Inspired by last week's conversation, I experimented with MAC
randomization on my laptop. And I DoS'd my own network by exhausting
its DHCP pool.
My very naive script reset the MAC after every network hiccup, so the
router kept seeing an entirely new device and giving it a new IP
address. Slowly. Until they were all gone. I "solved" my problem the
stupid way by rebooting the router and lowering the DHCP timeout from
24 to 3 hours.
A production script would be clever about resetting it only on new
associations, and not on every brief reassociation. However, still
something to keep in mind when deploying networks that encourage this
sort of thing. ;)
Hi!
I remember you had some discussion about how to flash routers. I think
there are several options:
- having a generic firmware you configure by hand/webinterface
- having a image generator which generates image with all configuration
included for a particular node
- having an generic autoconfiguring firmware, which
- does everything by itself
- optionally fetches additional/configuration data from the
network/central server
- registers at first boot with networks/central server
Am I missing any?
Some possible relevant links for flashing and ideas:
- https://github.com/battlemesh/openwrt-config-system
- https://dev.wlan-si.net/ticket/1135
- https://dev.wlan-si.net/ticket/654
- https://dev.wlan-si.net/ticket/1153
Some ideas we were playing around as well:
- a phone app which you install, connect to the existing original
wireless network of the node you want to flash, press a button and it
flashes
- entering your public IP of your home router you want to flash and some
server flashes the node for you over the Internet

hey guys n gals,
I just discovered your mesh project, and I'd like to contribute somehow.
Are you still in need of hardware?

What would be most useful?

The attachments are of particular interest to the history of WiFi efforts in Oakland and the political economy surrounding the different initiatives.
Deborah Acosta, as many know, is now the Chief Innovation Officer of San Leandro.
There are also some documents that are not for public distribution outlining how things fell apart within the Oakland municipal government.

I’ve attached a City RFP issued in 2006, the final report issued by the consultant and the final staff report that resulted from four years of work on the city wide wi-fi project. The stories I could tell you. Ultimately, the report found that the City’s fiber infrastructure was inadequate to implement such a project – and the City Council didn’t “get it” anyway.

No one has picked up this project since I left.

i got openandnotorious.org to map out abandoned and foreclosed properties, where nodes placed in these locations would turn into a legally recognized easement surviving new owners after 5 years under California law under the doctrine of adverse possession (for easements). The legal requirements for possession during this period include other factors, but the main ones are that the use be open and notorious. While proving that may otherwise be difficult, being listed on openandnotorious.org would solidify the presumption.

I even took him through the 5-year adverse possession plan to get easement property rights to keep them there permanently. He was intrigued and most importantly gave a strong indication that he would like to support our efforts and particularly in helping create the backbone across Oakland that would facilitate mesh networks. As a first step, he suggested that we map out 25 or so of the taller buildings around the city that would allow us to put some antennae equipment on their roofs.

All,
I am driving up from Los Angeles Friday morning and will be coming to the Saturday evening hackathon.
Would love to meet up with as many folks as possible and help build up the FNF and PeoplesOpen relationship even more.
See you all Friday/Saturday.

Hi, I just joined the list and have been exploring the relevant web pages.
I'm excited to get involved -- I first encountered the idea of community
mesh networks at the early meetings of Personal Telco in Portland when
802.11b was just starting to become widespread, and have been hoping to
have a chance to participate in something like this ever since.
I'm at 32nd and Adeline (node "phorzaith"), and from consulting the node
map I think I may have decent line of sight to tunabanana and TSA, a little
more than half a kilometer down Adeline St. and across the street; and
maybe even Hearth. (woody and OMI are also close, but I think line of sight
would be difficult.) I have a first floor apartment, which isn't ideal, but
I might be able to work with neighbors upstairs or a couple doors down to
get better antenna position. I have questions about mounting a router vs.
just mounting the antenna -- anything in my front yard and positioned to
reach that far down the street would, I think, be at risk of theft. I'd be
happy to donate a portion of my Internet bandwidth, provided that I have
the ability to turn it off temporarily on occasion -- my DSL connection
maxes out at about 3Mbps down and 1Mbps up.
I'm going to try to attend the meetup tomorrow. Unfortunately Thursday
nights are bad for me, so I can't usually do in person stuff. If anybody
has specific stuff to point me toward to read or think about before the
meetup, please do!
Pete
