Free simple udp software for linux

Simple UDP proxy/pipe is an advanced UDP proxy/datapipe/packets forwarder and modifier with multiple functions.

Multiple clients allowed (you can connect many clients you want to this proxy), creation of ACP files (tcpdump capture files, just like a sniffer), packets forwarding (chat style, each packet is forwarded to all the other clients and server connected), packets injection (the tool opens a specific UDP port where you can send your customized packets which will be sent to the server), hexadecimal visualization and plugins support for the modification and visualization of the packets with some example plugins already included (Zdaemon huffman, Doom huffman, Half-life decoding and one for the replacement of the text strings).

Plugins (which work on both Windows and Linux) are very basic to create and use, just take a look at example_sudp.c for more informations.

LJ::Simple is a Perl module to provide a simple OOP-based API for accessing the LiveJournal system.
Main features:
- Log into LiveJournal
- Post a journal entry
- Edit a journal entry
- Delete a journal entry
Example
The following example posts a simple message into the test LiveJournal using the LJ::Simple::QuickPost method.
use LJ::Simple;
LJ::Simple::QuickPost(
user => "test",
pass => "test",
entry => "Just a simple entry",
) || die "$0: Failed to post entry: $LJ::Simple::errorn";
The next example shows how to post an entry into the test LiveJournal using the complete, object-based, interface:
use LJ::Simple;
my $lj = new LJ::Simple ({
user => "test",
pass => "test",
});
(defined $lj)
|| die "$0: Failed to log into LiveJournal: $LJ::Simple::errorn";
my %Event=();
$lj->NewEntry(%Event) ||
die "$0: Failed to create new entry: $LJ::Simple::errorn";
my $entry=SetMood(%Event,"happy")
|| die "$0: Failed to set mood: $LJ::Simple::errorn";
$lj->Setprop_nocomments(%Event,1);
my ($item_id,$anum,$html_id)=$lj->PostEntry(%Event);
(defined $item_id)
|| die "$0: Failed to post journal entry: $LJ::Simple::errorn";

XML::Simple is a easy API to maintain XML (esp config files).

SYNOPSIS

use XML::Simple;

my $ref = XMLin([< xml file or string >] [, < options >]);

my $xml = XMLout($hashref [, < options >]);

Or the object oriented way:

require XML::Simple;

my $xs = new XML::Simple(options);

my $ref = $xs->XMLin([< xml file or string >] [, < options >]);

my $xml = $xs->XMLout($hashref [, < options >]);

(or see "SAX SUPPORT" for the SAX way).

To catch common errors:

use XML::Simple qw(:strict);

DFA::Simple is a Perl module to implement simple Discrete Finite Automata.

SYNOPSIS

my $Obj = new DFA::Simple
or
my $Obj = new DFA::Simple $Transitions;
or
my $Obj = new DFA::Simple $Actions, $StateRules;

$Obj->Actions = [...];
my $Trans = $LP->Actions;

$Obj->StateRules = [...];
my $StateRules = $LP->StateRules;

my $Obj = new DFA::Simple $Actions,[States];

This creates a simple automaton with a finite number of individual states. The short version is that state numbers are just indices into the array.

The state basically binds the rest of the machine together:

1. There might be something you want done whenever you enter a given state (Transition Table)
2. There might be something you want done whenever you leave a given state (Transition Table)
3. You can go to some states from the current state (Action table)
4. There are tests to decide whether you should go to that new state (Action table)
5. There are conditional tasks you can do while sitting in that new state (Action table)

This structure may remind you of the SysV run-level concepts. It is very similar.
At run time you dont typically feed any state numbers to the finite machine; you ignore them. Rather your program may read inputs or such. The tests for the state transition would examine this input, or some other variables to decide which new state to go to. Whenever your code has gotten enough input, it would call the Check_For_NextState() method. This method runs through the tests, and carries out the state transitions ("firing the rules").

JOpt Simple is a simple, test-driven command line parser for Java programs. JOpt Simple supports POSIX getopt() and GNU getopt_long().
What command line switch syntax does JOpt Simple support?
As closely as possible, JOpt Simple attempts to adhere to the rules of POSIX getopt() and GNU getopt_long(). You can find a brief summary of these rules in the javadoc for class OptionParser.
Enhancements:
- Minor internal changes.

PGPLOT::Simple is a simple Perl Interface to PGPLOT.

SYNOPSIS

use strict;
use PGPLOT::Simple qw(:essential);

die "Must provide a filename.n" unless @ARGV;

my $filename = shift;
chomp $filename;

unless ( $filename =~ /.ps$/ ) {
$filename .= ".ps";
}

set_begin({
file => "$filename/CPS",
});

set_environment({
x_min => 0,
x_max => 50,
y_min => 0,
y_max => 10,
});

write_label({
title => A Simple Graph Using PGPLOT::Simple,
color => Blue,
font => Italic,
});

draw_points({
x => [1, 3, 12, 32, 40],
y => [1, 5, 5, 3, 9],
color => Blue,
width => 20,
});

draw_error_bars({
x => [20],
y1 => [4],
y2 => [6],
terminal => 10,
width => 10,
color => Orange,
});

set_end;

PGPLOT::Simple is a simple interface to the PGPLOT library ala Perl, making simple things easy and difficult things possible.

Why simple? Because it has a simple and intiutive interface to the most common things you will need from PGPLOT, but also allowing you low-level access to the PGPLOT library.
