Dedicate This Post To Goh & Poh Meng

This post has delayed for 1 week due to my laziness, but the thankfulness are not forgetable. After moving to Singapore to advance my career, I was seperated from my beloved family and friends, and not to forget my favorate pet, Kinky.

To work in an unfamiliar environment with all the new faces, loneliness really strike my feeling to rock bottom. I was feeling down and bored and how I wish my friend can pay me a visit.  I always wanted someone to visit me, because life here really suck, I do not have any entertainment, everyday just sit at home surt net. It's killing me.

When I was despair, this 2 idiot really came for me. I was half joking in MSN asking them to come, they replied without any hesitation and came in the same week.

[singlepic=103,350,250]

Thank you buddy. Even though you 2 are an idiot but I will cherish this friendship. Finally, this song is for you guys, my dear friend.

Playing DOS Game In Ubuntu

Long time since I last play the computer games. I don't know whether everyone feel the same, when I'm getting older, I have lost my interest in playing games, especially those strategy and online games that takes you a lot of time to accomplish.

But recently I have regained that interest and start looking for some very famous RPG games that I played before like 金庸群侠传 and 侠客英雄传. I know these 2 are very very old games, but I still enjoy playing it.

Since I'm using Ubuntu, so I have to install WINE and Dosbox in order to play the game.

1. To install WINE and Dosbox

sudo apt-get install wine dosbox

2. After installed WINE and Dosbox, use WINE to install the game

wine installer.exe

Eg:(Follow the wizard to complete the installation, if you are installing chinese game, change your gnome session to chinese in order to read the chinese character)

3. Once finish install the game, run dosbox

Goto Applications>Games>DOSBox Emulator

4. Then type the following command in DOSBox Emulator

- mount c /home//.wine                           ### Mount C to wine directory

- c:                                                         ### Change to C Drive

- cd DRIVE_C/PROGRA~1/JINGYONG/  ### Go to your game installed directory

- PLAY.BAT                                          ### Execute the game

Eg:

5. Enjoy the game ^_^

*Note: If you encounter "DOS memory range unavailable" error, is because Linux kernel prevents programs (Wine) from accessing the first 64k of kernel memory. To solve this problem, run this command:

sudo sysctl -w vm.mmap_min_addr=0

Migrating User Accounts From Old To New Linux Distribution

Migrating user accounts can be very troublesome when you have a large numbers of users. So, is always recommend to deploy active directory or LDAP.

If your organization didn't deploy centralized user database like AD & LDAP and have large portion of users needed to transfer from Old server to the new one. Don't worry, you don't need to manually key in all the records 1-by-1, there's always a faster way to achieve this by using script.

I have written 2 perl scripts to perform the migration.

• [download#3] (run in old server) - migrate user accounts from old server and generate a library with all the captured user data.
  
  
  
  • Sample library - [download#4]
  
  
  
  


• [download#5] (run in new server) - include the library generated by migrate_passwd.pl and add all the user_account to the new server.

Steps:

1)  Download migrate_passwd.pl in the old server and run it

./migrate_passwd.pl /etc/passwd /tmp/accounts.pm

2)  Then copy the /tmp/accounts.pm to the new server (put this file into the same directory of serversetup.pl)

3) Download serversetup.pl in the new server and run it

./serversetup.pl

4) Done

Lowyat.net being Hack?!

OMG! lowyat.net being hacked?! Just moment ago when I was watching drame that Goh purposely copy from Malaysia to me, my friend Mr. William message me, asked me to open lowyat.net website, he said he couldn't reach it.

So, I helped him and when I go to the website, It seems like the website being hijacked and the  fontpage has been customized by someone. The background of the website has changed, and there is a big title,

Rabbits have infested Lowyat.NET and unplugged it from the Internet! We will be back when the exterminators arrive. Meanwhile, play around in our chatroom..

Seems like this evil "Rabbit" has invaded the biggest forum in Malaysia!

Use firefox browser to do ping and tracert

The title says it all, you can run ping and traceroute in your internet browser. It's can be handy for sys admin to do their troubleshooting without the need to open a terminal/command prompt.

Steps

1. Open up your firefox browser.

2. Bookmark these 2 links and put a “ping” & “tracert” keyword for each.

http://network-tools.com/default.asp?prog=ping&host=%s
http://network-tools.com/default.asp?prog=trace&host=%s

3. To create a keyword for your bookmark,  if you are using firefox, hit <Ctrl> + <B> then search for the 2 URL's that you have added just now. When you found it, right click and choose "Properties" on it and you will see something like this

5. After clicking "Properties", a window will pop up and from there you can see there is a "Keyword" field. So just enter the keyword accordingly.

• "ping" keyword for bookmark http://network-tools.com/default.asp?prog=ping&host=%s


• "tracert" keyword for bookmark http://network-tools.com/default.asp?prog=trace&host=%s

Example:

4. Ok, you are all set. Now try to type "ping www.google.com" or "tracert www.google.com" without the double quote on your browser URL address bar

Example:

5. See, the ping/tracert result is showing in the browser

Quite handy isn't it.

Gnome DO aka Linux Launchy

Ubuntu: Last time when I saw my Windows user friend showing off how fast he's able to launch his application using 'Launchy', I was so impressed and thinking why don't we have similar application running in Ubuntu Desktop. So I did a search and finally I found an application called Gnome Do, a launcher allows you to quickly search for many items in your desktop environment. And it do not only allows you to search items, it also allows you to specify actions to perform on search results.

To install Gnome DO:

Steps

1. open terminal and type

sudo apt-get install gnome-do

2. Once Gnome Do is installed, first you need to manually run the application, then only you can summon it by pressing Super<Windows Key> + Space.

3. Instead of running Gnome-do manually everytimes, you can add Gnome-do to become startup programs. Just go to System>Preferences>Sessions>Startup Programs tab

• Click Add


• Enter any name on "Name:" field


• Enter "/usr/bin/gnome-do" on "Command:" field


• reboot
  

4. Now everytimes you login, Gnome-do will be running on backgroup. So you can summon gnome-do by only pressing Super<Windows Key> + Space

5. Done

To use Gnome-do, press the summon key and type the keyword of the file or application which you wanted to open or run.

Birthday Surprise

Yesterday was my 25th birthday, to think that I do not have any friend and relative here, I thought my birthday will be just like a normal day.

I WAS WRONG, I experienced something that I never experience before during my birthday. Something HORRIFIED.

What happens is, when I am sleeping that night, I felt something pressing my chest and the feeling is like being pressed by a heavy object, the pressure made me hard to breathe and hearing breathing sound whispering on my ears, so I awake from my sleep and trying to move my body but I can't.

So I opened up my eyes and I saw some white object looks like cloud surrounding my chest! Yes, CLOUD! I'm scared to be honest and start chanting "Amitabha" on my mind. The sensation fade away immediately after the chanting.

The feeling is so real yet it's like a bad dream to me, so I also cannot tell whether it's really happened or not. Anyhow, after I'm free to move my body, I continue my sleep eventhough I am scared.

Sweat~!! I don't know why I got so much guts to continue my sleep or maybe I'm just tired..

I think this is what people's called "Ghost Press Bed" in Mandarin and the "Sleep Paralysis" in medical term. To think something like this happened during my birthday, am I just being bad luck or some unknown object want to wish me Happy birthday? ... AMITABHA! AMITABHA
