Github/gist list of modern telemetry/networking polling tools
by Drew Weaver 12 May '22

12 May '22

Hello, If you guys are like me I find something that works and I just stick with it. Now that we're getting to a place where we can re-tool some of our monitoring and telemetry for our network I am looking for information/recommendations on new tools. Specifically I am looking a list of NMS, SNMP poller/grapher, sflow/netflow cap/dump tools that people are enjoying. I know a lot of times people post lists of tools over on github or a gist so I am just wondering if anyone has any lists for this that they like? Thanks, -Drew

Newbie x Cisco IOS-XR x ROV: BCP to not harassing peer(s) and upstream(s)
by Pirawat WATANAPONGSE 11 May '22

11 May '22

Dear Guru(s), We used to run our ‘Gateway Router’ with ROV turned on. Then, we “upgraded” it to a Cisco NCS-55A1 (5500 Series) running IOS-XR just a few weeks ago. Consequently, during my rummage through Google for a (the?) best (ROV) configuration template for the new router, I found a tutorial by Philip Smith [Reference: https://www.bgp4all.com/pfs/_media/workshops/02-rpki.pdf, Slide #55] which cautioned me of Cisco IOS-XR essentially “harassing” all peers and upstreams with ‘Route Refresh’ whenever there is a VRP change. The tutorial advised turning on ‘Soft Reconfiguration’ to help with the problem. On the one hand, we have a very special relationship with our upstream [they’re kind of community transit provider; we have an in-kind stake in them as well], so we obviously don’t want to cause them grievances [their grievance is our grievance]. On the other hand, we can't afford to just throw away a newly bought gateway and buy a new one. So, here goes the question: Is setting 'Soft Reconfiguration' enough for me to keep ROV running? If not, is there any other solution? Or am I screwed anyway? I would very much appreciate clarification and pointer(s) to the solution(s). Thank you in advance for the help, Pirawat.

Court orders for blocking of streaming services
by Joe Greco 09 May '22

09 May '22

Greetings - Recently, a court issued a troubling set of rulings in a default decision against "Israel.TV" and some other sites. https://storage.courtlistener.com/recap/gov.uscourts.nysd.572373/gov.uscour… https://storage.courtlistener.com/recap/gov.uscourts.nysd.572374/gov.uscour… https://storage.courtlistener.com/recap/gov.uscourts.nysd.572375/gov.uscour… While the issue of domains being confiscated and being handed over to a prevailing plaintiff for an international domain with no obvious nexus to the United States by a United States court via orders to companies that happen to be in the United States is a bit of a concerning issue, that's not operationally relevant. What's more concerning is that the ruling includes an expansive clause B, "Against Internet Service Providers (ISPs):" IT IS FURTHER ORDERED that all ISPs (including without limitation those set forth in Exhibit B hereto) and any other ISPs providing services in the United States shall block access to the Website at any domain address known today (including but not limited to those set forth in Exhibit A hereto) or to be used in the future by the Defendants (.Newly-Detected Websites.) by any technological means available on the ISPs. systems. The domain addresses and any NewlyDetected Websites shall be channeled in such a way that users will be unable to connect and/or use the Website, and will be diverted by the ISPs. DNS servers to a landing page operated and controlled by Plaintiffs (the .Landing Page.) which can be reached as follows: This expansive clause basically demands that ISP's implement a DNS override in recursers, which may be dubiously effective given things such as DNSSEC and DNS-over-HTTPS complications. This is not an insignificant amount of work to implement, and since they have not limited the list to big players, that means us small guys would need to do this too. Perhaps more worryingly is the clause "by any technological means available," which seems like it could be opening the door to mandatory DPI filtering of port 53 traffic, an expensive and dicey proposition, or filtering at the CPE for those who run dnsmasq on busybox based CPE, etc., etc. This seems to be transferring the expense of complying to third parties who had nothing to do with the pirate sites. Complying with random court orders where there isn't even a formal notice that there's been a court order is problematic. I would guess that the 96 ISP's listed in the order are going to receive a formal notice, but by what mechanism does the court think that a small service provider would even be aware of such an order? What happens with respect to the "Newly Detected Websites"? What mechanism exists here? Who is going to pay for the costs? And how is this practical when this scales to hundreds or thousands of such rulings? It seems to me like the court overstepped here and issued a ruling that contained a lot of wishful thinking that doesn't reflect the ability of miscreants on the Internet to just rapidly register a new domain name with a new fake credit card. Certainly it is trivial to host the actual websites well out of legal reach of US courts, and with domain registrars without US presence. This leaves those of us in the network operations community in the position of shouldering costs to comply with a court order, but without a clear mechanism to continue to be in compliance. This could become a full time job, if the defendants want to play the game right. "israel.tv"? "1srael.tv" (with a "1" or "L" for the first letter, etc). Is anybody here considering recovering compliance costs from the plaintiffs? ...

I’m a Minnesotan, the land of Powder Milk Biscuits, and thus an honorary Canadian. I can attest that poutine is indeed wonderful, and I would say essential to withstand the viciously cold northern winters. It originated in Quebec, and is still very popular there, and also throughout Canada. Importantly, poutine is a critical infrastructure component for network administrators. I would go so far as to say that it is the only food that can serve all North American Network Operators as universal sustenance. https://www.britannica.com/topic/poutine “It has become a symbol of Québécois and Canadian cuisine and culture.” -mel On May 8, 2022, at 7:31 AM, Laura Smith via NANOG <nanog(a)nanog.org> wrote: ------- Original Message ------- On Friday, May 6th, 2022 at 13:59, J EMail <70ford500(a)gmail.com> wrote: poutine should be on this list.

Announcement of Experiments
by Alexandros Milolidakis 07 May '22

07 May '22

Hi NANOG, We are a group of researchers from the KTH Royal Institute of Technology (Sweden). Starting from May 9 until May 31, we plan to conduct a research study involving AS-PATH poisoning to measure how reliable route collectors are to report BGP poisoned routes. We will use the PEERING Testbed [1] to announce the following two prefixes: - 184.164.236.0/24 - 184.164.237.0/24 for our AS-path poisoning experiments. The above experimental prefixes do not host any production services, hence user traffic will *not* be affected. Furthermore, we will always start the AS-PATH with the correct ASN as the origin. Lastly, to keep the AS-PATH short, we will announce no more than four Poisoned ASNs per announcement. The frequency of the announcements will not exceed four per hour. If, for any reason, you want to opt out from us using your ASN for our experiments, you can do so in the following form before May 9: https://forms.gle/ZvZaodndPhCqMvR89 I remain at your disposal for any questions. Best regards, Alexandros [1] https://peering.ee.columbia.edu/
