Hello meshies
I know everybody is having fun at Battle Mesh, but if someone could take a
look at this I' d really appreciate.
I really have my eyes on the C50, as it seems to be the cheapest dual-band
on the market now. I can get on in Brazil for less than 40 USD! Last week I
bought one which I later found out to be an unsupported V2. But now I got a
V1, and it almost works. If it works, I'll the buy about 10 for an
installation in two weeks.
The problem seems to be with 802.11. The 2.4Ghz radio does not work in
ad-hoc mode - although the 5Ghz radio does. Then I don't know if it's
related, but when it meshes with a WDR3500, the Internet is painfully
slow, with some ping times about 1000-2000 milliseconds. Pinging from the
LiMe gateway at the same time gives me a steady 57ms. Perhaps a different
driver should be used?
Attached is a file with information gathered from the router.
A few other oddities (not as important as the issue above):
- Could not flash from stock directly with the compiled LiMe. I had to
first use this openwrt [1], then LiMe
- When I flash from the firmware above with the LiMe I compiled or the
download Lede, I get the message:
" It appears that you try to flash an image that does not fit into the
flash memory, please verify the image file!
Size: 7.63 MB (7.62 MB available)"
It works fine, tough.
- The firmware I cooked with my community settings (using cooker) won't go
through to the Internet, and gives this ESSID instead of my
community's:{{NETWORK_NAME}} (although it meshes with the LiMe gateway)
- The firmware I cooked without community settings connects to the Internet
through the LiMe gateway with the sluggish times above.
Thanks!

Hey sisters,
Let me share some good news for community networks -and bad ones for ISPs:
0.- Bitmessage has been working on LAN peer auto-discovery. It is
already in v0.6 branch, we tested it and it works.
1.- Retroshare will finally have asynchronous messaging working
(Retroshare already has LAN peer auto-discovery).
2.- Impressive ZeroNet is aware of the importance of LAN peer
auto-discovery and they are going to add this feature.
I just cooked a firmware with the cooker for the tp-link cpe-510. It is
similar to the nano loco m5 - 45 degrees horizontal angle, 13dbi, and 5ghz
only in this case. Costs around USD 65 here.
Everything seems to be fine. It uses adhoc mode by default, so it connected
immediately to a wdr3500 with lime 1605 from another network which I had
lying around.
The reason I'm flashing these is that we installed a small network in a
favela here last week, and the wdr3500 didn't have enough reach. Not only
the nearest nods were far (anything from 200m to 2km), but also all the
interference we had (it's a really dense neighborhood) made any link with
more than 100m very poor. The plan now is to connect the most important
nodes with those.
Abraços
Bruno

Sorry for the spam, but I thought it would be interesting for someone,
it's just the motherboard without antennas nor chassis of a TP-Link
WDR4300 for 23 € on aliexpress

Ciao,
long story short: Dopo il BM qualcuno mi ha chiesto di contattare
Panayotis (un ricercatore che conosco) per sapere dove ha preso le
device che hanno usato per uno workshop ad Atene. Ecco la risposta:

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
Hi all
I've finally had the chance to test out what some of you were saying about LiMe doing mesh over ethernet using Lan - to - Lan connections.
I have a POE switch with one cable going to a UBNT AC lite, one going to a Bullet M2, one going to a 1043ND [on its wan port] and one to an Archer C7 [on its wan port]. All 4 devices have the latest images downloaded from repo.libremesh.org, just to be on the safe side. The fifth cable is going to my ISP router [IP 192.168.111.1].
Since the lite and the bullet only have one ethernet port, stock lime configures it as a Lan port, with 10.13.0.x DHCP being handed out over it, and so on. So from the switch I have two cables going to wan ports [1043 and C7] and two going to "Lan" ports [lite and bullet] since that's what their default behavior is.
They all mesh correctly, and even the two UBNTs serve internet connectivity perfectly. The problem is that when I connect to these two devices wirelessly with clients, I often get a DHCP assignment from my ISP router [as it's on the 192.168.111.x subnet] and not a 10.13.0.x assignment.
I still don't understand how a network with not one, but several DHCP servers can work correctly. I seem to understand that LiMe can ignore such advertisements on its Lan ports, but what happens to a client that is on such wired network, say, with another cable from the switch I mentioned? Won't he receive advertisements from all servers at once? Does LiMe terminate advertisements upstream-bound when it detects others?
And in the case of the 1043 and C7 that are using their wan ports, how does LiMe understand when it should mesh with other devices over it and when it should become a DHCP client to an upstream non-mesh router in a traditional way?
And how do I solve this DHCP leaking from ISP router to LiMe routers' clients in the case of the lite and bullet?
Thank you in advance

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 Everyone,
The last LibreMesh release (I don't remember if it was announced or
not, but it is here :) ) brings support for 11s and many other things.
I was wondering... now that the wdr3500/3600/4300 devices are no longer
accessible... which ones can we use?
Now there are a lot of devices with the MTK7601, and others with
QCA6174.
I've tried some Xiaomi device that comes with the MTK7601
processor+radios and it works... but don't have knowledge about
performance and robustness... and if there are any dual radio with
weather enclosure around.
Thanks!
Hi there,
I am having some problems related to DNS. Clients of some nodes can
reach the Internet but cannot resolve names.
I do not know how DNS work in LibreMesh.
If I check the DNS settings of a client I see the anygw address as the
DNS server.
How does name resolution of Internet hosts work in LibreMesh? I mean
when the LiMe network has access to the Internet.
If there is a router sharing their Internet connection with a LiMe
network and it changes the configuration of its DNS servers,
will the LibreMesh network be affected by that change?
How?
Will the problem be automatically solved after some time?
Do I need to manually restart any service?
Thank you.
Hi,
I would like to know a bit about the routing protocol, specially when
there are several Internet gateways available. I was once told it makes
decisions mainly based on packet loss. That sounds good in order to find
the best way out to the Internet.
But, is there any kind of load-balance system so that every gateway is
used according to its capacity?
When having multiple Internet gateways, is it a normal scene to have
only one active in the whole network? Or it should normally use
different gateways at the same time?
Besides packet loss, what other criteria are taken into account to make
decisions?
Cheers!
