Buenas,
Más abajo les envío una presentación que hice hace unos años en la lista de
AlterMesh.
Les cuento que actualmente el proyecto tiene instalados 3 routers wdr3600
en 3 instituciones del Barrio Villa Aguirre, Tandil, pero actualmente no se
provee ningún servicio. Estos equipos los instalaron alumnos de la TUPAR en
el marco de un trabajo de la materia Tecnología de Redes 1.
La versión que tienen instalada los equipos es:
lime-tl-wdr3600-v1-r44952-tandillibre-node-factory.bin
lime-tl-wdr3600-v1-r44952-tandillibre-node-sysupgrade.bin
En este momento en una de las instituciones se está instalando un servidor
que hará de portal cautivo y alojará algunos contenidos (wikipedia,
owncloud). El servidor lo están configurando como trabajo final de la
TUPAR.
Estamos teniendo problemas para lograr que el router otorgue como DNS la ip
de servidor.
Pero si te conectas al wifi y le pones manualmente el DNS (10.233.0.55)
funciona perfecto. (video
<https://drive.google.com/open?id=0BzqwAzOcjbGkYVM2V0xyRFpfYTg>)
Si tienen alguna guía de como configurar el equipo para vincularlo al
servidor de DNS del servidor, nos vendría genial.
También me comentaron los chicos que cuando el equipo pierde la corriente
se borra la configuración. ¿Se les ocurre por que puede ser?
Saludos y gracias!
Santiago

Buenas!
Me presento, mi nombre es Santiago Vallazza, vivo en Tandil, Provincia de
Buenos Aires, Argentina y trabajo en la Facultad de Ciencias Exactas
<http://www.exa.unicen.edu.ar/> de la UNICEN <http://unicen.edu.ar/>. En
esta Facultad tenemos varias carreras, las relacionadas con Sistemas son:
Ingeniería de Sistemas, Tecnicatura Universitaria en Programación y
Administración de Redes (TUPAR) y este año arrancó la Tecnicatura
Universitaria en Desarrollo de Aplicaciones Informáticas (TUDAI).
Soy usuario y militante del Software y la Cultura Libre, hace unos años me
metí en redes pero no pude darle mucha continuidad. Ahora tengo ganas de
retomar el tema.
Ahora estamos con un proyecto que propone crear una red inalámbrica de
alcance barrial, que provea contenidos educativos e informativos. La idea
es poder acceder a contenidos que estén en el servidor del proyecto, que
ubicaremos en una sede de la UNICEN, la Universidad Barrial, y en los
servidores de las escuelas que participen (moodle, etc.).
Del proyecto van a participar algunos estudiantes voluntarios y se
trabajará con docentes y cátedras de Comunicación de Datos de la TUPAR de
Ingeniería de Sistemas, y en ese marco algunos estudiantes realizarán
trabajos de cátedra y de final.
Nos gustó el proyecto Altermundi y el alcance territorial que tiene y el
firmware Altermesh, así que intentaremos usarlo como firmware oficial del
proyecto, y si podemos hacer aportes, también lo haremos. Ya he contactado
a algunos miembros de Altermundi por sus correos personales, pero creo que
este será un medio más apropiados.
Eso es todo por ahora, y en otro hilo comienzo con algunas preguntas.
Saludos!
Santiago
Thinking about how we might use the voucher system for access control in
Caimito and other communities in the area...
1) I imagine the process might be that someone connects to the wifi,
opens a browser (or on Android, sees a notification to register on the
network, like in airports), gets caught by the captive portal, and has
an option to use the network without registering, or enter a voucher
code. Correct? Other options?
2) In order to make the voucher code as easy as possible to use, three
options occur to me:
-- 1) the code is 2 or 3 letters (maybe up to 6), case insensitive,
automatically generated by the system. (My favorite)
-- 2) the code is a word or pair of words, automatically generated by
the system. (My least favorite)
-- 3) the code is defined by administrator, and checked by the system to
avoid duplicate codes. (Maybe useful in some cases)
Letters instead of numbers because we get more options for each digit,
thus making a shorter code.
number of letters - unique codes:
1 - 26
2 - 676
3 - 17,576
4 - 456,976
5 - 11,881,376
6 - 308,915,776
Airlines tend to use 6 letters, and I can usually remember those codes.
With 2 letters, we could give unique codes to everyone who comes through
Caimito in a year, and with 4 letters we could cover 87% the province,
and with 6 we could give 19 codes to each person in Ecuador. I imagine
most community networks would be fine with 3 or 4 letters. Maybe the
length of the code can be defined by admin, or it can grow sequentially
as needed (first code is A, 27th code is AA, 677th code is AAA, so on).
3) Codes expire and get recycled, yes?
4) The vouchers are part of Pitbull, or separate-but-connected?
5) Probably "it'll be ready when it's ready, no later than October",
but... Any idea when a functional build might be ready? There are a
number of things that seem not feasible until this system works (e.g.
community library / internet cafe).
6) Can we define roles or profiles in Pitbull / the voucher admin
system? This way I can look at a list of currently active vouchers, and
see who's connected, how much time they have left, and whether they're a
library/network member, library visitor, tourist, or other. When I
create a tourist voucher, they get access to 50% of the available
bandwidth, and by default the voucher lasts 1 day. A library visitor by
default gets 90% access and lasts 1 hour. A member by default gets 100%
of bandwidth and 1 month.
7) When a voucher expires, keep the code reserved in the system for 10%
of the time it was valid, in case the person wants to renew the voucher.
Examples:
-- A 1 hour voucher of a library/ciber visitor expires, and they have a
6-minute grace period to request another hour on their voucher. The
admin interface makes extending the voucher easy.
-- A 1 month voucher has a 3-day grace period. The device doesn't have
access once the voucher expires, but renewing is easy: the admin doesn't
have to create a new voucher, and the person doesn't have to enter a new
code.
If there's a better place to share these ideas, please tell me.

Hi all
I’ve noticed LEDE supports 802.11r and 802.11w and has the respective settings section in LUCI under wireless security. I’m not familiar with these protocols other than knowing they exist and I’m very happy to see them available for use with free and open software. Is there any way we could start some testing for them for LiMe [especially the first one, which would make roaming inside the network even more seamless, since it’s one of the core advantages and of LiMe]? I read that 802.11r requires only one DHCP server to exist on the network and no separate subnets, but I assume that our replication of such a network with every node handing out the same leases on the same subnet perfectly simulates this behavior even in this respect, and the “trickery” works also for this requirement, is this correct?
Also, is there a good rule of thumb to figure out the right way of enabling features available in LuCi from the LiMe configuration in SDK? I’ve been trying to put all nodes on SSH port 42022 [I know, security by obscurity, but it’s better than nothing, and our keys are 4096, so there’s a solid base already ;] and disable password authentication for instance. Or adding hostnames, and so on. If there’s a quick way of figuring these things out, I won’t have to bother any of you for every single customization I need to make ;]
Thank you in advance

Hola! Esta es mi primera participación en la lista. No puedo escribir en
inglés pero si puedo leerlo, al menos los términos informáticos.
Trataré de usar la terminología apropiada, pero si hago mal uso de algún
término les agradezco la corrección, y aprendo un poco más.
Es la primera vez que uso LiMe me falta mucho para aprender de redes.
Estoy tratando de conectar LiMe con la red wifi de mi vecino para salir
a internet desde su conexión. Él no tiene LiMe. En el techo de su casa
pondría un access point HP V-M200 (es lo que único que tengo hasta que
llegue LibreRouter :)
He logrado establecer el enlace de radio entre ellos y obtener
respuestas de pings desde ambos lados. Desde LiMe hacia afuera, solo
puede lograrlo desde Network/Diagnostics... y no tengo internet :-(
En algún momento pude acceder a un servidor web que tengo en una de las
subredes, pero no salir a internet. Creería que el problema es el nuevo
gateway para internet que no se conoce ¿O tendría que definir reglas de
ruteo para salidas a internet?
¿Cómo le cuento a LiMe que la salida a internet no es por la interfaz
WAN del eth1? Quiero que salga por WWAN de Client "wifiVecino"?
¿Qué debo estudiar ahora? =-O
Muchas gracias por la ayuda.
Seba

Hi
I have a strange issue where sometimes, seemingly after a new gateway appears on the network, other routers that were offline during the change, cannot route internet traffic correctly even though BMX tunnels shows everything as being perfect, including the inet4 line with the exit node saying internet.
Steps to reproduce:
1] set up a node with internet access [A]
2] connect client via ethernet to a known to work second [and non-exit] node [B] which is wirelessly meshing with [A]
3] ping internet from client [it works]
4] shut down [A]
5] shut down [B]
6] turn on a new node [C] with the exact same config as [A] and connect it to the same WAN
7] turn [B] back on
Everything in luci will appear perfectly, you’ll be able to ipv6 ping any node, but any internet bound traffic will time out, even from the luci diagnostics page [not a client routes issue].
After rebooting [B], everything works consistently across reboots.
I’ve yet to try with standard 1607, but I’m using an extremely lightly modified config. I’ll do that tomorrow anyway.
Is there a way to restart batman to see if that’s the issue? [can’t find its entry in “startup”] Is there a way to restart some other service to figure out what the issue is? What should I look for in logs?
Is there a general way to force-reset something if a node sees a mesh exit-node but somehow isn’t able to route traffic to it?
Thank you
Nk
Good meshing,
Please do not feel pushed, I am just happily asking things here.
Is there any estimate on when there will be an official captive portal
solution?
In the meantime, is there anything that more or less works with Libremesh?
Sorry to come back again with this topic, we had many emails around
saying different things and I got confused.
Cheers
I joined the list a few weeks ago, and before my first LiMe post, here's
an intro:
Caimito is a community of ~40 people, with neighboring towns of ~300 and
~100, and tourists who visit. We currently have a 3 Mbps connection,
shared with the friend whose house it's in (22 km away, connected via
Ubiquiti PBE-M5-400)) and three WDR3500 routers in Caimito, all
connected by UTP cable.
Caimito: https://osm.org/go/YCpV3r1Nl--
I grew up near Houston, TX, USA, and now live in Caimito, Esmeraldas,
Ecuador. I met Nico, Jesi, and Gui in 2012, and this year I went back to
visit and joined AlterMundi. I have very little programming experience,
quite a bit of configuring-stuff experience, use GNU/Linux since 2011
(Manjaro at the moment), ask lots of questions, and avoid my keyboard
due to tendonitis. My focus over the years mixes computer tech,
agriculture, community self-determination, bioregionalism, permaculture,
group dynamics, ecologically-minded decision-making, raising
compassionate and critical-thinking kids.

Hello everyone (and Pau specially)
In our efforts to replace the wdr3500/3600 as the most accessible dual
band routers, I came across tp-link archer c50, which is pretty
inexpensive in Brazil.
The SoC is a MediaTek MT7620A, so before buying one I tried to cook an
image for mediatek with the command:
./cooker -c mediatek/generic --profile=Default --flavor=lime_default
But after a while it fails. The log file is attached. Any help is appreciated!
Bruno
