<p>Actually I first ordered Pittmesh's lower-priced, unmodified Gl-Inet,
the A150. My rationale was that if Pittmesh didn't work out, we
could always flash it with Stuart's configuration later on. <br>
</p>
<p>However they were out of stock of that item and sent me the A<b>P</b>150
for the same price, so I kept it. Nick: The AP150 is already
weatherproof, it has gasket seals. That may be the whole point, a
GL-Inet repackaged for outdoor use. <br>
</p>
<p>I didn't realize OLSR is limited to IP4. Well learning new
things is what I paid for. <br>

What is ssb-dns? Also what is an insns? Thanks... <br>

<div>Niiiice. Still need to get one of these little guys.
This is basically my dream of a little outdoor mesh node.

Hardware wise, the AP150 is the same as the unit I picked from
Gl.inet. Their mesh protocol is <a moz-do-not-send="true"
href="http://olsr.org/">OLSR</a> which has a user space daemon
attempting to track the graph of the mesh and dynamically
adjusting the kernel routing table accordingly. It also only
works with IP4.<br>
<br>
So I want to use the BATMAN-ADV protocol, which does not need to
track the mesh graph. Nodes broadcast a "Hi! My name is ..."
packet every so often, which can take multiple routes to each
other node (there is no attempt to prevent duplication, only loops
in the broadcast). The one that arrives first determines the
"next hop" route for that destination (as it is the fastest by
demonstration). Subsequent arrivals are ignored (preventing said
loops). Batman creates a virtual bridge device - which can bridge
many different interfaces - hence allowing multi-modal
communication on the mesh. <br>
<br>
For clear IP6 on the mesh itself, the routers can all announce a
fixed fd00/8 prefix - no central coordination required. If people
really want IP4, we'll have to have a central authority handing
out 10.0.0.0/8 subnets to anyone wanting to run a DHCP server.
There are 65536 /24 subnets in 10.0.0.0/8. Cjdns of course
requires no central coordination.<br>
<br>
For DNS, we can avoid centralization (at the cost of giving up
guaranteed global consistency) by using ssb-dns. But so far,
getting people on ssb has been as difficult as getting them to run
their own DNS server. I don't thing the routers will run
scuttlebot - DNS gateways for ssb-dns will have to be on something
a little bigger. Even an rpi0 should be able to handle it (I'll
be testing at some point).<br>
<br>
My batman routers also "just work" (the one that didn't at a
recent meetup had been reprogrammed for an experiment with trying
to use CoxWifi to carry batman packets - nope, the Cox routers
block them just like the library). OLSR could run if Cox/library
allow UDP broadcast. There also need to be some standard WAPs for
android/windows/apple to connect via Wifi. This just occurred to
me (yeah, duh!). I don't need to reinvent that wheel - the batman
routers just need to bridge the LAN port to the mesh.<br>
<br>
Looking at the Pittmesh AP150 - it is a different brand from the
GL-inet ar150, and from the manual configuration insns, it looks
like they are openwrt and you can install batman instead or OLSR.
We should see if they support better adhoc data rates.<br>
