NAME
innxmit - send Usenet articles to a remote NNTP server
SYNOPSIS
innxmit [ -A alt_spool ] [ -a ] [ -c ] [ -d ] [ -l ] [ -M ] [ -r ] [ -s ] [ -t timeout ] [ -T timeout ] [ -p ] [ -S ] [ -P portnum ] host file
DESCRIPTION
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 /var/spool/news/out.going directory. 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 filename 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, /var/spool/news. 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.
OPTIONS
-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'' flag.
-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 times.
-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.
