Arnos IPTABLES firewall script was initially written because I needed to protect my single-homed Linux machine at work. I wrote it at the time I couldnt find any script that really satisfied my needs except for one that was written by a guy called Seven.
I helped him for several months with the work on his script by suppling patches, reporting bugs etc. In this period I was fortunately also able to master scripting for iptables myself because soon Seven discontinued his work, I never got to even talk to the guy ever again. At that point I decided to continue his work, or actually I started my own branch based on his script.
In the summer of 2002 I finally got an ADSL connection at home. Initially I used the iptables firewall that came with the great ADSL4LINUX-package (http://www.adsl4linux.nl). But it didnt take me long to come to the conclusion that their iptables firewall lacked important features like port-forwarding and flexbility with "trusted hosts" etc.
I also didnt like the fact that I had to use a different firewall for my home machine and the machine at work. This made me decide to use some of the ADSL4LINUX knowledge to implement ADSL support.
By now (about 1 year later as of writing) there are only few remnants left of Sevens original script and many, many, many improvements were applied. One major improvement is the ADSL and NAT support (Check the features page with the specifiations of my firewall). For version 2 (alpha) I plan to completely rewrite to script to make it more flexible and to increase the usability for others.
Main features:
- Very secure stateful filtering firewall
- Both kernel 2.4 & 2.6 support
- It can be used for both single- and multi(eg. dual)-homed boxes
- Masquerading (NAT) and SNAT support
- Multiple external (internet) interfaces
- Support multiroute NAT & SNAT (load balancing over multiple (internet) interfaces)
- Port forwarding (NAT)
- Support MAC address filtering
- Support for DSL/ADSL modems
- Support for PPPoE, PPPoA and bridging modem setups
- Support for static and ISP assigned (DHCP) IPs
- Support for (transparent) proxies
- Full support for DMZs and DMZ-2-LAN forwarding. You can also use it to isolate your eg. wireless LAN.
- (Nmap)(stealth) portscan detection
- Protection against SYN-flooding (DoS attacks)
- Protection against ICMP-flooding (DoS attacks)
- Extensive user-definable logging with rate limiting to prevent log flooding
- Includes options to optimize your throughput
- User definable open ports, closed ports, trusted hosts, blocked hosts etc.
- Log & protection options are both highly customizable
- Support for custom iptables rules in a seperate file
- It can be used with chkconfig runlevel system (eg. RedHat/Fedora)
- Main focus on TCP/UDP/ICMP but additional support for *ALL* IP protocols
- It works with Freeswan IPSEC (VPN) & SSH Sentinel (http://www.freeswan.org) (+virtual IPs)
- It works with PoPTop PPTP (http://www.poptop.org)
- It works with UPnP
- DRDOS protection/detection (experimental)
- Its easy to configure
- And much more.
Enhancements:
- This release fixes a nasty bug in the NAT forwarding rules that caused using subnet-source-restrictions not to work.
- It adds an extra rule to the DHCP server section to allow packets from DHCP servers in the same segment.
- There are several plugin updates.
- A Racoon IPSEC VPN plugin and a transparent DNAT plugin have been added.

Relay-bot is a program we initially wrote because our group of friends that hang out on one channel could never seem to all stay on EFnet, and even if we could EFnet was splitting so badly at the time that it was unusable. However, we couldnt readily switch to another network because not everybody is always online and a few people wanted to stick with EFnet because there were other friends of theirs still there. So, relay-bot was born. It allowed us to split our channel across 2 (actually, 3 or 4) different IRC networks fairly effectively.
You[l need a copy Of Perl since perlay bot is written in Perl. Youll also need a copy of Net::IRC.
Theres currently no real installation routine; just untar the tarball, edit "relay-bot.config" and run "relay-bot.pl".
Enhancements:
- relay-bot.config: Fixed small issue in example config file
- BUGS, relay-bot.pl: Prepping for update to a new release

Text::TemplateFill is a Perl module for formatting of reports with templates from files, use for I18N.
SYNOPSIS
use Text::TemplateFill;
my $tmpl = new Text::TemplateFill;
$tmpl->SetOpt(BaseDir => "paras/$Country");
$tmpl->SetOpt(ErrorFunction => &LogMsg, LineTerminator => "rn");
# Must read all the files before printing a paragraph
$tmpl->ReadPara(Header, "head");
$tmpl->ReadPara(FirstPage);
$tmpl->ReadPara(Footer);
$tmpl->ReadPara(Body);
$tmpl->SetOpt(StartPageTag => Header);
my ($a, $b, $cn, $d) = (a, letter b, ACME Inc, 4.92);
$tmpl->BindVars(NameOfA => $a, B => $b, CustomerName => $cn, VarD => $d);
print $tmpl->GeneratePara(FirstPage); # Optional - since we want a specific 1st page
print $tmpl->GeneratePara(Body);
... $a = ...; $b = ...
print $tmpl->GeneratePara(Body);
print $tmpl->CompletePage;
Main features:
- I18N formatting support, eg: decimal comma in France
- I18N date support
- Automatic page breaks
- Variables are registered, not passed to each GeneratePara
- Items of text (paragraphs) that are output are initially read from a text file.
- Calculations may be defined as part of the paragraph definition in the file.
- Optional use of your own Error reporting code
- Variables can be formatted by the full power of printf
- Automatic page/paragraph counting
- Output is a string that may be then written anywhere

AntUnit is a library of Ant tasks that was initially developed to write tests for Ant tasks without resorting to JUnit. Apache AntUnit makes it easy to turn an existing build file that exhibits an error into an AntUnit test.

Tests are written as targets in a build file using assertion tasks provided by AntUnit. The antunit task executes targets in a collection of build files and supports custom listeners in a manner similar to the junit tasks formatters.

NetBSD LiveCD is a bootable ISO image contains NetBSD 3.99.7 and allows you to boot NetBSD/i386 -current without having to install to a hard disk.

The LiveCD was initially intended to be a rescue cdrom, but is now capable of much more.

The default desktop environment is KDE. But there is another window manager available: pekwm.

The LiveCD will automatically try to obtain an IP address via DHCP. If that fails, you must manually configure your network settings. For information on this, please see the NetBSD Guide.

There are two users: root and user. The password for both is NetBSD. If you are logged in as user, you can use sudo(8).

Tk::SplitFrame is a geometry manager for scaling two subwidgets.

SYNOPSIS

use Tk;

use Tk::SplitFrame;

my $MainWindow = MainWindow->new();

my $SplitFrame = $MainWindow->SplitFrame
(
-orientation => vertical,
-trimcolor => #c7c7c7,
-background => white,
-sliderposition => 60,
-borderwidth => 2,
-sliderwidth => 7,
-relief => sunken,
-height => 100,
-width => 100,
-padbefore => 0,
-padafter => 0
);

# Values shown above are defaults.

my $LeftLabel = $SplitFrame->Label (-text => Left);

my $RightLabel = $SplitFrame->Label (-text => Right);

$SplitFrame->pack (-expand => true, -fill => both);

$SplitFrame->configure (-sliderposition => 22);

Tk::MainLoop;

A SplitFrame is a geometry manager for the two subwidgets instantiated against it. It has a sliding divider between them which, when moved, resizes them so that they each remain in contact with it.

The divider can be arranged vertically or horizontally at create time. The children our arranged in the order that they are instantiated, from left to right or from top to bottom. After instantiation, the order is fixed. The children should NOT be packed or placed, the split frame is responsible for this.

The split frame will adjust itself initially to the preferred size of the children.
It is a basic frame itself and can be packed or placed wherever needed in other frames or toplevel windows.

iLeech is a Mac OS X application that will connect to an iTunes 4.0. Introduced in iTunes v4.0 is the ability to share your playlist with other iTunes users.

This is accomplished locally using Rendezvous/zeroconf/mdns/whatever, or if you know the IP address of a machine you can access its playlist via daap:// (provided port 3689 is open). However, you can only stream the music from the iTunes host -- no copies are made on your machine.

iLeech will connect to an iTunes host, display their playlist, and allow you to copy the files to your local drive. It can be downloaded by clicking the "Download" button from the navigation bar.

And all I can say is "Wow". In my wildest dreams I would not have imagined the reaction/attention my simple little Java/Cocoa application would receive. When I initially released it, I had honestly never imagined more than a couple of dozen people would be interested in it. Call me naive if you will, but that is the truth on my end. But that idea has certainly been shattered during the past week, as in the first 4 days the page received an overwhelming 9,399 page views (and 2,147 downloads)
