Free stdin c software for linux

Grinch is a small script written in Perl which can be used to check whether a given address is an open mail relay host. It can operate as a daemon and speaks the tcp_map protocol implemented in Postfix in that case.

Its also possible to use it in arbitrary shell script environments where the hostname is read from stdin and the error code is written to stdout.

The goal is to check "on the fly" whether a host accepts mail to a given destination it actually may not relay for. If it does, Grinch waits for the sent mail to return to you for a configurable period and meanwhile returns a soft error (450) for that host.

If the mail returns, the suspected host was verified as an open open relay and will be rejected until its cache entry times out.

iodine is a piece of software that lets you tunnel IPv4 data through a DNS server. This can be useful in situations where Internet access is firewalled, but DNS queries are allowed.
iodine needs a TUN/TAP device to operate. The bandwidth is asymmetrical with limited upstream and up to 1 Mbit/s downstream.
Enhancements:
- Multiuser support was added for up to 8 users simultaneously.
- Authentication was added, and a password is entered as an argument or on stdin.
- A manpage was added. "make" targets were added for "install" and "uninstall".
- The DNS code was cleaned up.
- More test cases were added.
- The directory structure was changed.

GINS a.k.a. Gtk INterface for Script is a way to add GTK interfaces to scrpit languages that doesnt have any GTK bindigs, like BASH scripts. GINS load a GLADE xml file, using libglade. Then run the script, linking to his stdin & stdout.
Now script can communicate to GINS simply writting to stdin and reading from stdinput.
GINS pass to script every events that occours to gtk widgets, and script can react.
Enhancements:
- BradC: This version of GINS adds the ability to get boolean and double and the ability to set ints. So we can both get and set; int, str, double and boolean.

Crystality Plugin consists of XMMS plugin and stdin/stdout plugin. It was written for realtime remastering of sound from mp3 files.
You will need a reasonably good stereo and a good ear to notice quality
improvement, otherwise this is not for you.

This plugin tries to patch mp3 format flaws, not a poor audio hardware! Yes, you should be able to hear well enough (sorry) - for some of my friends plugin is a cool thing, while the others does not hear nothing but echo and stereo expander (well, you will hear every effect if you set it to the maximum, but it will not sound nice).

Crystality was written for 16bit 44.1kHz stereo sound and may give strange results
with other sound formats.

Damian Hodgkiss sent me a quick port for Winamp 2.x. I have not tried it yet, but you can get it (cr-quick-winamp-port.zip).

This plugin does mainly four things (and some minor tricks):

1. Adds some sounds in very high frequency range. Most of the mp3s in The Net are flawed with a 16(15?) kHz cutoff. Even these ones compressed at high bitrates. This spectrum hole is audible and very unpleasant. This plugin helps a bit. Old mp3s made from the vinyl or the magnetic tape may also sound better with these "steroids". For old mp3s youll probably need to set filter to 0.1.

2. Adds some even harmonic distortions (actually nonlinearity), that sounds nice. Valve amps introduce even harmonic distortions (although differnt way) Look at audiophile pages for more info (well, mp3 format is not an audiophile stuff at all, but... welcome to the real world...).

3. Adds simple, but nice 3D echo (concert hall or church like). Most of echo plugins sounds too hard and aggresively for me. This one does not.

4. Extends stereo.

USING:

There are currently two versions of plugin - XMMS plugin and stdin/stdout. Stdin/out plugin is completly independent of XMMS plugin. It even stores its configuration in a separate file (~/.crystalityrc). Stdin/out plugin is alpha code, so some features are missed. You cannot reopen configuration dialog after closing without restarting plugin, there are no "save config", "load config" buttons. Configuration is loaded automatically on startup and saved on exit, either on normal finish or ^C. You can disable GUI with -g option (useful in scripts).

Because this plugin adds some sounds at high frequencies, you will probably need to decrease treble level on your amplifier. Plugin does not perform normalization, so you should slightly decrease signal level in XMMS equalizer (NOT volume slider on the main panel). Setting sliders to the maximum is generally a bad idea (well, except the filter, where that setting is useful).

PERFORMANCE:

It eats about 15% of CPU on my AMD K6-2/400 and optimization is still possible, this is not highly optimized code.

INSTALLATION:

Distribution contains binary version of XMMS plugin library and stdin/stdout plugin executable (Linux i586, glibc 2.1.3). You may copy plugin library file (libcrystality.so) into XMMSs Effect directory and executable (crystality-stdio) to /usr/local/bin or any location you prefer. For default locations simply type:

make install

and thats it.
You may also build crystality from the source.

make buildinstall

typed as root in the source directory should be all you have to do.

This plugin was my first small step in gtk programming, so dont expect any wonders, GUI is actually a quick hack to hardcoded settings. I am not a GUI programmer.

Prostat software is a statistic tool for Squid.

HOWTO

Archive prostat_1.3.tar.gz contains very little documentation so heres the extra short manual for how to use prostat:

1. install prostat package
2. make your own copy of /usr/local/prostat/prostat.conf and edit it as you want (or edit directly /usr/local/prostat/prostat.conf)
3. run

prostat +g

(or just prostat in case you do not make copy of prostat.conf)

Example:

cat /var/log/squid/access.log.0 | prostat +g/usr/local/prostat/myconf.conf -

this produces statistic for entries in rotated log using options stored in /usr/local/prostat/myconf.conf file (option LOGFILE is ignored while prostat (in this example) is taking log data from stdin)

Note: do not insert space after +g option

Tips:

- use prostat and crontab to generate statistic automaticly as often as you want
- look at analhead.h in source prostat_1.3.tar.gz archive for some information about command-line options

smixer is a command-line and scriptable program to control and display the mixer volume levels on a sound card in linux. smixer is ideal for setting mixer settings on startup or to switch between multiple configurations quickly.

Distrubution of smixer is under the GNU GPL. See the "COPYING" and/or smixer.c file for more information.

Usage is explained very good in the man page.

smixer may be invoked with the following command-line options:
-a When printing current settings include all devices.
-p Print out the current mixer settings, then exit.
-f file Process commands from file, then exit.
[no options] Process commands from stdin (interactive or from a pipe), then exit.

KSayIt is a small KDE3 utilitiy for Linux that simply speaks a given textfile in a very high quality, i.e. sound and pronounciation of the spoken text should be as (human) natural as possible.
To achieve this, KSayIt uses natively Text-To-Speech systems like MBrola, any TTS system that can be controlled via a command line or any TTS system that is supported by the upcoming KDE TTS system (i.e. Festival).
KSayIt offers three user interfaces: A simple text editor window in which you can enter or paste text that should be spoken after pressing a play button, as well as an icon in the systemtray that starts to speak by a single mouseclick the actual content of the clipboard (if it contains something that looks like text).
As a KDE application it offers also a DCOP interface for the say and shut-up action (see kdcop). Finally KSayIt provides an effectstack to postprocess the sound of the voice (currently only a Freeverb effect is included)
Enhancements:
- KSayIt now interfaces to various TTS systems via loadable modules (plugins).
- Currently the following TTS plugins are in the package:
- Native support for MBrola/txt2pho.
- Support for any user defined command that accepts text from stdin, therefore KSayIt can now speak languages other than German.
- Support for the upcoming KDE TTS Daemon (KTTSD is part of the kdenonbeta package).
- Additional controls (Pause, Resume, Next Sentence, Previous Sentence, if supported by the plugin).
- Audio Effects are also plugins now.

Pod::PlainText is a Perl module that can convert POD data to formatted ASCII text.

SYNOPSIS

use Pod::PlainText;
my $parser = Pod::PlainText->new (sentence => 0, width => 78);

# Read POD from STDIN and write to STDOUT.
$parser->parse_from_filehandle;

# Read POD from file.pod and write to file.txt.
$parser->parse_from_file (file.pod, file.txt);

Pod::PlainText is a module that can convert documentation in the POD format (the preferred language for documenting Perl) into formatted ASCII. It uses no special formatting controls or codes whatsoever, and its output is therefore suitable for nearly any device.

As a derived class from Pod::Parser, Pod::PlainText supports the same methods and interfaces. See Pod::Parser for all the details; briefly, one creates a new parser with Pod::PlainText->new() and then calls either parse_from_filehandle() or parse_from_file().
