Re: [44net] USENET news on AMPRNet

> USENET is obsolete. Don't waste your time on it. Well, not as obsolete as a mailing list... A closed news server would be much more convenient to use for discussions like this than a list... (and of course you could run it on a Raspberry Pi :-) Rob

USENET news on AMPRNet
by Brian Kantor 06 Sep '17

06 Sep '17

If you're one of the very few people who have ever taken advantage of the ability to read USENET news via AMPRNet and the news.ucsd.edu server, you should be aware that that server is failing from old age and will be taken out of service soon. We don't plan to replace it; Usenet itself is fading away. I co-authored the NNTP protocol some 31 years ago; that's a pretty good run for any internet standard. If you really need your Usenet fix every day, you might want to investigate www.eternal-september.org, which offers free Usenet access (but has very limited resources). - Brian

Brian, Can we make this list open to just those named in the description of the group… amprnet users and gateway operators for ops related items. -- Fredric Moses - W8FSM - WQOG498 fred(a)moses.bz

A /64 would be enough for a radio amateur with a simple network who wants to join a ham-radio network. It would surely not be optimal, but I would not expect an ISP that is that clueless (to allocate a single /64 to their customers) to be willing to route foreign network space to their customers. So what use would it be to have portable address space as a solution for that? Rob

I added a few IPv6 addresses for those who want to try. dig -t AAAA k7ve.ampr.org dig -t AAAA nw7dr.ampr.org dig -t AAAA a.nw7dr.ampr.org dig -t AAAA b.nw7dr.ampr.org dig -t AAAA c.nw7dr.ampr.org dig -t AAAA ar-dns.ampr.org -- ------------------------------ John D.

It's important to be aware of the timeline but this anniversary might also be a good time to look back at the history and think about the impact this assignment has made. What *new* technologies has been developed because of this network? Which crises have been mitigated using this network? Have it helped to spread the HAM radio "spirit" to the young people? What other good things have this network done? It's very sad for me to say that the only thing I can see about this network is a bunch of guys trying to stick with old technology (RIP? please.) at all cost and arguing who is more important in a tree of people allocating numbers. A /8 network is a great value nowadays, the IPv4 especially in Europe is in a huge crisis and getting new addresses is nearly impossible. From the other hand most of the address space in this network is unused but when you try to request allocation for yourself you can easily get rejected because of silly reasons. (I didn't even try to request one for myself after my friends showed me the coordinator responses.) There might be some things going on the used parts of the network but I couldn't find any example that could be genuinely useful to the world. Could you please prove me wrong or if I'm right try to consider sharing the address space with a "new" movement of hacking and hackerspaces? HAM radio should be all about hacking [1] but frankly speaking I don't see much of it in HAM radio space these days. There are some exceptions - i.e. "OFDM modem" thread from the last days but there are as rare as freakin' unicorns. This message is not meant to be mean. I'm just trying to pinpoint some things I've seen as an observer of this network and HAM radio (mostly in Poland but also the "worldwide" parts) and share some ideas how the things can be done better and provide a better value to the whole world.

IPv6 Firefox add-on
by Tom Kloos 04 Sep '17

04 Sep '17

Hi, Try "sixornot" for IPv6 status: https://addons.mozilla.org/en-US/firefox/addon/sixornot/ It works great for me with FF release 55 and 56 beta. Depending upon what version of Firefox you're using the web site may say "This add-on is not compatible with your version of Firefox.". This is due to Mozilla killing off all add-ons not implemented with WebExtensions starting with FF version 57. sixornot will still run fine up through FF version 56. Download it anyway! After FF 56 you'll have to switch to the PaleMoon browser (sixornot works great on it for me too). 73, -Tom WS7S At 12:16 PM 9/4/2017, you wrote: >Does anyone know of nifty little firefox add-on that will denote that >you are connected via IPv6 to the site?

John, I see IPv6 to http://nw7dr.ampr.org/ with netstat: TCP [2605:a000:1508:c178:78a8:fe60:2b78:1495]:65219 [2001:470:b:40f::3]:http ESTABLISHED TCP [2605:a000:1508:c178:78a8:fe60:2b78:1495]:65220 [2001:470:b:40f::3]:http ESTABLISHED TCP [2605:a000:1508:c178:78a8:fe60:2b78:1495]:65221 [2001:470:b:40f::3]:http ESTABLISHED Pinging k7ve.ampr.org [2001:470:b:40f::2] with 32 bytes of data: Destination host unreachable. Destination host unreachable. Pinging nw7dr.ampr.org [2001:470:b:40f::3] with 32 bytes of data: Reply from 2001:470:b:40f::3: time=99ms Reply from 2001:470:b:40f::3: time=102ms Reply from 2001:470:b:40f::3: time=117ms Does anyone know of nifty little firefox add-on that will denote that you are connected via IPv6 to the site? I'd like to be more aware of what all supports it in the course of my general browsing. I think that could really bring an awareness. Kind like the more recent "This site may not be secure" when Browsers detect login details over a non HTTPS connection. Having to sniff it with netstat to tell if its 4 or 6 is less than appealing.

Some time ago I noticed that my hack in PE1CHL-NET version 950819 (Aug 19, 1995): TCP SYN packets are examined when routed, and the MSS option will be adjusted down to the maximum MSS possible on the incoming and outgoing interfaces. Thus, a more optimal end-to-end MSS is chosen, and fragmentation is avoided (e.g. when running IP over NET/ROM somewhere inbetween the endpoints) pre-dates the addition of this feature in e.g. Cisco routers (ip tcp adjust-mss) by several years.... that would certainly have been patentable... > I'm reminded of this because Phil and I had dinner last night (he's > doing well, thanks) and got to chatting about the old days of packet > and AMPRNet.

Okay, its just something I have been wondering. I feel as commercial IPv4 addresses become more scarce, and more carrier grade NAT comes into play there will be more hams looking for solutions for the various internet ham radio services (IRLP, Echolink, D-Star etc), where they need the ability to control their port forwarding/firewall stuff. Basically I see a large number of folks seeking commercial VPN services. > >Interoperability of IPv4-only and IPv6-only hosts is a sticky wicket >that in my opinion NO ONE has solved satisfactorily. >- Brian I am slowing learning what a complicated mess it is (going to be) myself.
