Re: [44net] Connecting to 44net

Cathryn, I see your ping requests arriving at 169.228.34.84 no problem, and they are being encapsulated at sent to 50.79.209.150, again, no problem. Nothing is coming back from 50.79.209.150. This suggests that something is filtering out protocol 4 (IPIP) between 169.228.34.84 and 50.79.209.150. A traceroute from 169.228.34.84 to 50.79.209.150 using ordinary UDP works, completing after 18 hops. The last few hops in that path look like this: 14 162.151.87.226 12.097 ms 12.315 ms 12.088 ms 15 162.151.79.134 12.735 ms 12.744 ms 12.773 ms 16 68.87.227.122 13.080 ms 12.983 ms 12.920 ms 17 * * * 18 50.79.209.150 37.676 ms 42.664 ms 33.084 ms A traceroute from 169.228.34.84 to 50.79.209.150 using protocol 4 (IPIP) does not complete, and there are no responses beyond hop 15. The last few hops are: 12 68.86.84.150 11.117 ms 12.601 ms 12.734 ms 13 68.86.94.154 11.761 ms 11.743 ms 11.340 ms 14 162.151.87.226 12.469 ms 12.162 ms 12.392 ms 15 162.151.79.134 12.757 ms 12.800 ms 12.797 ms 16 * * * 17 * * * 18 * * * This suggests that hop 16, 68.87.227.122, is not accepting/passing protocol 4 packets. The hostname for that host is lag-2-240-acr07.pinole.ca.sfba.comcast.net. I hate to throw you to the wolves of comcast's customer service line, but you may need to find out from them if they suddenly started filtering out inbound IPIP packets at that router. - Brian On Sat, Jun 29, 2019 at 09:50:40AM -0700, Cathryn Mataga via 44Net wrote: > Date: Sat, 29 Jun 2019 09:50:40 -0700 > From: Cathryn Mataga <cathryn(a)junglevision.com> > To: AMPRNet working group <44net(a)mailman.ampr.org> > Subject: Connecting to 44net > > I'm not connected to 44net anymore, when I ping, to me at least, my > outgoing packets look correct, but I get no response ever. > > I'm trying to put together as much as I can.

Vultr.com - "Invalid BGP RPKI Entries"
by Brian Kantor 07 Jul '19

07 Jul '19

If you are one of the 35 or so people who received a letter from support(a)vultr.com informing you that there is a problem with your subnet RPKI settings, feel free to ignore and discard it. There is nothing wrong with your RPKI settings. In fact, most of you don't have any RPKI settings at all. Maybe someday. Vultr has a problem with their audit software which has been sending out false alarms. There appears to be no cause for concern. - Brian

Cathryn; I'm also on Comcast. To let you know in my 4 year battle with them, it took me contacting Cisco direct to find out what the problem was. They simply deploy broken CPE units to the end user by design. What's probably happening is that they disable certain menu functions which allows them to say they don't filter certain things, however the natural behavior of the CPE will still filter. There's 2 solutions available.

Old Files

I apologise in advance if this message is misplaced, but I've seen some names/callsigns on the list that go back far enough to possibly have what I'm looking for. Some weeks back I performed some hardware decode comparisons for old packet hardware - MFJ1270B and Tiny2 mk2 TNCs, serial port Baycom modem (TCM3105 based), Baycom USCC>4 card with 1x9k6, 1xAMD7911 and 2xTCM3105 modems, a YAM modem, and some relatively new hardware, the TNCX and Byonics TT4) - with Dire Wolf software decoding, with some surprising results, except for the YAM. Try as I might I couldn't get the YAM to rx data at 9k6, but I was able to tx to the Baycom 9k6 modem which decoded packets. That was after I added external, 5V powers supplies because the comport wasn't up to the task (-5V/+2.8V)! The YAM won't tx or rx at 1k2. I know the YAM is old - about 1998 - and there isn't much information beyond what little I already had for the unit, which was capable of two-way communication (over wire) with the Baycom many years ago, so I know it "did" work. The Wayback Machine provided nothing useful. My request is for any information pertaining to the YAM, and in particular, any mcs configuration files for Linux. I have yam96v13, yam17 and yam1k2b5. My fading memory seems to recall documentation pertaining to faults and modifications, so that could also prove useful .. if any still exists. Thank you for your ears (or is that eyes?) Ray vk2tv

NPR (New Packet Radio) : new firmware with 56kBaud and 120kBaud
by f4hdk 19 Jun '19

19 Jun '19

Hello. I have updated the firmware of my NPR (New Packet Radio) project with 2 expected features, mainly for America: * New modulations (11, 12, 20, 21) for lower datarates, lower bandwidth. Symbol rates: 56kS/s (complies with FCC) and 120kS/s. You now have the choice between 9 modulation parameters, in order to adapt to lots of situations and needs. * Frequency range extended to 420-450MHz instead of previously 430-440MHz I have updated all the documentation accordingly. https://hackaday.io/project/164092-npr-new-packet-radio/ Several people here expected these features. I hope you will enjoy it! 73, Guillaume F4HDK

Indeed, I have (not so fond) memories of trying to convince some carriers (usually tier 2 / wannabe tier 1’s) that they needed to update their filters so our customers could reach their networks.

IRR Entries for BGP Filtering
by Jonathan Lassoff 19 Jun '19

19 Jun '19

Hello 44Net friends -- I'm operating a BGP-announced subnet of 44/8 for some paging and SDR experiments, and with some new access to other facilities, I'm looking into adding some geographic redundancy for my network, setting up an ASN, and beginning some public peering. However, what I am coming to discover is that Brian's LOA only gets me so far... :) Many networks in Europe are doing proper per-peer prefix filtering, constructed from IRR data in various registries. I would like to get my 44/8 prefix listed in one of these registries with my ASN listed, so that I can get all this automatic filtering working. Generally, most networks seem to be using the RIR-provided IRR registry for this data, which for us in the US and with AMPR would be ARIN. There are also some commercial IRR databases. https://www.radb.net/ seems to be the most-widely mirrored, but it costs ~$500/year to use. As this is just a hobby project for me, it's difficult to justify the costs of a commercial registry. Might it be possible for AMPRNet users to use ARDC's ARIN accounts to list some "inetnum" IRR data for our prefixes? Depending on the outcome, maybe this would be some useful information to list on the FAQ in the Wiki. Thanks, jof
