Marius, Correct you are. Dumb mistake on my part. Happens when you have been up all night apparently.

195.146.144.9.80 oddness

Weirdness: I don't have a DNS entry for 44.92.21.1.80, as it is non existant on the network I feed. So how is it that I get constant activity from it? Does anyone else get a lot of traffic from that IP address? tcpdump -vvv -s0 -n proto ipencap 9515068, win 8192, options [mss 1460,nop,wscale 8,nop,nop,sackOK], length 0 195.146.144.9.80 > 44.92.21.1.80: Flags [S], cksum 0x0a01 (correct), seq 186 tcpdump -i eth0 -vvv host amprgw.sysnet.ucsd.edu or ip proto \\icmp amprgw.sysnet.ucsd.edu > CPE-75-87-213-229.new.res.rr.com: IP (tos 0x0, ttl 81, id 33817, offset 0, flags [DF], proto TCP (6), length 52) sme.sk.http > hsmm-gw.kb9mwr.ampr.org.http: Flags [S], cksum 0xdff7 (correct), seq 1415087399, win 8192, options [mss 1460,nop,wscale 8,nop,nop,sackOK], length 0

Wiki User Registration Impossible?
by Ryan Elliott Turner 29 Mar '14

29 Mar '14

Hey list, I'd love to document some of the recent discussion (private 44net space? rip vs encap? encap location?) but I can't edit any pages without being authenticated it seems. On top of that, there is no link to the registration URL. When I try to go to the registration URL ( http://wiki.ampr.org/index.php?title=Special:UserLogin&type=signup ), I get the error "You do not have permission to create this user account". So, I'd love to help start documenting this stuff, but seems like I'll need some help myself first. -- Ryan Turner

44Net Private addressing
by Rod Ekholm 29 Mar '14

29 Mar '14

I found a statement on http://en.wikipedia.org/wiki/AMPRNet that says: 44.128.0.0/16[edit<http://en.wikipedia.org/w/index.php?title=AMPRNet&action=edit&section=2> ] *44.128.x.x* is the testing subnet and consists of 65,536 (216) addresses. Much akin to 10.0.0.0/8, 172.16.0.0/12, 169.254.0.0/16 or 192.168.0.0/16, this is an unroutable private IP block<http://en.wikipedia.org/wiki/Private_network>. Connectivity to the rest of the network should be given through router gateways <http://en.wikipedia.org/wiki/Gateway_(telecommunications)> much as one would do with Network address translation<http://en.wikipedia.org/wiki/Network_address_translation> in any other private IP block. Is this truly the case? When I look at the portal, this /16 would be towards the end of the US allocations, and just before the Japan allocations. If this is not true, do we have a Private block in the 44/8 for use that is not routable? -- Rod Ekholm kc7aad(a)gmail.com

Interesting reading! I too would like to see a routed approach - all this clumsy tunnelling house of cards junk is never going to be reliable. The overly-managed approach doesn't help either. It needs to be far simpler to manage a /24 than what we have now. All the legal speak in that "contract" can get binned too. As far as outdoor links are concerned - why do you not use the Ubiquiti 2.4,3.3, and 5.8Ghz gear? It goes really really over long distances even without external amps, and will happily run in the ham bands.

I have a quite simple setup for a Raspberry Pi as a Linux AMPRnet gateway, but in my experience everyone's setup is different and what works fine for me is not what other people want to use. My Raspberry Pi is in a datacenter so no NAT worries. It terminates all tunnels (IPIP) and users Marius' RIP daemon for automatic routing. This works very well after we have ironed out some problems. It also runs a local copy of KA9Q NET which I access from home via "screen", and it forwards a subnet of 44 adresses via an IPsec tunnel to my home machine, where several of these addresses are used to provide other services (e.g. WWW). The setup basically only brings up tunl0 and assigns an address, sets up a separate route table and rules for net-44, manually inserts a couple of routes and then fires up the ampr-ripd. Maybe 10 lines of bash code, that is all. As I wrote, the setup is very simple and the details vary enough for it to be less useful to others than I thought. I forwarded my complete config to a fellow amateur who has a Raspberry Pi as well, ready for him to load it, but he never did that and somehow prefers to build it again for himself. And probably that is better anyway, as most of the fun of building such a thing is the studying of the matter and the debugging. Tinkering with the Raspberry Pi and networking is like homebrewing, copying an existing configuration is like buying a shiny new Icom. Rob

--- Snip --- One of the major drawbacks to the IPIP tunnels used to transport AMPRNet data is that they don't work when you are using Network Address Translation (NAT). --- Snip --- I disagree. As long as protocol 4 is forwarded (or just use DMZ) it works fine. I use 192.168.1.X on all my normal stuff at home, and my Ras Pi running rip44d has a an address of 192.168.1.2. In my main home router I point DMZ to that address of the Pi. I use a single USB dongle and that interface has a 44.92.X.X address and connects to some Ubiquiti gear. Works fine. http://www.qsl.net/kb9mwr/wapr/tcpip/rip44d.html http://www.qsl.net/kb9mwr/wapr/tcpip/

Ok what are people actually DOING over their Internet-connected 44 radio net? VOIP? APRS? Video links? Repeater linking? IP cameras? Remote bases? Any innovative suggestions? Steve -- Meshnetworks - Rangitaiki Plains Rural Broadband Internet Providers +64 21 040 5067

Can't add redundant AMPR gateway to portal
by Bart Kus 25 Mar '14

25 Mar '14

Screenshot This network (44.24.240.0/20) is available via both 209.189.196.68 and 198.178.136.80. However, I'm unable to list more than one point of contact. I realize this was probably a design decision at some point, but it doesn't seem like a good idea from a redundancy perspective. --Bart PS: If you're wondering why the image looks like crap, it's to satisfy the puny 32kB message size limit of the list.
