Hi All, I live in portland OR, and I am just recently getting interested in wireless meshnets. My current setup is two nodes, Raspberry Pi 2 Hardware, one with a tp-link TL-WN722N, and the other with some sort of "panda wireless-n" adapter. My problem is that I am getting around 30% dropped packets, and they are about a foot apart, which makes me wonder if using a ad-hoc is a good idea or not... I have them both running Ubuntu 14.04 <https://wiki.ubuntu.com/ARM/RaspberryPi> and the most recent version of cjdns. My network configs are below: root@ubuntu:~# cat /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet dhcp auto wlan0 allow-hotplug wlan0 iface wlan0 inet manual wireless-channel 8 wireless-essid NeighborMesh wireless-mode ad-hoc So then I decided to just remove the wireless usb adapters, and run cjdns over the eth0 interfaces, but I am still getting a consistent ~12% packet drop with that: --- fcfe:307d:38e5:5aa4:9bfc:a4ce:dd3d:969c ping statistics --- 76 packets transmitted, 67 received, 11% packet loss, time 75156ms rtt min/avg/max/mdev = 2.378/26.382/196.791/51.318 ms Pinging the IPv4 address outside of cjdns works great, always: --- 192.168.0.226 ping statistics --- 24 packets transmitted, 24 received, 0% packet loss, time 23002ms rtt min/avg/max/mdev = 0.640/0.675/0.783/0.036 ms What am I doing wrong? I *would* like to achieve standalone/independent wireless mesh nodes that dont need a master access point to function. (I am imagining giving one to my geek neighbor, and seeing if we can start a mini mesh network) Does anyone have any suggestions? -Cobin

Looking for someone that would hold my hand and...

by danarauz＠gmail.com

I know the subject line is like.. woot!?? :) But seriously... :) I am looking for someone to hold my hand and walk me through (help me with) a couple of small projects. Here is what I wish to accomplish: 1- to get a router with OpenWRT (Not sure of its capabilities, but I like the idea to get ride of the corporate code, because potential backdoors) 2- and if needed, a tiny computer that would be always connected to a VPN account, so that all home computers can use it as their gateway; IF the router cannot do this. What can I give in exchange? Well, I don't know what knowledge I can share when all of you seem to be way above my head. I don't know, maybe Photography? Spanish? :) Please let me know if interested, we can start right away. I am eager to start this.

Late, but coming eventually!

by max b

Hey so I'm super late, but I am definitely coming (I got sucked into watching a basketball game!) I did call these folks today: http://www.hamradio.com/locations.cfm?storeid=3 I asked about non-penetrating mounts and they mentioned that they have "tripods". I know that's not really what we were thinking about, but I think it'll be worth it for me to swing by tomorrow and take a look. I'll drive, so if anyone else is interested in swinging by, let me know. Probably around 2:30 or so... On other notes: - What are people's thoughts about new payment processing solutions? We've gotten some notices from gratipay that they've fixed their issues, but that we'll have to re-apply as a "team". We *could* roll our own stripe system, but in my experience using stripe to charge credit cards is easy, but properly managing recurring payments is not that easy. I personally would prefer to continue to allow a third-party to do that work. Does anyone know what sudoroom is doing? - The sudomesh.org server (and peoplesopen.net and all the other stuff) is slowly being brought back to life. I believe that @sudomesh.org (and @ peoplesopen.net) email addresses are currently down, so it might make sense for us to fix that first before we apply at gratipay again. I have purchased a digital ocean VPS, so the next step is to finish setting it up and then coordinate with marc on DNS settings. - Node mounting this sunday? Of course, if we get the non-penetrating mount, we can set up a link between Will and the Omni. Even if we don't get the non-penetrating mount, there's plenty to be done. We need to run cable (not a simple feat to do correctly), configure a mesh node tp-link or mynet, configure extender node antennas, and create a link between them (we can just do it by holding up a radio on the omni side by hand). Who would be around to do some of this? Will is on this list, but I might get in touch with him off-list anyhow to see if he'll be around and would be interested.

A survey of community network management solutions

by Mitar

Hi! Please help us fill in the spreadsheet of community network management solutions out there. We filled in those we know about, but even those only partially. So if in your network you are using some solutions for network management, please fill it in: https://goo.gl/JbD4VC As we are working on nodewatcher v3 we are trying to keep up with developments of others. We will also use this data in the paper we are writing about managing community networks. Feel free to use the data as well. If you strongly feel that some column is missing, add it, but remember that it has to be filled for all rows to be really useful. Spreadsheet is CC0.

Re: [Mesh] Fun, installing mesh - Also: Special Attn April Glaser

by pansophia

While this is something I couldn't participate in, I hope hanging out helps me learn more about it. Perhaps next time I can help with something that can be done down at the table such as adjust the routers? I'm the one with questions about whether it is possible (or even wise) to build local political relationships to boost local library wifi out into surrounding neighborhoods. Then Mesh concepts could be used from there. I ask because I see an opening to develop that kind of relationship and ask for civic space goods in South Berkeley. The City is sidling up to us because they need to show they worked with the community when they apply for big Federal transportation grants later. Matt and Jenny brought up some concerns about using libraries as signal sources: 1) Library workers are unionized and will object to putting Mesh software on their computers. They have a select set of software they have agreed to maintain. Software conflicts may cause unanticipated conflicts and create extra work for them. 2) Libraries block some content. 3) Libraries turn off their wifi when they close, and their hours may change according to city budget. I've had some fantastic opportunities lately to pursue the "boosting library wifi" idea, but I want to make sure this is a good thing to pursue before I do. The impression I got from a chat with Jenny yesterday is Mesh just wasn't ready to work with the library scenario yet, but there was no legal/political problem with discussing it. The chorus of advice is to "bring it up with April!" I did have a really sweet opportunity on Saturday to bring Mesh up with my Council Member, and in the current situation it's possible those opportunities might come up a few more times. I'd welcome any guidance about what to do (or NOT to do) on such occasions. ~ Elisa On Mon, Jun 15, 2015 at 3:31 AM, Marc Juul <juul(a)labitat.dk> wrote: > > > On Mon, Jun 15, 2015 at 2:25 AM, Tom <tomwrites326(a)gmail.com> wrote: > >> Hi Sudo meshers, >> >> I had a great time helping install the Ethernet with you and wanted to >> thank everyone for such a fun day today.

Access control: BBB PoE?

by David Keenan

Hi all, As it seems some Ethernet runs are planned for today, I was thinking about power distribution also for the Beagle Bone Blacks (maybe not Blacks but anyhow) recc'd by Marc to control electronic access at each door needing it. Stringing extension cords & wall warts from ea. BBB - door set is both not code-worthy (if an inspector really wanted to bust our balls since 'permanent' extension cords are called out), multiple AC>DC conversion is also power-inefficient, prone to power loss/unplugging & and may require further electrical work to bring outlets closer to some doors.. Since I understood that BBB's don't accept Power over Ethernet (PoE) I was considering central low-voltage power distribution through a single Variac-type DC power supply, DC PDU, PowerPole connectors and the zipline of appropriate gauge for the runs to deliver ~5VDC at the BBB endpoints (I have done this before). However (even if it is not as power-efficient) if we are injecting at Sudo's racks it seems we could use Ethernet for power if we inject 12VDC PoE, then break it out at the end to a cheap 12>5VDC adapter which could in turn feed the 5VDC port on the BBB's - check out the last post of: https://groups.google.com/forum/m/#!topic/beagleboard/nrRZJkCWQa0 If we're running the thicker-gauge pairs in cat6 (compared to Cat5(e)), we might be able to get away with 5VDC injectors but probably the injection point would have to be more centralized within the building than the racks in sudo room - like in the basement furnace room e.g., which makes most sense to me as the central distribution point for Ethernet runs around the building, due to it's centrality, the ease of running into/along ducting/registers, proximity to the basement, perimeter crawlspaces, the ease of lateral runs through the basement, etc. Love David

Reminder: Omni Wifi installation tomorrow (Sunday)!

by Marc Juul

We're running ethernet cable and installing wifi routers at Omni tomorrow at 1 pm! We're low on hammers, so bring one if you can. We will need them to attach cable clip nails. If you have a really long drill bit for punching through walls that might come in handy. I'm not sure we'll need it (most walls at Omni are very thin), but if you have one bring it! also bring snacks/drinks if you can (caffeine > alcohol) I will try to brew some (non-carbonated) sudo mate :) hack hack hack! -- marc/juul

Mesh meet BBQ and a movie?

by Marc Juul

I got a propane BBQ yesterday and I want to try it out! Today (Tuesday) isn't going to be quite as warm as yesterday, at least not in the evening, so how's about we meet at my place in West Oakland, at 6 pm (before it gets cold and dark) with our laptops and some stuff to throw on the barbie and then head to the New Parkway to watch Ex Machina? http://thenewparkway.com/ https://en.wikipedia.org/wiki/Ex_Machina_%28film%29 Good idea? Bad idea? ( i'm in the mood for celebrating a bit since the CCL kickstarter just reached its goal :) -- marc/juul
