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 directory.

−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 syslog(3). |
Rnews cannot process articles that have embedded ’’\0’’ characters in them.
