Fix ShadowBox.js In Internet Explorer 8

Tony Virelli — Tue, 25 May 2010 18:03:23 +0000

So at my office we use ShadowBox a lot.

Well with the release of Internet Explorer 8 our sites that use ShadowBox no longer worked. Oh, they worked in IE6, IE7, FireFox, Chrome, Safari & Opera, but not in IE8 (a.k.a. The Broken Browser!).

So after some Googling around I found this tip:

1. Go to your path where skin.css is on your server: */skin/classic/
2. Open skin.css and add the following lines:

#shadowbox_title {
  border: 0px solid;
}
 
#shadowbox_info {
  border: 0px solid;
}

So there you have it! ShadowBox should work in IE8 for you now!

Make 007 Jealous With RSA Encryption

John Hass — Mon, 15 Mar 2010 22:50:17 +0000

Make 007 Jealous

Public/Private encryption is not a new thing, did you know you can use my favorite swiss army knife to send secret messages to your friends…. Scratch that, I don’t have any friends… Perl Makes this easy with a little module calls Crypt::RSA, yes RSA is under fire for security blah blah, I don’t care, it’s still secure, because Mr. S’s (yes it’s a dudes name) I can’t pronounce nor spell, I know it will be fairly decent, I am almost about sure Mr. S should be Dr. S, but that just sounds evil, so without further ado, public/private key encryption with perl.

Two people in this Article Tony and John, John wants all correspondence encrypted Tony Encrypts.

I am on my new Mac now, so your mileage may very….

sudo perl -MCPAN -e shell
install Crypt::RSA

it asks you about a ton of dependencies, don’t do what your high school guidance counselor told you and just say yes.

Create something to make the keys

#!/usr/bin/perl
use Crypt::RSA;
$rsa = new Crypt::RSA;
if ($ARGV[0] eq "--makekeys") {
	($public, $private) = $rsa->keygen( 
				Size => 2048,
				Filename => "keylock",
				);
	exit;
}

The start of out program generate our rsa key, keylock.private (and keep this private, no touchy no sendy) and keylock.private, send this to everyone

ok send the public key to tony, so he can send us a message…. Tony should create the message now

if ($ARGV[0] eq "--createmessage") {
	$key = $ARGV[1];
	$message = $ARGV[2];
 
	#open the key
	$akey = new Crypt::RSA::Key::Public (	Filename => "$key");
	my $output = $rsa->encrypt(Message => $message,Key=> $akey)|| die $rsa->errstr();
	open ENC, ">message" or die $!;
	binmode ENC;
	print ENC $output;
	exit;
}

One thing that was a gotcha for me was writing the file, I forgot to tell perl to write it binary, since the encryption is all binary, we must write it so. We now have a file called “message” if you try to edit the file, it’s all gobble gook. Tony can now send you this message, and only you can read it, but how?

if ($ARGV[0] eq "--readmessage") {
	$key = $ARGV[1];
	$message = $ARGV[2];
 
	open FILE, "$message" or die $!; 
	binmode FILE;
	my ($buf, $data, $n);
	while (($n = read FILE, $data, 4) != 0) {
		$buf .= $data;
	} 
	close(FILE); 
	$akey = new Crypt::RSA::Key::Private->read(Filename => "$key");
	my $output = $rsa->decrypt(Cyphertext => "$buf",Key => $akey)|| die $rsa->errstr();
	print $output ."\n";
 
	exit;
}

So now we read the file “message” in using our private key, since Tony encrypted the message with our public key, we can now read it with the private key…. So how does this work?

John-Hasss-Mac-Pro:~ john$ ./keylock.pl --makekeys
John-Hasss-Mac-Pro:~ john$ ./keylock.pl --createmessage keylock.public "007 would be so jealous"
John-Hasss-Mac-Pro:~ john$ cat message

John-Hasss-Mac-Pro:~ john$ 
John-Hasss-Mac-Pro:~ john$ ./keylock.pl --readmessage keylock.private message
007 would be so jealous
John-Hasss-Mac-Pro:~ john$

Welcome to the magic of public private key encryption!

Have fun!

Clearing Out Postfix Deferred Mail Queue

Tony Virelli — Fri, 05 Mar 2010 17:06:16 +0000

I had a bit of a situation with my Postfix Mail Queue. Mail stopped sending and the queue built up. When I did a mailq I found a lot of double-bounce@domain.com emails in my queue. I knew it would take forever for those to clear and get the good mail flowing again.

So after doing some searching on Google I found this site:
http://www.cyberciti.biz/tips/howto-postfix-flush-mail-queue.html

It has some of the common Postfix commands, but what interested me was the Perl script to delete mailqs that matched regular expressions.

postfix-delete.pl script

The following script deletes all mail from the mailq which matches the regular expression specified as the first argument.

(Credit: Vivek Gite of cyberciti.biz. His credit: Credit: ??? – I found it on old good newsgroup)

#!/usr/bin/perl
 
$REGEXP = shift || die "no email-adress given (regexp-style, e.g. bl.*\@yahoo.com)!";
 
@data = qx;
for (@data) {
  if (/^(\w+)(\*|\!)?\s/) {
     $queue_id = $1;
  }
  if($queue_id) {
    if (/$REGEXP/i) {
      $Q{$queue_id} = 1;
      $queue_id = "";
    }
  }
}
 
#open(POSTSUPER,"|cat") || die "couldn't open postsuper" ;
open(POSTSUPER,"|postsuper -d -") || die "couldn't open postsuper" ;
 
foreach (keys %Q) {
  print POSTSUPER "$_\n";
};
close(POSTSUPER);

For example, delete all queued messages from or to the domain called double-bounce@domain.com, enter:

./postfix-delete.pl double-bounce@domain.com

Delete all queued messages that contain the word “xyz” in the e-mail address:

./postfix-delete.pl xyz

For more information about this script make sure and checkout http://www.cyberciti.biz/tips/howto-postfix-flush-mail-queue.html

Improve Droid Sound Quality

Tony Virelli — Mon, 01 Mar 2010 18:16:02 +0000

Today I got a text message from a reader wanting to know how to improve the sound quality of their droid.

Here is a quick step-by-step guide to doing that. However, keep in mind that sound quality is a thing of opinion and results may very!

Click the phone icon
Dial ##7764726
Click the Green Phone Icon or Call Button
You will then be asked for a SPC password
Enter 000000 (That is 6 Zeros)
Then click the Verify button
You will then see the programming Menu
Select option 04 or whatever option is titled “Vocode”
By default the option “EVRC” should be selected
To “improve” call quality select “EVRC-B” and click Apply
Then click the back button on the phone
Your phone will then reboot
When it comes back up you are done!

So now you can be the judge as to whether or not your call quality is better.

Be advised that this will cause your battery to drain faster… yes, even faster than it already does!

Update Your Website Copyright With Some Simple PHP

Tony Virelli — Fri, 26 Feb 2010 07:00:24 +0000

Ok, so every year web designers have the all dreaded task of updating the copyright on their designs. This isn’t so bad if you work for 1 company, but if you work for a design firm like I do and have tons of clients websites to update it can be a time eating task.

So to fix this problem I wrote this super small, super easy bit of code. It’s nothing special, but it gets the job done.


$startYear=2010; //Enter the starting year of the copyright.
if($startYear < date("Y")){
	echo $startYear."-".date("Y");
}else{
	echo $startYear;
}
?>

And for the function lovers


function updateCopyright($startYear){
	if($startYear < date("Y")){
		echo $startYear."-".date("Y");
	}else{
		echo $startYear;
	}
}
?>
//Usage: Copyright ©  echo updateCopyright(2010); ?> Company Name

There ya go!

Isn’t making your life easier fun!? I sure think so!

How To Get a Custom Boot Screen on Droid

Tony Virelli — Thu, 31 Dec 2009 06:44:29 +0000

****************************************************************************
UPDATE: FBG Studios.com seems to be down right now. Also the video tutorial is set to private. So until further notice the only instructions are the written.
****************************************************************************

Yesterday I was searching around the web and found this video on fbgstudios.com. It is a tutorial on how to add a custom boot screen to your Motorola Droid. It does require you to root your Droid, but hey, if you are ballsy enough to change your boot screen I bet you already have your Droid rooted!

Here is the video tutorial:

Here is the text tutorial:

1. Make sure that your phone is rooted, if it is not watch this video tutorial: http://www.youtube.com/watch?v=4QVm4SxH8Pw

2. Download an animation and make sure that it is named bootanimation.zip.

Here are some you can download (but there are plenty more online so you can google them):

Nexus One
3d Android
R2-D2 (MAKE SURE TO RENAME IT TO “BootAnimation”)

3 OPTIONAL

* a) To customize the animation just add the text or image you want. Remember that each picture is a frame and that each frame moves very quickly so if you want solid text make sure to put it on for more than 15 frames. Also keep in mind that there are two animations (part0 and part1) and part is the one that repeats.
* b) Now highlight folders part0 and part1 as well as desc.txt file.
* c) Using WinRAR right click and select “Add to archive…”. IMPORTANT: Make sure that the file is named “bootanimation” and the file format is .zip!

4. Connect your USB on your Droid and make sure it is mounted!

5. Go to your SD card of your phone and drag the bootanimation.zip into the root folder.

6. Eject your phone

7. Download Terminal Emulator for you phone then open it up

8. Type in the following (EXACTLY THE WAY YOU SEE IT; press enter after each line):

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
dd if=/sdcard/bootanimation.zip of=/system/media/bootanimation.zip
Reboot

9. Your phone will be rebooted and now you can enjoy your new custom bootscreen!

Again I want to give credit to FBG Studios.com, so make sure and visit their site.

Here is a direct link to the tutorial: http://fbgstudios.com/how-to-get-a-custom-boot-screen-on-droid/2009/12/

Using NMAP To Detect Server Type

John Hass — Mon, 28 Dec 2009 14:33:55 +0000

When you talk power utilities on any *nix it’s hard to skip nmap. Ever since it’s introduction nmap has been used for good and evil. If you’ve ever had a server hacked chances are they used nmap or some sort of nmap code to get the job done. Just how easy is it to detect the server type from nmap? Try my windows 2003 server (I know kick me in the nuts and call me sally).

nmap -A -T4 192.168.10.1

it took over a minute to get the results, but here is what I got.

URL Shortening, for the Faint of Heart

John Hass — Thu, 24 Dec 2009 14:30:53 +0000

Hello, Hello, Hello. Quick tut on bit.ly in PHP, nothing more nothing less (and yes I said PHP not Perl like I am so fond of). In order to use this code you need a bit.ly account. Visit http://bit.ly/account/register?rd=/ to get a login and a API Key.

Here is the function:


function shortenURL($url) {
$login = "yourlogin";
$apikey = "your api key";
 
$newurl = file_get_contents("http://api.bit.ly/shorten?version=2.0.1&longUrl=".$url."&login=".$login."&apiKey=".$apikey);
$content = json_decode($newurl,true);
$error = $content["errorCode"];
if ($error == 0){
$newurl = $content["results"][$url]["shortUrl"];
}else {
$newurl = 0;
}
 
return $newurl;
}
?>

Just include this file in any script and call

and boom it’s shortened.

Merry Christmas you filthy animal.

Test Your Network With Ping

John Hass — Wed, 23 Dec 2009 14:30:05 +0000

Ping is a great utility to use to test if a server is up or if a server is responding in the correct time, but what if you could use ping to actually test your network infrastructure. Lets call it a “poor mans test”.

Linux ping allows you to specify the number of bytes that are sent to the server your pinging.

ping -s  127.0.0.1

The maximum packet size it 65507, this is 63.9990234 kilobytes, not a very big packet at all, but what if you sent hundreds of them a second?

Enter ping flood.

ping -s 65507 -f 127.0.0.1

To quote the ping man page:

Flood ping. For every ECHO_REQUEST sent a period “.” is printed, while for ever ECHO_REPLY received a backspace is printed. This provides a rapid display of how many packets are being dropped. If interval is not given, it sets interval to zero and outputs packets as fast as they come back or one hundred times per second, whichever is more. Only the super-user may use this option with zero interval.

Here is an example of the output

ping 192.168.10.27 -s 65507 -f
PING 192.168.10.27 (192.168.10.27) 65507(65535) bytes of data.
.
--- 192.168.10.27 ping statistics ---
267 packets transmitted, 266 received, 0% packet loss, time 4321ms
rtt min/avg/max/mdev = 11.476/14.489/30.344/5.301 ms, pipe 3, ipg/ewma 16.245/11.551 ms

If I had lost a packet it should show a packet loss. As you can see, the server is sitting on the same switch as my desktop. It dropped 0 packets and had a rtt of 11.476 ms.

Not bad!
