Move to DigitalOcean

Last week I got a message that offer free bunch of stuff, Github Pro, SimpleDNS, Free Domain, etc. The offer was called Github student developer pack. I registered with my collage email account and won the offer.

DigitalOcean Free Credits

BOM! I accepted, I got free 100 USD credits. I was so excited back then. I will use the Github student pack for research purpose, for making great apps. To cut my cost too, I moved this blog from iwStack to DigitalOcean.

Happy Coding

What is the CVE-2014-6271 bash vulnerability, and how do I fix it?

Recently, there have been news going around regarding “CVE-2014-6271″ (See USN-2362-1), which is a vulnerability in Bash. How do I know if I am affected by this, how can I fix it, and why should I care?

What is Bash?

Bash is the default interactive shell in Ubuntu. When you are interfacing with the terminal (either through the terminal emulator, over a tty, or ssh), you are generally typing commands that bash will read, and execute. Even if you do not use the terminal at all, you still have Bash.

On Ubuntu, /bin/sh is not bash (it is dash). Only bash is affected by this vulnerability. [click to continue…]

Beruntung, gue bisa ngelihat supermoon itu, meski agak nyesel soalnya gak bawa kamera yang agak bener buat ngambil gambarnya.

Gambar ini diambil melalui kamera HP Sony Android Xperia Sola. [click to continue…]

Solve Could not resolve ‘security.debian.org’ DNS Hostname Problem

Have you ever using apt-get update for the first time in Virtual Machine and return

The troubleshooting I made for the first time was change the /etc/apt/sources.list

but what happen?

This still return same.

Fool me, The problem came from DNS hostname. The default hostname was my FQDN and my FQDN’s DNS still not yet configured.
