MAMPU-OSCC (Open Source Competency Centre)

What is OSCC ?

OSCC is stand for Open Source Competency Centre and it is a part of MAMPU (Malaysia Administration and Modenisation Planning Unit). MAMPU is one of the government agency under Malaysia government. OSCC are providing a services that based on a Open Source. It is responsible to make an implementation of open source software in a government sector. OSSC are offering a lot of benefits to civil servant that working especially in a IT field. One of the best thing is they are offering a FREE fees training cost. :-) If you seat for Linux Fundamental training at the any training provider, at least you need to spend RM thousand. But, at OSCC you don't need to think about fees.



Me At OSCC

I'm one of the lucky person i guess chosen to attend the Linux Fundamental courses at OSCC on 17 April - 18 April 2007. It is not easy to be invited because there are so many government staff out there waiting for their turn. The two days course give a lot of information to the trainee, meet new friends and so on. The facilities are good, with the HP Compaq dc7700 CMT and powered by Ubuntu 7.04 64bit (Feisty Fawn), it is a very good experience and exposure for me to improve my skills and knowledge.

MC - Midnight Commander

What is Midnight Commander?

DESCRIPTION
GNU Midnight Commander is a directory browser/file manager for Unix-like operating systems.

I'm learning something new during my training at OSCC. It is Midnight Commander a Linux file browser. Basically, it seems like Windows Explorer but the interface is less icon and less graphical look compared to Windows Explorer. To use MC, you can just use the given function key F1 until F9. Even, it's more to command line look, user still can use mouse to use it. Easy huh? Really2 easy la i can say. :)


Install MC if it is not installed yet on your machine. How to install? It's simple. I'm using Ubuntu when I'm write this post.


GUI installation
System > Administration > Synaptic Package Manager > Search type MC > Double click MC > Install

Command line installation
root@training20-desktop:/home# apt-get install mc

DONE!

I was searching on the net and found this software. Great! It's for Linux. So, i have install it on my Linux server. I'm using yum to install it. After the installation is finished, then i try to use this software. See what this download accelerator can do. There are no complex configuration that you need to do. All you need to do, is just enter a few easy command based on the given manual on ProZilla website. I'm using a command line base ProZilla . There are also another ProZilla version that called ProzGUI. This type of ProZilla are using graphical interface. For me, i do prefer use command line as it can improve my skills on mastering the command line. I have tried to remotely (SSH) download the AVG 7.5 from Grisoft (avg75free_446a991.exe) using ProZilla.


ProZilla Usage

1. Open a linux terminal

3. Press Enter and then the file will be downloaded to your machine. The below screen shows
how the download accelarator works.


This below are the ProZilla information on my server

Summary : Advanced Linux download manager
Description :
ProZilla is a download accellerator program written for Linux to speed
up the normal file download process. It often gives speed increases of
around 200% to 300%. It supports both FTP and HTTP protocols, and the
theory behind it is very simple.

The program opens multiple connections to a server, and each of the
connections downloads a part of the file, thus defeating existing
internet congestion prevention methods which slow down a single
connection based download.

ProZilla also supports file download resuming, and ftpsearch for
fastest ping times.
