Damascus, Syria

opensource — Tue, 24 Feb 2009 17:53:40 +0000

I’ve been to Damascus (damsyik,dimasqh) recently. I flew there with Qatar Airways, leaving at about 2.30am on the 28th of November 2008. The reason I went there was WORK! Not for a holiday, or to meet special friends, or anything fun like that. Here are some photos I took while I was there.

Networking – tunneling with SSH+proxy

opensource — Mon, 16 Feb 2009 13:50:50 +0000

You can use OpenSource tools, such as Secure Shell (SSH), PuTTY, and Cygwin, to create secure connections to almost any resource you need to access.
1. Open PuTTY (get it here!) –> Connection –> SSH –> Tunnels

2. Source port ( for example i put port ‘9090′), select Dynamic

3. Go to session, key in the hostname with port 22 (connection type = SSH)

——————————————————————————————
login as: root
root@207.5.***.151’s password:

BusyBox v1.01 (2006.12.06-11:11+0000) Built-in shell (ash)
Enter ‘help’ for a list of built-in commands.
#
——————————————————————————————
(to be honest, this is hacked box, so don’t ask me for the l/p *winks* )

4. Fire up Mozilla Firefox, then go to Tools –> Options –> Network –> –> Click Settings

5. Tick “Manual proxy configuration” –> Socks Host –> 127.0.0.1 –> port 9090

6. Before tunneling….

Talking about career…

opensource — Tue, 03 Feb 2009 08:14:50 +0000

Working at an early age, I started working at the end of 2001 after four years study in Computing. To everybody out there, don’t start working at an early age. Study while you can, because I found that the life of a career really sucks. Too much commitment. Too much responsbility. Too many problems. Too much depression. If you’re thinking about money, you’re mistaken. You can find money in so many ways, not just by working.

Before this, I was working as an IT executive at one of the private colleges located in Kuala Lumpur. Now, I am working as an IT consultant in Selangor. Do you know what IT consultants do? Talking and babbling. and fighting each other. Nothing more than that. Sucks, doesn’t it? I don’t like just talking and babbling about things. Practical things come first, then we do the theory/documentation. This is the way I’m doing my job now. To the consultants out there…if you think you’re really good at talking, piss off! You achieve nothing but words, no actions!

Microsoft vs OpenSource

opensource — Tue, 03 Feb 2009 00:00:29 +0000

I still remember using Microsoft Windows (Windows Workgroup 3.1) around 1990, if I’m not mistaken. My first PC with Windows I got from my Dad(to abah..thanks,without you..i’m nothing!) . I used to play Prince of Persia on a black and white screen using the old “big” diskettes of the day. For me, Windows is quite good, except for the viruses/spyware/malware always attacking the operating system. To be honest, I’m really tired of this, and around 2002/2003, I started using RedHat 8. Terbang duit aku RM 50 kat one of this chinese guy semata-mata Red Hat 8 . Tak pasal2..haha!

beginning of the system!

This is nothing to do with open source software. It is just a domain. Of course, you will think “why?” I am just a fan of open source. I am currently using Linux (Fedora) for almost five years now. I am still working hard to become an expert at it.

When I’m talking about Fedora, my great guru in Linux (of course not Malaysian, because I found some Malaysian people who think they are good with Linux actually suck) always says “Gentoo ftw (for the win)”. Well for him, Gentoo is not that good :p (lies , damn lies – Renze )

“actually, binary distros should be the dark side, because they are quicker, easier, more seductive”
