Strange connectivity issue Frontier EVPL
by Jay Hennigan 11 Nov '20

11 Nov '20

We have a strange issue that defies logic. We have a NNI at our POP with Frontier serving as an aggregation circuit with different customers on different VLANs. It's working well to several customers. Bringing up a new customer shows roughly half of the IP addresses unreachable across the link, as if there's some kind of load-balancing or hashing function that's mis-directing half of the traffic. It's consistent, if an address is reachable it's always reachable. If it's not reachable, it's never reachable. Everything ARPs fine. The Frontier circuit is layer 2 so shouldn't care about IP addresses. Frontier tech shows no trouble. They changed the RAD device on-premise. We've triple-checked configurations, torn down and rebuilt subinterface, etc. with no joy. Any suggestions? -- Jay Hennigan - jay(a)west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV

Technology risk without safeguards
by Suresh Kalkunte 11 Nov '20

11 Nov '20

Hello, I believe the below described method of causing intentional (1) damage to equipment in data centers and (2) physical injury to a person at the workplace is on-topic for the NANOG community, if not, I look forward to your feedback. As a software developer who has subscribed to the NANOG mailing list for a number of years, I post this note relying on intellectual honesty that I have had the opportunity to observe since 1996-97. The below described technology risk is applicable to computing/communication equipment rendered vulnerable by Intentional Electromagnetic Interference (jamming an electronic device) and the risk of health sabotage affecting people (jamming a human) managing the Internet infrastructure enabled by intentional application of powerful radiofrequency fields (RF) emitted by re-purposed components salvaged from a kitchen heating appliance (Magnetron) or from an outdoor high gain/power Line of sight transceiver (unidirectional microwave radio) which has a harm causing range up to 25 meters (estimated using a Spectral Power Density calculator like www.hintlink.com/power_density.htm) This risk from mis-application of powerful RF is from human operated or IoT apparatus** with an avenue of approch from (a) subterrain placement aided by a compact/mini directional horizontal drilling machine (eg. principle of placing a stent in the heart) and/or (b) strategic placement in an obscure over-surface location to maximize negative impact on the target of opportunity. With building materials or ground offer insufficient* protection to block the passage of powerful RF and the absence of diagnostic/forensic tests to detect biomarkers expressed post-overexposure to harmful RF (combination of RF frequency, Spectral Power Density/Specific Absorption Rate incident on a person and duration of exposure), intentional damage to electronic equipment and people is at present unrestricted. The purpose of bringing this method of exploting technology to your attention is with an interest to build the momentum for ushering in the much needed safeguards in this context. Thanks.

CNAME records in place of A records
by Dovid Bender 09 Nov '20

09 Nov '20

Hi, Sorry if this is a bit OT. Recently several different vendors (in completely different fields) where they white label for us asked us to remove A records that we have going to them and replace them with CNAME records. Is there anything *going around* in the security aranea that has caused this?

Spoofer Report for NANOG for Oct 2020
by CAIDA Spoofer Project 08 Nov '20

08 Nov '20

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can. Inferred improvements during Oct 2020: ASN Name Fixed-By 14860 AS-SMARTCOM 2020-10-15 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Oct 2020: ASN Name First-Spoofed Last-Spoofed 54825 PACKET 2016-04-15 2020-10-07 46562 TOTAL-SERVER-SOLUTIONS 2016-04-26 2020-10-08 209 CENTURYLINK-US-LEGACY-QWEST 2016-08-16 2020-10-30 40676 AS40676 2016-08-29 2020-10-08 6128 CABLE-NET-1 2016-09-03 2020-10-31 20412 CLARITY-TELECOM 2016-09-30 2020-10-31 6181 FUSE-NET 2016-10-10 2020-10-29 14971 PINETEL 2016-10-21 2020-10-31 11427 TWC-11427-TEXAS 2016-10-21 2020-10-21 32440 LONI 2016-11-03 2020-10-26 12083 WOW-INTERNET 2016-11-09 2020-10-31 20473 AS-CHOOPA 2017-01-08 2020-10-27 9009 M247 2017-01-10 2020-10-08 25623 CISN2 2017-03-13 2020-10-26 63296 AWBROADBAND 2017-09-01 2020-10-27 546 PARSONS-PGS-1 2017-11-20 2020-10-05 33452 RW 2018-09-19 2020-10-31 20448 VPNTRANET-LLC 2018-09-20 2020-10-22 197706 KemiNet 2019-03-01 2020-10-08 8047 GCI 2019-04-11 2020-10-30 45671 AS45671-NET-AU 2020-08-18 2020-10-08 199524 GCORE 2020-09-02 2020-10-08 132372 GBNETWORK 2020-10-08 2020-10-08 13739 DATACENTER-IP 2020-10-08 2020-10-08 395092 SHOCK-1 2020-10-10 2020-10-31 3491 BTN-ASN 2020-10-18 2020-10-28 23155 HTC-NET 2020-10-18 2020-10-18 63125 WICKED 2020-10-26 2020-10-26 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=usa,can&no_block… Please send any feedback or suggestions to spoofer-info(a)caida.org

BGP Peers Data modeling schema
by Douglas Fischer 06 Nov '20

06 Nov '20

I'm designing a tool for provisioning configurations for an ITP and his Peers. The idea is that based on that, all the configs to all the involved components configurations to be deployed based on that source of data. I'm Talking about Routers, BMP, SNMP tool(Ex.: Zabbix), etc... But, once again, I'm feeling that I'm reinventing the wheel. I'm pretty sure that someone else has already suffered from that. I search for a bit, and I didn't find anything... But with this gray area between developers and network operators, I'm not sure if I'm looking at the right place. I even tried to look at http://schema.org but didn't find anything related to networks and BGP there yet. So, anyone could point me in the right direction? -- Douglas Fernando Fischer Engº de Controle e Automação

Verizon or Verizon Wireless contact
by Jeff Shultz 05 Nov '20

05 Nov '20

Looking for a contact with a clue at Verizon/Wireless who can help me with a problem, to wit, Verizon is blocking calls from our landline customers to one of their local wireless prefixes. We've got the error that the Verizon switch gives ("Welcome to Verizon your call can not be completed as dialed. Announcement for switch 3 0 dash 2.) Any publicly available numbers or tech support just leads me in circles. I figure if I keep at it long enough, I'll collect the whole set of their toll free numbers... but I'd prefer not to.

Bird Router Appliance projects
by Douglas Fischer 05 Nov '20

05 Nov '20

I'm deploying some Linux based routers with BIRD as the routing daemon. -> Yep, Bird is a specific requirement for this project. But is taking me to much time to adjust(and in the future keep it running good) the basic like, sysctl adjustments for routing and performance on that, ssh/snmp and security tunning for that. So I'm looking for something a bit more "almost ready". I remembered BSRP(which has a recent release with support to Bird 2.0.7). But I'm looking for something in the Linux world. P.S.: Actually, I believe that what better describes my wishes would be: Something like Vyos or Danos, with all the complementary resources of a router like: SNMP, Netflow, SSH, Telnet, Interfaces/Address setting... But with Bird instead of FRR. -- Douglas Fernando Fischer Engº de Controle e Automação
