Network Access to and from China Mainland
by patrick＠pahem.de 16 Dec '16

16 Dec '16

Hello, I have a customer based in Europe which have a subsidiary in China (Mainland) and also do a lot of businesses with China (Mainland). Lately the customer have a lot of issues with accessing websites which are hosted outside China from the subsidiary in China and sees also a lot of delivery problems with emails send to China. The SMTP-Gateway is located in Germany and in the logs we can see timeouts during the connection to the STMP servers in China (Mainland). I suspect that the Chinese Firewall has changed it's behaviour. Have anyone else currently similar issues with communication to and from China? Thanks, Patrick

Rogers Peering Request
by Ryan Gard 15 Dec '16

15 Dec '16

Looking for a Rogers contact to get things moving on a peering request. Been trying to shout into their ear for well over a month, and haven't heard anything back. Further, PeeringDB information seems egregiously outdated as the URLs listed no longer are serviceable. Hoping this is the last ditch effort to wake somebody up in the red tower. Thanks! -- Ryan Gard

Cogent NOC
by Randy 15 Dec '16

15 Dec '16

Hi all, Anyone beyond front line support at cogento on list? Nanog is the last place I'd look for assistance but it seems support over at cogentco is not nearly what it used to be. Example MTR to cogen't own website (support doesn't utilize or understand MTR at all apparently): Host Loss% Snt Last Avg Best Wrst StDev 1. x.x.x.x 0.0% 196 0.5 11.7 0.3 186.8 35.2 2. x.x.x.x 0.0% 196 0.6 10.2 0.4 226.3 36.2 3. 38.88.249.209 0.0% 196 0.9 1.1 0.7 17.7 1.2 4. te0-0-2-3.nr13.b023801-0.iad01.atl 0.0% 196 1.0 1.0 0.8 2.0 0.1 5. te0-0-0-1.rcr22.iad01.atlas.cogent 2.0% 196 2.1 1.9 1.0 3.3 0.4 6. be2961.ccr41.iad02.atlas.cogentco. 2.6% 196 1.8 2.1 1.1 3.8 0.5 7. be2954.rcr21.iad03.atlas.cogentco. 2.6% 196 2.0 2.3 1.2 9.4 0.7 8. be2952.agr11.iad03.atlas.cogentco. 0.5% 196 2.7 2.6 1.5 6.8 0.6 9. cogentco.com 4.1% 196 2.1 2.0 1.0 16.8 1.1 Pretty much the same to anywhere. Packet loss begins at rcr22.iad01 and propagates all the way down the line. Worse during peak hours, gone late at night. After three days of no email response for my ticket, I called and after an hour of my life I want back, front line support cannot reproduce the loss. Final conclusion: "Your host is dropping packets". -- ~Randy

BCP38 and Red Hat
by Stephen Satchell 15 Dec '16

15 Dec '16

https://bugzilla.redhat.com/show_bug.cgi?id=1370963 Just a reminder that I have a feature request outstanding with Red Hat to add support for BCP38, as well as measures for certain protocol-based amplification reflection attacks. My intent for making the suggestion is to stiffen firewalld(8) in Red Hat Enterprise and clones, particularly when an RHEL-based box is used as an edge router or firewall box. I've looked at firewalld, and it would be easy to add *some* of BCP38 into it rather quickly...assuming that the developers step up to the plate. There are parts of BCP38 that won't be so easy to do, given the architecture of the package. In my spare time, by the way, I'm working on a BCP-compilant firewall generator for IPTABLES. Spare time? Well, that *is* a bit of a laugh...

DOS for hire issues
by ping murder 15 Dec '16

15 Dec '16

Hello, One of the hosting brands we recently acquired is overrun with DOS for hire providers and individuals. We kill them as they alert however I'm curious if there's a discussion group or location, contacts, etc we might be able to coordinate in about the actors behind these accounts (assuming this isn't the right place for that, however has a lot of the right people). If I'm out of my lane, forgive me. Thanks, pm

Yes. But don’t just put in coordinates... Put in other details and use a standard separator 😊 alan
