Anyone from Google Global Cache ?
by George Toma 21 Mar '23

21 Mar '23

Hello, Is there someone on this list from the Google Global Cache program (GGC) who could contact me off-list? If so I would greatly appreciate that. I would need a favor to get some information and look up a case because the responses to the tickets in the ISP portal I am getting are not giving me any meaningful answers. Thank you Regards George Toma

Looking for someone at ipligence and/or Washington Gas
by Glenn McGurrin 21 Mar '23

21 Mar '23

I'm recently become a customer of Washington Gas but their website won't let me see anything claiming I'm in the Netherlands and so they are blocking me. I'm not sure how the geolocation data got screwed up, as far as I can tell this IP block has never been there and every geolocation provider except for ipligence shows it in pretty much the right spot near Washington DC. Phone call to Washington Gas says email their support, their support has an auto reply saying they will get back to me but never does, I've just send the 3rd email there, the first two being the 17th and 23rd of February, so the 24-48 hours their autoresponder claims is clearly a joke. I've also submitted a contact to ipligence as they seem to be the geolocation provider in use as they are the only one with the bad geolocation data and it matches what Washington Gas claims, but no response there either and their site still shows the bad data more than a month later. I've added the one person I could find at Washington Gas via searching around to the second and third requests but it seems no one is even looking at their email and they will not help via the phone saying it's a different department and to email, at this point I'm not sure what to do other than reach out here to hopefully find someone with a clue, try publicly calling out on twitter, and possibly file a complaint with the regulators as that seems the only way they might bother to even reply. If anyone at either company is here please contact me or if anyone has a contact at either company I can try please let me know. Thanks, Glenn

Cisco Nexus Odd sFlow Implementation
by Mike Hammett 20 Mar '23

20 Mar '23

Cisco is sending the in and out packets in their sFlow implementation on their Nexus switches. Obviously, this double counts the information. Are there solutions that process those flows and remove one of those directions? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

Verizon/Qwest single end-user difficulty vs Xfinity
by Jeff Woolsey 19 Mar '23

19 Mar '23

Verizon 5G Internet Support is not at a high-enough pay grade to assess this problem... So I'm turning to y'all. I'm trying to save $$$ and increase speed, using Verizon 5G Home Internet to replace XFinity, even though they gave me a faster modem a few weeks ago. I run both of the modems in Bridge/Passthrough mode. A friend of mine is nice enough to offer some offsite backup space, and I use rsync over ssh to get there. He's 1500 miles away. He uses a non-standard ssh port (keeps the doorknob twisters away). This sort of thing has been working without difficulty over Xfinity (my end) for years. He also changed his connection almost a month ago now, to Qwest, I believe. I try the same thing over Verizon [1] and ssh always times out, no response. We are also NTP peers, and that doesn't work well over Verizon either. ICMP traceroutes and pings succeed. UDP traceroutes do not get any further than 207.109.3.78 (last hop before destination) . Not every traceroute offers TCP, but MacOS does, and nothing responds to any of that, even at the usual ssh port. UDP traceroutes to either port behave like an ordinary one, which it is. Since I can get there via xfinity, I can traceroute, ping, but not ssh back through Verizon. I also set up an incoming (xfinity) port from the same non-standard ssh port forwarding to regular ssh on a different system on my LAN, and when I ssh -p <port> that from Verizon (even cellphone data), I get that other system, and that works fine. The 207... router is not in that path. I can also ping the Verizon connection from Xfinity (and vice versa). Go figure. [1] This same difficulty occurs in Verizon's Looking Glass, from several different places, and other Looking Glasses (e.g. Cogent, Equinix). It also occurs on my Verizon phone data connection (not WiFi). If he were serving more stuff out of his home, this would be a bigger problem. -- Jeff Woolsey {woolsey,jlw}(a){jlw,jxh}.com first.last(a){gmail,jlw}.com Spum bad keming.

Land Mobile Radio (LMR) for Information Technology (IT) Professionals
by Sean Donelan 19 Mar '23

19 Mar '23

IT professionals are often tasked with planning, provisioning, implementing, and managing LMR networks with the assumption that all computer networks are basically the same and have the same general requirements. However, in some cases this assumption has resulted in LMR networks being inadequately provisioned, resourced, and managed or maintained. While each system is a network, significant differences between the two must be considered to address the infrastructure, planning, and lifecycle needs of typical IT networks versus the unique requirements of LMR networks. https://www.cisa.gov/news-events/news/safecom-and-ncswic-develop-land-mobil…

RFC6598 100.64/10: to bogon or not to bogon (team-cymru et all)
by Lukas Tribus 19 Mar '23

19 Mar '23

Hello, so 100.64/10 is used in CGNAT deployments requiring service providers (that is AS operators) to drop 100.64/10 on the border to other AS in BGP and in the dataplane, as per RFC6598 section #6 Security Considerations [1]. Within an AS though traffic from 100.64/10 can very well bypass CGNAT for AS local traffic to reduce state/logging. This appears to be quite common and it makes a lot of sense to me. At the same time folks like team-cymru are picking up this prefix for their bogon lists with the following description [2]: > A packet routed over the public Internet (not including > over VPNs or other tunnels) should never have an address > in a bogon range. It would be quite a bad idea to drop 100.64/10 on a firewall or servers, when legitimate traffic can very well hit your infrastructure with those source IPs. Thoughts?
