Cogent BGP session more than 1 router ipv6
by Justin Wilson (Lists) 12 Jun '24

12 Jun '24

I am trying to get our Cogent rep to give us a /124 to peer on a Cogent circuit with. We have multipl routers we want to peer to a cogent transit circuit with.on. Does anyone have the magic words or a circuit ID example you are doing multiple BGP conenctions on a single circuit?

TCP-AO for BGP Peering?
by 7riw77＠gmail.com 12 Jun '24

12 Jun '24

Y'all -- Does anyone know of a survey or study showing the rate of uptake for BGP over TCP-AO? I've poked around some and asked in a few places and not found anything, but I probably missed something out there. If there's no studies, does anyone have any experiences possibly indicating BGP over TCP-AO usage they can share? :-) /r

Open source Netflow analysis for monitoring AS-to-AS traffic
by Brian Knight 10 Jun '24

10 Jun '24

What's presently the most commonly used open source toolset for monitoring AS-to-AS traffic? I want to see with which ASes I am exchanging the most traffic across my transits and IX links. I want to look for opportunities to peer so I can better sell expansion of peering to upper management. Our routers are mostly $VENDOR_C_XR so Netflow support is key. In the past, I've used AS-Stats [1] for this purpose. However, it is particularly CPU and disk IO intensive. Also, it has not been actively maintained since 2017. InfluxDB wants to sell me [2] on Telegraf + InfluxDB + Chronograf + Kapacitor, but I can't find any clear guide on what hardware I would need for that, never mind how to set up the software. It does appear to have an open source option, however. pmacct seems to be good at gathering Netflow, but doesn't seem to analyze data. I don't see any concise howto guides for setting this up for my purpose, however. I'm aware Kentik does this very well, but I have no budget at the moment, my testing window is longer than the 30 day trial, and we are not prepared to share our Netflow data with a third party. Elastiflow [3] appears to have been open source [4] at one time in the past, but no longer. Since it too appears to be hosted, I have the same objections as I do with Kentik above. On-list and off-list replies are welcome. Thanks, -Brian Links: ------ [1] https://github.com/manuelkasper/AS-Stats [2] https://www.influxdata.com/what-are-netflow-and-sflow/ [3] https://www.elastiflow.com/ [4] https://github.com/robcowart/elastiflow?tab=readme-ov-file

Webinar on LibreQos June 14rh
by Dave Taht 09 Jun '24

09 Jun '24

<blatant advert> We are doing an hour long deep dive webinar on LibreQos June 14th, courtesy of the APNIC Academy, with an astounding 196 signups so far. We are pushing multiple terabits of traffic around the world through it now, not just for ISPs, but for MDUs, post VPN processing, upstream DIY circuits, on everything from DSL to fiber. As an open source, eBPF based transparent bridge, it only takes a few minutes to install in-band, and be able to pull stats about your networks' behaviors that you've never seen before, and then apply the best shaping and bufferbloat-beating code in the world to it. Sign up here: https://academy.apnic.net/en/events?id=a0BOc000000Pgk1MAC - especially if you have been deploying fq_codel or cake, replacing brittle policers, etc, etc. We have a very popular chat too: https://chat.libreqos.io/join/fvu3cerayyaumo377xwvpev6/ PS The upcoming v1.5 release of libreqos is about 30% faster (example: pushing over 60Gbits through a $1500 Ryzen box), which is enough for 10s of thousands of customer networks on the other side of it. We have the ability to model and debloat complicated networks 8 hops deep, or along a troublesome edge, new support for emitting netflow, and quite a few other useful things in that release. and we hope to put it into beta by the end of this month, or earlier. Please come to the webinar to see the latest code, live, in production! https://github.com/LibreQoE/LibreQoS/tree/develop </blatant advert> I am in general deliriously happy with the stability, and performance of this stuff and the growth of uptake worldwide over the last 6 months, (and also watching starlink get thoroughly debloated a few months back was a real high, tho they just used fq and something codel-ly not LibreQos) Y'all are just minutes and minor CAPEX away from a vastly better internet. -- https://www.linkedin.com/feed/update/urn:li:activity:7203400057172180992/ Donations Drive.

Spoofer Report for NANOG for May 2024

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.

Comcast.net email servers - temporarily blacklisted IP Address errors
by Martin Cook 07 Jun '24

07 Jun '24

Hello NANOG, We recently started getting some complaints from customers experiencing an error when trying to access their old Comcast.net email accounts with one of their email clients (outlook tbird etc.) via POP3 or IMAP. Web based use of their email via the Comcast portal is unaffected. "ERR [AUTH] Temporarily blacklisted IP Address - try again later" These customers are previous Residential HSI subscribers of Comcast who have since moved to other internet service providers, including ours, and are still allowed to use their old email accounts. There is a web portal based method for attempting to get individual IP addresses removed from the "temporary black list". But due to the number of reports we have had in a very short period of time we believe an entire range of IP's (possibly a /17) has been blacklisted as of last Friday-ish We're having difficulty resolving this issue through Comcast customer support or the Comcast Security assurance team. So I'm looking to see if anyone from Comcast or someone who has had this issue before reach out off-list to assist with resolving this headache. **** Enjoy N91 next week for all the people attending, stop by to attend Jason Rokeach's talk on "meshrr: Hierarchical Route Distribution @ Scale w/ Kubernetes on Wednesday!" I'm sure he will have some awesome things to show everyone. Thanks, Martin Cook
