innxmit - send Usenet articles to a remote NNTP server

     innxmit [ -A alt_spool ] [ -a ] [ -c ] [ -d ] [ -l ] [ -M ] [ -r ] [ -s ]
     [ -t timeout ] [ -T timeout ] [ -p ] [ -S ] [ -P portnum ] host file

     Innxmit connects to the NNTP server at the specified host  and  sends  it
     the  articles  specified  in  the  batchfile  named file.  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.

     If the file is not an absolute pathname, it  is  taken  relative  to  the
     <config$_PATH_BATCHDIR> directory (typically /var/news/spool/out.going .)
     It  is  normally  written  by  specifying  the  ``Wnm''  flags   in   the
     newsfeeds(5)   file.   Each  line in the batchfile should be in one of the
     following formats:

          filename Message-ID

     The filename field names the article  to  be  sent.   If  it  is  not  an
     absolute  pathname  it  is  taken  relative  to the news spool directory,
     <config$_PATH_SPOOL>  (typically   /var/news/spool/articles.)    If   the
     Message-ID  field  is  not specified, it will be obtained by scanning the
     article.  The filename and Message-Id fields are separated by a space.

     If a communication error such as a write(2) failure occurs, innxmit  will
     stop sending and rewrite the batchfile to contain the current article and
     any other unsent articles.


     -t   Innxmit normally blocks until the connection is made.  To specify  a
          timeout  on  how  long to try to make the connection, use the ``-t''

     -T   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.

     -P   To specify a port number other than the default, use the -P flag.

     -r   If the remote server sends an unexpected reply  code,  innxmit  will
          requeue the article and proceed.  Use the ``-r'' flag if the article
          should not be requeued.

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

     -a   If all articles were sent  successfully,  innxmit  will  remove  the
          batchfile,  otherwise  it  will  rewrite  it  to contain the list of
          unsent articles.  If no articles were sent or rejected, the file  is
          left untouched.  This can cause the batchfile  to  grow  excessively
          large if many articles have been expired and there are communication
          problems.  To always rewrite the batchfile, use the ``-a'' flag.

     -p   If the ``-p'' flag is given, then no  connection  is  made  and  the
          batchfile  is  purged  of entries that refer to files that no longer
          exist.  This implies the ``-a'' flag.

     -S   If the ``-S'' flag is given, then innxmit will offer articles to the
          specified host using the ``xreplic'' protocol extension described in
          innd(8) .  The ``-S'' flag implies ``-s'',  since  streaming  is  not
          supported in the xreplic protocol.  To use this flag, the input file
          must contain the history data (commas are transliterated  to  spaces
          by  the  server).  In order for this flag to be used, the input must
          contain the necessary history entries.   This  is  usually  done  by
          setting up a ``WnR'' entry in the newsfeeds file.

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

     -l   The ``-l'' flag is used to turn off logging of  reasons  the  remote
          gives for rejecting an article.

     -M   If the ``-M'' flag is used  then  innxmit  will  scan  an  article's
          headers  before  sending  it.   If  the article appears to be a MIME
          article that is not in seven-bit format, the article will be sent in
          ``quoted-printable'' form.

     -A   The ``-A'' flag may be used to specify an alternate spool  directory
          to  use  if the article is not found; this would normally be an NFS-
          mounted spool directory of a master server  with  longer  expiration

     -s   Innxmit will attempt to negotiate a streaming mode extension of  the
          NNTP  protocol  with  the  server at connect time.  If successful it
          will use a slightly different protocol that enhances throughput.  If
          the server does not recognize the streaming mode negotiation innxmit
          will revert to normal NNTP transfer mode.  Use the  ``-s''  flag  to
          disable the attempt to negotiate the streaming mode extension.

     -c   In streaming mode a check of each message ID is still made to  avoid
          sending  articles  already  on the server.  The ``-c'' flag will, if
          streaming mode is supported,  result  in  sending  articles  without
          checking.   This  results  in slightly greater throughput and may be
          appropriate when it is known that the site could  not  already  have
          the articles such as in the case of a "leaf" site.
