Inviting you to ARDC Grantmaking Survey + Community Jitsi Call
by Rosy Wolfe 12 Mar '21

12 Mar '21

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 30 Dec '20

30 Dec '20

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

HNAP4PlutoSDR - HAMNET on 70cm with the PlutoSDR
by Jann Traschewski 15 Oct '20

15 Oct '20

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

27 Sep '20

Good evening, it's been a while since I had to add/change/delete DNS entries in the ampr.org DNS zone. The email robot I've used in the past seems to have gone. Could someone please point me into the right direction how this is done nowadays? vy 73 de Marc, LX1DUC

Re: [44net] DDWRT Gateway Instructions
by lleachii＠aol.com 09 Sep '20

09 Sep '20

Mike, DD-WRT is not known to provide a method to compile/install the necessary software (i.e. a RIP44 routing daemon). Aside from this, I cannot recall if a tunnel can be established. Nonetheless, if you were to succeed standing up a tunnel, you'd need the routing daemon to properly configure your reply traffic. This routing daemon concern may be overcome by employing a Munge Script (hopefully DD-WRT has some tools like: `curl`, `ftp`, `grep`, `fgrep`, `sed`, `sort` and `diff` installed in the firmware). https://wiki.ampr.org/wiki/Munge_script You can start testing using commands from the startampr, OpenWrt, Ubuntu and/or Linux setup guides on the Wiki. Feel free to ask any questions (when you can stand up a tunnel). I've never used the Munge Script method, I'm sure others have (I should note that there's a script posted that can parse the encap.txt file - it's located on the Firewall page). The `ip tunnel` commands in `startampr` should be of help to test establishing the tunnel. https://wiki.ampr.org/wiki/Startampr#Script --- - Prior to using OpenWrt, I personally forwarded IPENCAP (IP Protocol No. 4) to a gateway running Ubuntu Server. - https://wiki.ampr.org/wiki/Firewalls#DD-WRT - Also see "Static IPENCAP Filtering of AMPR Nodes" here: https://wiki.ampr.org/wiki/Firewalls#iptables 73, - Lynwood KB3VWG

DDWRT Gateway Instructions
by Mike Swiatkowski 09 Sep '20

Does anyone know how to set up an AMPRnet gateway on a router with DDWRT? I don't want to use OPENWRT based on previous experience. Thanks, Mike, AA9VI

OpenWrt MSS Clamping - 19.07.4
by lleachii＠aol.com 09 Sep '20

09 Sep '20

All, First, welcome to the new Director and thanks for the work Chris! I wanted to inform those with OpenWrt-based nodes that version 19.07.4 should fix an MSS clamping bug that was reported to the developers. Some of you that setup OpenWrt routers have noted to me that MSS seemed problematic in one direction. I've worked around this with other OpenWrt operators by placing MSS clamping on the LAN as well as the tunnel-facing sides of the OpenWrt config. Hopefully 19.07.4 fixes the need for this. https://openwrt.org/releases/19.07/notes-19.07.4#major_bug_fixes 73, - Lynwood KB3VWG

ax25ipd setup with socat
by Marius Petrescu 02 Sep '20

02 Sep '20

Since I get questions about how to use the current kernels for axip or axudp tunnel setups, here is my solution for this, using socat: Here is an example for an axip tunnel. First, create a transparent pty pair, lets say axip an kip located in /var/ax25 (names and locations can be chosen freely): /usr/bin/socat pty,link=/var/ax25/axip,raw,echo=0 pty,link=/var/ax25/kip,raw,echo=0 & Next, attach the kernel side to one end and create a ax25 port let say 'aprs' with address 44.128.1.1 and netmask /32: /usr/bin/kissattach -l /var/ax25/kip aprs 44.128.1.1 ifconfig ax0 netmask 255.255.255.255 (ax0 is the first port created by kissattach) Also, configure port 'aprs' in the ax25 daemon and start it... /usr/sbin/ax25d The other end needs to be configured in the ax25ipd daemon config file to use the other end provided by socat: mode tnc (...) device /var/ax25/axip (...) route n0call 44.128.2.3. b (...) I think this will help, Marius, YO2LOJ
