NAME

       ninpaths - Report Usenet Path statistics (new inpaths)


SYNOPSIS

       ninpaths -p -d dumpfile

       ninpaths -r site -u dumpfile [-u dumpfile ...] -v level


DESCRIPTION

       This is an efficient and space-saving inpaths reporting program.  It
       works as follows:  you feed it the Path lines via an INN channel feed
       or some other similar method, and from time to time the program writes
       all its internal counters accumulated so far to a dump file.  Another
       instance of the program picks up all the dump files, adds them up and
       formats them into the report.  The purpose of the final report is to
       summarize the frequency of occurrence of sites in the Path headers of
       articles.

       Some central sites accumulate the Path data from many news servers run-
       ning this program or one like it, and then report statistics on the
       most frequently seen news servers in Usenet article Path lines.  The
       sendinpaths shell script can be run once a month to mail the accumu-
       lated statistics to such a site and remove the old dump files.

       You can get a working setup by doing the following:

       1.  Create a directory at pathlog/path (replacing pathlog here and in
           all steps that follow with the full path to your INN log direc-
           tory).

       2.  Set up a channel feed using an entry like:

               inpaths!:*:Tc,WP:ninpaths -p -d <pathlog>/path/inpaths.%d

           if your version of INN supports WP (2.0 and later all do).  Replace
           <pathlog> with the full path to your INN log directory.

       3.  Enter into your news user crontab something like:

               6 6 * * *   ctlinnd flush inpaths!

           (the actual time doesn’t matter).  This will force ninpaths to gen-
           erate a dump file once a day.

       4.  Once per month, run the sendinpaths script, which collects the
           dumps, makes a report, and then deletes the old dumps.  (You can
           generate a report without mailing it and without deleting it with
           "sendinpaths -n".)


OPTIONS

       -d dumpfile
           Save dumps in dumpfile.  Any %d in dumpfile will be replaced with
           the current system time when the dump is made.  This option should
           be used with -p.

       -p  Read Path lines from standard input.

       -r site
           Generate a report for site.  Generally site should be the value of
           pathhost from inn.conf.

       -u dumpfile
           Read data from dumpfile.  This option can be repeated to read data
           from multiple dump files.

       -v level
           Set the verbosity level of the report.  Valid values for level are
           0, 1, and 2, with 2 being the default.


NOTES

       If your INN doesn’t have the WP feed flag (1.5 does not, 1.6 does, 1.7
       I don’t know, 2.0 and later all do), use the following newsfeeds entry:

          inpaths!:*:Tc,WH:ginpaths

       where ginpaths is the following script:

           #!/bin/sh
           exec egrep ’^Path: ’ │ ninpaths -p -d <pathlog>/path/inpaths.%d

       replacing <pathlog> as above.

       This is a slightly modified version of Olaf Titz’s original ninpaths
       program, which is posted to alt.sources and kept on his WWW archive
       under <http://sites.inka.de/~bigred/sw/>.


HISTORY

       ninpaths was written by Olaf Titz <olaf@bigred.inka.de>.

       The idea and some implementation details for ninpaths come from the
       original inpaths program, but most of the code has been rewritten for
       clarity.  This program is in the public domain.
