Bird Router Appliance projects
by Douglas Fischer 05 Nov '20

05 Nov '20

I'm deploying some Linux based routers with BIRD as the routing daemon. -> Yep, Bird is a specific requirement for this project. But is taking me to much time to adjust(and in the future keep it running good) the basic like, sysctl adjustments for routing and performance on that, ssh/snmp and security tunning for that. So I'm looking for something a bit more "almost ready". I remembered BSRP(which has a recent release with support to Bird 2.0.7). But I'm looking for something in the Linux world. P.S.: Actually, I believe that what better describes my wishes would be: Something like Vyos or Danos, with all the complementary resources of a router like: SNMP, Netflow, SSH, Telnet, Interfaces/Address setting... But with Bird instead of FRR. -- Douglas Fernando Fischer Engº de Controle e Automação

Asus wifi AP re-writing DNS packets
by Anurag Bhatia 04 Nov '20

04 Nov '20

Hello, Wondering anyone from Asus here or anyone who could connect me to the developers there? Using Asus RT-AC58U in Access Point(AP) mode and expect it to simply bridge wired with wireless but seems like it's re-writing DNS packets source as well as the destination. 1. DNS port 53 traffic going out, the source is re-written with the management IP of the AP on the LAN. So virtually all DNS traffic hits the router from the (management) IP of the Asus AP instead of real clients. 2. If I define DNS as x.x.x.x on DHCP, the Asus AP picks that up and re-writes destination to x.x.x.x and hence even if any client uses y.y.y.y, the packets are simply re-written. I see the rule in iptables on Asus AP. All these issues give an idea that someone created AP mode (besides regular routing mode) and missed to disable the DNS related NATing features in the AP mode. So far my discussions with their support have been going quite slow and would greatly appreciate if someone could connect me to right folks in there so they can release a firmware fix for it. Thanks. -- Anurag Bhatia anuragbhatia.com

Mellanox / Cumulus
by Bryan Holloway 04 Nov '20

04 Nov '20

Curious to hear if the community has had any real-world experience using Mellanox/Cumulus (nVidia) for L2/L3 things outside of the datacenter. Like other vendors, notably Arista, they seem to be trying to move out of the datacenter and target SPs and the layer 3 market. Personally, I think Arista has worked out most of the kinks over the last few years, and we've been happy with their L3 solutions (e.g., the 7280s) While Mellanox's chipset is intriguing, I get a sense of feature-itis from their marketing. (BGP, OSPF, NAT, we do it all etc.) No IS-IS support, I'm told ... Anybody using these in production in an SP environment? And if so, any opinions, good or bad? Feel free to reach out off-list if you prefer. Thank you, - bryan

Microsoft is hacking my Asterisk??? O_o
by Max Tulyev 03 Nov '20

03 Nov '20

Hi All, I have just seen a number of IPs trying to brute-force my VoIP server from Microsoft network. For example, 13.90.148.133, 20.55.203.249, 40.76.244.210... Traceroute really goes to MSN. More than a half of all usual attempts to hack my Asterisk I got today, came from MSN. What is happening? Am I missed something?

Re: 100G over 100 km of dark fiber
by Jared Brown 03 Nov '20

03 Nov '20

Turns out I was wrong, again. There is at least one vendor that offers pluggable 100G QSFP28 optics that can reach 120 km with amplification. Thanks to everybody that reached out! I appreciate all the input and lessons learned. Jared ------------------------------------------------------------------------------------------------------- Hello NANOG! I need to push 100G over 100 km of dark fiber. Since there are no 100G pluggable optics with this reach (~25 dB), I have been offered coherent transport systems to solve my problem. This is all good and well, except total system costs start from high five figures. So, my question is, do I have any other options? I can't help noticing that you can break out a 100G QSFP into four 25G QSFPs. 25G DWDM systems are relatively inexpensive (low five figures), but can you make 25G DWDM go 100 km? I only need the one 100G, so I don't really need a highly scalable DWDM system. I can't put anything midspan, or if I could it would cost more than just going with a coherent system. Jared

Youtube TV Location error. Google Confirms issue but can't fix.
by Nate Burke 03 Nov '20

03 Nov '20

Anyone here from the Youtube TV side of Google? I've had a ticket open for 2 months on one of my /24 subnets getting the wrong City location. Every ticket reply from Google confirms that they see the incorrect location, They reference that it is part of a larger geo-location problem with YoutubeTV, and it's been sent to engineering. For 2 months Engineering has been 'working on a fix' with no ETA. Anyone know what this massive geo-location issue is that they reference, and when it will be fixed? Other subnets are locating correction, just this one /24, that's part of a larger block I've had for 20 years. Nate Burke Blast Communications

RSS Feed for this list?

Hi, I noticed that now the old gossamer-threads.com archives of the NANOG mailing list are redirecting to a hosting company or MSP. I used to consume these archives via RSS as it was a little easier for me than grinding through a NANOG folder. Is there any extant RSS feed for the NANOG list? Tim

FCC Announces All Of Puerto Rico To Have Access To High-Speed Broadband Service As A Result Of Uniendo A Puerto Rico Fund Nearly a Third of Locations Will Get Speeds of At Least 1 Gbps with All Other Locations Getting Speeds of At Least 100 Mbps https://www.fcc.gov/document/fcc-announces-usf-support-high-speed-broadband… WASHINGTON, November 2, 2020—The Federal Communications Commission’s Wireline Competition Bureau today announced that funding through Stage 2 of the Uniendo a Puerto Rico Fund will result in all locations in Puerto Rico having access to fixed broadband service with speeds of at least 100 Mbps. And nearly one-third of those locations will have access to fixed broadband service with speeds of at least 1 Gbps. Two winning applicants in the Uniendo a Puerto Rico Stage 2 Competitive Process submitted bids for $127.1 million in funding over 10 years covering more than 1.2 million locations through a competitive process that awarded support for fixed voice and broadband services based on the weighting of price and network performance, including speed, latency, usage allowance, and resiliency. Liberty Communications has committed to offering service to over 914,000 locations, and Puerto Rico Telephone Company will offer service to over 308,000 locations.
