Today is the first day for the IETF 103 remote hackathon in Mauritius. The cyberstorm.mu team is ready to lead and participate in all the three tracks as champions for the event. We have the TLS 1.3, SSH and HTTP 451. All the three tracks are lead by cyberstorm.mu as champions.
Our first timers for the IETF 103 hackathon is Kheshav Sewnundun, creator of XpressLiteCoin.com and Devops Engineer at Linkbynet Indian Ocean. We also have Diresh Soomirtee, Junior system administrator at Linkbynet Indian Ocean.
Prior before the hackathon, we did some shopping for the basic amenities. We reached at the quarter at a Mauritius Villas, a bungalow in Pointe Aux Piments at around 13:00 hrs. The network was set up with two different ISPs in case of breakdown, we can still be live during the hackathon.
We also celebrated Kifah’s birthday during the hackathon.
At cyberstorm.mu, it’s always the pool that brings more relaxing time. We are also in the Halloween week and some guys even brought their Halloween costumes and went swimming inside the pool.
Most of us already started working on our projects and some pull requests already sent. More testing on progress as well as creating of several patches. We even need to have a discussion on open source licensing to make sure that there are incompatibility issues between different licenses. We made a plan for the three tracks we are championing and it looks to start pretty fine.
By this time, it’s already late here. I really need some sleep to start day 1 for the IETF 103 hackathon 🙂
I should say that we were already planning about our next event, hence, a hackathon on Operation KSK-ROLL by the cyberstorm.mu team which was pretty easy, important and successful. Dr. Till Jaeger congratulate us for creating the cyberstorm.mu team. Several pull requests sent to many repositories to encourage developers to adopt the new key.
What is Operation KSK-ROLL?
At cyberstorm.mu all Non-IETF hackathons are usually given a name. This time for the KSK rollover hackathon we have chosen 'Operation KSK-Roll'. Operation KSK-ROLL has been started to make sure that software is up-to-date with the new KSK key.
What is the KSK rollover?
The DNS KSK Rollover happened on 11 October at 11:00 UTC. Rolling the KSK means generating a new key cryptographic key pair (public and private key).
What are those keys?
The public key is distributed to those who operate valid DNS resolvers such as ISPs, network administrators, system integrators etc.. whilst, the private key is kept secret.
If its secret, why do we need to generate another secret key?
For security purpose, the secret key is generated anew and this ensures that DNS resolvers have a more robust security layer on top of the DNS AKA: DNSSEC
What are DNS resolvers?
All websites, example tunnelix.com which is a domain name is behind an IP Address. For your browser to be able to resolve the website, a DNS resolver which is located at several parts of the world will identify the IP with the domain name. Consequently, this will render the website on your browser.
What is DNSSEC?
As mentioned previously, DNSSEC (DNS Security) is a layer added by ICANN to ensure by means of cryptographic keys to ensure an online protection from the provider of the root domain name to your browser.
How will you know if a website is DNSSEC signed?
There is a tool by VeriSign lab which provides DNSSEC Analyzer. You can enter the name of the domain, say tunnelix.com which will analyze the domain show you the public key and the chain from the . (dot), com and tunnelix.com.
Is there another way to verify it?
Yes, you can use the nslookup or dig tool to check it. In the case of the dig tool here is a screenshot.
What is the logic behind the DIG command?
Some years back (the Year 2015), I explained the anatomy of the dig command. You can view more details about the blog post called "Anatomy of a simple dig result".
What is the role of the KSK?
The KSK private key is used to generate a digital signature for the ZSK. In fact, the KSK public key is stored in the DNS to be used for authenticating the ZSK. So, the KSK is a key to sign another key for the ZSK. That is why it is called the "Key Signing Key".
So, what is the ZSK?
The ZSK (Zone Signing Key) is another private-public key pair which is used to generate a digital signature known as RRSIG ( Resource Record Signature). The RRSIG in itself is a digital signature for each RRSET (Resource Record Sets) in a zone. In fact, the ZSK is stored in the domain name system to authenticate the RRset.
What are RRsets?
RRsets (Resource Record sets) is a group of records DNS Record Set (RRsets) with the same record type, for example, all DNS A records are one RRset.
My contributions for KSK ROLL
Please follow me on my Github account. One of the repositories is Nagval which is a plugin to check the validity of one of more DNSSEC domains.
For more information about DNSSEC, ZSK, PSK etc, I would advise to check out Cloudflare which provided a good source of information.
Cyberstorm.mu continue to go beyond and further with innovations and more ideas to protect and secure the Internet. We believe that though we are a small team will be able to recruit more people who are strongly interested in developing their skills to strive for excellence.
I also wish to seize this opportunity to thanks Manuv Panchoo for designing the logo of tunnelix.com

Some pictures during the informal event:
OpenSource licensing with Dr. Till Jaeger and cyberstorm.mu
I should admit that it was really an informal meeting over some beers, juice, Dame-Blanche, and Pizzas with Dr. Till Jaeger. It was very fruitful and amazing to the team. We received lots of advice for ourselves as well as for the cyberstorm.mu team. Some days back, the National Computer Board conducted a workshop on Opensource licensing which where Dr. Till Jaeger was the main resource person to deliver this workshop. Thanks to the National Computer Board for making this event a success. Cyberstorm.mu members were also invited to the event.
We have also welcomed Rahul Golam for joining cyberstorm.mu team and looking forward to work together. I seized this opportunity to announce that cyberstorm.mu is proud to announce it’s official logo. Thanks to the hard work of the team.
We are for free and opensource software. We are presenting Mauritius worldwide in the IT sector. We are a Linux and Open source group which is going further and beyond. We believe in collaborative work and team spirit. We believed in running codes. We strived for excellence. We have contributed codes in several popular applications. We have worked on Internet-Drafts. We participate heavily in Hackathons.
The next step of cyberstorm.mu is championing several tracks for the IETF 103 hackathon remotely at Bangkok, Thailand. We have been welcomed by many people both from Mauritius and overseas, even from Silicon Valley, USA. No wonder, our past achievements is now a new step to reach today’s objectives – To focus heavily on research and development. Loganaden Velvindron from cyberstorm.mu mentioned on his Medium blog about the change cyberstorm.mu want to achieve: “The namecyberstorm.mu is an interesting one. It’s about change coming. Don’t get me wrong: I still love hacking. For me, hacking is about finding clever solutions to problems.” The youngest guy from the team is also going to participate in the IETF 103 hackathon.
The cyberstorm.mu team has been participating in several IETF hackathons these recent years. For the IETF 102 hackathon, we focused tremendously on innovation: The goal to create two teams for the TLS 1.3 project, one for the Implementation team and the other is Interop. At the same time, getting hands on the HTTP 451 project. The IETF hackathon encourages developers to collaborate and develop utilities, ideas, sample code and solutions that show practical implementations of IETF standards. It is not a competition but a collaborative event.
For this IETF hackathon, myself and Loganaden Velvindron core members of cyberstorm.mu team decided to lead the event. We searched a marvelous venue at Pointe aux Piments, a remote coastal area in the north-west of Mauritius which was very peaceful and can accommodate the whole team including first-timers of the IETF hackathon for three nights. As regards food, the best place is at Triolet, a village nearby which is famous for street foods including Pizza, Indian food, Grilled, Burgers and Brianis. We also chose that venue as it included a WiFi hotspot, several rooms, bathrooms and even a swimming pool.
On day 1, we all set up our lab environments and since most first-timers were in the TLS 1.3 Interoperability team, a plan was already designed. We knew since the beginning that there would be the logistic issues, so we brought spare laptops, screens, memory card, projector, etc.. Logan explained the situation we had to deal with especially when it comes to interoperability to the first-timers. Then, they assigned themselves some tasks. At first, it was time-consuming to get started, but at the end of day1, I can feel how everyone was working as a team and looking in the same direction for the TLS 1.3. On the other hand, Veegish was getting hands-on HTTP 451. Whilst the Interoperability team was having fun, the implementation team, on the other hand, was yet another challenge: Improving source code for TLS 1.3 compat layer.
On day 2, everyone woke up early and went for a morning walk. Afterward, the team was back to coding and debugging. Whilst some were on the implementation and Interoperability tasks, Veegish already advanced on the HTTP 451 project. A debrief carried out by logan to understand where the team stands. We had to constantly evaluate ourselves so that we knew in which direction we are moving. At the end of the day, most of us were already in the pool for some chilling moments. I seized the opportunity to make a Time Lapse video with my iPhone 7+ 🙂
On day 3, the atmosphere was intense. The implementation team needs to make sure the code has been tested and it is running correctly. I was heavily involved in the PHP CURL library part. The testing part was very challenging. At some moment I was so tired and hopeless as the testing part was really complex. At the same time, others were trying to help each other. Kifah was also on some bash scripting for the interoperability part. He wanted to automate some tasks. Logan was also looking at his code and helping the others. Well, at the end of the day we were so happy to be able to accomplish what we had planned. Everyone looked so tired. The only option is to go back to the pool.
We also decided to make some mini videoS to relate our experience during the hackathon. I uploaded the videos on YouTube. You can view it from the playlist below:
On day 4, we packed up to our destination. At that very moment in Montreal, the hackathon was still going on. I reached home at about 19:00 hrs Mauritius time. I was assigned a three minutes presentation for the hackathon carried out by the Mauritius team. It was already midnight. I was so tired. I knew that the presentation had to be carried out. Logan was constantly texting me to make sure that I did not fall asleep. You can view the presentation remotely live in Montreal Canada.
What did IETF hackers say about the IETF 102 hackathon?
“What I think was the most productive output during this time for me was pair-programming…”– Kifah
“I was very excited to be part of the Inter-operability team where I worked with OpenSSL, BoringSSL, WolfSSL, and tlslite using TLS1.3 protocols.”– Jagveer
“Making Internet Protocols great again during the IETF 102 hackathon” – Logan
“Finally after long hours of debugging he managed to test the protocol being used by NRPE locally”– Rahul
“Then… we finally got a Client Hello from Wireshark and made the PR”– Nigel
“At first I thought that it would only be working, working and working but besides of work we started creating bonds.” – Jeremie
“I got a lot of advice, support, and motivation to work with my team members and try to implement on a strategic basis and critical thinking the internet protocols and see their limit on a technical perspective.” – Avishai
“Once OpenSSL was installed, I then performed my first TLS 1.3 Handshake, Resumption, and 0-RTT but did run into difficulties with NSS.”– Chromico

We also had a follower on Twitter appreciating our effort and participation during the IETF 102 hackathon. Thanks, Dan York, senior manager at ISOC.
I’m happy that this hackathon was at the required level. It was a great initiative from the cyberstorm.mu team. No major incidents occurred in our HQ at Pointe aux Piments. Everything that was planned went all and it’s worth investing yourself in this collaborative event.
