44.103/16 Coordinator Request
by Fredric Moses 11 Mar '18

11 Mar '18

Hello, I am wondering if there is a way we can take over as the coordinator for the 44.103/16 Michigan2 Block. Currently all the allocations in this /16 are to our microwave projects here in Michigan and it seems there is an issue with requesting a /24 that will be BGP announced from a separate location then our current allocations. I made a request on 2018-02-07 the coordinator requested I submit a utilization for one of our /19’s. We currently have a /19 /21 /23 /24 in our project now but I responded with the /19’s utilization report as requested. On 2018-02-14 the coordinator responded with : Fred, Your request will be ready RSN (Real Soon Now) I said thanks. On 2018-03-01 I asked for a status update. 2018-03-03 the coordinator responded: I expect next week. That week has now come and gone with no response or allocation. If a coordinator can not be changed out we would be willing to re-ip into a new /16 block that we can issue requests for IP’s in a more timely matter like our HamWAN brothers do out in the western US area. -- Fredric Moses - W8FSM - WQOG498 fred(a)moses.bz

Hi, to all concerned, found the following errors by making the 'source' of the actual 'encap.txt' file. Can't add route to 44.24.172.40/29 via encap 44.24.172.41 Can't add route to 44.130.104/24 via encap 44.130.104.1 Can't add route to 44.130.105/24 via encap 44.130.105.1 Can't add route to 44.130.106/24 via encap 44.130.106.1 Can't add route to 44.130.107/24 via encap 44.130.107.1 Can't add route to 44.131.14.252/31 via encap 44.131.14.253 Can't add route to 44.136.150/23 via encap 44.136.150.2 -- 73 and ciao, gus i0ojj/ir0aab

Re: [44net] TNC for Raspberry pi that support 9600 Baud ?
by Rob Janssen 09 Mar '18

> At minimum, just a USB sound card ($5 US) and some way to key up your > radio. The Direwolf UserGuide details all this for you. On a Raspberry > Pi, a simple transistor circuit and a GPIO pin off the Pi is all you need. For software guys, it is now possible to make receive-only installations with even less hardware. On our co-channel diversity repeater system we have sites where an RTL DVB-T stick is used with SVXlink "remotetrx" configured to provide a number of virtual NBFM receivers where some of them are connected to the SVXlink master site to receive voice to be transmitted over the repeater, and other virtual receivers are connected via a loopback audio device to a direwolf process used to gateway the received APRS packets to the aprs2.net As the APRS frequency on 70cm is in the process of being changed, we receive on both the old and new frequency and also on 2 different repeater input frequencies, all with a single stick (and a bandpass in front of it, of course). I have even tested an SSB input to the repeater, which worked fine too. It is possible to add receivers and connect them to some application without touching the soldering iron, without even going to the site. It is really wonderful what software can do today... Rob

White space radio
by Steve L 06 Mar '18

06 Mar '18

This radio will be field tested soon at an area school. I look forward to hearing more and will report back when I do: http://www.metricsystems.com/ I figured I'd point it out to the list enough though I suspect the price point is not for the typical radio amateur. It would seem a company making such a thing would have a limited market, so if it could be unlocked to cover ham freq's that might provide a small secondary market. Either way, hams looking to move data might also want to research white space radios as I suspect this sort of thing will be more common. PS: I see the dunderheads in Newington have proposed some changes to the hobby. Sadly anything to do with data/bandwidth isn't part of it.

FYI 73, Ruben - ON3RVH From: Bart Cretskens [mailto:bart.cretskens@gmail.com] Sent: maandag 5 maart 2018 13:39 To: Ruben ON3RVH <on3rvh(a)on3rvh.be> Subject: Re: Allocation request ON5BAC Dag Ruben, Sorry, inderdaad, je hebt gelijk, een /29 is goed om mee te starten. Alvast bedankt 73e Bart 2018-03-05 9:23 GMT+01:00 Ruben ON3RVH <on3rvh(a)on3rvh.be<mailto:on3rvh@on3rvh.be>>: Dag Bart, Kan je ons meer detail verschaffen over waarom een /24 aub? Standaard staan we enkel /29 size netwerken toe, dit om het verkwisten van IP adressen te vermijden. Een /24 staan we enkel toe als je zelf de BGP routering naar het internet ervan kan doen. Dus dan heb je een ASN nodig en minstens 2 transit providers die bereid zijn om die /24 voor jou te announcen Alvast bedankt. 73, Ruben - ON3RVH Member of the AMPR ON0 coordinations team

DMR trafic behave on AmprNet
by R P 02 Mar '18

02 Mar '18

About a year and a half ago I have asked how good will be the AmprNet to use to connect DMR repeaters So finaly i have made a HotSpot and connected it to the AmprNet and it connect to our Server via the AmprNet I use tunnel to UCSD and not BGP so traffic travel to UCSD The results are impressive No problem at all although the latency is big no words loose or packet loss The only thing i see is a bit delay until the Hotspot start to transmit and this is (probably ) because the latency so the PTT command delay a bit It is a high power hotspot consist of a 25 Watt radio connected to a MMDVM system so users use it and i didnt get any complain of any disconnection or any issue of networking or service so far If you are interested the statistic of the MikroTik Router that handle the AmprNet traffic show about 12Kbit/Sec UDP when the data flow from the hotspot to the server Ronen - 4Z4ZQ http://www.ronen.org Ronen Pinchooks (4Z4ZQ) WebSite<http://www.ronen.org/> www.ronen.org ronen.org (Ronen Pinchooks (4Z4ZQ) WebSite) is hosted by domainavenue.com

Routing of 44.0.0.0/8 how are routes announced to users?
by Benoit Panizzon 26 Feb '18

26 Feb '18

Dear List I'm pretty newly connected to hamnet, and also work at an ISP. I always assumed 44.0.0.0/8 would not be announced to the internet, but only routed privately on hamnet. Now I see routing issues I don't quite understand as for me this looks like routing is completely broken... On the internet core router I see that 44.0.0.0/8 is being announced by AS7377 (UCSD). But IP Addresses from the swiss HamNet range are not reachable via AS7377. So what is the point announcing the whole range to the internet? There is no 'more specific' route to 44.142.200.1 On the other hand I cannot reach parts of hamnet via hamnet. Take for example the Primary DNS of ampr.org: ampr.org. 3600 IN SOA ampr.org. ampr.org has address 44.0.0.1 1 gateway (157.161.57.65) 2.947 ms 2.887 ms 2.847 ms 2 mikrotik-hamnet.woody.ch (192.168.57.243) 4.937 ms 4.920 ms 4.887 ms 3 rf0.am-32.hb9am.ch.ampr.org (44.142.162.97) 21.810 ms 24.858 ms 29.860 ms 4 bb-hb9am-30.db0wbd.ch.ampr.org (44.224.90.81) 29.847 ms 32.792 ms 32.771 ms 5 wan-db0wbd.hc.r1.ampr.org (44.148.240.45) 78.907 ms 81.925 ms 84.438 ms 6 dc1-dc2.hc.r1.ampr.org (44.148.255.253) 97.808 ms 98.107 ms 113.973 ms 7 wan-db0gw.db0fhn.ch.ampr.org (44.224.122.2) 113.986 ms 113.149 ms 118.384 ms 8 db0fhn.ch.ampr.org (44.130.60.100) 126.890 ms 118.628 ms 137.776 ms 9 * * * My Gateway has a default route to the internet and a static route for 44.0.0.0/8 pointing to my WLAN Link to a 'public' Hamnet AP. So what is the point of having sort of a split-brain situation on the 44.0.0.0/8 hamnet ip range? I 'see' ospf packets on the WLAN link, but they only seem announce the local routes withing the swiss part of hamnet, not the global routes. Sort of makes sense, as you probably would run bgp to interconnect the different hamnet as numbers. So do I need to get an own hamnet as number? As a User?!? Or what mechanism is there supposed to be to tell a user which hamnet ip ranges are reachable via internet and which ones are reachable via hamnet. 73 -Benoit- / HB9EUE

Anyone running an open AMPR VPN willing to share?
by David Ranch 17 Feb '18

17 Feb '18

Hello Everyone, I'm helping out a local HAM getting an IPIP AMPR setup working but his current AT&T Uverse / Pace s 5862ac unit doesn't seem to be playing nicely. Yeah.. I know.. Shocking! Anyway, touter/NAT mode seems to *only* want to forward TCP/UDP protocols (typical) and it's DMZPlus feature mode seems to be breaking his Wifi network. As we maybe hack with the DMZplus feature tomorrow, I was curious if there is anyone willing to offer up a VPN connection to his Raspberry Pi as a Plab-B: Looking through the archives, there was http://wiki.ampr.org/index.php/AMPRNet_VPN but that link is 404. I know there is also the http://wiki.ampr.org/wiki/AMPRNet_VPN link but I know other HAMs are/were offering less complicated setups. I can help him setup any offering be it IPSEC, SSL-VPN, etc. He's not looking for any sort of performance.. just general IPIP access to play around, etc. at the moment. If already hosting or you're willing to host a solution, let me know. Thanks! --David KI6ZHD
