Dear Admin: "Please Limit POST/GET request Length"

Sun, 25 Dec 2011 16:01:00 -0000

First of all, I would like to say: Happy new year ;) Haha, this is my first post in 2012 and my first post will began with messages to all admins around the world, to limit their request length. Why? Because it can lead to DOS attack, using a simple POST request with specially crafted messages that can led to huge amount of CPU usages.

I don't have to explain the background behind it, because many articles has done a great job of explaining. Here's the related articles explaining the problem:

The most important is the third link, because many sites are using PHP, and so many sites are not yet updated into PHP 5.3, especially shared hosting sites.

Mon, 02 May 2011 23:05:00 -0000

Following the BCA transaction downloader script, my friend asked me to do the Mandiri transaction downloader script.

So, here it is, ofcourse it is in python. The reason I keep doing this in python is that so other user can use and learn python too. Since it is not as suck as the other scripting language and never let me down ;)

#Ganti username dengan username anda
USERNAME = "user123"

#Ganti pin dengan pin anda
PIN = "123123"

#Ganti pake norek anda
NOREK = "1111111111111"

#Hari
DAYS = 7

Mining GMAIL Data

Wed, 15 Dec 2010 22:12:00 -0000

Once I've create a script to monitor application status and send it to my email. And apparently, I need to download all the result to create some graph for analyzing purposes. Luckily, I have python at my disposal, so I can easily fetch email from my Gmail mailbox to some text file and then whipped some awk command to get the stats.

Here's the simple script to fetch the required emails:

import imaplib
import rfc822
try:
    from cStringIO import StringIO
except ImportError:
    from StringIO import StringIO

imap = imaplib.IMAP4_SSL('imap.gmail.com', 993)
imap.login(USER, PASS)
imap.select()
type,data = imap.search(None, 'SUBJECT', '"Push Stats"')
for num in data[0].split():
    typ, data = imap.fetch(num, '(RFC822)')
    text = data[0][1]
    file = StringIO(text)
    message = rfc822.Message(file)
    print message.fp.read()
imap.close()
imap.logout()

I'm simply run the script and redirect the output to get the text file

python gmail.py > data.txt

And then, just process the data.txt as if its a simple text file data

How To Get Users IP Address in PHP

Sun, 23 May 2010 14:05:00 -0000

There are many tutorial to get users IP address, for instance like this or this. The problem is that HTTP_XXX $_SERVER variables is easily spoofed. It's not reliable because the user can fake it with a simple header addition.

The only real solution to retrieve the client IP address is using $_SERVER['REMOTE_ADDR'], unless your website is serving behind reverse proxy such as NGINX or TrafficServer, than you can safely use $_SERVER['HTTP_X_FORWARDED_FOR']
