				.TH NNTPSEND 8				.SH NAME				nntpsend \- send Usenet articles to remote site				.SH SYNOPSIS				.B nntpsend				[				.B \-d				]				[				.B \-p				]				[				.B \-r				]				[				.B \-S				]				[				.BI \-s " size"				]				[				.BI \-t " timeout"				]				[				.BI \-T " timelimit"				]				[				.I sitename				.I fqdn				] ...				.SH DESCRIPTION				.I Nntpsend				is a front-end that invokes				.IR innxmit (1)				to send Usenet articles to a remote NNTP site.				.PP				The sites to be fed may be specified by giving				.I sitename				.I fqdn				pairs on the command line.				If no such pairs are given,				.I nntpsend				defaults to the information given in the				.IR nntpsend.ctl (5)				config file.				.PP				The				.I sitename				should be the name of the site as specified in the				.IR newsfeeds (5) 				file.				The 				.I fqdn 				should be the hostname or IP address of the remote site.				.PP				An				.I innxmit				is launched for sites with queued news.				All				.I innxmit				processes are spawned in the background and the script waits for				them all to finish before returning.				Output is sent to the file				.\" =()()=				.IR /var/spool/news/data/nntpsend.log .				In order to keep from overwhelming the local system, 				.I nntpsend				waits five seconds before spawned each child.				The flag ``\-a'' is always given as a flag to				.IR innxmit .				.PP				.I Nntpsend				expects that the batchfile for a site is named				.\" =()()=				.IR /var/spool/news/out.going/sitename .				To prevent batchfile corruption,				.IR shlock (1)				is used to ``lock'' these files.				.PP				The ``\-p'', ``\-r'', ``\-S'', ``-t'', and ``-T'' flags are passed on to				the child				.I innxmit				program.				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				.IR cron (8)				invoke				.I nntpsend				with this flag in case a site cannot be reached for an extended period of time.				.PP				If the ``\-s'' flag is used, then				.IR shrinkfile (1)				will be invoked to perform a tail truncation on the batchfile and the flag				will be passed to it.				.PP				When				.I sitename				.I fqdn				pairs are given on the command line, 				any flags given on the command completely describe how				.I innxmit				and				.I shrinkfile				operate.				When no such pairs are given on the command line, then				the information found in				.I nntpsend.ctl				becomes the default flags for that site.				Any flags given on the command line override the default flags				for the site.				.PP				For example, with the following control file:				.RS				.nf				nsavax:erehwon.nsavax.gov::-S -t60				group70:group70.org::				walldrug:walldrug.com:1m:-T1800 -t300				.fi				.RE				.PP				The command:				.RS				nntpsend				.RE				will result in the following:				.RS				.nf				.ta \w'sitename   'u +\w'truncation   'u				Sitename	Truncation	Innxmit flags				nsavax	(none)	\-a \-S \-t60				group70	(none)	\-a \-t180				walldrug	1m	\-a \-T1800 \-t300				.fi				.RE				.PP				The command:				.RS				nntpsend \-d \-T1200				.RE				will result in the following:				.RS				.nf				.ta \w'sitename   'u +\w'truncation   'u				Sitename	Truncation	Innxmit flags				nsavax	(none)	\-a \-d \-S \-T1200 \-t60				group70	(none)	\-a \-d \-T1200 \-t180				walldrug	1m	\-a \-d \-T1200 \-t300				.fi				.RE				.PP				The command:				.RS				nntpsend \-s 5m \-T1200 nsavax erehwon.nsavax.gov group70 group70.org				.RE				will result in the following:				.RS				.nf				.ta \w'sitename   'u +\w'truncation   'u				Sitename	Truncation	Innxmit flags				nsavax	5m	\-a \-T1200 \-t180				group70	5m	\-a \-T1200 \-t180				.fi				.RE				.PP				Remember that ``\-a'' is always given, and ``\-t'' defaults to 180.				.SH HISTORY				Written by Landon Curt Noll 				and Rich $alz  for InterNetNews.				.de R$				This is revision \\$3, dated \\$4.				..				.R$ $Id: nntpsend.8,v 1.3 1992/08/14 20:37:08 rsalz Exp $				.SH "SEE ALSO"				innxmit(1), 				newsfeeds(5),				nntpsend.ctl(5),				shrinkfile(1).
