GeForce 9600GT 512MB [Overclocking]

Graphics card is much more easier to overclock then a PCU.
A freeware RivaTuner does the trick.
Each card has Core clock, Shader clock and memory clock and in GeForce 9600GT for instance it's 650/1625/900.
Currently I run it at 701/1752/1000 which gives much better FPS,
RivaTuner allows for monitoring the temperature, its best not to exceed 80C, however GeForce cards can handle up to 120C!!!


My card reaches 65C under load although if i push the specs a bit higher it occasionally crashes.

To test FPS use 3DMark 11 for latest cards and 3DMark 6,7 for older ones.

Intel Core 2 Duo E4500 @ 2.2GHz to 3.25Ghz[Overclocking]

E4500 turn out to be a great when it comes to overclocking.
First of all download CPU-Z and RealTemp to monitor hardware and temperature.
Secondly download Prime95 which will allow to test the processor under 100% load also called stressing.

The best way to overclock PCU is to do so though the BIOS.
To start you can set FSB Memory clock mode to linked and increase FSB by 20-50mhz (that will decrease your ram performance for now). Load the system and prime95 and check the temperature. Here it's done @2.75Ghz





Keep increasing the FSB until the temperature start to reach 67-70C as 72C is max for this Intel processor.If you can afford get different cooler.
After stable PCU, unlinked it from memory (you can also overclock the memory a bit 20-50mhz and give a bit of vol. between 1.8-2.2 - which is max BE CAREFUL!) I run my crossair PC6400 at 1000mhz (800mhz stock) 1.95v

My E4500 is now @3.25GHz (FSB 275x11) but I have seen people with some £20 quid worth of cooling push it towards @3.6GHz.

The current 3.06Ghz CPU gets quite hot after 3H of prime95 stressing. I ignore it as even playing latest games graphics card to most of the work. PCU shouldn't be getting as hot.

Final year project completed.

Project tittle : Development of an interactive computer based training that allows students to learn Bourne Again Shell (BASH) scripting language.

Main reason for the project is the lack of such products. Moreover the end product is also to help students undertaking Operating Systems module at University of East London and is expected to be used as a part of a practical sessions of that module, as well as any interested world wide web user

The application has been build using Adobe Flex Builder 4 and Actions Script 3.0.
The session were .ppt files converted into .avi and converted once more into .swf format which has been implemented in Flex.



The scope for this project is excellent and there is still plenty that is planned to achieve in the future. After all the bugs are fixed and application is stable, rest of the sessions are ready to be developed. That includes some interesting sessions such as Network Security or Firewalls where BASH would be used to automate some advanced tasks. Another crucial thing would be to expand console component not only to accepts strings as ‘cd /home/ and then while accessing ‘pwd’ to display that current directory but far more than that. A console that simulates unix text editor and allow user to write scripts and analyses them. At some point console component would have allocated disk space so that it can emulate file system and user can create, copy and move files which would be very useful in the session where the task is to move the users from one volume to another.
Moreover users could register on the website and keep record of the sessions they have completed and maintain the same emulated environment with their files etc. That will require additional disk space depending on the number of users.
Another aspect to enchant is to index the page with Google and do searching optimization tasks to make the web based training popular on the World Wide Web.
Android is gaining popularity and recently released 3.0 Honeycomb software designed especially for tablets. Tables average screen size is 10’inch and they have flash support (except Apple) therefore the application could be optimized towards tables if needed. (Geere, D. 2011)
Moreover Adobe Air package offers a possibility for converting this already made application to Adobe Air , that means that the application could be downloaded as a standalone application and run even without network connection.
New ideas for further enchantments are coming every day. There seem to be no ending.

Personal Reflections

To conclude the project has been successful even though the result is below personal expectation. Based on the users feedback there is still plenty to improve such as console component and other bits and pieces. There is still few bugs that were found during testing that need to be fixed before proceeding towards creating of more advanced sessions. Overall look of the web based training is pleasurable for the eye and attracts new users, therefore there is a big scope for future enchantments listed above. Due to some constrains there was less time for this project than expected and deadlines were really tight nonetheless successful. If there was anything that I would change with the application is better use of Action Script libraries and use classes such as event. COMPLETE rather than to start timers for each session. The attempt was made to make different way to make it work however Flex Builder version 4 has not been that stable. Time is needed for evaluation and sorting out the application component by component, which eventually will become superb.

Personal Development

Throughout the project I have learnt how to work really hard and meet my deadlines and especially how to use my time efficiently. I have learnt Bourne Again Shell scripting language, Flex syntax and ActionScript 3.0 which is a massive progress for me in such a short period of time. I have also developed the ways to think outside the box while quick research on PowerPoint and then conversion to video and then to flash. It was also very good for me to use these tools. Flex Builder 4 has been designed with the same GUI as eclipse did so it’s much easier for me now to write code in Java or PHP using eclipse after knowing all the tricks and being familiar with the interface and functions.

Sample of the code for session component.

protected function session1_clickHandler(event:MouseEvent):void
{
//clear interaction panel
interaction.removeAllElements();
// start timer and listener
var timer:Timer = new Timer(205000,1);
timer.addEventListener(TimerEvent.TIMER, ses1con1);
timer.start();
// add session .swf file to the loader.
interaction.addElement(loader);
loader.source="sessions/session1.swf";
// play mp3 for the session
snd = new Sound(new URLRequest("audio/session1.mp3"));
snd.play();

}

protected function ok1_clickHandler(event:MouseEvent):void
{
// victory mp.3 play for guessing correct answer
victory.play();
// display that correct answer was chosen
Alert.show("Correct answer! Keep it up!","Good",Alert.OK);
// clear interaction panel
interaction.removeAllElements();
interaction.addElement(loader);
// load session, sound and timer
loader.source="sessions/session1_1.swf";
snd = new Sound(new URLRequest("audio/session1_1.mp3"));
var timer2:Timer = new Timer(95000,1);
timer2.addEventListener(TimerEvent.TIMER, ses1con2);
timer2.start();
snd.play();
}


I would like to thank:

Mike Kretsis who is senior lecturer at University of East London and my project supervisor, without whose help and support throughout, this project would not have been possible.

My lovely partner Margareta for all the support and care she gave me.

All the participants who agreed and evaluated this project, even more for those who were critical.

VmWare Server setup guide with IE8, Windows XP/7 installing Backtrack

VmWare Server setup isn't that too difficult however it may be a bit confusing for someone new to virtualization. I have created step by step guide by the end of which you should have your WM up and running.

Step 1:

Go to http://www.vmware.com/products/server/ to download the product.
You need to register and activate your account to receive a free license number.



Step 2:

After download , install VmWare Server (try to find some place to store all the data for new virtual machines, I have dedicated one partition for my testing)

After installation , click on the VmWare Server Home page icon in your 'All programs menu or desktop shortcut'. You will be warned by the browser that connection is insecure as ie can't locate appropriate certificate. Click to continue anyway. You will be prompted for user-name and password - it's your Windows administrator user-name and password.

Step 3:

Click to add virtual machine:



Step 4:

Select the name and continue:




Step 5:

Select Linux, other 32bit.



Step 6:

Allocate memory, recommended 256-512mb unless you have got 4GB+ RAM. (you may wat to run few vm's at the time)
Allocate volume space , if not sure give it around 8-10GB.



Step 7:

Accept default bridged connection.(You can leave it disconnected from the network if you plan to release any warms etc, a little bit of common sense)




Step 8:

I have selected to use my physical device as I have my os on the DVD, select ISO only when you have got ISO image.(You can edit these settings later, don't worry too much)



Step 9:

Select your CD/DVD Drive patch and don't use Floopy disk. (unless you have to?)
You should see this screen now:



You can see newly created Virtual Machine.



Step 10:

Select console tab and install the plug-in, after that restart IE8.
You would notice that you can't run VM due to the fact that browser still thinks that it's insecure.




Go to internet options - security - trusted sites and add your VM console patch as trusted , in my case that would be : https://valkyrie:8333/ui/ , When you restart the browser IE8 will still flag it as insecure however you Vm console should run:




Hope that helped. Feel free to contact me.

ITU X.800 brief overview

ITU X.800 is a security/threat model for end to end communication.
Standard consists of Planes and Layers as well as security dimensions to provide very efficient Architecture and security for end to end communication.
There are eight security dimensions addresses to network vulnerability which are listed below with brief explanation and a way of how can they be implemented:

• Access Control – as it can be understood by its name it controls the access to services such as routers, switches, firewalls etc. Implementation can be done in the configuration of such network element or host and for example linking authentication server with these elements.
• Authentication – request of proving subjects identity by for instance digital certificate.
• Non-repudiation – as far as I understand this section keeps the logs and has abilities to do some actions.
• Data Consistency – Provides for instance encryption based on our organization file classification to make sure that our sensitive data is protected.
• Communication Security – that’s security between point A and B. Uses of non-obscured protocols such as VPN so that sniffing or eavesdropping becomes very unlikely.
• Data integrity – checks that both incoming and outgoing data is correct – means for instance if we request 308kb we should receive the same size file on the destination host.
• Availability – makes sure that legitimate users have got access to all necessary network elements and application according to what they suppose to do (role).
• Privacy – provides again encryption of data as one way of implementation but also for instance Network Address Translation (NAT) to protect internal hosts and redirect all the incoming traffic to the border firewall.
