A friend of mine is involved in a project to provide low cost weather
forecasting and emergency communications in the Marshall Islands. He was
asking me about various ham radio protocols like AX.25 and it occurred to
me that a mesh network using WiFi radios might be a better solution that
could provide general Internet access for a similar or even lower cost.
The stations would need to be able to operate in remote. unattended
locations with only solar power. I am thinking that each island could have
one or more "central" sites with long distance links to one or two (or
more) other islands, and then a local network that would be used to
communicate locally on that island.
I'm still gathering more info about distances and elevations of the
islands, and whether line of site communications is possible.
Can anyone think of reasons why this would or would not be a good way to do
things?

The Wireless Battle Mesh v10
5th - 11th of June 2017, Vienna, Austria
==========================================================
The next 'Wireless Battle of the Mesh' will take place from Mon 5th -
Sun 11th of June in the Austrian Museum of Folk Life And Folk Art
(http://www.volkskundemuseum.at) in Vienna.
The event aims to bring together all people from across the globe that
are interested in wireless mesh network technologies and community
networks in general. 6 days full of expert presentations, late night
hacking sessions, measurement campaigns, protocol discussions, and a
whole lotta other meshy things.
So if you are a mesh networking enthusiast, community networking
activist, or have an interest in mesh networks in general, you have to
check this out!
Continuously updated information about the event:
http://battlemesh.org/BattleMeshV10
Location
========
We are located in the upper floor of very nice historical museum in the
middle of Vienna. One large conference room and two adjacent hacking
areas are at our full disposal there. The whole area offers nice
atmosphere and plenty of room to deploy measurement testbeds. The
adjacent park is a beautiful analog distraction, especially in this time
of the year. The metalab - a very active local hackerspace - is only 5
minutes away.
Accommodation Offering
======================
For those of you who are looking for a convenient and low cost
accommodation option: we have made block reservation for 40 people in a
nice hostel 10-15min walking distance from the Museum. The packages
include 6 nights in a four-bed room incl. breakfast - for a mere €100.
Follow the simple instructions below to get one of these hot deals a
first come first serve scheduler is used.
Registration
============
The event is *free of charge* and registration is optional - but it
makes the organisation much easier if you tell us in advance that you
plan to come.
Please send a mail to v10(a)battlemesh.org that looks somewhat like this:
########
Subject: Registration
Name and/or Nick
Accommodation package: [Yes/No]
T-Shirt Size: [S/M/L/none]
Other details you want to share: (e.g. community, country, URLs, twitter
handle, dietary restrictions, ...)
########
We will then put your name on the public participants list:
http://battlemesh.org/BattleMeshV10/Participants
And we will answer with payment instructions for the accommodation
package to those that are interested in one.
Travel Scholarships
===================
If you want to apply for a travel scholarship (compensating the costs of
a long distance flight to Vienna and back) please explicitly tell us so
in the registration mail. We will then ask you to prepare a short video
message in which you are giving a brief introduction to yourself and
your interests.
Spread the Word
===============
Please help us spreading the word by forwarding this announcement to all
lists and people that might be interested. Blogging about it is also
very appreciated, and if you do so, please add a ping-back to the wiki page:

This Tuesday at 7:30 pm we'll be getting a visit from Stephen Seymour from
San Bruno Now.
San Bruno is in the interesting and unusual situation that it owns its own
internet infrastructure and ISP. My understanding is that San Bruno Now is
a community project being headed up by Stephen to improve San Bruno, in
small ways in the short term, with some success already, but with a grander
long term vision of re-invigorating the city and attracting artists,
researchers and new energy.
There may be an opportunity for collaboration between the citizens of San
Bruno and People's Open Network here.
There is more to it but I'll let Stephen explain.
I was connected to Stephen by San Bruno resident Yosem Companys who some of
you may know as the long-time maintainer of the LiberationTech mailing list.
If you want to hear what Stephen has to say then you should attempt to be
at sudo room at 7:30 pm sharp, otherwise you can read the meeting notes at
your leisure.

Just thinking - since we now have a large inventory of nodes, maybe we could set up a demo mesh network for the workshop, something that lets people see the mesh working in real-time?
We probably don’t have time to develop a visual front-end, but could probably do something interesting with a few laptops running wireshark or some other monitoring tool.
Or, if nothing else, we could have a station where people can flash a node and connect it to the network to get a feel for how things work.
Thoughts?
(ps my nodes arrived the other day, so I’ll be bringing them by this afternoon)
Hey this is Andrew back up here on orcas.
Heres a couple links to what happened up here with creating a wifi source
for the island.
An article.

And the website.

He puts a lot of technical data too, probably tons of stuff to use.
Hi all,
Here’s my contribution to the flyer discussion - feel free to print and distribute!
I’ve also started a planning doc to coordinate everything for the workshop and make sure we’ve thought of all the details. It’s pretty skeletal right now, but I think it will be good to have all the planning info in one place: https://pad.riseup.net/p/byoi_program <https://pad.riseup.net/p/byoi_program>

I managed to get all the way through the lab; huzzah. (See the two issues
though.)
I used tshark instead of wireshark because I didn't want to install a gui,
but I think I saw what you wanted me to see.
Perhaps the next step is to interpret what I saw. We can talk about this
soon.
Thanks, Jorrit and Grant!
best,
Arthur
So I got a linux (arch) vm up and running, installed wireshark, git,
babeld, and bridge-tools (ip already installed). Cloned babeld-lab, moved
into that repository and called
sudo ./babeld-lab.sh add
as in step 1.
This is the error message I get:
vagrant@archlinux:~/babeld-lab$ sudo ./babeld-lab.sh add
RTNETLINK answers: Operation not supported
RTNETLINK answers: Operation not supported

Cannot create namespace file "/var/run/netns/n1": File exists

For what it's worth, calling this again outputs
Cannot find device "veth-p0"
Cannot find device "veth-p1"
Cannot find device "veth-n0"
Cannot find device "veth-n1"
Cannot find device "br-babel"
I'll look through the file, but my bash is a bit rusty.

Arthur
