Hi all,
I'm one of people who started www.meshpoint.me - idea is to build open
source wifi router that can be easily deployed in any type of crisis
situations.
I have been setting up wifi networks in crisis situations and I know
that there are no devices that are usable in crisis situations.
Belive it or not but first responders usually aren't network admins :)
So that is why we started developing MeshPoint, wifi device that
anybody can use in crisis situation.
First iteration will use off the shelf components and later we plan
develop our own wifi router board using atheros hardware.
Our current design (as you can see on the web site) uses three TP-LINK
WR842ND (AR9341) boards in 3D printed case.
Our concern is that this could generate too much interference and
cause too much L2 retransmissions because of co-channel interference.
We are using latest OpenWrt 15.04 Chaos Chalmer and ath9k driver and
would like to know if it is possible to extract metrics that shows
number or L2 retransmissions.
Do mac80211 or ath9k tracks L2 retransmission statistics?
How can we get those metrics if they do?
>From my research up to 5-10% of L2 retransmission is just fine, but
anything over that is cause for great concern.
Is there any other metric that you would suggest we track that would
show some issues due to wifi interference?
Is there anyway to get AR9341 datasheet?
Cheers,
Valent.
I am in california briefly (for a conference) but have time free after thursday.

Hey folks,
There's gonna be an hour or so of network downtime tonight. I just got an email from digital ocean saying that we've received too many dmca complaints and that they're gonna bring down our server until I respond to the latest one. I'm out of the house for the next hour and I don't know that I can deal with it until I get back.
Sorry about this - I'm gonna try to get this fixed asap and avoid this moving into the future.
Thanks,
Max

Hey folks,
I wanted to let everyone know about this event that will be happening in
Richmond this Saturday, Nov 21st. Sudomesh/peoplesopen.net is a co-sponser
and will have a table there. I don't have a particularly good idea of what
it will look like, but I do have a ton of respect for the work that BBK and
OTX do and it'll be a really good opportunity to see what grassroots
digital literacy work looks like.
The fair will be at:
Building Blocks for Kids
312 9th St, Richmond, CA 94801 (a pretty short walk from the BART station)
11/21/2015 10am - 1pm.
We were asked to show up at 9am to prepare for tabling, etc. I'll be there
to bottom line it, but if other folks want to show up and talk about
sudomesh/peoplesopen.net I'd love the company.

Stop by sudo this Thursday at 8pm and meet Musti, inventor of the open
hardware optical wireless system KORUZA <http://koruza.net>. KORUZA is a
1Gbps wireless optical system for locations up to 100m apart, using an
eye-safe infrared light beam. A low cost, open source and open hardware,
wireless optical system, making the free space optical (FSO) technology
available to masses and providing an alternative to Wi-Fi networks for RF
spectrum congested urban areas.
*Design for imperfect manufacturing and challenges of making wireless
optical system KORUZA*
Complicated and precise systems can be designed more smartly with imperfect
tools and machines, demonstrated by the example of KORUZA, a low-cost
wireless optical and open source open-hardware system for gigabit 100m
wireless communication in urban areas. Motivation for developing this
project comes from Wi-Fi, which is the most popular choice for creating
low-cost networks these days. However, a large number of such networks fail
to co-exist in urban environments due to RF spectrum congestion. KORUZA
solves this problem by using a highly collimated optical beam for
bi-directional communication. In this talk I will discuss the use of 3D
printing for development of precise optical setup with imperfect parts, how
to design a system using and re-purposing mass-produced off-the-shelf
components, discuss impacts of setting up a global distributed experiment
World Wide Koruza l experiment and observing the developed product in
real-life. I will also demonstrate the latest KORUZA 1.0 prototype now
suitable to make wireless optical gigabit links between buildings.

Hello All,
I am going in a trip from Nov. 3rd to the 11th and I have no place to park
my car for that length of time.
If someone in the list living near BART would allow me to park in their
driveway or similar; between Richmond to SF Airport I would donate $50 to
Omni (https://omnicommons.org/donate.html). It will make me happier knowing
that I am donating that money Omni, besides that it will way cheaper than
paying the airport!
I would share the receipt of my donation with you.
Many thanks in advance,
Daniel
p.s. please feel free to email me directly to my email or ask me for my
number if you prefer to call. Thx!

Our last Tuesday of the month general meeting is tomorrow, Tuesday October
27th at the Omni!
We've been busy alpha testing the network and have been getting some
promising results! More info on that process can be found here:
https://sudoroom.org/wiki/Mesh/Blog#Alpha_Testing_Network
We're especially interested in finding a handful of new folks who would
want to host nodes. If you're willing to share some of your home bandwidth,
generally reliable, and interested in our project, it's a great way to
learn about the network while helping us out a lot with very little initial
investment! If you're able to email me in advance of the meeting letting me
know that you're interested in hosting a home node, that would be
especially helpful, but if not that's ok too.
We take notes of our meetings (which everyone is encouraged to check out
even if you're not in attendance) here:

https://sudoroom.org/wiki/Mesh#Join_Us
Hope to see you there!
Hello All!
Straight to the point:
Instead of going to buy a new/used piece of furniture or whatever item from
a store, one should ask in their Collecive and or the Omni email list(s).
So if a member has it, then the two parties involved will decide the amount
of money that the person receiving the item should donate to Omni. This
idea is not inclusive to items, it could include services.
For example (a real example): I am going in a trip for 11 days (Nov 3 -
11), and I have no place to park my car for that length of time.
If I use the parking lot at the airport, it will cost me $18 a day making
it a total of $198 plus tax. But, I would be happier if someone in the list
living near BART would allow me to park in their driveway or similar; from
anywhere in Richmond to North Oakland, or from SF to the SF Airport so that
I would donate $50 to Omni.
The person doing the monetary donation could do it in person or use the any
of these methods online: https://omnicommons.org/donate.html
What are your thoughts?
Many thanks for reading this email.
Daniel
p.s. i will send another email with my real #ISO request as an example of
what I mean, and perhaps I get some replies.

Subject: dan gillmor nails why I just did what I did
From:
http://www.slate.com/blogs/future_tense/2015/10/15/trans_pacific_partnershi…
"Surely our government isn't insane enough to thwart research designed
to keep us safer in the emerging “Internet of Things.” Yet tell that,
for starters, to the automobile industry, where one of the world's
largest car makers, Volkswagen, cheated on emissions testing by
tweaking its software. This crime against humanity—not an
exaggeration, given the massive contribution this may have made to
accelerating climate change—was discovered by researchers who, by good
luck, discovered that VW's cars had been spewing vastly more
pollutants than the company claimed for years. This almost certainly
would have been uncovered much earlier had the industry not relied on
the Digital Millennium Copyright Act to “protect” its software from
analysis; the DMCA made it illegal to circumvent “digital restrictions
management.” Yet the automakers continue to adamantly oppose any
exception to the DMCA.
This TPP provision, assuming it's in the final document—won't it be
great when our government allows us to actually see it?—is just one of
the many, many terrible “intellectual property” arrangements aimed at
giving corporations greater control over their customers. When
software is part of a product, as it is in so many things today and
almost everything tomorrow, the very concept of ownership becomes an
abstraction for the alleged buyer. And when we risk harsh penalties
for even attempting to repair a device that's defective, whether
that's because of the seller's incompetence or venality, we are in a
totally untenable, and frighteningly insecure, position.
We need to be going in precisely the opposite direction, and a
too-little-noticed proposal this week shows how it might be done. A
group of security experts looked into the absolutely horrifying, and
willful, lack of security in devices most of us use every
day—especially the Wi-Fi routers that let us share one Internet
connection among a variety of devices—and asked the Federal
Communications Commission to intervene.
In a letter to the FCC and a press release explaining their goals,
more than 250 people, including Vint Cerf, one of the Internet's
creators, implored the agency to make these crucial devices more
secure by forcing manufacturers to be more open about how they work.
Among other things, the security experts asked the FCC to require that
device makers a) provide public access to “source code”—the
programming instructions that operate the device—so that it can be
analyzed; b) provide ongoing security updates in timely ways; and c)
be prevented from selling devices that don't comply with those and
other rules designed to ensure security.
The FCC should make this happen yesterday. Then, regulators and
Congress should extend the compelling logic of this proposal to other
devices—notably cars and mobile phones—that are notoriously riddled
with flaws.
Meanwhile, it's vital that Congress not agree to the TPP as it's
currently written. Thankfully, the deal is in trouble. Let's hope the
odd-couple combination of a corporate-dominated Obama administration
and a Republican-controlled Congress doesn't override common sense and
the public good."
Scientists and Engineers have a mandate to obey physical law. Lawyers,
and lobbyists, not so much.

I'm thinking that I'd like to do some updates/maintenance to the (dev alpha

I was thinking probably midnight tonight (Thurs 10/15). I know it's a
little late notice, but I think it may help with some of the issues we've
been experiencing. If everything goes correctly, it should be about 15 min
of downtime around midnight.

Subject: BREAKING: TPP text leaked
To: danarauz(a)gmail.com
*Last week, WikiLeaks released the final text of the TPP’s intellectual
property rights chapter and it is absolutely terrifying.*
*These are just a few of its most dangerous pieces:*
-
Compel ISPs to take down websites without any sort of court order, just
like SOPA. (Appendix Section I)
-
Extend the US’s copyright regime to require copyrights stand for life
plus 70 years, preventing anyone from using works that belong in the public
domain. (Article QQ.G.6)
-
Criminalize whistleblowing by extending trade secrets laws without any
mandatory exemptions for whistleblowers or investigative journalists.
(QQ.H.8)
-
End anonymity online by forcing every domain name to be associated with
a real name and address. (Article QQ.C.12)
-
Make it illegal to unlock, modify, or generally tinker with a device you
own. (Article QQ.G.10)
-
Export the US’s broken copyright policies to the rest of the world
without expanding any of the free speech protections, like fair use.
(Article QQ.G.17)
*The worst part is that this is just one of the TPP’s 30 chapters. *
*The final text confirms our worst fears — click here to take action
demanding Congress vote NO on the TPP.
<http://list.fightforthefuture.org/mpss/c/2wA/ZgwNAA/t.1ra/JRRvvf--QMGuoqxOh…>*
For years, governments have held critics of the massive Trans-Pacific
Partnership agreement in a perfect catch 22. Officials brushed off public
outcry and concern by claiming that the dissenters didn’t have all the
facts.
This was by design—the 12 country trade deal was negotiated entirely behind
closed doors by industry lobbyists and government appointees, and even now
the text of the agreement is still classified.
But late last week, WikiLeaks released the final text of the Intellectual
Property chapter, meaning those excuses won’t work anymore.
*We’re planning to go all out against the TPP, but the first step is to
make sure Congress knows just how many people oppose the TPP. *
*Click here to take action demanding Congress vote NO on the TPP.
<http://list.fightforthefuture.org/mpss/c/2wA/ZgwNAA/t.1ra/JRRvvf--QMGuoqxOh…>*
Taking action today is just the beginning, because if all we do is send
emails and make phone calls, Congress is not going to reject the TPP. Too
many giant industries are seriously invested in making sure Congress
ratifies the TPP.
*If we’re going to win, we need to go big. Which is exactly what we’re
going to do.*
*So take action right now. Contact your Congresspeople now and tell them to
vote against the TPP
<http://list.fightforthefuture.org/mpss/c/2wA/ZgwNAA/t.1ra/JRRvvf--QMGuoqxOh…>*.
Then get ready to do more because we’re going to unleash some of our
strongest campaigns ever.
Already we have plans to work with hundreds of different groups as a
massive coalition to fight the TPP, coordinate gigantic on-the-ground
protests in key cities across the country, and produce compelling content
to spread the word to as many different audiences as possible just what is
at stake in the TPP.
*To do all that, we need your help — if you can, pledge to chip in $5 every
month between now and when the TPP fight ends so that we can run our
biggest, boldest, and best campaign yet.
<http://list.fightforthefuture.org/mpss/c/2wA/ZgwNAA/t.1ra/JRRvvf--QMGuoqxOh…>*
Thanks for all you do,

Subject: Setting up an experimental testbed for wireless mesh network
To: mesh-owner(a)lists.sudoroom.org
Thank you all for creating such a wonderful group.
I am a student studying Digital Communications in India. I am trying
to set up a wireless mesh network covering the whole campus of our
college.
I have currently 10 routers (TPLINK WN1043ND) updated with openwrt.
I have been trying to run the BATMAN-ADV and 802.11s protocols in
these routers, but unable to do so. Once set-up, my objective is to
use it for video-surveillance system.
The following configuration is what I want:
Node1: 192.168.99.25
Node2: 192.168.99.26
and so on..till Node15
I have followed the steps in
http://www.radiusdesk.com/technical_discussions/batman_basic
completely, but it still doesn't work.
Please help. It would be helpful if the configuration files for
setting up mesh with 802.11s (HWMN) can be given.
All:
As of yesterday, we have a new Internet connection originating at my house
<http://map.sudomesh.org/select/phorzaith/>, and shared with Jake's and
Marc's (is that LiveLabs2? Y'all ain't on the map!) and other neighbors.
There are a few significant bits of news here. I may be repeating myself on
some of this:
- We're using Megapath business services as our ISP. In our case,
they're reselling Comcast cable service -- the only reasonable/available
option here. They are good because (1) there is no restriction on sharing
or even reselling service; (2) it includes a Service Level Agreement, i.e.
guaranteed uptime threshold. All that (especially #2) means that it's
somewhat more expensive than other options, but we don't care -- it fits
our needs. And having at least one node we can talk about very publicly,
without fear of ISP objections, seems very worthwhile.
- The account is in Sudo Mesh's name, meaning that we could
theoretically set up additional nodes. (But in practice, I will be paying
the bills and collecting others' share -- so let's only do that if we have
rock-solid payment processes in place first.)
- We're dividing this up in an interesting way, that might be a useful
model. Marc and I are serving as "primary node sponsors" because we each
rely on the connection for our work. We are taking responsibility for
making sure the bill gets paid, even if others don't participate. In
addition, we have up to four other households (in my house and next door)
that we hope to join in, paying $30/month each. All have agreed at least
tentatively. And if they do participate, we can extend the availability of
the free #peoplesopen.net SSID from their homes too! The neighbors like
both the idea of cheap Internet, and the idea that they are helping promote
a social good.
- I wrote up a one-page explanation for those neighbors. I'll post a
sanitized version of it on the wiki soon; hopefully it can help serve as a
model for other neighbor arrangements.
- As it turned out, one of the neighbors (Frank) had FOUND the free WiFi
node already, canceled his ISP, looked up the People's Open web site, and
was enthusiastic about the idea before I even brought it up to him! He also
paid his first month proactively, as soon as I suggested the idea. So, this
is a good indication that our idea is working!!
Thought you'd all enjoy knowing about this. Please feel free to hit me up
with questions or ideas!
