innxbatch(8)


NAME

   innxbatch - send xbatched Usenet articles to a remote NNTP server

SYNOPSIS

   innxbatch [ -D ] [ -t timeout ] [ -T timeout ] [ -v ] host file ...

DESCRIPTION

   Innxbatch  connects  to the NNTP server at the specified host and sends
   it the specified xbatch files, using the XBATCH extension to  the  NNTP
   protocol.  It  is  normally invoked by a script run out of cron(8) that
   uses shlock(1) to lock the host name, followed by a ctlinnd(8)  command
   to flush the batchfile.

   Innxbatch  normally  blocks until the connection is made.  To specify a
   timeout on how long to try to make the connection, use the ``-t'' flag.
   To specify the total amount of time that should be allowed for  article
   transfers, use the ``-T'' flag.
   The  default  is to wait until an I/O error occurs, or all the articles
   have been transferred. If the ``-T'' flag is used, the time is  checked
   just before an article is started; it will not abort a transfer that is
   in progress. Both values are measured in seconds.

   Each fileis removed after it has been successfully transferred.

   If a communication error such as a write(2) failure, or  an  unexpected
   reply  from  the  remote server occurs, innxbatch will stop sending and
   leave all remaining files untouched for later retry.

   Upon exit, innxbatch reports transfer  and  CPU  usage  statistics  via
   syslog(3).   If  the  ``-v'' flag is used, they will also be printed on
   the standard output.

   Use the ``-D'' flag to print debugging information on  standard  error.
   This will show the protocol transactions between innxbatch and the NNTP
   server on the remote host.

   A sample newsfeeds(5) entry to produce appropriate xbatch files (thanks
   to Karsten Leipold <poldi@dfn.de>):

     nase\
       :*\
       :Tc,Wnb\
       :/usr/lib/news/bin/batcher \
          -p "(/bin/gzip > /var/spool/news/out.going/nase.\$\$)" \
          nase.do.main

   A sample script to invoke innxbatch(8) is:

     #!/bin/sh
     ##  SH script to send xbatches for a site, wrapped around innxbatch
     ##  Invocation:
     ##     sendxbatches.sh <sitename> <hostname> <xbatch file name> ...

     if [ $# -le 3 ]
     then
        echo "usage: $0 <sitename> <hostname> <xbatch file name>"
        exit 1
     fi

     ##  =()<  . @<_PATH_SHELLVARS>@>()=
     . /usr/lib/news/innshellvars

     site="$1"; host="$2"; shift; shift

     ctlinnd flush "$site" \
     && sleep 5 \
     && exec $NEWSBIN/innxbatch -v -D "$host" $*

HISTORY

   Written   by   Stefan  Petri  <petri@ibr.cs.tu-bs.de>,  modelled  after
   innxmit(8) and the XBATCH patch for the nntp reference implementation.
