map information taken from newsgroup \fBmod.map.uucp\fP
X(thanks to the UUCP mapping project).
XNotices of updates are mailed to postmaster, which should be an alias
Xredistributing to the local mail and UUCP administrators.
X.TP
XUUCPMAP/Index
XThis index is used to decrease search time on the map about an order
Xof magnitude.
XThe search is done by either \fIlook\fP(1) or \fIgrep\fP(1), as above.
XThe index is updated each time a mod.map.uucparticle arrives,
Xand may be manually forced by ``uuhosts\ \-i''.
X.TP
XNEWS/sys
XContains arrangements to call "uuhosts\ \-x".
X.SH SEE ALSO
Xvnews(1), readnews(1), mail(1), sendmail(8), look(1)
X.SH BUGS
XHaving uuhosts\ \-x create a complete new Index for each incoming article
Xis clumsy, takes a long time, and eats CPU.
XOn the other hand, articles don't come in but once or two at a time.
XIf anybody has a clever method of handling this (given that ordinary
Xusers may read but not write on the map directories), let me know.
XIt is possible to disable indexing for a given uuhosts\ \-x call
Xby doing ``DONTINDEX=1;\ export\ DONTINDEX'' (or ``setenv\ DONTINDEX\ 1''
Xin csh) before the uuhosts call.

X.TH UUW\HERE 1L 85/02/02
X.SH NAME
Xuuwhere \- annotate UUCP mail routes by host location
X.SH SYNOPSIS
X.B
XLIB/uuwhere
X[ -c ]
X[ infile ]
X.SH DESCRIPTION
XThe \fIuuwhere\fP command is used take a list of UUCP routes,
Xsuch as produced by \fIpathalias\fP, and make a similar list,
Xannotated by the geographical location of each host as found
Xin the UUCP map posted to USENET newsgroup mod.map.uucp.
XIt is ordinarily called with no arguments by \fIuuhosts\fP(1L),
Xand will update \fBWHERE\fP, taking routes from \fBPATHS\fP and locations
Xfrom \fBUUCPMAP/Index\fP (and possibly \fBNEWSMAP/Index\fP), if either
X\fBPATHS\fP or \fBUUCPMAP/Index\fP is newer than \fBWHERE\fP.
X.PP
XInput file names may be specified as arguments.
XThis also causes output to go to standard output instead of directly to
XInput file name \fI-\fP is taken to be standard input.
X\fBWHERE\fP.
X.TP
X\-\fBc
X\fIUuwhere\fP uses a \fIdbm\fP(3) database to store the location information
Xfrom \fBUUCPMAP/Index\fP before creating output.
XThis option causes \fIuuwhere\fP to recreate the database regardless
Xof the state of any input files.
X.SH FILES
X.TP
XWHERE
XThe place where the output of \fIuuwhere\fP is usually kept for use
Xby \fIuuhosts\fP.
X.TP
XPATHS
XThe default route list used as input by \fIuuwhere\fP.
XProduced by \fIuuhosts\fP.
X.TP
XUUCPMAP/Index
XThe source of the location information used by \fIuuwhere\fP.
XProduced by \fIpathalias\fP.
X.SH SEE ALSO
