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.  Mail routing information as produced by
Xpathalias is also displayed.  Since uuhosts needs the map information
Xfrom the USENET spool directory for mod.map extracted into a more
Xaccessible (and permanent) location, it can be used to do that, too.
X
XThis version of uuhosts, 1.59, works with the latest (September 1985)
Xmod.map postings.  It uses newsgroup mod.map instead of newsgroup
Xmod.map.uucp, which version 1.58 and all previous uuhosts used.  It
Xalso does map extraction quite differently from versions previous to
X1.52.  Rather than immediately extracting each article when it arrives,
Xa list is kept of the pathnames of incoming articles, and "uuhosts -unbatch"
Xis called nightly to do the extraction.  Because of both of these changes
X--->  It is necessary to completely reinstall uuhosts <--- using the new
Xinstallation instructions.
X
XOutput paging by means of more, pg, etc. has been added, due to popular
Xdemand.  A default pager must be set in the Makefile.  If the compile-time
Xparameters get much more complicated, I will probably pick up Larry Wall's
Xconfiguration package.
X
XPeculiar failures which I have not been able to reproduce here have
Xbeen reported from some systems running some ports of System V.  Please
Xlet me know of any problems, such as uuhosts not recognizing articles
Xin mod.map as valid, and mailing them to postmaster rather than
Xextracting them.
X
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 or other parameters which are incorrect for your
Xsystem.  Then do "make" to be sure everything compiles correctly.
XTo install the necessary shell script, C program, and manual entry,
Xas well as creating all necessary new directories, do "make install"
Xas root.
X
XOnce the program is installed, you will want to extract any existing
Xmod.map articles so uuhosts can display their information.  To do
Xthis, type "uuhosts -setup &".  Do not do it as root!  Do it as some
Xuser in group news.  It will take a while:  display speed has been
Xbought by slowness in extraction.  You should only ever need to do
Xthis once, because of the last installation steps:
X
XFinally, modify NEWS/sys by hand so that inews will batch incoming
Xmod.map articles, and also arrange for "uuhosts -unbatch" to
Xbe called nightly by cron.  See the MAINTENANCE section of the uuhosts
Xmanual entry for how to do this.  Do not call "uuhosts -unbatch" as root!
XHave it called as some user in group news.
X
X
XPathalias is not included here:  it was posted to net.sources recently.
XIf you have uupath, you may want to use it to look up UUCP routing
Xinformation 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 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.TH UUHOSTS 1L 85/09/17
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.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 (usually geographical) region.
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.PP
XOutput is broken into pages by the program named in the PAGER environment
Xvariable, or by a default pager set at compile time,
Xwhich is usually one of more, pg, or cat,
Xas appropriate for the host system.
X.SH MAINTENANCE
XNone of these options should be used by the super-user (root).
X.TP
Xuuhosts \-setup
XOnce "make\ install" has been done for the initial installation,
Xthis option may be used to extract any backlog of \fBUUCPMAPGROUP\fP articles.
XDo not run it as root!
XRun it as some user in group news.
X.TP
Xmaps:UUCPMAPGROUP:F:UUCPMAP/Batch
XThis line should go in \fBNEWS/sys\fP.
XIt causes \fIinews\fP(1L) to list the pathnames of incoming articles of
X\fBUUCPMAPGROUP\fP in the \fBBatch\fP file.
X.TP
Xuuhosts \-unbatch
XThis should be called nightly by \fIcron\fP(8) or whatever mechanism is
Xused to call the USENET \fIexpire\fP(8) command.
XIt extracts articles from \fBUUCPMAPGROUP\fP which have
Xcome in since the last time it was run.
XDo not run it as root!
XRun it as some user in group news.
X.TP
Xuuhosts \-x
XExtract an individual \fBUUCPMAPGROUP\fP article.
XOrdinarily called from \fIuuhosts\fP\ \-\fBunbatch\fP.
X.TP
Xuuhosts \-i
XRebuild the Index file (see below).
XOrdinarily called from \fIuuhosts\fP\ \-\fBunbatch\fP.
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 \fBUUCPMAPGROUP\fP
X(thanks to the UUCP mapping project).
XNotices of updates are mailed to \fBpostmaster\fP, 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.
X.SH SEE ALSO
Xvnews(1), readnews(1), mail(1), sendmail(8), look(1)

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, if either
X\fBPATHS\fP or \fBUUCPMAP/Index\fP is newer than \fBWHERE\fP.
XThe information in \fBWHERE\fP is displayed by \fIuuhosts\fP itself.
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.
