Ninux in CONFINE

Tuesday, April 29th, 2014


English version below.

Chi fa ricerca nel mondo delle reti si ritrova quasi sempre a fare esperimenti simulati al calcolatore o in laboratorio, visto che le reti reali, con utenti veri, di solito non sono accessibili.

Per questo motivo è nato il progetto CONFINE, che ha l’obiettivo di costruire un’infrastruttura all’interno di varie community network europee, da sempre propense alla sperimentazione, per metterla a disposizione dei ricercatori.

A Guifi, AWMN e Funkfeuer si è ora aggiunta la community Ninux!

L’idea fondamentale di CONFINE è quella di distribuire all’interno delle community network dei piccoli computer, detti research device, da collegare ai nodi. Sui research device gira un sistema operativo basato su OpenWrt in grado di preparare e mettere a disposizione macchine virtuali, su richiesta di un controller centrale. I ricercatori hanno a disposizione un’interfaccia web per richiedere macchine virtuali poi accessibili tramite SSH dentro una VPN.

Aiutati da CNIT dell’università di Roma Tor Vergata e da Unidata, che da sempre supportano la nostra community, verranno distribuiti ed installati research device dentro la rete Ninux. L’hardware principale che useremo sono Intel NUC, dotati di processori i3, 4GB di RAM e 60 GB di hard disk allo stato solido. I consumi variano tra gli 8 Watt in idle e i 20 Watt a pieno regime, la temperatura misurata sul case non supera mai i 40 gradi e sono dotati di una ventola quasi impercettibile.

Poi, in una seconda fase, il sistema operativo dei research device verrà modificato per permettere ai ricercatori di effettuare esperimenti basati su OpenFlow. L’abstract completo del progetto, con altri dettagli, si trova sul wiki.

In più, le macchine virtuali potranno essere utilizzate dai membri di Ninux per servizi distribuiti e replicati all’interno della community network, dando vita, di fatto, ad un embrione di cloud comunitaria.

English Version

Network researchers usually find themselves experimenting through simulations or artificial infrastructures built in laboratories, because usually real world networks, with real users, are not accessible to them.

For this reason the CONFINE project was born, aiming at building an infrastructure inside European community networks, which have been prone to experimentation since always, to make it available to researchers.

After Guifi, AWMN and Funkfeuer, also Ninux has joined CONFINE!

The main idea of the project is to spread small computers, called research devices, inside community networks, to be connected to nodes. Research devices run an operating system based on OpenWrt, which can provide virtual machines when requested by a central controller. Researchers can allocate virtual machines through a Web interface which can be later accessed through SSH over a VPN.

Helped by CNIT of the University of Rome Tor Vergata and by Unidata, which since always support our community, research devices will be deployed inside the Ninux network. The hardware that we will mainly use are Intel NUCs, with i3 CPUs, 4GB RAM, 60GB SSD drive. Measured power goes from 8 Watt when idle to 20 Watt at full capacity, the temperature on the case is always below 40 degrees celsius and the fan onboard is almost unhearable.

Then, at a second stage, the operating system on research devices will be modified to allow researchers to perform OpenFlow based experiments. The complete abstract of the project, with further details, can be found on the wiki.

Also, the virtual machines may be used by Ninux members for distributed and replicated services inside the community network, sowing the seeds of a community cloud.

Ninux Day 2009 Report

Wednesday, December 9th, 2009

I’m so sorry I was totally busy and I hadn’t time yet to blog about the Ninux Day !!! So it is now time to write something !

It was our first Ninux Day, and it was great !

Every started Thursday night. Many of our international guests were already here in Rome, so we had a Warm up Party at Fusolab.

The following morning I went to Defrag_ to open up the place around 10.00, because the first people were expected by 12.00. Thanks to Andrea we had some beautiful posters at the entrance, as you can see in the picture.


Friday was quite a busy day. We had  many interesting talks, and people started to know each other. Only on the first day we had more than 50 people attending, and many were coming from abroad. On Sunday we had registered 123 people !

The first talk started a bit late, Ulf was the first one to have his slides ready, so I sent him on stage :) He started an interesting talk on how to manage cameras with embedded devices running OpenWRT and gphoto. The goal was to use the embedded devices to make panoramic pictures. Friday talks were on many different topics. After Ulf we had Alexander List talking about the Open Spectrum. After a while the “use the wiki” signs we had put everywhere at Defrag_ started to work… the hackers were self managing the event their self, timetable was optimized, talks were shaped to the avaiable timeslots… it is always cool to see how the hacker society can self manage an event :)


To help the people know each other we organized a permanent PGP Signing Party. Most of us exchange emails during the year, very often attaching patches and snippets of code. It is a good thing to make sure about the identity of the person who is writing to you. So the key signing had begin ! After a while people were interacting together, coding, discussing about protocol, showing their work to others.


The long Ninux Day continued for the all weekend until Sunday in the late afternoon. For the first time I have seen people from wireless communities from all Europe actually working together and exchanging ideas. I was very very happy about the result, even if organizing everything I missed many details on the presentation and works that were going on ! But it was ok! I just can’t do too many things at the same time :)

The very good thing about this event is that now people are still discussing and working on the ideas and projects developed in the weekend in Rome. On the Ninux Day mailing list and on the nodedb-interop list you will find community members from all europe actively working.

Well, it is too had to describe the Ninux Day in such a short blog post, so if this year you have missed it, I suggest it is much better to come next year and see with your eyes !

Happy hacking !
