Fwd: [guifi-euskalherria] [guifi-users] Próximas actividades de Guifi.net

by al

Hello. After libre-mesh speech in Hackmeeting 2013 - Sestao, a local person from Euskal Herria send to Libre-mesh crew congratulations and ask about to start to use it in his zone (see below). I'm gonna answer asking about if is rural area or city (for interferences in 2,4GHz, but I think he lives in rural area) and explain him possibility to have roaming. I think we can help him with a pre-tested binary for his zone, explain that we are in pre-beta release, but qMp project and Altermesh project are in production in several communities. He has tech knowledge. ----- Mensaje reenviado ----- De: "Asier Garaialde - GipuzkoaShare" <agaraialde(a)gipuzkoashare.net> Para: guifi-euskalherria(a)llistes.guifi.net Enviados: Martes, 5 de Noviembre 2013 10:15:17 Asunto: Re: [guifi-euskalherria] [guifi-users] Próximas actividades de Guifi.net Kaixo Al, Me gustó mucho la charla que disteis sobre LibreMesh y quiero empezar a hacer unas pruebas. El firm de LibreMesh esta ya suficientemente 'maduro' como para hacer pruebas en semi-producción o todavía está para utilizar únicamente en entornos de testeo? Me lanzo a probar con LibreMesh o todavia es conveniente usar qMp? Pues eso... Me hubiese gustado quedarme para charlar con vostros mas tranquilamente pero por rollos del curro, el sabado por la tarde tuve que salir escopeteado... Aio!

CONFINE Open Call

by Nicolás Echániz

Hi all, I know some of you are skeptic about presenting projects to CONFINE, but I believe, from what I've been able to talk to different people involved that we have a chance with libre-mesh. I have already agreed with the head of the Networking department at the Universidad Nacional de Córdoba (a reowned University in Argentina) to present the proposal from their institution. I've also checked that Argentina is one of the eligible countries, according to: http://cordis.europa.eu/fp7/ict/programme/home_en.html I've also confirmed that the closing date will (most likely) be extended. So... I've started writing a proposal in this pad: http://etherpad.guifi.net/libremesh-proposal (only the abstract is written so far, the rest is just the template) I'm working on this with Daniel Britos, from the UNC, but I've been thinking that others on the list might have some time to help, specially Isaac :) I want to have a good head-start during the next few days and I plan to finish it during the first days of our return to Argentina (although I need to confirm the CONFINE closing date). Ok... so that's the plan, anyone who wants to help is welcome. Cheers, Nico

Google Summer of Code 2014

by Gioacchino Mazzurco

Hi! I have participied with ninux to google summer of code for two years as mentor, this year i have the feeling ( not confirmed ) that ninux is not mooving on for GSoC for some internal iussue. With GSoC we can take ~5k$ for each students ( for example me and p4u ) participating and 500$ for each mentor participating ( for example nico end gui ), the only draw back is that we need to prepare some burocratic stuff What do you think, is guifi participating this year? I think 10k$ would be a good sprint for libremesh project ( without google noticing we can handle that money as we prefere... )

New network in rural areas in Brasil

by al

Hello from Guifi.net - Catalonia. People from a rural hacklab in Itatiaia (Brasil)[1] are going to suporpt a intensive project for start to develop a free, open and neutral network in rural areas in Brasil. 1st part of project start September 5th until 20th. We're going to research social, economical and technological reality in rural areas in Brasil, to make some links in this area and to develop free software for their needs. Of course I was thinking to do it with Libre-Mesh in cheap routers and I hope some of you find this project interesting to come to work on it together. They pay travels, food and host for a little team (3-4 people). I can not to decide who (they do it), but they tell me that if I know about people that have the profile that I contact them and say them that tomorrow 13th or 14th they are going to open the call to collaborators. So, you are the people with perfect profile :) They are going to choose first people that propose him or herself to the project. At same time they are 3 or 4 other several projects about rural and tech's. After this meeting we want to continue development of free networks in Brasil and we're going to work in to get more supporters in contact with "forumdainternet.cgi.br", "Tropixel" and "Saravea.net". Thank you! PD: Some of you can give me permissions to edit Libre-Mesh wiki? My username is "al". Thank you. [1] http://nuvem.tk/

Definition in english of Libre-mesh in home page, please correct expressions

by al

Hello, this is a call for native English-speakers ;) We made a definition of project. We made it in Spanish and then we translated it to English, so the concept is good but maybe the expressions used on it are not much. So maybe you Isaac (or other native English-speakers) can take a look. http://www.libre-mesh.org/ Spanish original is here: http://es.wiki.guifi.net/wiki/Libre-mesh Thanks.

quick comments about bmx6

by Gui Iribarren

just to note down what we talked yesterday: 1) on the wiki, http://bmx6.net/projects/bmx6/wiki/Wiki#Blocked-Nodes there's no mention at all that the module "ip6_tunnel" is needed, probably useful to note on compile/install section? 2) there's also no documentation whatsoever about globalPrefix only thing i could find is on the help: --globalPrefix <NETWORK>/<PREFIX-LENGTH> specify global prefix for interfaces but from what i tried, if a globalPrefix is set for an interface (or globally) and the interface doesn't have any ip on that prefix, then it does not get an autoconfigured fd66:66:66 either, and the interface stays disabled. I don't know if that's on purpose, i expected that if the interface had no address in that prefix, it would get activated anyway with the usual fd66:66:66. in any case maybe doc should be more verbose about how it works? finally, 3) you asked for some links about tunnels: tinc-vpn is the mesh vpn, that works perfectly and is a great idea, but being userspace it kills cpu with high traffic http://tinc-vpn.org/ tunneldigger was made by slovenian people, is a simple userspace daemon that sets up L2TP tunnels (kernelspace) to a set of tunnel "servers" https://wlan-si.net/en/blog/2012/10/29/tunneldigger-the-new-vpn-solution/ high traffic is not an issue, but it works in a hub-and-spoke model, there's no mesh concept whatsoever cheers! gui

Libre-mesh.org down

by al

Hello from Brasil. I'm working on Libre-mesh network deployment here for two weeks. I need resources as map, code, firmware,... Now all is down. Please can you give up again? Maybe we can make a on-line backup server in order to have high availability and not to depend just for one server. We can have a redmine/nginx stable and the other one for testing. (I said that because we had two downs just last month, please, I'm a little bit worried).

#libre-mesh on IRC bridged with libre-mesh on RetroShare

by Gioacchino Mazzurco

Hi! Thanks to help of people on retroshare we achieved to have #libre-mesh on freenode bridged with libre-mesh on RetroShare so now we can chat on bot networks with all, the only glitch is that people on one network will not see people on the other but just on the list, the messages will be relayed by the Bridge nick that will report real author as part of the message This is an important step, RetroShare is a P2P secure and encripted netwok, so there is no need for servers, it is just like mesh but on layer 7 and it is particular important because it will encourage local traffic instead of remote one, and decentralization that is all good for our fredom networks :D Also ipv6 for retroshare is in plan for 0.6 version ( we are at end of 0.5.x series ;) so we will have it soon ) And i am developing the GUI for androis so we will have scure messaging on phone too ( VoIP is in plan we already have some working plugin prototype so soon secure call too :D ) see you!

Quagga is a suit which includes several routing protocols. Quagga could be used to federate bat-adv and bmx6. But if you are speaking about use static routing, I would just say it is a big mistake (what happens when you have to paths to the same cloud?). >> Why? because BMX6 (100% rewritten fork of Batmand with native >> IPv6 support) is very powerful and produces a very low overhead >> (see [6]). > > But how does this overhead compare with speed of convergence > (adaption to the changes in the mesh).

However I can say this test was made during the WCW-Berlin. The scenario was around 15-20 nodes (ask UFO to to know it better) in a mobile scenario (it means someone moving nodes). All protocols were running at same time in different VLAN (see battlemesh firmware in github) so all of them were in the same situation. Just to give you another detail, the tested protocol which showed more difference between moving and not moving environment was Babel. By the way, the conclusion of this tests was: BATMAN based protocols are better in the overhead-mobile test. > Mitar > Cheers, Mitar.

From libre-mesh

by Pau

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. My name is Pau from Barcelona. I have heard about your project in the battlemesh mailing list. First of all, congratulations for starting such kind of initiative, I hope you succeed. In my place I'm working in the development of a Mesh firmware named qMp [2] which is being used mainly in our community network Guifi.net [3]. The purpose of sending this mail comes from what I read in your Wiki [4] about create a new firmware. IMHO it is a mistake since there are several projects already created, probably too much because we are dividing our strength. Recently (thanks to the battlemesh and other events like that) we have started a new project to put all the development efforts together and make a firmware generic and useful for everybody. The idea is to make a meta-firmware which can be used as basis to create specific community firmwares. The project is named libre-mesh [5]. Until now three existing mesh communities have joined: Guifi.net (Catalonia), AlterMesh (Argentina), Eigennet (Italy). I would like to invite you to participate. We have a huge experience in the OpenWRT-based distributions for mesh networking, I hope you are able to take advantage of it. I don't pretend to start a large discussion about routing protocols, but I would like to summary our conclusions because they can be useful for us. Batman-adv is very nice, but you cannot have a single collision domain cloud for all the nodes because it does not scale. So, the network have to be splitted in several clouds. To federate them a layer3 routing protocol is needed, so here is where we use BMX6 [7]. Why? because BMX6 (100% rewritten fork of Batmand with native IPv6 support) is very powerful and produces a very low overhead (see [6]). Here [8][9] find a couple of small diagrams to understand a little better this model. Cheers. PS: do not use ARC Freestations, they use Ralink USB chips and driver is bullshit in ad-hoc mode.

sort of sprint...

by NicoEchániz

Hi guys, Guido and I will be working during the whole next week on libre-mesh stuff. Our work time will be starting at 12 UTC every day of the week. We would like to work on this topics: * properly debug and report outstanding batman bugs: OGM starving and ttvn drops. * test the configuration guido and gioaccino did in Berlin on a local testbed. * start working on auto-configurtation scripts, looking into the existing work done during the battlemesh and afterwords. * luci-based web interface for antenna alignment It would be nice to work together with the rest of you if you have some time available during the week, so we can get the ball rolling. Cheers, Nico

meeting

by NicoEchániz

Hi txantxitos, I wanted to let you know that after some weeks of network instability here in Quintana while we tested a more recent revision of OpenWRT/AlterMesh I am now done with that so I can get back to other things. How about your time schedules? Could we agree on an IRC (#libre-mesh) meeting for this week to organize the work ahead? It could be Thursday at 4PM Barcelona, 11AM Buenos Aires for example. Are you guido on a plane at that time or is it oK? Cheers, Nico PS: I am seeing an error (502 Bad Gateway) in: https://dev.libre-mesh.org/ Guido could you have a look?

Fwd: [Nodogsplash] LuCI page for configuring Nodogsplash

by NicoEchániz

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Maybe this can be of some use to us... it would also be an excuse to interact with the Commotion guys. cheers, Nico - -------- Original Message -------- Date: Wed, 29 May 2013 10:03:56 -0400 From: Dan Staples <danstaples(a)opentechinstitute.org> To: nodogsplash(a)ml.ninux.org Subject: [Nodogsplash] LuCI page for configuring Nodogsplash Hi all, As part of another project, I created an OpenWRT LuCI page for configuring Nodogsplash (similar to luci-app-splash). It lets the administrator set leasetime, which interfaces/zones to captive portal, whitelist and blacklist MACs, whitelist IP ranges, and set the splash page text. It's certainly not all the Nodogsplash options, but enough for a simple setup. The Nodogsplash default splash page I include also uses a simple javascript redirect to point to a LuCI-created splash page, which allows you to use your router's web interface theme and include LuCI headers/footers and whatnot on the splash page. Just wanted to throw it out there in case it would be of use to anyone. The source is here: https://github.com/opentechinstitute/commotion-splash I would love feedback on it if anyone has any. I also haven't tried it on vanilla Attitude Adjustment, I've only used it as part of the Commotion OpenWRT-based firmware. So the one caveat is that it depends on a small lua file being present in /usr/lib/lua/, which can be found here: https://github.com/opentechinstitute/luci-commotion/blob/master/luasrc/comm… cheers, Dan - -- Dan Staples Open Technology Institute https://commotionwireless.net _______________________________________________ Nodogsplash mailing list Nodogsplash(a)ml.ninux.org http://ml.ninux.org/mailman/listinfo/nodogsplash -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQEcBAEBAgAGBQJRpi7dAAoJEPHORz17N0TFOKYIANRQuLr74RU+H0rtXa26KInh cWOLlrYLi6sjB02NFL1kID7C2pVaWV+F/oYghTs//Z9PZM1EwmqP3OZwm4mB4Vni EWxN8Ol+Mlf2XVJkntAlSNEShzNFrt9VDt6dz1+eJ43Pwy21IYFdJ1wfXpKvkRQ5 /UkajGkAKk5Pl2jAy7r3WBwIUh74KlpyklEQvQlkbWdTZk1SezErci2HbTGo5VLz MI69cYtoHNLcDH8ChHQAooTCnTH3OgWEte2t6ZMZBcz03hFpV91PIb+HlKBBtLpS zrZWDctHal5hoKP37wv582nLPWClr9onc+AtAHs7UTESNI5798xf+5B/S3qjOR4= =qqdW -----END PGP SIGNATURE-----

autconfig/autobuild

by Gioacchino Mazzurco

In eigennet firmware we really didn't have a build system, so have an autconfig script inside the device make a lot of sense, but in libre-mesh we have lime- build and chef, so were we put the limit between autobuild and autoconfig ? Autoconfig works well on simple devices like picostation or nanostation, but on more complex setup like the black tplink is not the good approach, so i was thinking about completely moving to a build + profile system without or with minimal autoconfig script on the device what do you think about that ?

qmpfw y Chef

by NicoEchániz

Hi Pau and SAn, during the brainstorming sessions that gave birth to libre-mesh we talked about integrating qmpfw and the firmware Chef. Pau and SAn are the guys behind the development of these tools, maybe it would be interesting to start coordinating how this can be actually implemented? Cheers, Nico.

magic icmp

by Gioacchino Mazzurco

I saw that it depends on libpcap, it is the only way to listen for icmp messages? In this case i think it is not the case to use icmp protocol and instad would be simpler and more performant just a simple udp multicast socket like bmx6 do

Batman-adv bla II backbone

by Gioacchino Mazzurco

I have talked today with antonio (ordex) and really what they call backbon is not the common sense of backbone, so we should add a vlan on top of ethernet interfaces where client are accepted too if we want batman-adv to route traffic accross ethernet too

Fwd: News in libremesh

by Gioacchino Mazzurco

Is p4u receiving mail from the mailing list or there is some problem ? ---------- Forwarded Message ---------- Subject: News in libremesh Date: Wednesday 15 May 2013, 00:06:01 From: Pau <hakais(a)gmail.com> To: NicoEchániz <nicoechaniz(a)altermundi.net>, Gioacchino Mazzurco <gio(a)eigenlab.org>, Gui Iribarren <gui(a)altermundi.net> Hi. We are currently using the the repositories created in github. I see Gio added the package for cracking the ath9k regdomain. I added a dummy package named lime-system with some basic dependences. If you clone the repository lime-build and type "make T=tl-703n J=2", it should compile the system with the lime-system enabled and the dependences. For the moment only the targets tl-703n and tl-wdr4300 are supported, but it is just a mather of adding the config files in the configs/directory To create them execute - make T=NEW_TARGET menuconfig - find the resulting config file in build/configs/NEW_TARGET - diffconfig it with build/ar71xx/scripts/diffconfig (yes, it should be added to the Makefile to do it automatically, please volunteeers!!) - save it to configs/NEW_TARGET Following this approach we can have kind of useful diferent profiles for each target. So, some software can fit in devices such as wdr4300 and not in 703n. I also have been thinking about the network architecture modes (NAM). I think we should implement some of them and let the administrator choose (can be different for each community). - bmx6 + bat-adv in all nodes - bat-adv in all nodes and bmx6 in the borders (autoloaded) - bat-adv in all nodes and bmx6 only in the nodes designed by the administrator [1] https://github.com/libre-mesh PS: Do we have mailing list? -- ./p4u -----------------------------------------

[Dev] roadmap / issues

by NicoEchániz

Amici, I converted Pau's Roadmap wiki entry into individual issues, so we can have more complete information on each task: what is expected, who will be in charge, etc. I marked all issues with lime-alpha as target version just to have them grouped. It's here: http://dev.libre-mesh.org/projects/libre-mesh/issues And I updated the link in the wiki to point there. If we are all ok, we can delete the Roadmap wiki page and keep using the issue system for future tasks. Cheers! Nico
