Question re. operator tools - somewhere betwixt fast failover and TE
by Matthew Nance Hall 05 Aug '22

05 Aug '22

Hello, I'm Matthew Nance-Hall (Matt), a PhD Candidate at the University of Oregon working with Prof. Ram Durairajan (UO), Prof. Paul Barford (UW-Madison) and Prof. Klaus-Tycho Foerster (TU Dortmund). I was hoping someone could shed operator perspective on a research question we're exploring. We're interested in the timescales and mechanisms used to adjust data paths and wondering where gaps might exist between traffic engineering (TE), fast fail-over, and routing. We're specifically curious about spatio-temporal characteristics where gaps might exist. For example, the topological scope of an event (congestion or outage) and the timescale for adjustments to be made. I'm aware there are operator tools such as fast fail-over and TE for making changes confined to single links or across the whole network but wonder if there is a place for events that have broader scope (beyond a single link but less than the whole network) where new inquiry and exploration would be welcome. Thank you, Matt

2 Byte ASNs??
by Justin Wilson (Lists) 05 Aug '22

05 Aug '22

Whats the availability of two byte asns look like? Anyone able to obtain one recently? I have a network that is all Mikrotik and the route targets are messing with them. They can’t use communities with their 4 bytes asn. It’s one of those it really isn’t a big deal but I thought I would ask.

Cogent help needed
by Chuck Church 05 Aug '22

05 Aug '22

Can anyone from Cogent hit me up off-list? Having an issue in South America getting packets to our site in Brazil. Traceroute shows route though a Cogent router, then RFC1918 replies. So not sure if problem is Cogent or a peer of theirs. Two hosts in the 177.10.168.124/30 are acting differently. Thanks, Chuck

NANOG List posts and DMARC
by Jared Mauch 03 Aug '22

03 Aug '22

Can someone flip the option in Mailman for DMARC please, it’s problematic as if one posts and does DMARC and has feedback on, our messages are possibly rejected, and the feedback from a post is quite large. Not sure who manages it anymore these days. - Jared

Allegedly Tier 1s in Wikipedia
by Rubens Kuhl 02 Aug '22

02 Aug '22

Hi. Looking at the article on Tier 1 networks, I found one that I know for a fact that pays for some transit (12956) and some I usually don't associate to Tier 1 status, like 6762. Is there a list of such transit relationships by those bragging about being Tier 1 ? Rubens

FEC AO 2022-14
by William Allen Simpson 02 Aug '22

02 Aug '22

https://www.washingtonpost.com/politics/2022/07/29/republican-fundraising-g… -------- Forwarded Message -------- Subject: AO 2022-14 Date: Sun, 31 Jul 2022 12:03:20 -0400 From: William Allen Simpson <william.allen.simpson(a)gmail.com> To: ao(a)fec.gov https://www.fec.gov/data/legal/advisory-opinions/2022-14/ * Opposing the proposal as written. * Permitting unsolicited electronic bulk mail advertisements from political actors is an involuntary contribution from Gmail users. Google's statement that the Gmail service is "free" for its users is inaccurate. As Google admits against interest, Gmail users are subjected to advertisements and also may subscribe to the service. Moreover, data transmission and storage costs are significant. Political electronic bulk mail is distinguishable from physical bulk mail. Electronic mail is receiver pays (via advertisements or subscription). Physical mail is sender pays (via stamps or permits). Therefore, this is not without cost to the recipient. Google reports an immense profit. It is undesirable and unseemly to pay (via advertisements or subscription) and then receive more bulk advertisements. Support a requirement that all political and other bulk senders be "opt-in". Support that that for every bulk message: The requestor must meet reputational thresholds and ensure that their messages are secure, filterable, and follow best practices for the user experience, including for example: (i) “one-click” unsubscribe, which enables a user to efficiently opt out of future communications; (ii) approving and following unsubscribe requests within 24 hours, which respects the user’s choice; and (iii) ensuring that all links in the message can be scanned by Google for phishing and malware detection, which helps to protect the user from harmful content. At our residence, the US mailbox is positioned near the recycling bin. Bulk mail generally goes directly into recycling without being viewed. Sadly, receiver has to pay for recycling (via taxes). Likewise, we expect unsolicited electronic bulk mail to go directly to recycling (the spam folder is automatically deleted, recycling storage). This is a helpful reduction in user data transmission and storage costs. --- I have been a Gmail user for many years. I am also a Google Fi customer. Don't be evil.

Tool for virtual networks
by Casey Deccio 30 Jul '22

30 Jul '22

Dear colleagues, I've been developing a tool for building and experimenting with virtual networks, primarily for use with teaching network protocols. It's an active work-in-progress, but I thought it might be time to reach out to NANOG in case anyone else might find it useful and/or might have feedback to offer. Here is the code: https://github.com/cdeccio/cougarnet It includes layer-2 switches, VLANs and trunking, and routers, all using Linux processes in their own namespaces as network "nodes". It was inspired by mininet (https://mininet.org) but it was developed from scratch to meet different needs. The README has additional information. If you install and run the code, *please* do it in a *virtual machine*. At this point, it requires superuser capabilities to run things like "ip link", "ip addr", and "sysctl", among other things, using sudo. Much on the to-do list, but it meets my immediate needs. Just wanted to share in the mean time. Cheers, Casey

Sigh, friends don't let politicians write tech laws
by Michael Thomas 30 Jul '22

30 Jul '22

https://www.congress.gov/bill/117th-congress/senate-bill/4409/text?r=9&s=1 the body of the proposed law: "(a) Conduct prohibited.— (1) IN GENERAL.—It shall be unlawful for an operator of an email service to use a filtering algorithm to apply a label to an email sent to an email account from a political campaign unless the owner or user of the account took action to apply such a label." where to even start with how bad this would be. thanks for the heads up from Anne Mitchell Mike
