INNXBATCH(8)INNXBATCH(8)NAMEinnxbatch - send xbatched Usenet articles to a remote NNTP
server
SYNOPSISinnxbatch [ -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 con-
nection, 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 file is removed after it has been successfully trans-
ferred.
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 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
## The next line should match <PATH_SHELLVARS in config.data>
. /var/news/etc/innshellvars
site="$1"; host="$2"; shift; shift
ctlinnd flush "$site" \
&& sleep 5 \
&& exec $NEWSBIN/innxbatch -v -D "$host" $*
