Inviting you to ARDC Grantmaking Survey + Community Jitsi Call

by Rosy Wolfe

Hello 44net! Hope you are healthy and well wherever you are. I'm writing to invite you to a couple of things. 1. ARDC Grantmaking Survey The first is an invitation to take this survey about ARDC grant making, which you can find here: https://www.mysurveygizmo.com/s3/5789610/ARDC-Grantmaking-Feedback-Survey The survey covers our existing granting goals and some of the kinds of projects that we've funded so far. What do you think? What other grants would you like to see? Do you know of organizations, either in the US or abroad, that you'd like to see us fund? Let us know - it shouldn't take more than 5 minutes, more if you decide to give some longer written-out answers. 2. 44net + ARDC Community Video Call We'll go over the results together in a community video call, happening Saturday Oct. 10, 2020, at 17:00 UTC (10am PT / 1pm ET / 6pm BST / 7pm CEST). On this call, we'll introduce ARDC Board members, grants advisory committee members, and staff; go over the survey results together; talk about our grants made to date; and talk about any questions you have. If there's anything in particular you'd like ARDC to cover in the call, please let us know by responding to this mail or sending me a message directly: rosy(a)ampr.org. Here is the link to the call: https://meet.jit.si/ardc-44net-community-meeting-oct-10-2020 A note on the times: I realize that the times listed are more convenient for folks in the Americas, Africa, and Europe. If enough people from Asia and Australia wish to join but can't for timing reasons, we may do another group call for those time zones. Part of this exercise is also learning about 44net's distribution - where is everyone located? I'm looking forward to finding out. I'm also looking forward to better getting to know 44net and the greater ham community, and to use what I learn to help shape ARDC's 2021 grantmaking strategy. We are in a fortunate position to do a lot of good in the world - so let's do it! All the best, Rosy -- Rosy Wolfe Executive Director Amateur Radio Digital Communications (ARDC) ampr.org

GL.iNet openWRT Rip44 support?

by Tracy Markham

I had reached out to the good people at GL.iNet and asked for help getting one of their openWRT routers to run my 44 net assignment. I referred them to the page explaining openWRT setup ( wiki.ampr.org/wiki/Setting_up_a_gateway_on_OpenWRT) and requested they compile an executable for the processor in the router. Apparently they did it. It will be a bit before I can try to configure it but its a one click installation. It's available to anyone with a GL.iNet router product, just navigate to Applications -> Plugins and Update, then navigate to the R section. I have a screencap of all the dependencies it installed if anyone is interested. I reached out to them because I've failed on my previous attempts to set up an EdgerouterX for my assignment... I am by no means a network engineer, this is my foray into getting a gateway going. If anyone could confirm this works that would be great. If you're willing to help me get mine going that would be even better. Tracy N4LGH

Network topology and vpn connection.

by pete M

Hi! First I want to thanks the ampr group and especially G1FEF for providing me a /24 that I am in the process of being bgp annonce with a vultr vps in NJ. If what I am about to talk dont fit in the group, please let me know, I will move this else where. I am in no mean a network guru but I understand concept pretty easily. SO I am planning my /24 as this. the VPS at vultr will use Bird to annonce the route, I will use only the default route provided by vultr. >From there I created a dummy interface that have my /24 as its IP. I then want to make a VPN server to distribute the net and ip to remote site I have that use a mix of hardwired and wireless connection. The routers are all edgerouter-x from ubiquity they will all eventually be interconnected by 2 sources, the hardwired provided by many ISP and the wireless that I am building as a redundancy. If one sources fail, the router will fall back to the other link. the prefered links will always be the hardwired, the wireless is the backup. (some of the links are 40 Km long, but most are 5-6 Km and the smallest is under 1 Km.) >From those edge router I will have connection to the vpn and every router will have a dhcp server that will serve a part or the /24 like 16 ip for each site. (I have 3 site right now) and I will have fixed IP at each site for the repeaters and aprs gateways. Now the configuration of the vpn is my first problem. should I have the vpn server listening on the ipv4 address of vultr or should I made it listen to the dummy interface? I think this is juste the beginning of my quest! Pierre VE2PF

How long for attribution of a ip segment?

by pete M

Hi! I asked a few months ago for a /24 so I could advertise it by BGP on a vultr server. I had receive a request to fill up a form, but for personal reason I was not able to pursue the project. rewind to end of september and I redo the request, fill out the form and do everything in order, well I hope, but it was delayed cause the emails I was receiving kept going into the spam folder.. Sent a few email back to ask the status, if my form was filled ok, I had no answer. I am just wondering if I did something wrong or if the request is en route. Sorry if this is the wrong forum to ask. Pierre VE2PF

Re: [44net] Thanks to everyone for a good 44net community call!

by Rob Janssen

> Is the European Asterisk/DUNDI/AMPRNet voip network you describe below documented somewhere? I tried to google around but did not find anything. There is some scattered information, e.g. this at DB0WA: https://www.afu.rwth-aachen.de/projekte/hamnet/anwendungen/sip-telefonie https://www.afu.rwth-aachen.de/projekte/hamnet/infos-fuer-betreiber/dundi-n… This page also describes a crawler for such nodes and shows a map, but I think this crawler is dead as the map shows information from last year and has not been updated since. That is probably related to the renumbering of the German/Austrian network. (as you know these networks ended up being in the part that was sold) I don't know if the network itself is still actively maintained or if it is just an experiment that is not interesting to its inventers anymore and just keeps running until the servers crash, someone turns them off, or a disruption such as the renumbering occurs. At least locally for me it works fine, but I use it mainly for calls to one other person who is on the same PBX as I am. Rob

> If you're offering to organize, create and open-source a conferencing > system that does what Zoom does AND SCALES UP, be my guest! You could > even apply to us for a grant... I don't know how wide its coverage is, but here in Europe we have a network of Asterisk PABXes on AMPRnet that have interconnecting trunks between them that allow you to call anyone on the network on their roaming number. Phone numbers are allocated based on the callsign (using a scheme based on the letters printed on DTMF keypads. based on my callsign, my phone number is 713210234253 for "1st letter on key 7, 2nd letter on key 3, digit 1, 3rd letter on key 2, 2nd letter on key 4, 3rd letter on key 5" giving PE1CHL ). The DUNDi trunk protocol distributes the information about the home server for each number across the network, so all Asterisk servers know how to route the calls. It is easy to host a conference on one or more of the Asterisk servers and have everyone dial in to that. There is such a conference running on my local server where I have my IP phone connected all the time. I think such systems can do low-bandwidth video as well, but I have never tried that. For audio it works perfectly. > Seriously, this touches on one of my pet topics: IP multicasting.

I agree that would be much more efficient than having the basic star-type structure where everyone gets the same stream from one server. That would be one thing that could be implemented in AMPRnet to show the world that it really has advantages. For phone quality voice and the number of attendees we would expect, running this over AMPRnet in the star configuration should be no issue. Rob

HNAP4PlutoSDR - HAMNET on 70cm with the PlutoSDR

by Jann Traschewski

Hello AMPRNet, we like to announce a new open source HAMNET-access solution for the 70-cm-band making use of the popular ADALM Pluto SDR. Lukas Ostendorf recently finished his master thesis "Design of a Radio Communications Protocol for HAMNET Access in the 70cm Amateur Radio Band" at our employer Rohde & Schwarz in Munich. We are pleased to publish his work and further material today: https://hnap.de/2020/09/08/master-thesis-released.html There are still some tasks like signal amplification on the roadmap, but the community is growing and helping to move on. It seems the telegram group chat is currently the best place to exchange: https://t.me/hamnet_access_protocol Most communication is in German, however I'm pretty sure English is fine as well. At least you will find nice pictures of current experiments in the backlog :) Looking forward to your contribution, for the HNAP-Team, Jann DG8NGN -- Jann Traschewski, Faber-Castell-Str. 9, D-90522 Oberasbach, Germany Tel.: +49-911-99946898, Mobile: +49-170-1045937, E-Mail: jann(a)gmx.de Ham: DG8NGN / DB0VOX / DB0FOX / DB0ZM / DB0DBA / DB0HZS

> Mikrotik is the only one among cheaper gear to have a PIM (only Sparse mode) implementation. It is a bit clumsy but with a few tweaks it is (from my experience so far) manageable. Do you have a description somewhere how you set it up in a 44Net network? We have a national network over here with many (mostly) MikroTik routers linked by radio links and VPNs. It could be an interesting experiment... Rob
