Rootconf 2016

Rootconf is India's principal conference where systems and operations engineers share real world knowledge about building resilient and scalable systems.

Rootconf is India’s principal conference where systems and operations engineers share real world knowledge about building resilient and scalable systems.

We are now accepting submissions for our next edition which will take place in Bangalore 14-15 April 2016.


The theme for this edition will be learning from failure. We are keen to explore how devops think about failure when designing, building and scaling their systems. We invite presentations related to failure in database systems, servers and network infrastructure.

We encourage presentations that relate to failure not only in terms of avoidance but also in terms of mitigation and education. How do we decide which parts of our systems cannot fail? What measures do we take to mitigate failure when it does inevitably happen? And most importantly: what lessons can be learned from failure?

Format #

This year’s edition spans two days of hands-on workshops and conference. We are inviting proposals for:

  • Full-length 40 minute talks.
  • Crisp 15-minute talks.
  • Sponsored sessions, 15 minute duration (limited slots available; subject to editorial scrutiny and approval).
  • Hands-on Workshop sessions, 3 and 6 hour duration.

Selection process #

Proposals will be filtered and shortlisted by an Editorial Panel. We urge you to add links to videos / slide decks when submitting proposals. This will help us understand your past speaking experience. Blurbs or blog posts covering the relevance of a particular problem statement and how it is tackled will help the Editorial Panel better judge your proposals.

We expect you to submit an outline of your proposed talk – either in the form of a mind map or a text document or draft slides within two weeks of submitting your proposal.

We will notify you about the status of your proposal within three weeks of submission.

Selected speakers must participate in one-two rounds of rehearsals before the conference. This is mandatory and helps you to prepare well for the conference.

There is only one speaker per session. Entry is free for selected speakers. As our budget is limited, we will prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. HasGeek will provide a grant to cover part of your travel and accommodation in Bangalore. Grants are limited and made available to speakers delivering full sessions (40 minutes or longer).

Commitment to open source #

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like it to be available under a permissive open source licence. If your software is commercially licensed or available under a combination of commercial and restrictive open source licences (such as the various forms of the GPL), please consider picking up a sponsorship. We recognise that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.

Key dates and deadlines #

  • Paper submission deadline: 31 January 2016
  • Schedule announcement: 29 February 2016
  • Conference dates: 14-15 April 2016

Rootconf will be held at the MLR Convention Centre, J P Nagar.

Learn to use the Tinc VPN, and, more imprortantly, learn why it’s a good thing to use, which is “A secure way to do insecure things.”

Outline #

In the past, the network was a safer place. The difference between a workstation and a server was a bit more vague. Desktops had apache web servers and NFS mounts coming from them. Workstations could run finger and connect to other hosts on the network. Printers were available to anyone who could broadcast onto the network. Video was shipped across the network to random hosts or multicast addresses. Security wasn’t something we worried about because we trusted everyone on the network.

I personally never lived in this time, but I can imagine it being great. The early network was energized by awesome protocols for file sharing, video, communication, and peripherals. What I did experience was the last hoorah of this kind of ‘open’ network during my time at University.

My friends and I have deployed a peer-to-peer mesh network using Tinc ( This technology allows us to build an overlay network on the public internet that looks like a flat layer 3 network. Tinc networks are encrypted using SSL. Since we (mostly)trust everyone on the network, and all communication is encrypted, we can do things with our network that we’ve not been able to do before.

Given a secure way to do insecure things, a number of protocols that had been left in the wastebucket are back in play. NFS, UPnP, 515(print spooler), 79(finger) and more can be used securely in this network. This means our computers can behave more like the workstations of old, and we can live that glorious unix workstation heyday.

In addition, our laptops now have permanent IP addresses that have transparent encryption to other nodes on the network. This opens the door for all kinds of cool automation and tricks, that will be shown in this talk. This quickly became a service discovery problem and we deployed Consul ( to detect service availability and to provide name services into the network.

Requirements #

Eyes, ears, and a laptop if you want to follow along.
