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)

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

Creating / hosting a new sub-mailing-list 44net-fr ?
by Toussaint OTTAVI 10 Sep '21

10 Sep '21

Hi, I often talked with French 44net guys, and it appears there's no current forum or mailing-list for communications between us, without polluting the world-wide 44net list. A long time ago, I planned to create a dedicated mailing-list 44net-fr on our mail server, but I never finished it, HI :-) The current project of a link between Corsica and France shows the need of such a tool, because private mails are becoming too bulky. My primary idea was to create a group on groups.io. As AMPR has now fundings and technical team, would it be possible to host such a 44net-fr mailing-list directly at ampr.org ? 73 de TK1BI

Addl Portal Services
by Kris Kirby 10 Sep '21

If we've got a TAC working new possible opportunities for 44net, I strongly recommend developing and deploying a Dynamic DNS (DDNS) service, and extending the portal so that end users may edit thier own DNS records. -- Kris Kirby, KE4AHR Disinformation Architect, Systems Mangler, & Network Mismanager

Known (US) providers to route/announce a 44
by Nick Hammler 05 Sep '21

05 Sep '21

(Sorry for repost. Chris kindly informed me that my messages are empty. I think it could be because GPG sig. Another attempt without it) Hi, I am aware there will be a slim chance for this to happen but having a 44net subnet directly routed would be super amazing. I am aware that "normal" providers likely won't do this except for business customers (at many $$$/months) and likely the subnet needs to be large (>=/24?) I could imagine though that small providers may be up for it (as an example, in a place I lived many years ago, I had a small provider; I contacted the CEO directly and he immideately agreed to assign+route me a /29 at no cost!). Are there any known providers (US, California) who could route a 44net subnet? To everyone who has their 44 routed directly: How does it work for you? Finally: The whole 44net is announed only by the UCSD gateway (as far as I understand). Wouldn't it be great to improve the connectivity, reliability, redundancy by having 44 announced by multiple people who route their subnet directly and then forwarding them to the mesh network via ipip? Is there a reason this is not done, other than nobody besides UCSD volunteered ? Thanks, KM6RDV
