Scenario: DE HAMNET user accessing NL user's web service

by Janko Mivšek

Hello everyone, To be more concrete and to better understand issues behind the TAC proposal, I draw a scheme for fictional scenario where German user with non-public 44 IP wants to access via HAMNET a Dutch user's web service, running on his computer with public 44 IP: http://ftp.eranova.si/44net/scenario-de-nl-s57nk-jul21.png Both have 44 IPs in 44.128/16 range covered in TAC proposal. HAMNET is a closed network, non accessible from Internet while Dutch 44net is completely open to public access. Two extreme cases therefore. German user has set a simple static route: all traffic to 44.128/10 should go via HAMNET while all the rest via NAT to internet. NAT is needed because his local 44 IP is from a HAMNET's subnet which is not announced all over the Internet via BGP. Contrary to Dutch user, which local 44 IP is from BGP announced subnet and therefore everyone from Internet can access his web server. Also, he can access anything on the public Internet without any NAT needed. Furthermore, he is proudly represented on the Internet as radio amateur because of his 44 IP. Now to the scenario: German user finds his Dutch college website interesting and he'd like to access it. But his 44.128/10 static route will direct him over the HAMNET, not to public Internet. No access possible until HAMNET is connected directly to Dutch 44net. Now suppose we connect both those nets too. Dutch web server will now respond to German college's web request and response will be hopefully routed back to him. Hopefully the requests from public internet will also be served as before. Am I correct with this scenario? Are there any routing issues, are they already solved? Or how to solve them? If this scenario doable, are there some more issues? Best 73 Janko S57NK

Is 44.159.159.0/24 allocated?

by Soha Jin

Hi there, I found an organization called SSL Corporation (AS38281) start announcing 44.159.159.0/24 since 2021-07-29 14:08:00. I found it here: https://radar.qrator.net/search?query=44.159.159.0%2F24 It is strange with that a renumber plan which says 44.128/10 will be used for radio only was just came out several days ago. I tried to find it on portal, but there is not such a prefix. I also tried to look it up with whois, but it reports a database error: $ whois -h whois.ampr.org 44.159.159.0 # # ARDC WHOIS data and services are subject to the Terms of Use # available at: http://www.ampr.org # # If you see inaccuracies in the results, please report them at # https://portal.ampr.org/contact-us.php # Database error# # ARDC WHOIS data and services are subject to the Terms of Use # available at: http://www.ampr.org # # If you see inaccuracies in the results, please report them at # https://portal.ampr.org/contact-us.php # This prefix is announced with a route object: route: 44.159.159.0/24 origin: AS38281 descr: Assigned by AMPRNET for radio experiment usage. admin-c: Charles Wang tech-c: Charles Wang mnt-by: MAINT-AS38281 changed: charleswang(a)nekollc.com 20210729 #13:20:12Z source: RADB I am here to ask if this announcement authorized? 73, Soha Jin

Re: [44net] Future of AMPRNet Should NOT BE AMPRNet

by Antonios Chariton (daknob)

Hello Ian! Speaking as the TAC again, RPKI ROAs and route(6) objects are also something we worked on. It’s going to be proposed later, definitely after the summer, and will hopefully help many users and make Internet routing more secure for everyone!

Problems with gw.ampr.org

by G1FEF

Hello 44Net, Just to advise that there is likely to be heavy packet loss through the gateway server at UCSD currently. The 1G link has been fully saturated since just before midnight PST (see attached MRTG graph). I can’t even login to the server reliably enough to see what the traffic is but I guess some DDOS is ongoing. I will keep you informed as and when I have further information. 73, Chris - G1FEF

Introducing Dan Romanchik - KB6NU - our new Content Manager

by Rosy Wolfe

Hello 44net! Given that he just posted info for the next community meeting, this is an excellent opportunity to welcome a new employee - Dan Romanchik, KB6NU, who is our new Content Manager. He'll be helping us with all things related to writing - newsletters, web content, and even helping with grantee proposals. Here's a little bit about Dan: Dan, KB6NU, has been a radio geek ever since he turned on his grandparents' Philco console radio about age 10. He got his first license at age 16, then obtained a BSEE degree from the University of Detroit. After working as a test engineer for a dozen years or so, he decided to direct his engineering talents in another direction and became a technical editor for Test&Measurement World magazine, a post he held for six years. After leaving the magazine, Dan was self-employed as a website developer and freelance writer. He blogs about amateur radio at KB6NU.Com and self-publishes the "No Nonsense" line of amateur radio license study guides. He's also self published *21 Things to Do After You Get Your Amateur Radio License" and *The CWGeek's Guide to Having Fun with Morse Code." He feels his biggest accomplishement has been helping thousands of people get their first amateur radio license or upgrade to General and Extra, either by reading his study guides or by attending the classes he teaches. He's very excited to now be working with ARDC and hopes that his work here will help even more people have fun with amateur radio. Please join me in welcoming him! 73, Rosy -- Rosy Wolfe - KJ7RYV Executive Director Amateur Radio Digital Communications (ARDC) ampr.org
