Spoofer Report for NANOG for Sep 2019
by CAIDA Spoofer Project 08 Oct '19

08 Oct '19

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. This report summarises tests conducted within usa, can.

dns cache beyond ttl - viasat / exede
by Mike 08 Oct '19

08 Oct '19

Hello, I am moving a number of web sites from one colo to another, re-numbering them in the process, and I have run into an interesting issue I'd like to solicit feedback on. My dns TTL's are all 300 seconds, and I have noticed that once I update the A records with the new addresses, most (but not all) web clients begin using the new address within 5 minutes or so. However, there is a persistent set of stragglers who continue accessing the site(s) on their old addresses for far in excess of this - up to a week in fact. And, what I have noted, all of these clients have something in common - they all appear to be satellite users of viasat/exede. This is based on whois lookups of the ip addresses of the clients. Note, I am NOT expecting 'turn on a time' - just looking for clients to refresh within a reasonable time. I am wondering if perhaps this is due to some kind of (known?) bug in the embedded dns cache/client in the client satellite modem, or if there is another plausible explanation I am not seeing. It compounds my problem slightly since I have to continue running the web sites at both the old and new addresses while these things time out I guess and it's just inconvenient. Thanks. MIke-

Automated Abuse Reports
by Matt Corallo 08 Oct '19

08 Oct '19

How do people view the automated generation of abuse reports? I’ve seen lots of (understandable) moaning about large providers not handling abuse reports, and lots of (understandable) suggestions that ARIN test for the reachability of abuse contacts. On the flip side, I run a Tor exit node (as well as bridge nodes, which appear to be used exclusively by Chinese, Russian, and Iranian IPs, indicating Tor is, contrary to popular belief, used in large part for its intended purpose). Because people seem to include “you tried three to log in three times and got the password wrong” in their definition of abuse, I’ve had to provide bogus abuse contacts (and include actual abuse comments in the comments section). I’ve tried reaching out to other operators suggesting that they cut it out, as they are the reason many operators do not provide functional abuse contacts, usually with a response of “so stop attacking my serverz!!!1one”. Is it time to have ARIN add a “abuse contact available only after captcha” option? Matt

This made it possible to duplicate all traffic to destined to one station to appear on two (maybe more?) ports. You might try this also if you have an unused and available switch. John

This DNS over HTTP thing
by Jay R. Ashworth 07 Oct '19

07 Oct '19

I've been embroiled in my first house-move in 28 years, and just got back to the table. I don't see any threads here about whatever this thing-which- appears-to-me-to-be-a-monstrosity; has it been discussed here and I missed it? Is there an official name for it I should be searching for? Is it in fact not a monstrosity, and I'm just not smart enough? :-) Cheers, -- jra -- Jay R.

for some months, our border routers log attempts to connect from the outside using a source address that is internal to my network. e.g. Oct 3 06:48:12 r0 7833: Oct 3 06:48:11.267: %FMANFP-6-IPACCESSLOGP: SIP0: fman_fp_image: list serial-in4 denied udp 147.28.0.223(3465) -> 147.28.0.222(53), 1 packet some days, we see a *lot* of this. anyone else seeing similar? randy
