EC2 Router Reference Implementation
by Stephen Thomas 24 Jan '20

24 Jan '20

To learn the routing protocol, I created an Amazon EC2 instance of a Linux Ubuntu router inside a virtual private cloud (VPC) where I have full control over IP and can open 0.0.0.0/0 in both directions over all protocols (EC2 without a VPC only permits TCP/UDP/ICMP access control). When I run the daemon in verbose mode it is stuck calling home: ubuntu@ip-192-168-44-12:~$ sudo ampr-ripd -d -v -L KZ0FOX@EM89mx Using metric 0 for routes. Using TCP window 840 for routes. Using gateway 192.168.44.1 for direct 44net endpoints via interface eth0. Calling home Waiting for RIPv2 broadcasts... Calling home Calling home Calling home This system is online in the portal as 3.135.62.22 ( ec2-3-135-62-22.us-east-2.compute.amazonaws.com) and subnet 44.76.0.12/32. Setting up a reference implementation like this one may be good for learning the basic premise and ability to test out a configuration with less variables than one may have at home with an ISP. I welcome any constructive comments or suggestions. Best regards, Stephen Thomas

Very sad news. I was talking to him just the other day. What a shock. My condolences to his family and those close to him. As busy as I imagine he must have been, he always had time to help.

Linux GRE Tunnels
by Jason McCormick 08 Dec '19

08 Dec '19

I'm running into an interesting problem I thought maybe someone in this community would have run into before. We're working on a project to redesign and re-IP our entire radio network. Part of the goal is to stop using OpenVPN and IPSec tunnels (long story) and move exclusively to GRE-based tunnels. The plan is to have two Linux VPS hosts running at a provider with our 44Net allocation and an IPv6 allocation advertised and then routed into the radio network over GRE tunnels to 3 different locations that are all backhauled together. One of the primary goals is to do dual-stack throughout the network. I have one site setup working perfectly - "gre0". It's passing IPv4 and IPv6 traffic over the GRE tunnel. One *key* point to this is that the GRE connection endpoints are iPv6. IPv4 isn't doable for this connection (again, long story but not an option). When setting up the second GRE tunnel "gre2", nothing would work even though the configuration was the same EXCEPT for the fact that the second GRE tunnel was using IPv4 addresses for the GRE tunnel endpoints. Linux keeps spitting out a very odd error when I try to ping across the tunnel I cannot find reasonably documented anywhere: ip6_tunnel: gre2 xmit: Local address not yet configured! The key was the "ip6_tunnel" part that took me awhile to figure out. After experimenting, I've found that if I have one GRE tunnel using IPv6 endpoints (ip -6 tunnel add gre0 mod ip6gre) and one using IPv4 endpoints (ip tunnel add gre2 mode gre), only the gre0 tunnel will work and the gre2 tunnel seems to believe it's missing an IPv6 address. If I delete the gre0 tunnel, the gre2 tunnel immediately beings working with both IPv4 and IPv6 traversing the GRE. I cannot find any documentation that describes this behavior or why it would be the case. I can't switch to IPIP tunnels because I haven't found a way to do a dual-stack tunnel between the endpoints - seems like you can only do one IPIP tunnel between two endpoint IPs regardless of type (ipip, ipip6, ip6ip6, sit) Anyone have any deep wisdom on GRE tunnels?

Brian Kantor, WB6CYT, SK
by Phil Karn 23 Nov '19

23 Nov '19

I have very sad news. My good friend, Brian Kantor, WB6CYT <https://photos.smugmug.com/photos/i-qRxpLrc/1/X4/i-qRxpLrc-X4.jpg>, suddenly passed away this week at his home in San Diego, California. Brian retired only two years ago after 47 years of service on the staff at the University of California San Diego (UCSD). Way back in the mid 1980s, Brian and I founded AMPRnet, the TCP/IP over amateur radio network. He continued to manage it until his passing. Brian recently created and served as chair and CEO of Amateur Radio Digital Communications (ARDC), a charitable foundation funded by the sale of unused AMPRnet IPv4 addresses. ARDC promotes STEM education and amateur radio digital development through scholarships and by funding the development of open source hardware and software. Brian will be sorely missed and impossible to replace. Memorial arrangements will be announced when known. Phil Karn, KA9Q

It is with great sorrow that we learn of Brian's passing. For dozens of years he has worked in support of Amateur Radio and gone far beyond what could be expected of an individual to make Amateur Radio digital operations a success. In the early years he almost single-handedly insured that the interface with the educational and commercial worlds were properly managed. As Phil stated, it will be impossible for us to replace the talent and knowledge he has provided. This event presents another opportunity for us to learn how to work together for success in the future. It is critical that those of us still around, including those of us from the Southern California Digital Coordination Council days, endeavor to pass on all that has been learned. There are less and less of those Don listed still with us. I for one think that ARDC can play an important role in ensuring our continued success.

IPIP and RIP configuration on a Mikrotik
by Paul Greeff 16 Nov '19

16 Nov '19

Hi OM I'm hoping to pick someone's brain with regards to the IPIP and RIP config for AMPRnet on my Mikrotik at home. I'm using the guide http://www.yo2loj.ro/hamprojects/ampr-gw-README.txt, which indicates after step seven and a few minutes of waiting I should see my routing table populated with routes with a 44rip routing mark. Nope. I've monitored for port 520 on the IPIP as well as Internet facing interface and see no activity. I also haven't seen a single packet on the ucsd-gw interface (not sure if I should at this time). So I'm obviously missing something important and perhaps fundamental in this configuration. Please send some of your wisdom my way. Regards Paul (ZS6IO) -- Paul Greeff email(a)paulgreeff.com Office: +27 86 100 3117 Cell: +27 83 954 3453 Fax: 086 659 0511 Winlink: zs6io(a)winlink.org

IPIP and RIP configuration on a Mikrotik
by Thomas Glaab 15 Nov '19

15 Nov '19

That guide worked for establishing the tunnel, but I don't seem to get working RIP packets. The IP address for my local port is 44.x.y.1/32 with a network of 44.x.y.0 (/24). But the IP address on the tunnel interface is 44.x.y.2/32 with a network of 44.0.0.0 (/8). Somehow this works and the tunnel connects. Every five minutes I see some packets come in and a packet capture shows the clear text password in them. But the RIP listener isn't seeing them. I even set the RIP to listen for any advertisement (not just 44.0.0.0) on any interface. tg. AJ4UQ.
