NAME

tinews.pl - Post and sign an article via NNTP

SYNOPSIS

tinews.pl [OPTIONS] < input

DESCRIPTION

tinews.pl reads an article on STDIN, signs it via pgp(1) or gpg(1) and posts it to a news server.
The article shall not contain any raw 8-bit data or it needs to already have the relevant MIME-headers as tinews.pl will not add any MIME-headers nor encode its input.
If the article contains To:, Cc: or Bcc: headers and mail-actions are configured it will automatically add a Posted-And-Mailed: yes header to the article and send out the mail-copies.
If a Cancel-Lock secret file is defined it will automatically add a Cancel-Lock: (and Cancel-Key: if required) header.
The input should have unix line endings (<LF>, ’\n’).

OPTIONS

-a Approved | --approved Approved Set the article header field Approved: to the given value.
-c Control | --control Control Set the article header field Control: to the given value.

-e Expires | --expires Expires Set the article header field Expires: to the given value.
-f From | --from From Set the article header field From: to the given value.
-i header | --ignore-headers header Comma separated list of headers that will be ignored during signing. Usually the following headers will be signed if present:
From, Newsgroups, Subject, Control, Supersedes, Followup-To, Date, Injection-Date, Sender, Approved, Message-ID, Reply-To, Cancel-Key, Also-Control and Distribution.
Some of them may be altered on the Server (i.e. Cancel-Key) which would invalid the signature, this option can be used the exclude such headers if required.
-n Newsgroups | --newsgroups Newsgroups Set the article header field Newsgroups: to the given value.

-I | --no-injection-date Do not add Injection-Date: header.
-L | --no-canlock Do not add Cancel-Lock: / Cancel-Key: headers.
--canlock-algorithm Algorithm Digest algorithm used for Cancel-Lock: / Cancel-Key: headers. Supported algorithms are sha1, sha256 and sha512. Default is sha1.
-R | --no-control Restricted mode, disallow control-messages.
-S | --no-signature Do not append $HOME/.signature.
-X | --no-sign Do not sign the article.
-Y | --force-auth Force authentication on connect even if not required by the server.

-h | --headers These options are accepted for compatibility reasons but ignored.
-O | --no-organization These options are accepted for compatibility reasons but ignored.

EXIT STATUS

The following exit values are returned:
0 Successful completion.
!=0 An error occurred.

ENVIRONMENT

$NEWSHOST Set to override the NNTP server configured in the source or config-file. It has lower priority than $NNTPSERVER and should be avoided.
$NNTPSERVER Set to override the NNTP server configured in the source or config-file. This has higher priority than $NEWSHOST.
$NNTPPORT The NNTP TCP-port to post news to. This variable only needs to be set if the TCP-port is not 119 (the default). The ’-p’ command-line option overrides $NNTPPORT.
$PGPPASS Set to override the passphrase configured in the source (used for pgp(1)-2.6.3).
$PGPPASSFILE Passphrase file used for pgp(1) or gpg(1).
$SIGNER Set to override the user-id for signing configured in the source. If you neither set $SIGNER nor configure it in the source the contents of the From:-field will be used.
$REPLYTO Set the article header field Reply-To: to the return address specified by the variable if there isn’t already a Reply-To: header in the article. The ’-r’ command-line option overrides $REPLYTO.
$ORGANIZATION Set the article header field Organization: to the contents of the variable if there isn’t already an Organization: header in the article. The ’-o’ command-line option overrides $ORGANIZATION.
$DISTRIBUTION Set the article header field Distribution: to the contents of the variable if there isn’t already a Distribution: header in the article. The ’-d’ command-line option overrides $DISTRIBUTION.

FILES

pgptmp.txt Temporary file used to store the reformatted article.
pgptmp.txt.asc Temporary file used to store the reformatted and signed article.
$PGPPASSFILE The passphrase file to be used for pgp(1) or gpg(1).
$HOME/.signature Signature file which will be automatically included.
$HOME/.cancelsecret The passphrase file to be used for Cancel-Locks. This feature is turned off by default.
$HOME/.newsauth nntpserver password [user] pairs for NNTP servers that require authorization. Any line that starts with # is a comment. Blank lines are ignored. This file should be readable only for the user as it contains the user’s unencrypted password for reading news. First match counts. If no matching entry is found $HOME/.nntpauth is checked.
$HOME/.nntpauth nntpserver user password pairs for NNTP servers that require authorization. First match counts. Lines starting with # are skipped and blank lines are ignored. This file should be readable only for the user as it contains the user’s unencrypted password for reading news. $HOME/.newsauth is checked first.
$XDG_CONFIG_HOME/tinewsrc $HOME/.config/tinewsrc $HOME/.tinewsrc option=value configuration pairs. Lines that start with # are ignored. If the file contains unencrypted passwords (e.g. NNTPPass or PGPPass), it should be readable for the user only.

SECURITY

If you’ve configured or entered a password, even if the variable that contained that password has been erased, it may be possible for someone to find that password, in plaintext, in a core dump. In short, if serious security is an issue, don’t use this script.

NOTES

tinews.pl is designed to be used with pgp(1)-2.6.3, pgp(1)-5, pgp(1)-6, gpg(1) and gpg2(1).
tinews.pl requires the following standard modules to be installed: Getopt::Long(3pm), Net::NNTP(3pm), <Time::Local(3pm)> and Term::Readline(3pm).
If the Cancel-Lock feature (RFC 8315) is enabled the following additional modules must be installed: MIME::Base64(3pm), Digest::SHA(3pm) or Digest::SHA1(3pm) and Digest::HMAC_SHA1(3pm). sha256 and sha512 as algorithms for canlock-algorithm are only available with Digest::SHA(3pm).
gpg2(1) users may need to set $GPG_TTY, i.e.

 GPG_TTY=$(tty)
 export GPG_TTY
before using tinews.pl. See <https://www.gnupg.org/> for details.
tinews.pl does not do any MIME encoding, its input should be already properly encoded and have all relevant headers set.
