Einladung zum Freien Freifunktreffen in Halle am 19.07.2014 (Sommerfest)

Wie jedes Jahr, trifft sich auch dieses Jahr die hallesche Freifunk-Community im Sommer am Hufeisensee. Es ist ein regionales Treffen, welches offen für alle Freifunk-Communitys ist. Hiermit möchten wir euch einladen am 19.07.2014 vorbei zu schauen.

Diesmal sind wir zu Gast auf dem Vereinsgelände vom Tauchclub Orca in der Schkeuditzer Str. 70 | 06116 Halle, wo wir uns ab 15 Uhr treffen. Das Gelände bietet alles, was Freifunker für ein produktives Treffen benötigen: Freifunk, Internet, Strom und Grill sind genauso vorhanden, wie Tische und Stühle um eigene Rechentechnik aufzubauen. Die Freifunk Community aus Halle will dieses Treffen nutzen, um einen eigenen Förderverein zu gründen. Der Förderverein soll die Aufgabe übernehmen, das Projekt Freifunk in Halle organisatorisch zu unterstützen. Weitere Informationen gibt es im Freifunk.net-Wiki. Fragen und Anregungen können auch bei uns im Forum diskutiert werden. Gäste werden gebeten, sich anzumelden, um besser planen zu können.

 

GSoC 2014: Hardware Detection

Hi everyone!

Before  starting coding I have been studying Lua programming language I read  some tutorials and I did some practical examples. After that, I went to  the Libre-Mesh architecture to understand better how it is done. When I  understood the programming pattern of LiMe I started coding.

First of all, I started creating a plug-in module for ath9k-htc based hardware. This module has been tested using a TP-LINK WDR3600 and two TL-WN722N USB radios. While working I have included an hotplug hook so the usb radios can be dynamically plugged and removed from the system while it's running. 

After  having the usbradio module almost done I have been working creating a  modular hardware detection plug-in for Libre-Mesh. This hardware  detection module have been completed with clean and configure functions. During the development of this part I have discovered some bugs in the file config.lua and I have solved it.

Currently, after doing some cleaning and debugging both modules are almost finished.

Obviously  all this work have been possible thank to the help of the community and  I hope to do my best during the rest of the coding period.

I will be happy to receive feedback or tips

Best Regards ;)

Free Community Networks in Catalonia with Guifi.net

Ramon Roca from Guifi.net talking to ARTE-TV.

Thanks to Elektra for the translation.

Gurb in Spain
1002 km to Brussels

Ramon: The NSA scandal almost makes us laugh I have founded Guifi.net so we can build broadband internet access ourselves.

Voiceover: Here in the middle of the catalan nowhere a digital revolution started 10 years ago.

Ramon and his neighbors have build their own broadband internet because the big commercial providers had no interest in providing access to the village and its vicinity. Today, Guifi.net is one of the greatest altenative networks in the world.

Ramon: I want to show you where the cables merge together. Right here. This rack is the equivalent of a telephone switchboard in a village. It is a bit dirty because this shag actually belongs to my garden. What it can do is impressing. I can't say it precisely, but these are the routers of 5000 households.

Overdub: In a Freifunk-Network the participants are networking among each other and not via Internet providers. They can directly share data with each other, chat, write e-mails. A decentralized network that the users control themselves.
Thereby their data is secured from access by third parties. Meanwhile, the Internet-Guerilla are able to roll out their own fiberline network. Today, Ramons colleagues are working since 3 AM. We all know that the government operates slowly.
We can't wait until laws are solving all our problems.

In our case this also comfortable for us: With regards to communication, we can do or not do whatever we like.

Freifunk Wireless Community Weekend 2014 at c-base Berlin, May 30 - June 1

Community mesh networkers from around the world are meeting in May 2014 at the c-base in Berlin.

There are Pre-Meetings May 28 and 29, the „official program“ starts 30th and last until June 1st. In fact the final version of the agenda will be created by attendents on-site. If you add your idea or wish to our wiki upfront, we can take care of your talk or workshop. Hacks sessions are taking place over the whole weekend.

This year we focus on topics like crypto, IPv6 and new services, but also like always latest firmware, new installation setups and last not least legal and political update plus public relations. Following the tradition we'll have barbecue in the evening hours at Spree beach and we don’t charge entry fee.

Your API file in only 6 steps

  1. Call up http://freifunk.net/api-generator/ 
  2. Fill in the information about your community in the form and press "OK - generate...". Mandatory fields are marked with an asterisk. The more information you enter, the better. 
  3. Your results will be displayed on the right hand side. If information is missing or fields are incorrectly filled, you will see it marked under the text box. Fill in or correct the information and generate the API file again.
  4. Save the content of the text box to a text file on your computer or press the download button. This puts a file with an encrypted file name in the default download directory of your browser. Unfortunately we cannot change that for technical reasons. 
  5. Upload the file created under point 4. to the Internet on to your Web space, in your content management system or our freifunk wiki. You will need a link to that file.
  6. The link must be added to the API directory. If you trust yourself, create a pull request, or you can send the link via contact form. If you chose the later, select "question about the API" as subject.

Please note: If you want to update, download or edit your API file, you can choose to do so after the entering the API directory, in the drop-down menu on the top right. The file must however be resaved or downloaded and uploaded to the Web server again.  

Please also use the possibilities to update information such as the number of nodes or services automatically and regularly. Gluon developers have written an examplary script, and there is a solution for OLSR-based networks on Github

You can find background information on the API in the blog and on freifunk.net.  

The most recent changes are summarized here.

Neues aus der API-Werkstatt

Nach einige Zeit hat es mal wieder einen Versionssprung bei der Freifunk-API gegeben: Unsere Freifunk-API steht ab sofort in Version 0.3.0 bereit. Bestehende API-Dateien sollten schnell aktualisiert werden, da sich einige nicht rückwärtskompatible Änderungen ergeben haben.

Neuerungen und Änderungen der Spezifikation

    • Services hinzugefügt, netz-interne Dienste können hier angegeben werden. Später soll aus diesen Daten eine freifunk-weite Serviceübersicht entstehen
    • Timeline hinzugefügt, hier können Communities wichtige Meilensteine ihrer Geschichte eintragen (z.B. Gründung, Neugründung, wichtige Ereignisse wie Vereingründung oder Rekordstände bei Nutzern/Routern). Mit diesen Daten können schöne Zeitstrahlen erstellt werden
    • TLD hinzugefügt, damit Communities die von ihnen genutzten Top Level Domains (.ffhh, ffl, ...) benennen können. Die Informationen können genutzt werden, um die DNS-Konfiguration über die eigene Community hinaus nutzen zu können
    • Kalender-Sektion entfernt, durch Feed vom Typ ics ersetzt. Eine eigene Kalenderspezifikation erwies sich als zu komplex. Mit ics-Files kann man leicht übergreifende Kalender erstellen 
  • Country als Feld aufgenommen
  • Pattern zur Validierung von Eingaben für diese Felder eingeführt: urls, irc, twitter, email, facebook, ip-Adressen
  • Zeitstempel von Unix-Timestamp auf ISO8601-Format umgestellt
  • Netzwerke in CIDR-Notation
  • API Generator validiert

Änderungen am Generator

  • Die Eingabefelder wurden umsortiert. Pflichtfelder verstecken sich nicht mehr hinter eingeklappten Elementen
  • Der Generator kann API-Dateien validieren. Entweder wählt man seine Datei aus dem Auswahlfeld über dem Textfeld oder man kopiert den Inhalt einer Datei in das Textfeld
  • Bei der Validierung werden die Daten direkt in die Formularfelder kopiert, so dass sie danach gleich bearbeitet werden können
  • Gültigkeit von API-Dateien zeigt der Generator farblich an
  • Das Ergebnis der Validation zeigt die problematischen Felder an, man muss sie nicht mehr erraten
  • Zeitpunkt der letzten Änderung und API-Version setzt der Generator automatisch beim der Erstellung, wenn die Eingaben gültig sind

Weitere Änderungen

  • die zusammengefassten API-Dateien legen wir mit jeder Erzegung gesondert ab, um später die Entwicklungsgeschichte verfolgen zu können (Anzahl Communities, Anzahl Router, ...)
  • Es gibt mehrere Ansätze, z.B. die Anzahl der Knotennummern in den API-Files automatisch aktualisieren zu lassen. Solche Scripte und Anleitungen sammeln wir im Github-Repository common.api.freifunk.net 

Die gesamte Änderungsgeschichte ist Github-Repository aufzufinden. Fehler, neue Anforderungen oder Anregungen meldet ihr bitte auch im Github unter "issues".

Freifunk Google Summer of Code 2014

We are excited that Freifunk has been accepted as a Google Summer of Code Mentor organization again in 2014.

We are now looking for interesting student projects. Participating community networks and projects have already put up a list of ideas on the wiki.

Students can apply for example for projects developing packages for OpenWrt (the basis of the freifunk firmware) extending its functionality or other useful network tools such as management server tools, graphic interfaces for existing tools, map extensions, p2p tools that take routing into consideration, implementing wlan sleeping modes, routing protocols and more.

The deadline for student applications is 21 March: 19:00 UTC. We recommend to start your application now. You also need to add an enrolement form into the system.
