California fires: smart speakers and emergency alerts
by Sean Donelan 01 Aug '18

01 Aug '18

Has anyone heard if the smart speaker companies (Amazon Echo, Google Home) plan to include emergency alert capability? An estimate 10% of households own a smart speaker, and Gartner (well-known for its forecasting accuracy) predicts 75% of US households will have a smart speaker by 2020. Although most silicon valley tech nerds are still in the "invincible" years, were the california fires close enough to silicon valley that smart speaker developers might think an emergency could affect them. And an emergency alert capability in their smart speakers might be important?

Probably the best place to know what is going on with multicast is on the mboned list (yea that still exists): <https://mailarchive.ietf.org/arch/browse/mboned/> Second best might be the Internet2 community where a number of institutions that have always had it might still have it turned on. Though there has been only one post in all of 2018 on their list if that tells you anything. There is almost no public multicast monitoring anymore. Practically all dead. You could poke around the I2 router proxies and see what is happening on some of the last of the remaining IP multicast-enabled Internet (hint, mostly noise from odd devices that have strayed outside the local institution): show multicast routes show pim join ... I keep hearing about some research project in the deep blue sea that uses it. You might find a small amount of it out there, but I'd bet overall its usage is teeny tiny and limited to a shrinking number of networks. Turned off interdomain multicast when I returned here in 2016. John

Do you mean sent to 224/4 or literally anything with a source address of 224/4? For those that are or are considering filtering, you might also want to consider limiting IGMP at router interfaces. The only known use of IGMP past the local link I'm aware of was for mtrace tool, but allowing it can pose some danger in two forms. One is yet another DDoS reflection and amplification vector, another is a some router system and configuration disclosure. See the following for details: <https://ccronline.sigcomm.org/wp-content/uploads/2017/01/p27-sargent.pdf> In experiments I ran in early parts of that work I found that Cogent did not forward IGMP messages through its network in my tests, but this may be due to the routing hardware/software they were using at the time rather than an explicit filtering policy.

unwise filtering policy on abuse mailboxes

can we please just stop this nonsense? ip under your direct control originates sewage. you should accept reports as-is. requiring victims of your sewage to go through special contortions to report it to you is not acceptable. > ----- The following addresses had permanent fatal errors ----- > <abuse(a)psychz.net> > (reason: 550 "The mail server detected your message as spam and has prevented delivery.")

Two other significant contributing factors stem from complexity and security issues. Here are some references I'm familiar with: <https://www.nanog.org/meetings/nanog21/presentations/eubanks.ppt> <https://www.nanog.org/meetings/nanog35/presentations/kristoff.pdf> <https://www.cymru.com/jtk/tmp/secure-junos-mcast.html> The last link was briefly maintained on Team Cymru's production template section, but it looks it is now gone and like this is the last copy of it I had before it was published a few years ago.

issues through CGNat (juniper ms-mpc-128g in mx960)
by Aaron Gould 31 Jul '18

31 Jul '18

(please forgive cross-posting between jnsp and nanog.looking for anyone who could help shed light) I moved customers behind MS-MPC-128G (MX960) CGNat boundary a few nights ago. for the most part it went well. with these couple issues. please let me know what you know about this and how to fix. I don't know if it's fixed on the endpoints, or in the cgnat config or what. 1 - IPSEC VPN - Customer said the vpn connect light on cisco vpn router blinks (not connected to vpn) - I found out the vpn addresses that this cisco vpn router is trying to connect to. - I did a fix in cgnat rule stanza where all UDP 500 and 4500 traffic to that distant vpn endpoint(s) will always be natted to one and only one ip address (I did this thinking that the changing ip of the public pool assigned ip addresses for udp 500 and 4500 was possible breaking it) 2 - PS4 gaming - Customer said playing a few games (call of duty, etc) with Internet players now doesn't work. - They said the PS4 nat type is nat type 3 (strict) whereas before the moved them to cgnat, it was NAT type 2 moderate and worked. -Aaron
