Comcast contact sought
by Al Whaley 25 Sep '23

25 Sep '23

I am looking for a senior contact at Comcast. I have been trying to assist someone with a business connection that runs a server farm. Recently the business cable modem started to short-stop port 53 for UDP and TCP. Apparently, a transparent DNS proxy somehow got activated and all outbound traffic to any IPv4 or IPv6 address is intercepted and handled by the modem – or not handled. Sadly, the proxy is stupid and a) ignores the intended destination address, and b) drops things it doesn’t know about, including any AXFR / IXFR and other more esoteric traffic, normal for DNS server installations, but not used by the public. The DNS servers are not able to do work, e.g. act as secondaries. I know others in the same configuration with servers that have been lucky and not had this ‘feature’ activated, but I have found several references on forums where people have been caught by this and unsuccessful in reaching anyone in management, so it is a known problem. Comcast doesn’t allow customer supplied DOCSIS modems with multiple fixed IPs. Other avenues exhausted as well. I’m hoping someone at Comcast can disable this. Attempts to go through customer service… well we all know where that ends up. Escalations just don’t go to anyone technical or interested. regards Al Whaley Sunnyside Computing, Inc.

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.)
