TACACS+ server recommendations?
by Bryan Holloway 24 Sep '23

24 Sep '23

Ah, the good old days when I could download the latest tac_plus code from the Cisco FTP site, compile it, and off I go. But I digress. Curious if there are any operators out there that have a good recommendation on a lightweight TACACS+ server for ~200 NEs and access-control for 20-30 folks. Nothing too special, but some sort of simple command-control auth would be nice. Open-source is fine ... we've been looking at commercial options, but they're all pretty pricey and have way more features than we need. Thank you all in advance! - bryan

what is acceptible jitter for voip and videoconferencing?
by Dave Taht 22 Sep '23

22 Sep '23

Dear nanog-ers: I go back many, many years as to baseline numbers for managing voip networks, including things like CISCO LLQ, diffserv, fqm prioritizing vlans, and running voip networks entirely separately... I worked on codecs, such as oslec, and early sip stacks, but that was over 20 years ago. The thing is, I have been unable to find much research (as yet) as to why my number exists. Over here I am taking a poll as to what number is most correct (10ms, 30ms, 100ms, 200ms), https://www.linkedin.com/feed/update/urn:li:ugcPost:7110029608753713152/ but I am even more interested in finding cites to support various viewpoints, including mine, and learning how slas are met to deliver it. -- Oct 30: https://netdevconf.info/0x17/news/the-maestro-and-the-music-bof.html Dave Täht CSO, LibreQos

8830 Complex Drive Datacenter in San Diego - Anyone Else Affected
by Norman Jester 20 Sep '23

20 Sep '23

Several carriers went down around 7am this morning, all tied to a datacenter in San Diego that has apparently shut down. Sad to see that place go, good guys ran it but there are several carriers that bit the bullet on us today due to that place closing down. Seems every one of them is grasping to get their connections migrated out and customers back online. We do not have gear there but I guess some of our carriers did. Lots of dark fiber enters there from several providers. Thank the lord for path diversity. :-) Norman Mexico Internet Exchange 619-319-7055 (I prefer WhatsApp or Text if you do too.)

Web traffic routing
by Sami Joseph 20 Sep '23

20 Sep '23

Hi, There's an online service that does fraud detection by forwarding web traffic to their platform before sending it to its destination. They claim they do it by one of two methods: 1) Traffic is routed to our Cloud via DNS for dynamic async or sync processing before being proxied to the customer’s website or API. 2) Traffic is mirrored or routed to our ] Cloud via serverless functions in Cloudflare, Fastly, Akamai, or AWS. Routed traffic is proxied to our customer’s website or API. If anyone can point me to how these two work, i'd appreciate it. Also, any potential issues related to performance. Thanks, Sam
