Cathryn, I see your ping requests arriving at 169.228.34.84 no problem, and they are being encapsulated at sent to 50.79.209.150, again, no problem. Nothing is coming back from 50.79.209.150. This suggests that something is filtering out protocol 4 (IPIP) between 169.228.34.84 and 50.79.209.150. A traceroute from 169.228.34.84 to 50.79.209.150 using ordinary UDP works, completing after 18 hops. The last few hops in that path look like this: 14 162.151.87.226 12.097 ms 12.315 ms 12.088 ms 15 162.151.79.134 12.735 ms 12.744 ms 12.773 ms 16 68.87.227.122 13.080 ms 12.983 ms 12.920 ms 17 * * * 18 50.79.209.150 37.676 ms 42.664 ms 33.084 ms A traceroute from 169.228.34.84 to 50.79.209.150 using protocol 4 (IPIP) does not complete, and there are no responses beyond hop 15. The last few hops are: 12 68.86.84.150 11.117 ms 12.601 ms 12.734 ms 13 68.86.94.154 11.761 ms 11.743 ms 11.340 ms 14 162.151.87.226 12.469 ms 12.162 ms 12.392 ms 15 162.151.79.134 12.757 ms 12.800 ms 12.797 ms 16 * * * 17 * * * 18 * * * This suggests that hop 16, 68.87.227.122, is not accepting/passing protocol 4 packets. The hostname for that host is lag-2-240-acr07.pinole.ca.sfba.comcast.net. I hate to throw you to the wolves of comcast's customer service line, but you may need to find out from them if they suddenly started filtering out inbound IPIP packets at that router. - Brian On Sat, Jun 29, 2019 at 09:50:40AM -0700, Cathryn Mataga via 44Net wrote: > Date: Sat, 29 Jun 2019 09:50:40 -0700 > From: Cathryn Mataga <cathryn(a)junglevision.com> > To: AMPRNet working group <44net(a)mailman.ampr.org> > Subject: Connecting to 44net > > I'm not connected to 44net anymore, when I ping, to me at least, my > outgoing packets look correct, but I get no response ever. > > I'm trying to put together as much as I can.

44Net OpenNet VPN Setup
by matthew＠alberti.us 03 Sep '19

03 Sep '19

Hi everyone, new 44Net list member here. I'm trying to setup the OpenVPN connection to the OH7LZB VPN server. I'm primarily using this link (http://wiki.ampr.org/wiki/AMPRNet_VPN), but I am planning to update it once I get my connection working. Looking thru the archives, it seems a number of us have had challenges with the setup. If someone has successfully configured it recently, maybe you can help me out with my setup? The encryption and auth seems to not negotiate, the connection never sets up. Per Hessu's response to my email (below), perhaps it has to do with the newer version / algorithms trying to get along with the server version. Thanks in advance for any assist. - Matt / KM4EXS -------- Forwarded message ------- From: "Heikki Hannikainen" <hessu(a)hes.iki.fi (mailto:hessu@hes.iki.fi)> To: matthew(a)alberti.us (mailto:matthew@alberti.us) Sent: August 18, 2019 12:13 PM Subject: Re: 44Net VPN Setup Hi, I generally prefer to have these discussions on a mailing list so that the answers are archived publicly, and others can look for existing answers from the archive instead of asking the same question again. I run aprs.fi so I get a lot of questions and emails. The log, at this verbosity level, doesn't actually say what went wrong in the negotiation. I think there was a thread on the 44list before where someone resolved this issue, something to do with new versions of openvpn openssl refusing to use the older algorithms currently configured on the VPN server. https://mailman.ampr.org/mailman/private/44net (https://mailman.ampr.org/mailman/private/44net) On Sat, 17 Aug 2019, matthew(a)alberti.us (mailto:matthew@alberti.us) wrote: Hi Hessu, I pulled your e-mail address off the 44net mailman list.

Routing Help Please
by Albert Lawson 29 Aug '19

29 Aug '19

Greatings...!!! I'm setting up an AMPR Gateway on an Ubuntu 16.04 box. This box is behind a Ubiquiti Unifi USG. I'm forwarding IP Protocol 4 to the internal IP of the box. The layout of the box is two NIC cards...one that sits on my home network, the other card will handle my 44 net allocations with connection to the rest of the AMPR Net via the AMPR Net tunnel. When I first bring the box up, and before I bring up the tunnel, I'm able to ping the 44 net hosts inside of my network. Using TCPDUMP I can follow the flow of packets pretty easily. The problem starts when I bring up the tunnel. As soon the tunnel comes up, when I try to ping one of my 44 hosts, I can see the packets are now going out on the tunnel interface and not on the NIC card on my 44 network. I've gone through this line by line on my scripts, and the problem starts when the actual default route to the AMPR Gateway is added. From that point on, all the packets are sent thru the tunnel. I've tried three different versions of scripts that I've found on the Internet and the result is the same. Here's one script that I got off the AMPR Wiki: #!/bin/sh ### ## Create AMPRNet Tunnel and routing ## ## Configure Tunnel (put your ISP you received from your ISP Here). ip tunnel add ampr0 mode ipip local 192.168.12.158 ttl 255 ## Bring it up ip link set dev ampr0 up ## Enable Multicast in order to receive routes ifconfig ampr0 multicast ## Configure Policy Based routing # Packets to 44/8 network use routing table 44 ip rule add to 44.0.0.0/8 table 44 priority 44 # Packets from our 44 subnet use table 44 (put your AMPRNet Subnet here) ip rule add from 44.26.2.32/27 table 44 priority 45 ## Configure static routes # Default route for table 44 is to send traffic to amprnet gateway at UCSD ip route add default dev ampr0 via 169.228.34.84 onlink table 44 # Route packets for our net to local interface (put your AMPRNet Subnet here) ip route add 44.26.2.32/27 dev ens192 table 44 ## Start ampr-ripd to learn rest of mesh routes # Be sure to substitute the password you found earlier for <SecretPassword> # Put your static IP you received from your ISP here. ampr-ripd -s -i ampr0 -a 192.168.12.158 -t 44 I've tried the obvious stuff...removing the route, re-adding the route....but I can't seem to figure this out. Any input, ideas, suggestions would be appreciated. 73's Albert WB7AWL

DARPA Spectrum Collaboration Challenge (SC2) - OCTOBER 23, 2019
by Lori Guidos 26 Aug '19

26 Aug '19

I thought some of you might be interested in this upcoming event. It sounds relevant to our membership... Maybe a way to encourage other people to get their licences? Too far from San Francisco for me to participate... but I will be tracking the event from afar... As to the ongoing maiing list discussion: I would like to propose we form a subcommittee of interested members to review the organizational bylaws and make recommendations to the Board of Directors for improvements. I also think we need to communicate better and more efficently.. Perhaps we can add some newer open source software tools to ensure smoother communication? Lori Guidos KE6INO OCTOBER 23, 2019 Mobile World Congress Americas Los Angeles Convention Center : https://www.spectrumcollaborationchallenge.com/ - The Challenge - The DARPA Spectrum Collaboration Challenge (SC2) aims to ensure that the exponentially growing number of military and civilian wireless devices will have full access to the increasingly crowded electromagnetic spectrum. In this first-of-its-kind collaborative machine-learning competition, competitors will reimagine new spectrum access strategies in which radio networks autonomously collaborate to dynamically determine how the radio frequency (RF) spectrum should be used moment to moment, avoiding interference and jointly exploiting opportunities. SC2 teams will develop these breakthrough capabilities by taking advantage of recent advances in artificial intelligence (AI) and machine learning, and the expanding capacities of software-defined radios. The team whose radio design most reliably achieves successful communication in the presence of other competing radios could win as much as $3,500,000.

Improved Communications (Thread split)
by Bill Horne 25 Aug '19

25 Aug '19

I'm starting a new thread regarding this topic. On 8/24/2019 2:10 AM, Lori Guidos wrote: > I also think we need to communicate better and more efficently..

I am reluctant to endorse adoption of new methods or tools: they tend to become the problem they are supposed to prevent, drawing resources and time away from more pressing issues. This mailing list is stable, well-known, and easy to use. A new paradigm would require that each subscriber climb what might be a steep learning-curve, and once they do that, some will feel compelled to demonstrate their command of the new methods and/or software by adding to the amount of smoke surrounding our electronic campfire, without also adding enough light to make the changes worthwhile. Could communication be improved? Of course. Will having a new way to communicate automagically cause that to happen? I don't feel that it will. YMMV. HTH. 73, W4EWH Bill Horne

Another approach Re: Fraud

One approach that may generate some visibility of the issue - and possibly some action, or an investigation - would be to file a complaint with ARIN, the responsible entity fir all North American IP address allocations.
