innxmit - send Usenet articles to a remote NNTP server
innxmit [ -a ] [ -c ] [ -d ] [ -H ] [ -l ] [ -P portnum ] [ -p ] [ -r ]
[ -s ] [ -T timeout ] [ -t timeout ] host file
Innxmit connects to the NNTP server at the specified host (validating
itself via passwd.nntp if possible) 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
<pathoutgoing in inn.conf> directory. It is normally written by speci-
fying the ‘‘Wnm’’ flags in the newsfeeds file. Each line in the batch-
file should be in one of the following formats:
The token field names the article to be sent. If the Message-ID field
is not specified, it will be obtained by scanning the article. The
token 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.
-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 exces-
sively large if many articles have been expired and there are
communication problems. To always rewrite the batchfile, use
the ‘‘-a’’ flag.
-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.
-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.
-H If the ‘‘-H’’ flag is given, then only headers are sent to host
for all articles except control messages. And Bytes: header is
also included even if it does not exist in the original article.
‘‘-H’’ flag is useful for diablo reader.
-l The ‘‘-l’’ flag is used to turn on logging of reasons the remote
gives for rejecting an article.
To specify a port number other than the default, use the ‘‘-P’’
-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.
-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.
-s Innxmit will attempt to negotiate a streaming mode extension of
the NNTP protocol with the server at connect time. If success-
ful 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.
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 trans-
ferred. If the ‘‘-T’’ flag is used, the time is checked just
before each article is started; it will not abort a transfer
that is in progress.
Innxmit normally blocks until the connection is made. To spec-
ify a timeout on how long to try to make the connection, use the
-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.
