Routing of 44.0.0.0/8 how are routes announced to users?
by Benoit Panizzon 26 Feb '18

Dear List I'm pretty newly connected to hamnet, and also work at an ISP. I always assumed 44.0.0.0/8 would not be announced to the internet, but only routed privately on hamnet. Now I see routing issues I don't quite understand as for me this looks like routing is completely broken... On the internet core router I see that 44.0.0.0/8 is being announced by AS7377 (UCSD). But IP Addresses from the swiss HamNet range are not reachable via AS7377. So what is the point announcing the whole range to the internet? There is no 'more specific' route to 44.142.200.1 On the other hand I cannot reach parts of hamnet via hamnet. Take for example the Primary DNS of ampr.org: ampr.org. 3600 IN SOA ampr.org. ampr.org has address 44.0.0.1 1 gateway (157.161.57.65) 2.947 ms 2.887 ms 2.847 ms 2 mikrotik-hamnet.woody.ch (192.168.57.243) 4.937 ms 4.920 ms 4.887 ms 3 rf0.am-32.hb9am.ch.ampr.org (44.142.162.97) 21.810 ms 24.858 ms 29.860 ms 4 bb-hb9am-30.db0wbd.ch.ampr.org (44.224.90.81) 29.847 ms 32.792 ms 32.771 ms 5 wan-db0wbd.hc.r1.ampr.org (44.148.240.45) 78.907 ms 81.925 ms 84.438 ms 6 dc1-dc2.hc.r1.ampr.org (44.148.255.253) 97.808 ms 98.107 ms 113.973 ms 7 wan-db0gw.db0fhn.ch.ampr.org (44.224.122.2) 113.986 ms 113.149 ms 118.384 ms 8 db0fhn.ch.ampr.org (44.130.60.100) 126.890 ms 118.628 ms 137.776 ms 9 * * * My Gateway has a default route to the internet and a static route for 44.0.0.0/8 pointing to my WLAN Link to a 'public' Hamnet AP. So what is the point of having sort of a split-brain situation on the 44.0.0.0/8 hamnet ip range? I 'see' ospf packets on the WLAN link, but they only seem announce the local routes withing the swiss part of hamnet, not the global routes. Sort of makes sense, as you probably would run bgp to interconnect the different hamnet as numbers. So do I need to get an own hamnet as number? As a User?!? Or what mechanism is there supposed to be to tell a user which hamnet ip ranges are reachable via internet and which ones are reachable via hamnet. 73 -Benoit- / HB9EUE

Anyone running an open AMPR VPN willing to share?
by David Ranch 17 Feb '18

Hello Everyone, I'm helping out a local HAM getting an IPIP AMPR setup working but his current AT&T Uverse / Pace s 5862ac unit doesn't seem to be playing nicely. Yeah.. I know.. Shocking! Anyway, touter/NAT mode seems to *only* want to forward TCP/UDP protocols (typical) and it's DMZPlus feature mode seems to be breaking his Wifi network. As we maybe hack with the DMZplus feature tomorrow, I was curious if there is anyone willing to offer up a VPN connection to his Raspberry Pi as a Plab-B: Looking through the archives, there was http://wiki.ampr.org/index.php/AMPRNet_VPN but that link is 404. I know there is also the http://wiki.ampr.org/wiki/AMPRNet_VPN link but I know other HAMs are/were offering less complicated setups. I can help him setup any offering be it IPSEC, SSL-VPN, etc. He's not looking for any sort of performance.. just general IPIP access to play around, etc. at the moment. If already hosting or you're willing to host a solution, let me know. Thanks! --David KI6ZHD

setting up a Linux gateway with a dynamic public IP
by Kevin Fox 13 Feb '18

All the examples I have found have a static public ip, is there a way to do it with a dynamic public ip, my ISP does not assign statics to residential customers. cantantes laudat orbis terrarum

I have followed the directions in http://lz4ny.eu/en/amprnet-44-rip/ to setup my GW, but all I get when I run ampr-ripd is the following root@thor:/home/w0kcf# ampr-ripd -d -i tunl0 Using gateway 192.168.1.1 for direct 44net endpoints via interface enp0s18. Waiting for RIPv2 broadcasts... Network configuration is as follows w0kcf@thor:~$ ifconfig enp0s10 Link encap:Ethernet HWaddr 00:14:6c:81:ff:fe inet addr:44.26.1.80 Bcast:44.26.1.95 Mask:255.255.255.240 inet6 addr: fe80::214:6cff:fe81:fffe/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16335 errors:0 dropped:10870 overruns:0 frame:0 TX packets:58 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1273233 (1.2 MB) TX bytes:6874 (6.8 KB) enp0s18 Link encap:Ethernet HWaddr 00:13:8f:7a:c8:aa inet addr:192.168.1.9 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::213:8fff:fe7a:c8aa/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:23028 errors:0 dropped:0 overruns:0 frame:0 TX packets:17964 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:6155448 (6.1 MB) TX bytes:2789754 (2.7 MB) What am I missing? 73 Kevin W0KCF
