Africa Internet Summit 2018 – My first day in Dakar Senegal – Day 0

Dakar offers much to see and do, but my goal this trip lies elsewhere: facilitating the #AISdakar 2018 NTP – Network Time Protocol hackathon under the banner of hackers.mu which has been planned days back at Radisson blu hotel. Network Time Protocol (NTP) packets, as specified by RFC 5905 [RFC5905], carry a great deal of information about the state of the NTP daemon which transmitted them. In the case of mode 4 packets (responses sent from server to client), as well as in broadcast (mode 5) and symmetric peering modes (mode 1/2), most of this information is essential for accurate and reliable time synchronizaton. However, in mode 3 packets (requests sent from client to server), most of these fields serve no purpose. Server implementations never need to inspect them, and they can achieve nothing by doing so. Populating these fields with accurate information is harmful to privacy of clients because it allows a passive observer to fingerprint clients and track them as they move across networks.

The trip from Mauritius to Senegal was lengthy but at the same time, I got to discover parts of Africa: from South Africa to Kenya, hitting Ivory Coast before reaching Dakar, Senegal. During our transit in Johannesburg, Logan and I discussed several aspects of the AIS hackathon 2018 over two large pizzas and beers. One of the main goal is to maintain clear and precise billingual communication in English and French. Our next objective was to make sure that the required level should be reached for the hackathon.

I did not know that the plane will land at Ivory Coast before heading towards Dakar. Gazing out of the plane offered us unique breath taking and impressive views of infrastructures, panorama of the land and landscapes.

 

Disembarking at Dakar International Airport, I was received by the driver who works for a well reputed company – Prestige. Logan was received by an other company. Whilst travelling to the hotel, that guy was displaying curiosity and was inquisitive about computer repairs. I gave him some tips such as YouTube tutorials and some helpful links.

After landing, I headed directly to and checked in Novotel Hotel in Dakar where I checked in. I received a warm welcome staff members. Tired after long hours of travelling, a nap was very much needed before anything else. The view from the hotel room was magnificent with a swimming pool and beach nearside.

 

By the time I woke up, it was already late at about 21:00 hrs, I went to Radisson blu and met Kevin Chege and other delegates at the Gala Dinner. The atmosphere was friendly, welcoming and promising.

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

The cyberstorm.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 cyberstorm.mu. Right now, we have several stuffs in our pipeline. Surprise soon 🙂


IT and Internet Users of Dodoland by cyberstorm.mu

Since the split of the Linux community in Mauritius, cyberstorm.mu (name rebranded due to trademark issues) was born. A new vision and objectives were the foundation of the cyberstorm.mu group. Our aim is to reach more people who will code in software that are used worldwide. The cyberstorm.mu family kept growing. Today, we have brought more members to the cyberstorm.mu community and right now, there is a boom in this group. Additionally, people from various part of the world wants to be part of the group, as seen on our Facebook group. cyberstorm.mu has been hosting live video streams on YouTube to bring together more people willing to learn and share in the community.

Just chill. Let me get back to the title of this blog – IT and Internet Users of Dodoland! On Saturday, the 18th of November 2017, I was at the University of Mauritius together with Logan. We were joined by Jagveer Loky. A presentation was carried out on “Introduction to Github” and the launch of the Mailing List called the “IT and Internet Users of Dodoland”. During the presentation, Logan brushed over the importance of having a Github account as well as sharing one’s code on it.

An example is to publish one’s assignment by a student. This acts as a catalyst for the academic development of the student. Today, companies will usually search the Github account of people, including Mauritians before recruiting them. Students were encouraged to create their Github accounts and even a blog. Then, we discussed about the achievement in the IETF 100 Hackathon. For example, the patches about TLS 1.3 during the IETF 100 Hackathon. At the end of the session, we announced the creation of the Mailing List “IT and Internet Users of Dodoland”. Jagveer Loky from the cyberstorm.mu community was chosen to be the moderator of the mailing list. He will ensure the proper and smooth running of the mailing list.

At the University of Mauritius

At the end of the presentation, we had conversations with the students who were interested in topics such as OpenSSH, MVC, Java Programming, and MongoDB. Notes were taken to focus on these topics in the days to come. Then, we headed to Flying Dodo Bagatelle to celebrate the launch of the new mailing list by the cyberstorm.mu team.

We also had a video stream, where we were joined by other people from the cyberstorm.mu community who came forward asking questions about the IETF 100 Hackathon and on several aspects of TLS1.3. Jagveer shoot a question as to whether people knew about the IETF in Mauritius. Of course, many knows about the IETF, but at what level is the contribution? As a technical guy, merely watching what’s going on at an IETF Hackathon does not make sense but instead contributions should be carried out in terms of codes to make the OpenSource community more rigid.

At cyberstorm.mu, we kept on innovating to transmit the messages through the internet as well as on the ground. Weeks back, we were also at the University of Mauritius where we met Yashtir Gopee who is a passionate of robotics and Artificial Intelligence. He also joined the cyberstorm.mu community and is willing to join the “IT and Internet Users of Dodoland” Mailing List.

Yashtir and Logan

Indeed, we have come a long way since the creation of cyberstorm.mu. In such short time, we have been able to meet our objectives and we are continuing towards innovations and quality work in the group. I am looking forward that people make good use of the Mailing List and bring forward their issues as well as their contributions. Click to join the Mailing list.


IETF 100 hackathon on TLS 1.3 by cyberstorm.mu

Some days back, The Register mentioned cyberstorm.mu (name rebranded due to trademark issues) preparing for IETF100 hackathon. Hooray! Yeah, we did it and the hard work finally paid off thanks to the core team and the whole of cyberstorm.mu team. After registering on the IETF – Internet Engineering Task Force website, the cyberstorm.mu team set itself on the TLS1.3 API source code. We were all focused on the OpenSSL codes.

Once in our office, we set up the network and our equipment. Check out logan’s blog to have an idea how things went on. That’s true we struggled in the beginning, but finally we could see the light at the end of the tunnel. Patience and patience is all what you need and a calm mind to study how things are in the code. The testing was then carried out to confirm the beauty of the TLS 1.3 codes in our chosen projects. You can also view the TLS tutorial which explains the objectives of TLS1.3. For example: Mitigation of pervasive monitoring.

Here are some hints about the security from TLS1.3

  • RSA key was removed.
  • Stream ciphers was reviewed.
  • Removal of compressed data mechanism which was able to influence which data can be sent.
  • Renegotiation was removed.
  • SHA1 and Block ciphers were removed.
  • Use of modern cryptography like A-EAD.
  • Use of modern key such as PSK.

For more details see this blog from OpenSSL. We were also working together with the TLS team in Singapore which was lead by Nick Sullivan, champion at the IETF TLS hackathon.

After the IETF Hackathon, it was announced publicly about the good job done by the cyberstorm.mu team on the IETF channel.

cyberstorm.mu VideoStream #2 : Modem Insecurity in Mauritius

Some days back, the cyberstorm.mu (Name rebranded due to trademark issue) team made our first video stream on Youtube about Modem Insecurity in Mauritius. We received several feedbacks from the public, friends and local media about the issue raised. Upon further research, I noticed that there are several countries including Vietnam, China amongst others are in the same problematic situation as they are using the same Huawei modem. More and more vulnerabilities are now being faced by the end users. Users aware of the issue can mitigate it from their side whilst others are still in the dark.

 

On Friday, the 20th of October 2017, another video stream was carried out by the cyberstorm.mu alongside other friends and professionals. We started with a short introduction from everybody in the videostream.

We had Billal, Codarren, Edriss, Irshaad, Logan, Kifah, Selven, Rahul, Yash and myself (Nitin) participating in the video stream. You can view the VideoStream here:

Our agenda was as follows:

  • An introduction from participants
  • Huawei’s acceptance of upgrading Dnsmasq
  • Other discoveries in the Huawei modem
  • The implication of Krack attack
  • Understanding the mitigation techniques on Krack attack
  • Everyone’s perspective about the vulnerabilities on the Huawei modem
