Hi, I'd like to get some stickers and t-shirts printed :) t-shirts could be sold for a significant chunk of the cost of a node. and stickers can go on routers, folks' laptops, window of business running a mesh node, etc. What do folks think? --mark B.

Mesh hardware has arrived!

by Marc Juul

Hi folks. The $2000 mesh hardware has arrived. Jenny and myself have spent the evening going through everything and making an inventory of what we have, what we need to get everything into working order and how much appears to work. We did a power-on test of all hardware (except the AirGrids which are weird and don't connect them to anything unless you know what you're doing or they'll fry!). The summary is that, we have the following working outdoor gear at our disposal: *15 nice big 2.4 … [View More]

batman-adv README

by Miguel Vargas

Hi guys, Here is the README file I kept mentioning last night, https://www.open-mesh.org/projects/batman-adv/repository/revisions/master/e… It gives a simple explanation of batam-adv configuration without getting into batctl, just the config files. The interesting piece is that you need to provide an IP address to the bat0 interface. The idea is that all the bat0 interfaces in the network together act like a Layer 2 LAN. And just like a LAN you need to provide an IP address on the same … [View More]subnet to each interface in order for any packet routing to happen. This is a problem for our idea of having a standard image that we can flash onto all routers since each router will have to have individual configuration. The standard solution for assigning IP addresses in a network is to use DHCP, but that is a problem because 1) we don't want any central control, 2) the network will probably end up being segmented into clusters that don't talk to each other. I was thinking one idea for assigning IP addresses could be to use IPv6 and map the interface's MAC address onto it, we could then have a configuration script to configure the address. But it turns out that this kind of thing is built into the IPv6 protocol [1] . This seems to be what the Quickstart guide is talking about when it says "You can now use the automatically assigned IPv6 link-local adresses on bat0 (usually starting with fe80::...), modern operating systems should support this." [2], although when I followed the guide I didn't see any auto-configured IPv6 address. I'm not very familiar with IPv6, I need to learn a lot more. Another issue with batman-adv being a pure Layer 2 protocol is that there needs to be some kind of Layer 3 routing protocol used on top of it in order to direct packets to where they need to go. It turns out that batman-adv has implemented such a thing as an optional 'gateway' feature. The gateway documentation is interesting because it seems to show some of the controversy generated around their philosophy of having a "clean network layer separation" [3]. This gateway feature piggybacks on DHCP, which has the problems I mentioned above. Anyway, we need to keep reading and testing, there is a lot for us to learn. It might be that we decide that batman-adv isn't the right choice for the network we want to build, I think last night was great for getting us towards making that decision. Though I think it's important for us to develop a stronger vision for what it is that we do want to build. Happy hacking.

Re: [Mesh] [sudo-discuss] Router Reuse Donation Drive

Jenny, that was an exquisitely written solicitation. Is "metamycelia" an allusion to *Avatar*? It conjures up an image of dense fungi radiating vegetative consciousness! More pragmatically, I have a question for you and Marina: Do either of you remember seeing any wireless routers among the mounds of equipment at OTXW?

The cheap USB sticks don't go above 64 mHz *Trying to find a cheap transmitter that can do more than 9600 baud *APRS weather stations and some ham operators are already operating at that level **NarrowBandFM – use with 50 watt transmitters (5600?) **GPS transmits position, with repeaters operated by amateurs until it reaches an internet gateway in Finland which has a map **not very disaster proof, only 1200 baud *>1mbps OFDM (orthogonal frequency division multiplexing, similar to CDMA) modulation, which is also used for wifi – spread spectrum technique that uses frequencies which are orthogonal, so you won't get any noise from the adjacent channels (less interference) *<$150 transmitter *can be tuned into legal frequencies later *“ssh is the first thing i'd want in an emergency' *→ but most nodes are just going to be receivers *49 mHz, kind of abandoned territory – 49 is analog - *transmit-capable SDR on new 4G devices *build the transmitter, and use the audio port – seeking to design that =relaychum: friend-to-friend darknet= *https://github.com/substack/relaychum *every message goes to every node, but the senders are completely anonymous (as are the recipients), *still needs crypto and signing, then a mailbox system *indexdb: permanent storage in a browser *compensates even on a crappy network *once back online, can propagate out to the network *written in node.js *partition-tolerant darknet *public keys from chums *chum rings! and also bigger rings *every node is relaying traffic, so the identity of the originator can't be traced *liquid chat room *inspired by homestuck comic - 'pesterchum' *creating a trust network *by writing it in node it can also run in browsers *pushing out public keys to the network **don't want that information contained in the key itself **could hash the keys *=Funding=* *What are our costs? *Routers, minimum specs: **4MB+ & OpenWRT compatible **check seattle meshnet wiki for hardware specs *Router donation drive *Which protocol? **batman-adv vs babel vs. cjdns **open-mesh.org – has the documentation for batman **Babel seems easier **Still need to play with cjdns *Captive portal *Serving less than 1kb locally =Rad Routers= *WRT54G – rev 2 (NOT rev 3 or 4) *Asus RT n10+ series routers are highly reliable *WR703N router – half watt routers =Divergence into political philosophy= *“the whole stupid is greater than the sum of its stupids” *amplification of the spectacle *the best response is finding alternatives to fear – eg joyful emotion and communitas *the generative internet rather than walled, open architecture & decentralized human and machine apis *digital citizenship movement *redefining the commons *revived calia proposal *destabilizing foreign governments does go hand in hand with CISPA-type proposals *Border routers in Australia =Action Items= *Meshathon! (future event) **Get 3 routers and get them talking to each other. **Setting up a tiny mesh can take less than 4 hours *David Gothberg talk, “Peer-to-peer Under the Hood”: http://www.youtube.com/watch?v=MNzMNjW8oGs *Awesome Foundation proposal to fund initial hardware *Everyone should buy a router (or several) for themselves to play with =Next Meeting= *Thursday, 5/16, 6pm @ sudo room *Playing with new routers, installing OpenWRT and possibly batman-adv, babel [View Less]

TIER - Technology and Infrastructure for Emerging Regions

by Jenny Ryan

For work I've been advising a group in India who are working to bring internet connectivity to rural villages. Finding our little R&D project quite helpful in the process! In looking for mesh projects in India, I came across the Dharamsala Community Mesh project<http://www.docstoc.com/docs/143451940/The-Dharamsala-Community-Wireless-Mes…>, assisted by a group at Berkeley called TIER. Good stuff here: http://tier.cs.berkeley.edu/drupal/ See y'all tomorrow at 8:30! Jenny http://… [View More]
