innxbatch - send xbatched Usenet articles to a remote NNTP server SYNOPSIS
innxbatch [ -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 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.

NNTPSEND(8) System Manager's Manual NNTPSEND(8) NAME
nntpsend - send Usenet articles to remote site SYNOPSIS
nntpsend [ -a ] [ -c ] [ -D ] [ -d ] [ -l ] [ -N ] [ -n ] [ -P portnum ] [ -p ] [ -r ] [ -S ] [ -s size ] [ -T timelimit ] [ -t timeout ] [ -w delay ] [ sitename fqdn ] ... DESCRIPTION
Nntpsend is a front-end that invokes innxmit(1) to send Usenet articles to a remote NNTP site. The sites to be fed may be specified by giving sitename fqdn pairs on the command line. If no such pairs are given, nntpsend defaults to the information given in the nntpsend.ctl config file. The sitename should be the name of the site as specified in the newsfeeds(5) file. The fqdn should be the hostname or IP address of the remote site. An innxmit is launched for sites with queued news. All innxmit processes are spawned in the background and the script waits for them all to finish before returning. Output is sent to the file <pathlog in inn.conf>/nntpsend.log. In order to keep from overwhelming the local system, nntpsend waits five seconds before spawning each child. Nntpsend expects that the batchfile for a site is named <pathoutgoing in inn.conf>/sitename. To prevent batchfile corruption, shlock(1) is used to ``lock'' these files. When sitename fqdn pairs are given on the command line, any flags given on the command completely describe how innxmit and shrinkfile oper- ate. When no such pairs are given on the command line, then the information found in nntpsend.ctl becomes the default flags for that site. Any flags given on the command line override the default flags for the site. OPTIONS
-d -D The ``-d'' flag causes nntpsend to send output to stdout rather than the log file <pathlog in inn.conf>/nntpsend.log. The ``-D'' flag does the same and it passes ``-d'' to all innxmit invocations, which in turn causes innxmit to go into debug mode. -n If the ``-n'' flag is used, then nntpsend does not use shlock(1) and does not lock batch files. -s size If the ``-s'' flag is used, then shrinkfile(1) will be invoked to perform a head truncation on the batchfile and the flag will be passed to it. -w delay If the ``-w'' flag is used, then nntpsend waits for delay seconds after flushing the site before launching innxmit. -a -c -l -N -P -p -r -S -T -t The ``-a'', ``-c'', ``-l'', ``-P'', ``-p'', ``-r'', ``-S'', ``-T'' and ``-t'' flags are passed on to the child innxmit program. The ``-N'' flag is passed as ``-s'' flag to the child innxmit program. See innxmit(8) for more details. Note that if the ``-p'' flag is used then no connection is made and no articles are fed to the remote site. It is useful to have cron(8) invoke nntpsend with this flag in case a site cannot be reached for an extended period of time. EXAMPLES
