Hamnet over 70cm : NPR (New Packet Radio)
by f4hdk 08 Jun '19

08 Jun '19

Hello, I am Guillaume, callsign F4HDK, a french amateur-radio operator, and a hacker-maker. I would like to share with you my last project : NPR (New Packet Radio). All documentation is provided here : https://hackaday.io/project/164092-npr-new-packet-radio This solution can transport bi directional IP trafic over 70cm radio links, in a 'point to multipoint' topology, at datarate up to 500kbps. This can be used to increase the range of existing HSMM-Hamnet networks, at lower datarates. It's designed for "access", not backbone, and not designed for H24 use. Its is 100% open-source. Do not hesitate to ask me questions about it. I hope it will interest some people here. 73, Guillaume F4HDK

Block or error?
by Marius Petrescu 29 Apr '19

29 Apr '19

I have a question to the sysops running gateways in Europe. Lately, my subnets (44.182.21.0/24, 44.182.20.0/24 and 44.182.21.253 using gw 89.122.215.236 and yo2loj.go.ro) seem to have been lockout from different regions like Germany, Poland, Portugal and Bulgaria, while access from 44.182.21.1/32 still works. Is this intentional or just a configuration issue? Marius, YO2LOJ

VPN Broken link
by KJ7DMC 22 Apr '19

22 Apr '19

Subject: VPN Hello, Due to some annoying ISP firewalling that I cant control, I'm going to have to VPN into the network, or set up a vps somewhere and vpn into that. Ideally the first option since its cheaper :) The link to www.arrl.org/instructions under this article http://wiki.ampr.org/wiki/AMPRNet_VPN is invalid however. I'm not sure who exactly to contact about this, since I cant find an author's name in the wiki. Any help would be appreciated. Thanks! -Nate

Never > mind that it's 100% RFC-compliant, they say it's bad guy behaviour. I agree. Sending mail to google (and also hotmail/outlook) has become very unreliable. E.g. when using @amsat.org or other forwarding services like @veron.nl or @vrza.nl (Dutch amateur radio societies) it will usually not work. I do not really want to use my ISP mail address, so it looks like I have to register my own domain to get this fixed. For now, I have set an autoreply (from the ISP mail address) encouraging people to use a different address and look in their spambox when they expect a reply. I hear that it is customary in the circles of gmail/hotmail/outlook users to send a Whatsapp message "I have sent you an e-mail"... Rob

> Everyone happy with this? Any comments? It would be nice if the mail had some info about what a gateway is and why you (don't) want it, e.g. with a pointer to the wiki page. I have found that some people add a gateway entry because they think this is some form of registration of their existing (not IPIP mesh) router e.g. connected via radio or via one of the other VPN types we support. They think it would be useful to be registered in some list. That is how the problematic gateway came into existance, and there are several others like that registered in the Netherlands, that did not become problematic only because they had no subnets. When being listed is what they actually want, of course they should not register a gateway. But it is what they do, partly because there is a lack of higher-level explanation of concepts. And after receiving that mail message they probably still don't understand what they are doing wrong. Maybe a pointer to HamnetDB could be useful. Registering there is probably what they want. Rob

amprd setup issues
by Marius Petrescu 16 Apr '19

16 Apr '19

Hello, To all amprd users (this does not affect setups using the kernel tunnel driver and ampr-ripd). Due to changes in the 4.x kernels, there's a problem with the system replying with "icmp unreachable" to incoming IPIP traffic. This will possible drop incoming traffic, including the RIP broadcasts (resulting in incomplete route tables). Please switch to an ampr-ripd setup or filter outgoing icmp messages on your WAN interface, using a rule like the one below: *iptables -A OUTPUT -o ethX -p icmp --icmp-type destination-unreachable -m state --state RELATED -j DROP* I hope I can find a workaround on this issue. Marius, YO2LOJ

> I don't think folks would add a gateway if they haven't been approved for a block. Well, actually they do. The problem is that the visitors of the portal do not know at all what the whole concept of the IPIP tunnel mesh looks like, how it is relevant within AMPRnet, and that it is only one of the options for getting connected. As there is no walk-through explanation of concepts like a registered subnet, a gateway, the resulting IPIP tunnel mesh, etc, people just blindly click on menu items and fill out forms. Then they have a gateway but the still don't understand how that all works. So they close the site and continue to look elsewhere for information, and when they find it they never come back to delete what they created. That is why it is good to remove that crud, but also it would be good to have some more explanatory text and/or pointers to where that can be found. And some warnings that this is not a system to voluntarily register some information about one's station, but that it is actually used for something and that you can actually break things by entering information. (of course we should strive for a situation where one cannot break the network for other users, but still one could break the routing of one's own subnet) Rob
