44net and ARIN IRR
by KM6RDV 01 Nov '21

01 Nov '21

Hi, As I have heard, it is not allowed for ARDC to create route objects in ARIN's IRR and for that reason, RADb is used. I am just curious why this is the case? (It seems in general, creating IRR objects is possible via IRR-online [1]) Best, Nick [1] https://www.arin.net/resources/manage/irr/userguide/

Thank you AMPR and Chris
by KM6RDV 17 Oct '21

17 Oct '21

Hi list, I hope I am not spamming this list; I would like to express my sinciere gratitude to AMPR (everyone who made and makes 44/8 for hams possible) and especially to Chris who helped me a lot in the process for a BGP routable network. Thank you for gifting me an enormous time sink. It was always a dream of mine to connect directly to the "core" of the internet, play around with BGP and, in some ways, completely independent of an ISP. I had given up this dream long time ago until recently my friend told me about AMPR. It's a privilege that hams are given the opportunity to experiment with something that would otherwise be out of reach for hobbyists, similar as radio would be without ham. (while the same with IPv6 is 'somewhat' still accessible, /24 prefixes meanwhile go for 15k and since this is the smallest for anything interesting [BGP, AS], it's just out of reach for experimentation) There are so many exciting things to play with. Subnetting the /24, using /30 or /31 networks for example is something I knew in theory but never really applied in that intensity because with RFC1918, there is no need. BGP I knew in theory but setting up bird and seeing how a session is established, a prefix is announced and watching via looking glass how it propagates through the global interconnected network brings this to a whole new level. I am currently trying to implement a "real" multi homing setup. I have two cheap consumer grade internet links: DSL and 5G. The latter one is CGNAT. Normally there is no way to make anything useful out of this (other than having a manual backup connection). For the first line, I created an ipip tunnel, for the second one a wireguard (due to CGNAT) and connect a third network over them. This network is now accessible straight from the internet on two lines. Exactly as the internet was originally conceived, the packets can now flow on either connection! In next steps I would like to set up OSPF (or maybe iBGP?) and possibly adding more tunnels to create realistic routing networks. And further down, I'd like to see if I can find something interesting to implement anycast. Maybe some spectrum sensing via RTL2832 at two different locations accessible via the same address? Let me know if you have any good ideas. Nick, KM6RDV

Setting Up JNOS to Postfix Integration For DKIM/SPF Issues
by n2nov＠n2nov.ampr.org 11 Oct '21

11 Oct '21

This may be beyond the scope of some since I mentioned JNOS, but the basics should be the same. I have been running the n2nov.ampr.org JNOS system since the late 90s, but recently any emails that I send to GMAIL and some other services are being rejected. The same happens when any email is sent to me from those same commercial SMTP services. This is all boiling down to the modern SMTP security functions are not part of JNOS. It has been mentioned that I should use the Postfix on the CentOS server that it sits on as it is already servicing various accounts that I maintain for clients and amateur radio groups. If someone else is using this arrangement already, I would like to see how you are doing it and what the limitations are. I believe the Santa Clara group was going to implement something like this a few years ago. Thanks in advance. -- de N2NOV n2nov(a)n2nov.ampr.org n2nov(a)n2nov.#rich.ny.usa.noam

10Gb/s Gateway Upgrade
by Chris Smith 30 Sep '21

30 Sep '21

The upgrade to a 10Gb/s link to the gateway machine went ahead at 10:30pm last night (UK time), 2:30pm Pacific. I am pleased to report that the upgrade was successful, we also took the opportunity to reboot the machine: previously it has been difficult to reboot the gateway machine as it messed up the switch it was connected to (the switch was configured with mirrored ports for the CAIDA telescope and a reboot stopped it working). The gateway machine is now connected to a different switch and I can reboot it without it causing any detrimental effects.

Sustained DDOS attack
by Chris Smith 28 Sep '21

28 Sep '21

FYI The gateway machine at UCSD has been under a sustained DDOS attack now for over 24 hours, so if anyone is seeing heavy packet loss through the gateway, that’s why. The 1Gb/s interface is max’d out. You can view the interface stats here: http://mrtg.portal.ampr.org 73, Chris - G1FEF — ARDC IT Director Web: https://www.ardc.net

no route to 44.0.0.1 from Wave Broadband
by Rob Salsgiver 27 Sep '21

27 Sep '21

Greetings all, Looking for a reason why I can't ping 44.0.0.1 from my connection via Wave Broadband. If I VPN to my workplace (Comcast) I can ping it just fine. Wave subnet is 66.235.20.x. Traceroute below. I can get well out from my own network but it seems to die closer to the 44 side. Any ideas?

Re: [44net] Sustained DDOS attack (Matt - VK2FLY)
by lleachii＠aol.com 27 Sep '21

27 Sep '21

All, I see a slight increase in traffic inbound toward my /24 at my tunl0 interface (0.6 kbps to 1.1 kbps) - most still appearing to be blocked by my firewall. From netflow data, the majority of this traffic appears to be: TCP, GRE and pings. 73, - Lynwood KB3VWG

44Net ham gate near Muskegon MI
by Chris 23 Sep '21

23 Sep '21

Hi all, I'm looking to get back on the 44net after many many years. There used to be a hamgate in Muskegon MI run by WB8I, and is also listed on the AMPR.ORG site - however my several attempts to contact him have gone unanswered. I also haven't heard anything on the radio local.... Does anyone have any information on a hamgate in the Muskegon / Grand Rapids area in Michigan? Any info is appreciated! 73 Chris KC8BAT

IPIP link from Google Compute Engine
by Matthew Chambers 23 Sep '21

23 Sep '21

So I have a linBPQ node running on a Debian VM at Google and it's working on my assigned public IP there. I found that while they can do BGP announce of a 44 net subnet but it'd take a bit futzing around that I'm reserving for if I can't do an IPIP tunnel from there. My bpq32.conf has this for my IPGateway config IPGATEWAY # My Pub IP 35.209.142.98 # My Int IP 10.128.0.56 ADAPTER ens4 44ENCAP 10.128.0.56 IPAddr 44.46.15.1/24 IPPorts 1,2,3 NAT 44.46.15.5 10.128.0.56 **** and I have 2 firewall rules setup besides the ones I need for BPQ stuff (telnet and AXIP links) ACCEPT IP 169.228.34.84 all protocols ACCEPT IP 0.0.0.0/0 IPIP I'd think the 2nd one would cover everything I'd need but I decided to go ahead and make one to accept anything from the 44net Gateway at 169.228.34.84 just in case. Anyone else attempted anything like this? I know I could go setup something with vultr but I'm trying to keep all my VMs in once place if possible (and avoid a 2nd hosting bill) -- -- Matthew Chambers, NR0Q -- The content of this email is confidential and intended for the recipient specified in message only.

5 GHz link over 250 km of sea between Corsica and France / Italy ?
by Toussaint OTTAVI 20 Sep '21

20 Sep '21

Hi all, Some friends from south of France submitted the idea of a 5 GHz link between France and Corsica. The distance is 200-250 km, mostly over the sea. It's far longer than what I could see on HamNetDB, for example. But it's shorter than WiFi world records (some of them attempted more than 10 years ago between Italy and Sardinia). I never attempted links longer than 40km, so I don't have any experience. And we don't have any SHF expert locally... 1/ Do you think a permanent and stable 250 km link over the Mediterranean sea is doable ? Are some of you using such long links in 5 GHz ? If so, could you share your technical experience here ? 2/ Are there any people from Italy on this list ? Are there any volunteers between Genova and Roma to attempt a link with the East coast of Corsica ? If it works, would there be an interest in establishing a permanent link ? Thank you for your comments, 73 de TK1BI
