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.

Can someone tell me if the encap.txt file is still available in the portal? I was looking for it today and cannot seem to find it. Thanks Jesse - WC3XS

I've also mentioned I don't have the time to write up proposals and do stuff to change it. As such I'm not going to bitch about it (or at least try not to). I'd be happy to start a working group if I have some help, but between my day job, building a simulcast repeater system, and doing the paperwork to get our repeater group to to be 501c3 non-profit I just don't have the time to do it all myself. I for one would like to get away from the IPIP encap, and get more distributed interconnects to the internet for 44/8. 73's -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

ampr.org IP addresses available for New Jersey.
by Mark Phillips 24 Mar '14

24 Mar '14

Hi all, It's a work in progress but the following link should provide a link to the IP 44/8 address allocation document for NJ. http://mrprosser.g7ltt.com We have very little AX.25 traffic in NJ but we do have a growing Mesh community which would benefit from this space. Hands up if you want some! Mark

Very nice! I think the best way to set up my local HamWAN is just to get off this list and go do it your way. Others can also make up their mind for themselves. Steve
