Africa Internet Summit 2018 – Hackathon – Day 2 & 3

06/17/2018 Nitin J Mutkawoa Add Comment

Back to blogging after some days, I still recalled the moments in Dakar, Senegal for the Africa Internet Summit. By the time, so many days already elapsed, many have already blogged about the event and more pictures raining on the social media. Our camera, tripod, and laptops were all ready. In case, you have missed Day 0 and Day 1, feel free to click on the links.

On day 2, myself with Logan and Serge made a brief introduction of the Network Time Protocol. Serge explained about the TCPDump and Wireshark tools that we can use to understand NTP traffic. We also made some demo about the NTP packets exchange between the client and the server. The algorithm behind was made clear, brief and concise as without which the hacking part would be difficult. Participants chose their projects for the hackathon. Some registered themselves for the Network Programmability track and the Intelligent Transportation Systems Projects. At the end of the day 2 we were already convinced about the hackathon would be a success. Myself, Logan and Charles decided to have a beer at a nearby restaurant.

Day 3 was the moment where everyone looked forward to hack into the code. The team spirit was here. Everyone was helping each other in their ‘parcours’. For the NTP hackathon, more and more participants start joining the team. Additional chairs and tables were needed. The best idea was to form into groups and this is where things change for the good. Patches start raining. Several tests were also carried out to confirm the code was running.

At the end of the hackathon, each group went to present their project and achievements. Their presentation slides can be viewed on the AIS wiki.

Some interesting links:

- More information about the NTP hackathon is already uploaded on the AIS wiki.

- The meeting statistics and report can be viewed here.

- There is also a blog coverage by Charles from CISCO.

- Dawit Bekele speech at the African Internet Summit 2019.

Another Interesting article by Kevin Chege from Internet Society.

Africa Internet Summit 2018 – Getting ready for the Hackathon – Day 1

05/15/2018 Nitin J Mutkawoa Add Comment

On day 1, I woke up early in the morning and went outside for a morning walk. Everyone in Senegal says Bonjour to each other, irrespective of being a stranger. The people of Dakar seem very polite and relaxed in nature. Whilst walking on the coastal road of Novotel, I admired the beauty of several massive Baobab trees.

Back at the hotel, the breakfast was delicious with lots of fruits and cakes accompanied with juice. By the time, breakfast was over, it was already 0800 AM. I took a Panoramic view from the back of Novotel.

I had to get ready as I needed to travel from Novotel hotel to Radisson Blu where the hackathon preparation was going on. I met with Serge-Parfait GOMA instructor at the Hackathon together with Loganaden Velvindron from Afrinic. On Day 1, there were about 15 participants who already registered themselves. We had to prepare for the Hackathon as it needed to be carried out both in English and French.

Preparing for the Hackathon demands lots of time and trying to cover the maximum: from the basics until when the code need to be hacked. The project chosen was the NTP client. I created both slides in English and French.

Whilst I was preparing for the slides, Serge was busy setting up the Pidgin channel. We also tested the livestream. I brought a tripod for my Iphone 7 as it’s so easy for live YouTube video broadcast. We also checked out the hackathon room and carried out several tests. We were happy to be assisted by the guys from ISOC who were always there to help. We reviewed the code anew and discussed a little about the RFCs and Internet Drafts for that specific hackathon.

Time for dinner where I met fellows from Afrinic such as Duksh Koonjoobeeharry from Atlassian User group of Mauritius and Afrinic, Mukom Akong Tamon from Afrinic – That guy is an IPv6 ninja, Charles Eckel from CISCO who was also leading the hackathon on the network programmability track. I also met other persons from the ISOC team and Nishal Goburdhan a FreeBSD evangelist who gave me a FreeBSD sticker.

By the time, dinner was over, it was already late. I went to meet the ISOC and Afrinic guys who were still working hard to set up the hackathon room. I took a cab and headed directly to Novotel hotel.

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

05/08/2018 Nitin J Mutkawoa Add Comment

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 cyberstorm.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.

ISOC IETF session & Side conference at AFRINIC-25

12/01/2016 Nitin J Mutkawoa Add Comment

AFRINIC-25 was held at Sofitel Imperial Resort & Spa in Mauritius this year from 25th to 30th of November 2016. Members of cyberstorm.mu were proud to be present during the ISOC IETF session. Logan, who is also a member of cyberstorm.mu introduced me to Kevin G. Chege of ISOC who was leading the meeting. There were several topics tossed on technical IETF standards at the workplace by Padma Pillay-Esnault of Huawei.

I made a short introduction on OpenSUSE as an OpenSUSE advocate and laid emphasis on the challenges of the OpenSUSE community in terms of code contribution. Also, a brief overview of the OpenSUSE infrastructure, the open build service, the visualization platform, and factory development at OpenSUSE.

One of the contributions made during the cyberstorm.mu hackathon – Operation SAD – Search and Destroy where codes were contributed to Monit – An opensource utility for proactive monitoring. It can conduct automatic maintenance and repair. What is most interesting during the hackathon is the deprecation of SSLv3 in Monit.

More details were shed on the spreading of the disease called SSLv3. There are many developers still importing Monit as secondary tools on their application. A live example where Github repos are infected with SSLv3 where the same need to be removed to mitigate attacks. The RFC 7568 (Thanks to the TLS working group) – which was applied during the course of the hackathon was taken as an example as well as the methodology and application of the SDLC – Software Development Life Cycle standards during the hackathon.

A slide during the IETF meeting

An open discussion among participants and audience was then carried out. The aim is to have each one to share their concerns and initiative to reach their goals. As regards to me, i laid emphasis that IETF materials should not only reach University students, but also other individuals who have the skills and know-how and ready to learn for the betterment of Africa and Mauritius. Hackathons were proposed to be carried out at international level under the umbrella of the IETF – Internet Engineering Task Force.

I would also sincerely thank the ISOC, AFRINIC and sponsors for making this event a successful one.
