[KI] Measuring Bandwidth Usage for A Spesific Site with Wireshark

Last week, I got a task again from Mr.Budi in Information Security class. The task at this time is measuring bandwidth usage when we log in and use some popular sites, such as Facebook or Gmail (the examples he mentioned). We were directed to use the World’s Most Popular Network Protocol Analyzer: WIRESHARK. I think its developers were too narciss gave a slogan like that for their ‘art work’ -_-” FYI, this (actually) interesting application has been existing for almost two year in my laptop without I used. Haha…okay, let’s we begin and pace yourself to read my exlporation note! (halah)

Assumption: Wireshark has already installed. Please Googling to get to know about it ๐Ÿ˜€

#1: Open Wireshark

First of all, if you are using UNIX family, log in as a root from your Terminal and run Wireshark by typing wireshark. In Windows, you don’t need to do that.

#2: Configure the caption filter

Click on menu Capture -> Interface, and choose an interface that you want to monitor, then click Options. In my case, my LAN connection was viewed by “eth0”, so I clicked the Options button beside it. After the Capture Option window had appeared, I entered this code into Capture Filter combo box:

host http://www.facebook.com and host 192.168.0.2

then click Start. If a confirmation dialog box appears, click Save and click Packet Range at “All packets” option.

[Seri Open Source] Ubuntu Portable

penguin-versus-jendelaSudah pernah mencoba Ubuntu Portable? Kalo Anda ingin bermain sistem operasi gratisan ini tapi belum siap meninggalkan Windows Anda beserta program-programnya, aplikasi ini bisa jadi satu pilihan yang bijak. Ubuntu Portable adalah satu lagi bukti bahwa mazhab open source selalu bisa ‘berdamai’ dengan produk propietari. Setelah pengembangan OpenOffice yang kini sudah dapat membuka file berformat docx, Virtual Box terbarunya yang bisa lincah menjalankan Visual Studio 2008, Wine yang terus bertambah kompatibilitasnya terhadap software-software Windows, dan sebagainya, pengembang open source pun menggebrak dunia dengan sistem operasi yang dapat dijalankan sebagaimana halnya aplikasi berjalan di atas sistem operasi lainnya, tanpa mesin virtual maupun ‘framework’ lain!

Anda pun tidak perlu membuat komputer Anda menjadi dual boot, menginstall VMWare, memasukkan CD Live Ubuntu, atau cara ‘repot’ lainnya. Cukup menginstall master Ubuntu Portable seperti Anda melakukannya terhadap software yang biasa Anda akses dari menu Start di Windows.
