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 file is 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 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" \e
&& sleep 5 \e
&& exec $NEWSBIN/innxbatch -v -D "$host" $*
