XpressLiteCoin – Your Litecoin payment gateway

As promised days back on my Tunnelix.com Facebook Page, I would blog about setting up a Litecoin button on your website for payment or donation purpose which I did myself. See on the top right corner of the blog. I would strongly suggest using the XpressLiteCoin payment gateway for such type of transaction. Some days back during the operation JASK, I contributed to the LiteCoin repository and I thought why not set up a Litecoin donation button. The funds received will be used to renew my server hosting and tunnelix.com domain. Below are some instructions to start with.

For some who are not well acquainted to cryptocurrencies, Litecoin is one amongst many and it is a fork from the Bitcoin. Litecoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Litecoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Litecoin Core is the name of open source software which enables the use of this currency.Litecoin

Imagine, you want to receive payments for your business in a more secure way. Of course, when it comes to cryptocurrencies, no one wants to take the risk. XpressLiteCoin is here to provide merchants with a cheap and convenient way to integrate Litecoin in their business payment process. – XpressLiteCoin

How to start with XpressLiteCoin payment gateway?
1. First, you will need to register yourself on the XpressLiteCoin.com website. This is pretty straightforward. Make sure you received the confirmation email once you have to sign up on the website.

Create a Litecoin address.

2. You can create a paper-based wallet but the procedures can be lengthy and you will have to secure your key and record all transactions. However, using the online wallet is pretty simple with Jaxx.

3. After installing Jaxx, you will have the option to create a new wallet.

4. Then, you will have the option to choose the paper-based wallet or an online wallet which is easier.

You can create your wallet and scan the QR code to use the same wallet on your mobile device such as Android, IOS etc..

5. After configuration, you will have an LTC Address.

Merge your Litecoin address with XpressLiteCoin gateway

6. Save your Litecoin address and enter it on the prompt which you received when logging for the first time on the prompt as shown below:

By this time, you should have been able to access the dashboard as a user. Now it’s time for some basic installation on the server.

Some basic installations on the server

7. On the server, install the “npm” package manager:

yum install npm

8. You can also upgrade your version of npm as follows:

npm install npm -g --ca=""

9. Use known registrars for the current version of npm

npm config set ca ""

10. Some installations with npm package manager which are required:

npm install express
npm install request
npm install  body-parser

11. You will also need to download the xpresslitecoin.gz at the following link as shown below :

12. To integrate the XpressLiteCoin on your website, go to the documentation page and/or click on guide. You will notice find the integration.pdf which have a piece of Javascript that will be needed on your application.

13. There are two parameters in the code to tweak: First is the port number your application will be listening and second is the token which you will get from the XpressLiteCoin dashboard on the merchant settings option.

14. Copy the token and insert it at line 10 of the code. Example:

const api_token = "XXXX<Token Value here XXXX";

15. By default, the port runs on 8080. In case, you want to change it, feel free.

16. You will also need to run your application. I would, however, recommend you to have a script on autostart for this service :

node xpresslitecoin.js

17. Since the application need to be inserted as a plugin on your website, you can create a ProxyPass on your web server. For Nginx proxy use the following parameter

location /xpresslitecoin/ {

    proxy_set_header HOST $host;

    proxy_set_header X-Forwarded-Proto $scheme;

    proxy_set_header X-Real-IP $remote_addr;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_pass http://127.0.0.1:8080/xpresslitecoin/;

}

18. For Apache HTTPD ProxyPass, see the documentation here.

Create the payment button

19. By now, you should be able to run the node service with the XpressLiteCoin application. However, to insert a button your website to received payments through the gateway, you will need to insert a few lines on JavaScript codes.

<script type="text/javascript" src="xpresslitecoin.js">
</script>
<button id="xpl-donate"> <img src="LocationToYourImage.png" alt="Please Donate"> </button>

20. An issue that your might encountered if you have CSP enabled which is a good thing. However, you will need to make sure that you have an exclusion on the plugin.


Facebook friend requests – Fake or Real ?

Fake profiles are raining over the Internet especially when it comes to Facebook social media. Since days, I’m receiving so many friend requests. Common, a guy receiving more than 230 friend requests !! I wonder if it’s because of the hackers.mu worldwide popularity symptoms ! Or the haters are going wild against me with this “Facebook Friend request spam mechanism”. LOL!

 

Whilst some may be genuine and others fake, it is very difficult to manage all these friend requests which consumes much time. It’s probably one of the reason I moved to Twitter and create my own Facebook page – Tunnelix.com. So, give a try and click on the like button on my Facebook page. You can still message me on my page as it is much more under my control. I’m also on Linkedin where you can easily connect with me.

So many Facebook friend requests..

Common!! How do i manage all these friend requests ?
Common!! How do I manage all these friend requests ?

However, I have gone through some profiles which is kinda weird. For example, let’s take a look at this friend request from one “Caroline Jane” who is apparently from New York and lives in United Kingdom. She is single too ^^.

 

Use images.google.com

I went on images.google.com and uploaded her profile picture there and made a search by image.

According to this simple research, she is a porn actress and her name is in fact Alina Li.

Now, you can use the same tool to check if your profile picture has been stolen and used in another profile picture. Share your comments if you have any ideas how to prevent Facebook friend requests flooding.


IETF 101 Hackathon by the Hackers.mu team

We believe in rough consensus and running code” – Just have a look at the IETF website, this is the motto that you would come across. This is why the IETF hackathons are so special during the year and hackers.mu team is proud to be the first team in Mauritius who does not only participate in such type of event but also lead the TLS working group. The IETF 101 hackathon was yet another challenge for the hackers.mu team. But, once you are in, the fun begins. Compared to the IETF 100 hackathon, hackers.mu team made an improvement in terms of lines of codes and focused on more projects. We participated remotely in projects such as TLS 1.3, DNS, and HTTP 451. A wiki was also created during that event.

We used Jabber to communicate for the IETF 101 hackathon. Other media such as Facebook was found out to be interesting. I should admit that on Friday and Saturday I went to sleep at 02.00 AM with just the testing part completed. At 23:00 hrs, Logan was asking everyone to go to sleep as we needed more energy on the next day. Selven was also working hard remotely to bring all members on track. What is more relieving is the team spirit where everyone was helping each other during that hackathon.

One of the interesting issues noticed is about TLS malformed traffic and such thing was able to be detected using Wireshark. Once the patches were ready and the testing part was working fine, we made a debrief at Flying Dodo beer brewing company at Bagatelle Mall and was ready submit patches to their respective projects. I was assigned the “Stunnel” project and a library in “Eclipse Paho”.

Debriefing at Flying Dodo accompanied with beer and some fries

After the debriefing, Logan was getting ready for his remote presentation at the IETF. We all went through the slides that logan created and went back home happily to see the presentation live on YouTube.

Special thanks goes to the IETF Organising team for having us as Technology Champions! Nick Sullivan head of cryptography expert at CloudFlare, Charkes Eckel, Barry Leiba, Meetecho team, Cisco for sponsoring the event and the all members of the hackers.mu team which made this hackathon a success in the world history of Mauritius.

Other’s are also talking about the IETF 101 hackathon ?

“I had initially started a bit slow, as I was working on other projects in parallel. Everyone was already deeply immersed in their projects, we could see PRs and code merges flying right from the first day.”Codarren Velvindron

“It seems that I am not the only one who feels that this hackathon was really addictive. we were hooked the moment we started working out on our tasks.”Pirabarlen Cheenaramen

Developers working with OpenSSL can finally start to work with TLS 1.3, thanks to the alpha version of OpenSSL 1.1.1 that landed yesterday.” – TheRegister

I think that you guys have more better weather and more fun that we did”Charles Eckel

The DNS madness: 185 RFCs totaling 2781 pages. Hello DNS security flaws ” – Loganaden Velvindron

hackers.mu pioneering the internet! We made it to IETF 101 hackathon with our team members getting featured in front of thousands, followed by a round of applause by IETF members in London. Congratulations guys, we did it again!”Yasir Auleear 

IETF Hackathons encourage developers to collaborate and develop utilities, ideas, sample code and solutions that show practical implementations of IETF standards. The IETF Hackathon in London on 17-18 March is poised to be the largest ever.” – IETF

 In case you are asking yourself, “who are the hackers.mu ?” You can consider is as “a group of developers from Mauritius who loves to code and are passionate about information security.” More information at https://www.hackers.mu


Happy New Year 2018 from TheTunnelix

My dear friends, readers and fellow bloggers, I would like to seize this opportunity as this is my last blog for the year 2017 to wish you and your family a Happy New Year 2018. There were lots of events in the month of November – December 2017. For today, I’m having a drink with family and friends. Oh yeah, Tomorrow, will be a super party 🙂

Those who missed hackers.mu events recently, in the month of November was about the Infotech 2017 where hackers.mu was present on our special stand busy evangelising OpenSource products. Our accomplishments were also displayed. Logan, from the hackers.mu team also made an amazing speech at the video conference room.

The hackers.mu team also had an end of year get together and lunch in a restaurant at Rose-Hill.

I’m happy to be able to complete my VMware Certified Administrator and VMware Certified Administrator Professional exams. I’m looking forward for more certifications next year. This year has marked the history of Mauritius where lot’s of Open Source contributions were carried out from Mauritians, mainly by hackers.mu. Right now, we have several stuffs in our pipeline. Surprise soon 🙂


A trip to a Wind Farm at Plaine Des Roches

This Sunday the 16th of April, I came across an interesting location in the North-East at Plaine Des Roches, Mauritius where electricity is produced through Wind Farms. The company is Quadran which has invested in this environmental friendly interesting project. Quadran is the global actor in renewable energy encompassing hydroelectricity, solar energy, wind energy and biogas. It has 130 collaborators from 13 agencies and subsidiaries in France metropolitan and Outre-mer including Reunion Island.Quadran. 

The electricity is produced by means of kinetic energy from the wind. The wind turns the blades, which spin a shaft connected to a generator which makes electricity. At some moment, when there is not enough wind, a fuel-powered engine will use switch on automatically for some seconds to run the turbine after which, the wind will take over to turn the blades.

I believe that Mauritius which is looking forward for a more eco-friendly island should invest more in these type of project. This project which involves 11 wind turbines with a power production of 9, 35 MW will satisfy the energy consumption of approximately 10,150 people.

However, side effects of wind turbines are not false. According to some source, there are also reports of negative effects on radio and television reception in wind farm communities. Potential solutions include predictive interference modeling as a component of site selection. A 2007 report by the U.S. National Research Council noted that noise produced by wind turbines is generally not a major concern for humans beyond a half-mile or so. Low-frequency vibration and its effects on humans are not well understood and sensitivity to such vibration resulting from wind-turbine noise is highly variable among humans. – www.nap.edu
