Using Graphviz and dot language to plot friends and family

2010-12-14 fash

I’ve been using the dotty language for many things, this is a who is who displayer.
iptables rules displayer, open ports, gluster brinks/nodes. netstat ports.,
Wil post more about this later

installing
apt-get install graphviz

View it on a website using mojozoom javascipt

Onkyo web control hack

2009-10-23 fash

Back in 2009 i’ve posted my web controller for Onkyo in a forum.

Several people build on that source and made android/iphones app using this as example.

It uses pfsockopen with raw packets in php.
Spend a lot of work reverse engineering the tcp headers to be send.
Another fun trick was re-using a trick i’ve used for my ipcam controller and dartabase. (Dart game application)

Below a PDF with first page of forum

Onkyo-TX-NR-1007-Webinterface-Programming-_-AVForums Download

I’ve made a alteration in my logitechmediaserver (squeezebox server) which embedded a onkyo volume control part in the gui.

Part of code

// maximum to set volume (0-100) 
// !! some have 64 max????
$volumemax=60;
// (i had to enable this port by going onto the menu's on my Onkyo
// ---- NO EDITING BELOW THIS LINE

// trick browser into staying on same page
$ibrowser = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
if ($ibrowser == false) {
header("HTTP/1.0 204 No Response");
}
// test write to file
//$fp=fopen("test.txt", "wb");
// write to Receiver 
$fp = pfsockopen($receiveripnumber, $receiverlistenport, $errno, $errstr, 30);
//get command from post form
$command=$_POST['cmd'];
//get volume if cmd is numeric
if(is_numeric($command)) 
 {
if ($command > $volumemax) { $command=$volumemax; }
echo $command;
  $vol=str_pad(dechex($command), 2, '0', STR_PAD_LEFT);
  $command="!1MVL$vol";
 }
// Calculate header and datapacket lengths
$length=strlen($command); 
$length=$length+1;
$total=$length+16;
$code=chr($length);
// total eiscp packet to send 
$line="ISCP\x00\x00\x00\x10\x00\x00\x00$code\x01\x00\x00\x00".$command."\x0D";
#fputs($fp,$line,$total);
// write
fwrite($fp, $line);
// rest status part
//    while (!feof($fp)) {
//        echo fgets($fp, 128);
//    } 

fclose($fp);

Staircase pictures

2008-04-08 fash Leave a comment

Maybe you also have a white area to fill, here is a suggestion.

For years we collected picture frames, weird and ugly.
We wanted to have a collection of images in our staircase, to fill the white area.
The images are all something we like, have interest in or are personal.

It needed to be on 3 walls, so here was my first design.

A joke my employer didn’t like

2008-03-26 fash Leave a comment

I worked for a highly secure position in a financial place.

We had to use so-called RSA keys.

These keys we needed to get access to the servers.

That morning i came in office and had the following conversation with the manager:

ME: It’s far too easy to lose my RSA key, so I left it at home.
Manager: So how are you getting any work done?
ME: Well … i can get the login codes from here, while opening a browser to a popular social site. Here is my webcam, pointing to my RSA key.
(For everyone to see)
Manager: …. blank stare
ME: Now i can access it from anywhere!
Manager: … buttt

I recorded the key, so it displayed only a few old codes.
(It was a looping animated GIF, which looked like a webcam picture)

When explaining he laughed. A two minute joke, two hours making it ..

Working to get the Dutch Railways Signs working.

I was working on the backend, but frequently was asked to help working on the boards.

I can’t post any other pictures, because they are revealing to much information

I’ve worked on the boards, backend and a peer2peer VPN solution

Bios password fix

2007-06-30 fash Leave a comment

Don’t know bios passwd anymore?

start debug.exe

o = out
port 0x0070-0x0071	The CMOS and RTC registers (more info below)
# Does not seem related but it works!


-o 70 2E
-o 71 FF
-q

OR

-o 70 17
-o 71 17
-q

Other fixes i’ve used:

Remove cmos battery .. and short the connections with wire.
This CAN completely reset your Bios settings!

Audio CD index

2006-10-08 fash Leave a comment

I’ve got a large Folk Music collection. And i wanted to have an overview of the Audio CD’s (mp3/flac) i’ve got from every Band or Artist.

So I made some PHP scripts and a scraping tool. To get a nice overview.

A part of it looks like this:

Most is auto-generated:

The scraper part needs eyed3 (made at a later date)

Beer crate bottle counter

2002-05-17 fash

Post in 2002 due to screenshot .. dont know when i build it, some years before.

Using 24 pushbuttons and a IO expander, i could count the bottles in a crate. Probably used something like a hef4067 ??

Now i probably use a weight sensor or a beer cap counter using a webcam image.

Notification to email and shopping list printer.

Every bottle had to be placed back upside down so the opening of the bottle would not press down on the button. Later i used springs which could hold a empty bottle elevated above the button. The weight of a full bottle would press on the button.
