Simple Aggregator is a Web-based news aggregator. It retrieves feeds using Mark Pilgrims Ultra Liberal feed Parser, making full use of its advanced features. It stores the feeds in a MySQL database, and displays news via a PHP frontend.
Enhancements:
- the backend is now ready for categories (planned for the next release)
- the feedsloader script now uses threads for much better performance
- the feedsloader script now periodically cleans up read entries
- the feedsloader script now traps feed encoding errors
- added OPML import and export for feeds
- moved CSS style sheets to a common external file
- small fixes mainly to the user menu links

The Net::IMAP::Simple library provides a simple-to-use, yet feature-rich Perl to IMAP API.
Enhancements:
- Fixed error in sample code within the POD documentation identified by Matthew S. Hallacy

Simple scAnning Tool is a simple and fast network scanner. Simple scAnning Tool is used to identify network devices and services. The identification is based on recieved data such as banners.

Usage:

sat.py [options] < file_name/ip_range >
sat.py -r [-f < file >]
sat.py -u [-o < host:port >]
sat.py -h

Options:

-i scan ip range, example: 10.1.1.1-10.1.1.2,10.1.2.2
[default]
-t scan targets from file
-n scan targets from file with nmap grepable output format
(nmap switch -oG)
-p < port_range > port range to scan, example: 1-1024,3333,4000-5000 [default
23]
-T scan TCP ports rather then UDP [default]
-U scan UDP ports rather then TCP
-4 scan via IPv4 rather than IPv6 [default]
-6 scan via IPv6 rather than IPv4
-H < number > maximum number of threads [default 100]
-O < file_name > set the output file name [default sat.log]
-V verbose scan mode
-c < file > specify the config file [default sat.conf]
-l < file > specify the srules file [default sat.srules]
-r restore aborted scan
-f < file > specify the restore file [default sat.restore]
-u update srules file from the net
-o < host:port > set the HTTP/FTP proxy for updater
-v show programs version number and exit
-h show this help message and exit

Pod::Simple::Subclassing is a Perl module that can write a formatter as a Pod::Simple subclass.

SYNOPSIS

package Pod::SomeFormatter;
use Pod::Simple;
@ISA = qw(Pod::Simple);
$VERSION = 1.01;
use strict;

sub _handle_element_start {
my($parser, $element_name, $attr_hash_r) = @_;
...
}

sub _handle_element_end {
my($parser, $element_name) = @_;
...
}

sub _handle_text {
my($parser, $text) = @_;
...
}
1;

This document is about using Pod::Simple to write a Pod processor, generally a Pod formatter. If you just want to know about using an existing Pod formatter, instead see its documentation and see also the docs in Pod::Simple.

The zeroeth step in writing a Pod formatter is to make sure that there isnt already a decent one in CPAN. See http://search.cpan.org/, and run a search on the name of the format you want to render to. Also consider joining the Pod People list http://lists.perl.org/showlist.cgi?name=pod-people and asking whether anyone has a formatter for that format -- maybe someone cobbled one together but just hasnt released it.

The first step in writing a Pod processor is to read perlpodspec, which contains notes information on writing a Pod parser (which has been largely taken care of by Pod::Simple), but also a lot of requirements and recommendations for writing a formatter.

The second step is to actually learn the format youre planning to format to -- or at least as much as you need to know to represent Pod, which probably isnt much.
The third step is to pick which of Pod::Simples interfaces you want to use -- the basic interface via Pod::Simple or Pod::Simple::Methody is event-based, sort of like HTML::Parsers interface, or sort of like XML::Parsers "Handlers" interface), but Pod::Simple::PullParser provides a token-stream interface, sort of like HTML::TokeParsers interface; Pod::Simple::SimpleTree provides a simple tree interface, rather like XML::Parsers "Tree" interface.

Users familiar with XML-handling will find one of these styles relatively familiar; but if you would be even more at home with XML, there are classes that produce an XML representation of the Pod stream, notably Pod::Simple::XMLOutStream; you can feed the output of such a class to whatever XML parsing system you are most at home with.

The last step is to write your code based on how the events (or tokens, or tree-nodes, or the XML, or however youre parsing) will map to constructs in the output format. Also sure to consider how to escape text nodes containing arbitrary text, and also what to do with text nodes that represent preformatted text (from verbatim sections).

SIB (Simple IPX Bridge) is able to tunnel IPX and IP frames received by your Ethernet device via UDP over the Internet. It is able to put the interface it listens on to promiscous mode, so all frames (not only broadcasts, and frames for the tunneling server) can be received.
Actually every 802.3 frame can be tunneled, but SIB only tunnels IPX frames per default (this can be changed via command line). SIB also filters SMB over IPX, to reduce network traffic (this can be disabled too).
Additionally SIB takes care which frames belong to local MAC addresses and sends only broadcasts and frame to non-local MACs to the remote host.
A non-plus-ultra is, that SIB can compress every frame it tunnels via LZO, but you must have LZO library installed.
You may ask yourself: "Why should I need this?" Well, there are lot of answers, but the main reason is: FOR GAMES. Even with KALI for Windows ($14.99) and KALI cracked 1.2 ($0 - but bugs bugs bugs) there is no real WHOLE NETWORK to WHOLE NETWORK connection program which can tunnel IPX, filter SMB, compress it, and works with 2.4.0. And EVERY new game (for Windows) uses IPX for "network" (or should I say Internet ;-) games. (RA2, Q3, HL...)
Enhancements:
- fix for "divide by zero" bug on alpha
- fixed hostname resolver
- added option to set local UDP port
- added option to bind to an specific local IP
- MAC lists flushed on SIGHUP

Simple Firewall is a easy tool for administration users and access control. This tool is made for Linux. Using iptables for packet filtering Write in perl Save rules with xml. That can be run in bash shell and web interface via webmin.
Enhancements:
- Perform reconfigure squid conf for all linux distros
- Fix script init for all linux distros
- Add new menu vpn
- Implemet and integrated PPTP VPN Software
- Modified install script

Graphics::Simple is a simple , device-independent graphics API for Perl.

SYNOPSIS

use Graphics::Simple;

line 100,100,200,200;
circle 50,50,25;
stop(); clear(); # Wait for a button press, clear the page

Ever had a Commodore C-64 or Vic-20 or some other of the machines of that era? Where doing graphics was as simple as

line 20,20,50,30;

and you didnt have to go through things like XOpenDisplay etc.

This module tries to bring back the spirit of that era in a modern environment: this module presents a simple, unified API to several different graphics devices - currently X (using Gtk and Gnome) and PostScript.

The interface is primarily made easy-to-use, starting from the idea that the above line command must work. Therefore, it exports most of the primitives by default (you can turn this off).

However, everything is not sacrificed in the name of simplicity: believing in "simple things simple, complicated things possible", this module also allows multiple windows (all the primitives also work as methods of window objects) as well as raw access to the underlying devices - although the device-independence is then lost. In future plans are some sort of interactions with the devices with which it is possible as well as the addition of more devices.

The use command currently accepts the forms

use Graphics::Simple;
use Graphics::Simple qw/line circle/;
use Graphics::Simple 300,400; # portrait paper
use Graphics::Simple 300,400, qw/line circle/;

i.e. the optional size of the default window first and then normal Exporter arguments.

Graphics::Simple has several different back-ends, currently GnomeCanvas, TkCanvas, PostScript and (not fully working yet) Fig. Other backends are expected.
To start Graphics::Simple with a given backend, you should set the environment variable GSIMPL to the value, e.g. by running your script with the command

GSIMPL=PostScript perl gt1.pl

or by setting the environment variable permanently in your shell, by

GSIMPL=PostScript
export GSIMPL

or

setenv GSIMPL PostScript
