Does anyone have a valid current email address for Hank Magnuski, KA6M (one of packet radio's pioneers)? The only address I have for him is decades old and doesn't work anymore. Thank you. - Brian

What does it look like being on a mountain top engulfed by fire?

by Brian Kantor

Background: HPWREN is the High Performance Wireless Research and Education Network, implemented using commercial wireless equipment and housed on several mountaintops around southern California USA. A recent news item from them has some impressive images that you folks may find interesting. You'll need a high-performance web browser/viewer and network connection to get the most from it. - Brian ----- Forwarded message Subject: What does it look like being on a mountain top engulfed by fire? A new HPWREN update: What does it look like being on a mountain top engulfed by fire? is available at http://hpwren.ucsd.edu/news/20170815/ The article, contributed by Paul Bourke, shows an immersive time-lapse animation of a four-camera 360 degree view in high resolution of the Whittier Fire near Santa Barbara in July 2017, projected onto the inside of a sphere, within which a viewer can pan, tilt and zoom.

Re: [44net] Belgium AMPRNet coordination

by Brian Kantor

Ok, I've updated his email address in the portal to that address from the on4sax(a)on4sax.be address that it used to be, which has apparently been taken over by a domain parking service which does not deliver mail. We'll see if this address gets through. Thank you, Jan. - Brian On Mon, Aug 14, 2017 at 08:20:11AM +0200, Jan Poppeliers wrote: > robbie.delise(a)gmail.com > > 73, Jan > ON7UX > > > -----Oorspronkelijk bericht----- > Van: 44Net [mailto:44net-bounces+jan.poppeliers=online.be@hamradio.ucsd.edu] > Namens Brian Kantor > Verzonden: maandag 14 augustus 2017 7:25 > Aan: 44net(a)hamradio.ucsd.edu > Onderwerp: [44net] Belgium AMPRNet coordination > > Unless someone can supply me with a working email address for the Belgium > AMPRNet coordinator, Robbie De Lise ON4SAX, there won't be any more > allocations in the existing Belgium subnet because there is nobody to handle > them.

Belgium AMPRNet coordination

by Brian Kantor

Unless someone can supply me with a working email address for the Belgium AMPRNet coordinator, Robbie De Lise ON4SAX, there won't be any more allocations in the existing Belgium subnet because there is nobody to handle them. I need a mailbox that is actually read and responded to, not just one that doesn't bounce mail sent to it. Or if it's the case that he's turned coordination over to someone else, I wish someone would let me know. - Brian

DNS entry add and clean up

by Normand L

Hi folks. After many-many years of absence . I back in the amprnet world. I did allready put back mtlgw.ampr.org running on a raspberry pi. I got a few very interesting projects on going. I will need to do somes modifications in the DNS entry. In the past I was using a mail robot to do it , but no idea on how , I will definitly need a refresh on how 's done today. Your help will be precious. 73 Normand Ve2vax / VA2nq

Portscanning

by Rob Janssen

I notice extensive portscanning/vulnerability searching from IP address 44.26.108.60 It has reverse katagiri.desu.ne.jp which also matches with its forward. (kind of strange, as it is no ampr.org name and .jp has 44.129.0.0/16) Does anyone have an idea what is going on here? Rob

Re: [44net] I gave a talk tonight.

by Steve L

Brian I wish everyone took your stance on the rules that you talk about at roughly 41:46. That is pretty much how I do things myself. I agree 100 % on the arm chair lawyer thing not being productive and all it does is discourage experimentation and potential new folks. > https://www.youtube.com/watch?v=8EdDtLRgH7k&feature=youtu.be&t=1108 Its a good video overview of a well setup network. I plan to show it at a club meeting. Steve, KB9MWR

I gave a talk tonight.

by Tom Cardinal

I gave a talk tonight at one of our local clubs to see if any other local amateurs are interested in AMPRnet. I tried to stay out of the weeds to just give a general overview and did not present any slides. I did use slides as note cards on my iPad to keep from straying that I have now placed on my AMPR web server (n2xu.ampr.org) for the folks in attendance that might be more interested. There were about 20 or so folks in attendance and I think there are 3 or 4 that are interested. I will be doing another talk at the club where I was once President here in Fort Walton Beach and then for the folks that are more interested I will present another more in the weeds presentation at some point in the future. I'm big on trying to get 44net here on RF (slow 1200 or broadband at 5.8 GHz) down here and need others that are local in order to do so. I might be leveraging expertise here as I try to grow interest... so please bear with me and any new folks I bring aboard. With all that said, is there anyone out there performing intermediate routing... what I mean is anyone running a tunneled gateway and performing routing for other subnets over RF. I may request a second but separate allocation to experiment in that realm... I'd like to learn how to do that. I think it's a natural expansion for times when network connectivity goes out for an area where we can act as an RF gateway between the RF and the tunneled AMPRNet. My eventual goal is I'd like to bring the HAMWAN to the Florida panhandle... I think these are all baby steps to get there. Input, advice ideas and criticism are all welcome. -- Tom Cardinal/N2XU/MSgt USAF (Ret)/BSCS/CASP, Security+ ce

Re: [44net] I gave a talk tonight.

The main problem if you ask me is this the over the air baudrate/bandwidth rules. These prevent anything at truly usable speeds on non-microwave bands. Has anyone heard anything on that plan to do away with the baud rate part that was proposed to the FCC in 2013?

Re: [44net] eth0 VM incoming IPIP, RIP [no chksum], like dhcp mangle issue ???

by Rob Janssen

> 1. There is no socket option called that in FreeBSD. Amprgw is not Linux. I am aware of that. Sometimes those socket options have the same name, sometimes not. When looking this up I got the impression that it was added to Linux copying from BSD, but it appears to be not the case. In the Apple variant of BSD the same option exists but it is named differently. > 2. We're not using the kernel socket mechanism to construct the UDP packets Ok... well, it is possible to calculate the checksum of course but it is a bit tricky as it is not only a checksum of the actual packet but also of a "pseudo header" that is temporarily added in front of it... But again, it should not be required. The 0000 checksum indicates "no checksum" and it is valid. I think Maiko has a different issue, maybe the problem with multicast sockets? (try -r option to force raw mode) Rob
