As Brian said there is no central authority. The formula is based off your MAC address. >From memory it simply does HEX to decimal conversion for each of the last 3 octets. I found this: http://bloodhound.aredn.org/products/AREDN/wiki/TechRef/GUI/admin/PerlUI_IP… >The ham meshnet folks use net 10 internally; they assign the addresses >by a formula. They don't have a central IP authority. I don't recall >the exact formula and whether it's based on an encoding of the callsign >or the location of the station, but it was explained in a paper they published >in a past TAPR DCC, either 2013 or 2014. >- Brian

JNOS Gateway
by Garth Massay 28 Dec '15

28 Dec '15

Hi all, fairly new to the list but definitely interesting and enjoyable reading. On to the specific question, I have recently set up JNOS (PI) BBS, and have a specific AMPR IP for JNOS (44.22.0.11/32 ), is there a specific gateway address I should be using, or do I need to setup a AMPRNET gateway router? Fairly versed in Linux, although by no means an expert, if I do need to setup a router, can this be done on the same PI? Any assistance or guidance would be greatly appreciated,.. Thanks All,.. - Garth

With a Linux system instead of the Cisco you can automate that very easily. There are possibilities to automate it on the Cisco (see that link Steve gave you) but still it will be a lot easier to just use a Raspberry Pi or other small Linux system. Rob

To be a good gateway in the IPIP tunnel system you need to setup tunnels to all the other systems in the network. I think it currently does not even work anymore as the UCSD system now blocks such wrongly routed traffic. In a Linux system as a router, you need only one tunnel interface and the tunnel endpoints are defined in the route table (can be put in a separate route table when you want to use the same system both for internet and 44-net) That route table is automatically kept uptodate using a RIP daemon like ampr-ripd. Simple one-time setup and no more need to look after it and run regular scripts that fetch files and send commands. When someone changes their external address or subnets they route, your system will know about it after 5 minutes. But when you want to do it the difficult way, please go ahead! After all, learning and experimenting is what it is all about. Ready and working setups are not as interesting as finding out yourself how it all works and what are advantages and disadvantages of each method. Rob

Use use protocol 4. Beyond that I am not going to be able to help you, as I don't have any Cisco stuff. I snagged this from the list some time back that might be of help. And you might want to reach out to Jason KY9J. http://www.qsl.net/kb9mwr/wapr/tcpip/cisco.txt

Ham Class network
by Daniel Curry 26 Dec '15

26 Dec '15

Hello all, This is a little off the topic of 44 network, but I am curios. The 44 network is split into many regions for Amateur Radio to use. But does anyone know on how the10.x.x.x network is assign to Amateur Radio Ham Mesh network? Is there someone or a group that have the responsibility on dishing ip addresses? Sorry for the band width, but just curios.

FYI: DNS attack traffic
by Marius Petrescu 26 Dec '15

FYI: This is how a DNS attack reply profile looks like... (Seen via AMPR gateway, as someone uses YO addresses as the reply address) The reply amplification can be nicely seen for each attack sequence – targets are some hosts in China. http://www.yo2loj.ro/files/dns_attack_replies.png 73s de Marius, YO2LOJ

Anyway, I never do really basic config using a method this complicated. Risk is to high that it fails, e.g. when the portal is offline. I keep a file with important config items as a shell script and source it wherever it is required. Rob
