New to 44Net with some rookie questions
by Komkit Listisard 16 Mar '22

16 Mar '22

Hello, Just got started on AMPR 44Net. Currently I have a /28 block and using Raspberry Pi 4 as my IPIP gateway at home OTH. My set up is Verizon FiOS > Verizon Router (for all none Ham stuffs) > DMZ from Verizon router to 192.xx.xx.144 (my Raspberry Pi gateway). Raspberry eth0 is 44.xx.xx.1 as gateway and eth1 is 44.xx.xx.14 as tunl0 for my Ham stuffs. My eth1 is connected to a 16 ports Ethernet switch to supply the connections to all my Ham stuffs. So far everything is working well. I was able to request an IP in the range of 44.xx.xx.2 – 44.xx.xx.13 no problem. Later a friend will help me setting up a Mikrotik router, I just had to order one first. For right now Raspberry pi is what I will be using. I have some questions that I was not sure or could not really find the answer to specific questions. Can I move my gateway over to VPS somewhere? Or the VPS setup is for the larger block not for individual home use. If I could do this using VPS then I could rent one up, no problem. I would also need some sort of the instruction or guidance on how to set this up using VPS service instead of a Raspberry Pi at home QTH. The instruction I found is more like the set up for /24 BPG type of thing. I do not have a use for that many IP addresses. Another question is I have 2 blocks of addresses, obviously they were on a different subnet. Could I use one Raspberry Pi gateway, one gateway address? If that is possible, how do I add the 2nd block of IP range to my existing Raspberry Pi gateway setup or later on Mikrotik box? 73, Kit W3KIT/ HS0ZOE Sent from Yahoo Mail on Android

Continued commercial abuse of AMPRNet in Belgium
by Jeremy Cooper 24 Feb '22

24 Feb '22

Hello all, I’m sorry to escalate this back to the list, but I’d like to report that there is still significant commercial abuse of AMPRNet allocated subnets in violation of the AMPRNet Terms-of-Service and nothing appears to have been done about it, despite my repeated attempts to raise the issue with the abuse(a)ampr.org <mailto:abuse@ampr.org> mailbox. There are some 260 Helium Hotspot miners using the address space 44.144.124.0/23 to earn monetary rewards on the Helium cryptocurrency blockchain. While I am a fan of Helium and have managed to make it my full-time job, I am not a fan of seeing the AMPRNet address allocations be abused this way. Can we discuss this here, as a group? 73, Jeremy

Helium network
by Steve L 24 Feb '22

24 Feb '22

While the abuse concerns should be addressed off list, I think there may be benefit from some basic discussion about this network. I'd be willing to bet most are unaware of this network, that it mostly uses LoRA modulation to build a decentralized network for slower speed data applications. I feel there is a good amount of overlap to what we do in ham radio and there could be things learned from it. I'd be interested in knowing who is using the helium network (package delivery folks I'd assume, among others) and what light weight protocols and data they use. A few years back someone at a DCC meeting did suggest the concept of just such a network for the internet of things. And there have been a few papers on LoRA. I'm not interested in the crypto aspect of the network nor does that fit the discussion here. But if the hardware entry cost was lower or there was a way to build your own gateway I'd probably be doing that. Pity there isn't enough of density of interested hams locally to do what they are doing. So is there anyone else doing things with LoRa chipset enabled hardware with dialup speed applications in or out of ham radio.?

IPIP tunnel external IP changed
by Rob PE1CHL 09 Feb '22

09 Feb '22

Today our external IP for the IPIP tunnel towards 44.137.0.0/16 has changed from 213.222.29.194 to 145.220.78.2 It appears that some stations have configured this statically, so it has to be changed. (of course those that use the RIP transmissions from AMPRGW have no issue with this) Rob

Internet linked RDF networks
by Robert Simmons 27 Jan '22

27 Jan '22

To all. I've recently been duly scolded for soliciting $ for my DoppSite program, which is a big no-no here on 44NET. I'm actually not soliciting $... the program is 100% free... but the description on the website is very old... and it does mention getting a custom version for a sum of $. That description is WRONG... the program is FREE... if you click the download link, it won't ask you for any $... try it... =========== Sorry for the confusion... a lengthy explanation follows... but I guess I better provide it... At one time ( many years ago ) I had a DEMONSTRATION version of that program that was FREE, but it only generated DF bearing lines that were one mile long. I gave that away "for free", to promote the REGULAR ( commercial ) version, which I tried to sell ( I think ) for $ 99, and that one had DF bearing lines 25 miles long. That REGULAR version plotted at a "fixed" DF location that could NOT be changed... the customer had to specify that location, when ordering it. I did that to prevent s/w piracy... so the REGULAR program couldn't be copied and used at another DF site, just to dodge the $99 fee for the second site. Each REGULAR version was "hand carved" for a specific LAT / LONG, so it would be useless at another DF location. ============ No-one ever responded to that, so a few years later I just upgraded the DEMO version to display a 25 mile DF bearing line... and gave it away "for free"... but I never updated the website text that described it. By that time, I had given up hope that anyone would pay for it... in fact, it seemed no-one was even looking at it, so I had no reason to update the text information. ============ >From time to time, I would run into someone who MIGHT have an interest in that technology, so I would send them a link to the download, so they could try it. I figured they better look at the BEST version of that program... that's why I upgraded it to 25 miles... and that's what you will get NOW, if you download, install and run it.... for FREE. ============ I've also been chastised for not offering the source code, and embracing the "open source" model of software... I'm not averse to sharing the source code, but it's written in VisualBasic 6 which is an obsolete language, no longer supported by MicroSoft. Despite that, some people still write code with it, and it runs basically on any PC machine from Windows 95 to Windows 10. In the spirit of full disclosure, I've zipped the folder containing ALL the Doppsite_Demo ( VB6 ) source code files, and uploaded it to my website for others to get... You will find it HERE : www.silcom.com/~pelican2/DoppSite_Demo.zip 16 megs zipped, 25 megs unzipped. ============= I've got more to say, but this is plenty for one day... I'm not trying to make any $ on this, I'm retired and ( thank God ) I don't need the $... I'm not rich, but I have enough. Speaking for myself, I want to see someone create a DF network... even a simple one... just to prove this technology works... I won't explain why I've developed it, ( that's a whole other story ) but it's been a passion of mine for many years... I've done as much as I can do "alone"... I hope to meet people here ( on this forum ) who aspire to make DF networks, but who lack the technology to do it... or even a plan for it. ============= I've already got almost all the technology for it, and I'll share it... for folks that are serious about it... I'm 70 YO and it's not doing me any good sitting here... This DoppSite program is the first ingredient in such a network... and the people on this forum are pretty sharp, I hope they can see the potential it offers... They offer grants here also. I don't want or need one, but someone making a network might... I can offer a lot, but I can't offer everything. Enough for one day... thanks again folks. Bob S.

Re: [44net] Security Idea/test: firewall rule for non AMPRGW routes
by lleachii＠aol.com 27 Jan '22

27 Jan '22

Marius, This would only apply: * if there were a malicious node on AMPR sending as 44.0.0.1 * someone "accidentally" configured RIP to broadcast routes on their AMPR interface (though there likely won't be AMPR-routes here and not 44.0.0.1; but this could wipe our tables with a misconfigured SNAT rule lying around) And yes indeed, I currently use the 2 rules - similar to what you mentioned, and you know I'm ever grateful you made sure ampr-ripd works with it! It will also ensure that a u32 rule works as ampr-ripd does not "pull the route packets off the wire". ;-) I had to upgrade my QTH router/AMPR gateway to OpenWrt 20.04.1 running on an x86_64 (I just cross-compiled with the SDK to the musl-based C running on it), so I have some more CPUs to work with for more firewall, logging, IDS/IPS, etc. now. 73, - Lynwood KB3VWG ---- Excuse the OpenWrt Syntax: config rule option src 'wan' option name 'Allow-AMPR_IPENCAP' option family 'ipv4' option proto '4' option ipset ' ipipfilter' option target 'ACCEPT' config rule option target 'ACCEPT' option proto 'udp' option dest_port '520' option name 'Allow-AMPR_RIP' option family 'ipv4' option src 'amprwan' option src_ip '44.0.0.1' option src_port '520' option dest_ip '224.0.0.9'
