rnews - receive news from a UUCP connection
rnews [ -h host ] [ -N ] [ -P port ] [ -r remote ] [ -S remote ] [ -U ] [
-v ] [ input ]
Rnews reads messages typically queued by a UUCP newsfeed and sends them to
the InterNetNews server (either ``localhost'', or the value defined by the
variable <nnrpdposthost in inn.conf>.
The message is read from the specified input file, or standard input if no
input is named.
When sent over UUCP, Usenet articles are typically joined in a single batch
to reduce the UUCP overhead. Batches can also be compressed, to reduce the
communication time. If a message does not start with a number sign (``#'')
and an exclamation point, then the entire input is taken as a single news
article. If it does start with with those two characters, then the first
line is read and interpreted as a batch command.
If the command is ``#! rnews nnn'' where nnn is a number, then the next nnn
bytes (starting with the next line) are read as a news article.
If the command is ``#! cunbatch'' then the rest of input is fed to the
compress(1) program with the ``-d'' flag to uncompress it, and the output
of this pipe is read as rnews's input. This is for historical
compatibility - there is no program named cunbatch. A compressed batch
will start with a ``#! cunbatch'' line, then contain a series of articles
separated by ``#! rnews nnn'' lines. If <DO_RNEWSPROGS in
include/config.h> is defined and the command is any other word, then rnews
will try to execute a program with that name in the directory
<pathbin in inn.conf>/bin/rnews.libexec.
The batch will be fed into the program's standard input, and the standard
output will be read back as input into rnews. If <DO_RNEWS_SAVE_BAD in
include/config.h> is defined and rnews detects any problems with an article
such as a missing header, or an unintelligible reply from the server, it
will save a copy of the article in the <pathincoming in inn.conf>/bad
-h If the ``-h'' flag is given, then rnews will log the Message-ID and
host via syslog(3) for each article offered to the server. Logging
will only be done if the value is not an empty string. If ``-h'' is
not set, the environment variable <_ENV_UUCPHOST in include/paths.h>
(typically $UU_MACHINE) will be examined for a similar string.
-N Normally, if unpacking the input fails it is re-spooled to
<pathincoming in inn.conf> for another attempt later. If the ``-N''
flag is used then no such re-spooling is done and rnews exits with
status value ``9'' to indicate this.
-P If the ``-P'' flag is used, then the articles will be sent to the
specified port on the remote host.
-r If the ``-r'' flag is used, then the articles will be sent to the
named remote host instead of the default host.
-S ``-S'' flag is equivalent to ``-r'' flag.
-U If the server is not available, the message is spooled into a new file
created in the <pathincoming in inn.conf> directory. The ``-U'' flag
may be used to send all spooled messages to the server once it becomes
available again, and can be invoked regularly by cron(8).
-v If the ``-v'' flag is used, it will print a notice of all errors on
the standard error, naming the input file (if known) and printing the
first few characters of the input. Errors are always logged through
Rnews cannot process articles that have embedded ``\0'' characters in them.
