08 Apr '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.

Hi NANog community, In Sydney ASX datacentre, I am looking to perform an iperf test from one of my transmission equipment. For that purpose I am looking to rent a server (2 weeks or 1 month)+ installation in the datacentre with following specs: - Capable of running a 500M iperf 2.0.9 test - Network connectivity in SMF (100BASE-LX) preferred but we can accommodate copper Would one of you able to provide such services and provide me a quote for it? Thanks in advance for your feedback, Please contact us me and Eymeric in cc outside the ML if you can get any proposal Best Regards -- Alexandre

Re: COVID-19 vs. our Networks
by Scott Weeks 07 Apr '20

07 Apr '20

We do about 70-80Gbps at peak over the external BGP links we have and I am not seeing a large increase nor am I seeing it spread out over time. We're an eyeball network plus some really large customers. Anyone else seeing something different? We're now into the 3rd day, so I thought I'd see something change by now. scott

IS-IS on FRR - Is Anyone Running It?
by Mark Tinka 07 Apr '20

07 Apr '20

Hi all. So I finally decided to start messing around with FRR for a native IS-IS deployment for some of our FreeBSD-based Anycast services. I hit an issue that I posted to the FRR list that hasn't progressed beyond identifying a bug: 2020/03/21 03:12:36 ISIS: isis_send_pdu_bcast: sock_buff size 8192 is less than output pdu size 9014 on circuit em0 2020/03/21 03:12:36 ISIS: [EC 67108865] ISIS-Adj (1): Send L2 IIH on em0 failed This is being addressed here: https://github.com/FRRouting/frr/pull/6066 But my main question was if there was a command or setting in zebra.conf and/or isisd.conf that I can use to define the MTU IS-IS should use to set itself up, rather than being informed by what the interface currently runs at. I've tried everything that is documented as well as stuff that isn't, but nothing is accepted or recognized. Either no one runs IS-IS on FRR, or much of the implementation is still being developed and/or hasn't been tested in the wild, i.e., no traction. I'm hoping there is someone on this list that has played with IS-IS on FRR to point me in the right direction. The setup is FRR 7.3 on FreeBSD-12.1. Thanks. Mark.

Command and Control Centres | COVID-19
by Scott E. MacKenzie 06 Apr '20

06 Apr '20

All, This question has arisen and I was wondering if I could request some feedback from the community. We operate a 24x7x365 Command and Control Centre that provides mission critical services (Security Operations, Network Operations, and Enterprise Management) as does many on this list. How many on the list have sent all personnel home using work from home practices and home many have opted to run skeleton crews while implementing tight social distancing restrictions? How many are operating status quo? We are trying to find a balanced position and I was wondering what is the communities position on this topic? Scott

FCC and FTC Demand Cut-Off Robercallers of Coronavirus Scams
by Sean Donelan 06 Apr '20

06 Apr '20

A sternly worded, finger-wagging press release. https://www.fcc.gov/document/fcc-ftc-demand-gateway-providers-cut-covid-19-… [...] The FCC’s Enforcement Bureau and FTC’s Bureau of Consumer Protection wrote to three gateway providers that are facilitating these scam COVID-19-related robocalls: SIPJoin of Suffolk, Virginia; Connexum of Orange, California; and VoIP Terminator/BLMarketing of Lake Mary, Florida. The companies have been identified by the Traceback Group, a consortium of phone companies that help officials track down suspect calls, managed by the trade association USTelecom. The Commissions also wrote to USTelecom to ask its members to begin blocking calls from these providers if the flood of robocalls is not cut off within 48 hours.

IS-IS looks at MTU in order to work, and if nothing is manually set, it infers the MTU from the physical interface over which it is enabled. While the current IS-IS implementation in FRR is buggy to the extent that it does not assume MTU can be larger than 8,192 bytes, that does not prevent an operator from telling it what MTU it should use for IIH messages, provided the physical interface can support it. Suffice it to say, I already have a number of Sysctl and kernel knobs in FreeBSD to tune the system for the Anycast services we run on them. I'd be disinclined to mess about with that as I don't think it has any bearing on an over-the-top service such as IS-IS. Quagga runs well (OSFP though, I'll admit), and I'll keep looking for answers on IS-IS in FRR until it stops making sense. Mark.
