Early 2107 a lot of people are talking about crypto currency and how much they made by trading them in the exchange, but I don’t really care about crypto at that time and I thought it is just a phase or just a hype to make people fall into a scam scheme…..then in November 2017 bitcoin rise up to $7000 then $8000 then it hit the $10000 mark, I was like “I should have started this earlier”. The funny thing is that my friend already invite me to start mining for crypto currency early 2016, mining is another way of earning crypto currency without the need to buy them on the exchange. So around October 2017 I have got my hand on an Ethereum Mining Rig which as in title says it was from China and you might be wondering why would I get a mining rig from China? and the answer is simple it is cheap compare to what has been offered in my local vicinity and it is already been assemble by the manufacturer so I do not need to take it out of the box and figuring out which cable need to connect to which socket. To cut the story short the box came, I took it out of the box and connect all the necessary components such as monitor, mouse, keyboard, power cord and I switch it on. It came with zero manual and everything is in Chinese (what do you expect? it came from china LOL), so I have to make a few try and error before I manage to change the bios language to English language and Windows 10 are in Chinese as well, no luck in changing that so I just try and error with everything. I manage to start the miner, set my wallet address and let it run for 30 days, the initial speed is about 27 MH/s and the power consumption about 1100 watts. That is another mistake that I did, more than half of my earnings goes to the electricity bills!!! and I thought that I won’t be able to break even in 8 month time if this goes on, so I did a little digging and I found that RX480 can be tune up to 29MH and run at less than 1000 watts by doing a bios mod on the card. The journey begins..

This slideshow requires JavaScript.

Most tutorials online said that I have to do memory strapping, copying the HEX value from 1650 to 2000 timing…tried that and the result is 29.15 MH/s @ 1100 watts. So I adjust the core and memory timing using Afterburner, adjust the fan speed, the power limit and there you go I got it to run 29MH/s @ 1000 watts. I am still not satisfied with this settings as hashing rate increase the heat that the RX 480 produce also increase from 60 ℃ to 76 ℃ and I am turning the room into a sauna + the room temperature of 30 ℃. So here is the steps that I took in order to lower the watts and temperature, here are the list of item that I used and you may get the software by clicking on the list

  1. Ethos 1.2.7 since windows 10 is in Chinese

  1. Atiflash 2.77
  2. ASROCK Pro BTC H81
  3. Intel(R) Pentium(R) CPU G3420 @ 3.20GHz
  4. tigo SSD 60GB
  5. 4GB DDR3
  6. Ellesmere Radeon RX 480 4GB Hynix Memory
  7. Bios to be use China_RX480_4GB_29MH_850w.rom

So lets start the tutorial

    1. Back Up the BIOS before anything turn sideways please save your original BIOS with this if you accidentally bricked your GPU you can always reflash them with the original BIOS.
    2. Download the China_RX480_4GB_29MH_850w.rom
    3. Follow this video from 1stminingrig.com

 

Once everything has been running perfect here are the settings that I used in the local.conf files

maxgputemp 85
stratumproxy enabled
globalminer claymore

Hi, it has been a while since my last post, but today I’ve gained new knowledge that I wanted to store into this archive of mine. It might be useful to some other people, but it certainly is useful to me. Please enjoy the tutorial, share if you like it and leave a comment if you feel I am wrong (I’ll correct it if its true 😀 )

 Installing the FTP Package

1. Update your repository

yum check-update

2. Install the package

yum -y install vsftpd

3. After installation is done, make a copy of “vsftpd.conf” file

cp /etc/vsftpd/vsftd.conf /etc/vsftpd/vsftpd.conf.bak

4. Edit the configuration file with nano text editor

nano /etc/vsftpd/vsftpd.conf

5. Find this line “anonymous_enable=YES” by pressing CTRL+W and change the value to NO to disable anonymous FTP access.

6. Using the same method as the above find “chroot_local_user=YES” and uncomment it.

7. Add the following to the end of the file

allow_writeable_chroot=YES
pasv_enable=Yes
pasv_min_port=40000
pasv_max_port=40100

8. Restart the VSFTPD service and make it start automatically after reboot

systemctl restart vsftpd.service
systemctl enable vsftpd.service

9. Add the FTP service in the firewall-cmd this is to open the FTP port

firewall-cmd –permanent –add-service=ftp
Firewall-cmd --reload

10. Setup SELinux to allow ftp access to the users home directories.

setsebool -P ftp_home_dir on
setsebool -P allow_ftpd_full_access 1

Create a user and assign the home directory

1. For this tutorial I want to create a user without a home directory therefore I use –M instead of –m.

useradd -M mike –s /sbin/nologin
passwd mike

2. Next is to set the home directory for “mike” by creating a new directory

mkdir /var/www/mike
chmod 755 /var/www/mike

3. Once that is complete point the directory to the user “mike”

chown -R mike /var/www/mike

First thing that you guys need to remember is that this tutorial might be a little old since I’ve already left RMIT. Just use this as a reference as it might be a little different from the current system.

    1. Download the latest phpmyadmin from www.phpmyadmin.net
    2. Extract the content into phpmyadmin folder.
    3. Create a “config” folder inside the phpmyadmin directory.
    4. Upload the phpmyadmin folder to .HTMLinfo on yallara.
    5. Open up your browser and open your yallara link which might look similar to this http://yallara.cs.rmit.edu.au/~s<insert your id>/phpmyadmin/setup
    6. Once you are at the page please pay attention to the following tabs/boxes
    7. Image
    8. Create a “New Server”
      1. and you key in the following
        1. host : yallara.cs.rmit.edu.au
        2. port : <the port number that is given when you install your MySQL>
        3. extension : mysqli
        4. authentication type : cookie
        5. user : root <it can be other user that you have created>
        6. password : <your user password>
      2. After all is done and the screen on number 7 reappear, click Save.
      3. Go to your filezilla and login to yallara
      4. Go to your .HTMLinfo folder
      5. Go to your phpmyadmin folder
      6. Go to the config folder
      7. Cut the config.inc.php file and paste it to your phpmyadmin folder (take it out of the config folder)
      8. DONE finish now you can login to your phpmyadmin through your respective URL http://yallara.cs.rmit.edu.au/~sXXXXXXX/phpmyadmin

Security in Computing and IT

Posted: October 22, 2012 in Exam Papers

Its end the of the semester and exam is around the corner next week to be exact here is some sample Web Server and Web Technology paper that I’ve acquired from a good friend of mine back in Malaysia. If any of you need the paper feel free to view it below.

Hi just want to share a review to who ever wants to actually create a “Groupon” Website it is advisable no it is recommended that you AVOID or DON’T use NDOT Deals script as what I can say here it is so bad that it has too many bugs in it.

For example if a customer bought a coupon from the website and in the middle of the transaction your customer internet got disconnected and unable to finish the transaction that need to reply back to the script saying that “Transaction is successful please issue a coupon!”. You as an administrator should have the power to actually issue the coupon manually if and only if this scenario happen, but sadly NDOT Deals script won’t allow you to do that!.

And you cannot actually clear the old transaction if you want to close your account at the end of the month. Clearly to say that NDOT did not do their market research well enough. If you don’t want to loose your money please find other alternative to a groupon clone script or create your own script as I personally say that NDOT Deals is NOT good. I’ve should have know when I read their motto “Dream On, We Deliver” yeah they keep on delivering things that can only be used in dreamland and not reality.

If you guys are wondering on what the hell am I talking about this product is what I am talking about

DON’T BUY IT YOU WILL ONLY REGRET IT! 

The COSC 2432 assignment involves the design and implementation of a website for an Online Fashion Store. The business may be your own or that of a friend, an actual small business or an imaginary one.
The assignment for this subject is 40% of the total marks available and is a hurdle (meaning you have to achieve at least 20% out of 40% for this component).

Overview:
Design a set of linked web pages for a fictitious online Fashion Store. The site should consist of no fewer than 15 web pages with full multi-directional navigation between pages. The site should search function that able to search for the item by typing the generic shirts, pants, accessories, price range, etc. Depending on the search keywords, the site should provide a possible list of products, and then when to each product on the list is clicked, the site should have more details about the selected product (e.g brand, price, size, quantity available, discount available, etc).
Guidelines for Online Fashion Store:

  • Full name of company, location of main office, telephone/fax numbers, e-mail address, Company mission statement and a brief welcome to potential users. Your company should be run by a board of directors, in which case the names/pictures of each should be in your site.
  • Should provide no less than three categories of products.
  • Current running promotion.

Important Information:
You are required to create an Online Fashion Store allowing registered customers to search and order products from the online bookstore. Non-registered users can use the search form, but they are not allowed to make an order until they have registered as a customer.
Returning customers should be given the option to login using existing username and password if they are already registered. If the attempt to login is successful an appropriate welcome message should be displayed. New users should be given the option to register.

A. Registration
Customer registration allows the system to verify all customer details are valid and ensures that all customers have a unique and valid Customer ID. It also allows the system to verify and keep track of all personal details of the customer details.
This page should prompt users to fill a form with fields for
(a) Customer’s name (full name)
(b) I/C number
(c) Gender
(d) Personal status (Married, Engaged, Single)
(e) Work status (Government Sector, Private Sector, Self-Employed, Unemployed, Student)
(f) Home Address
(g) Address for delivery (may be the same as the Home Address)
(h) Phone number
(i) Email address
(j) Username
(k) Password

Email Address
Assume that email addresses must end with either .my, .com, or .net and must not have two adjacent non-alphanumeric characters such as .. or –. It must contain the character @ exactly once and it must have at least two other characters after @.
Username/Password
Both username and password must consist of at least 6 alphanumeric characters, and password cannot have two or more adjacent characters the same (12yuu678 is not allowed because of uu). The user should be told of the correct format for the password.
If any of the fields are empty, an appropriate error message should be displayed indicating the problem. If the username already exists, an appropriate error message must be printed.
The input information for searches, customers, feedback and orders should be written to file searches.txt, customers.txt, feedback.txt and purchaseorders.txt respectively with the format specified below. Your program should verify that no other customer has the same phone-number (to avoid registering the same person twice) and that no two customers have the same I/C number.
Error Message / Acknowledgement
If any of the fields are empty, an appropriate error message should be displayed indicating which fields are left out. If the username already exists, an appropriate error message must be printed. If all form input are valid an acknowledgement page listing all the fields must be printed.
