by Antonio Querubin 07 Dec '14

07 Dec '14

Trying to gather information on a connectivity issue between TW Telecom and a specific government web server. If one of your upstream providers is TW Telecom, could you report back whether you have connectivity to https://safe.amrdec.army.mil. Thanks.

A case against vendor-locking optical modules
by Jérôme Nicolle 06 Dec '14

06 Dec '14

Hello, I'm having a discussion with Arista, trying to explain to them why I _can't_ buy any hardware unable to run with compatible optical modules. My points are : - I need specific modules, mostly *WDM and BiDi, some still unavailable in their product line - I run at least two other vendors on every locations and can't stack up every spare optics for each of them, neither could remote-hands safely re-program optics to match a specific vendor when needed. - I have an established relationship with a trusted optics supplier, providing support, warranty and re-coding hardware for their entire (impressive) lineup. And this supplier is still 2-5x times cheaper than any vendor-labeled optics even with NFR-like discounts. Based on these points, I discourage every customers of ever using locked-in equipments, and forbid them on my own network. Of course, Arista can't be pleased because their hardware never stepped chord in my customer's networks. But they seem to deliberatly miss my points every time the subject comes up. What are other arguments against vendor lock-in ? Is there any argument FOR such locks (please spare me the support issues, if you can't read specs and SNMP, you shouldn't even try networking) ? Did you ever experience a shift in a vendor's position regarding the use of compatible modules ? Thanks ! -- Jérôme Nicolle +33 6 19 31 27 14

10Gb iPerf kit?
by Daniel Rohan 06 Dec '14

06 Dec '14

We're looking for a semi-portable solution to validate 10Gb customer circuits and hitting walls surrounding PCI lanes and the amount of data laptops can push via their busses. We'd prefer to not have techs lugging around server equipment for these tests. Anyone out there testing 10gbE with iPerf? If so, what are you using? Thanks, Dan

determine relationship between the operators based on import and export statements in aut-num object?
by Martin T 05 Dec '14

05 Dec '14

Hi, bit weird question, but is it possible to determine relationship(Internet transit, settlement-free peering, etc) between the operators based on import and export statements in aut-num object? Often aut-num objects in RIR database contain the remarks which describe such relationships. However, for example here I have following import and export attributes from an aut-num object of an ISP: import: from AS65133 action pref=100; accept ANY import: from AS65798 accept AS65798 import: from AS65084 accept AS65084 import: from AS65485 action pref=100; accept ANY import: from AS65751 accept AS65751 import: from AS65059 action pref=100; accept ANY import: from AS65128 accept AS65128 export: to AS65133 announce AS-SET export: to AS65798 announce ANY export: to AS65084 announce ANY export: to AS65485 announce AS-SET export: to AS65751 announce ANY export: to AS650835 announce AS-SET export: to AS65128 announce ANY Am I correct that it is safe to say that probably AS65133, AS65485 and AS65059 are the uplink providers and AS65798, AS65084, AS65751 and AS65128 are the customers of this ISP? Last but not least, maybe there is altogether a more reliable way to understand the relationship between the operators than aut-num objects(often not updated) in RIR database? thanks, Martin

Anybody at Amazon AWS?
by Anne P. Mitchell, Esq. 04 Dec '14

04 Dec '14

Anybody have a contact at Amazon AWS? I sent in a spam complaint, and got back the below response - while I give them kudos for actually, you know, responding, I'm pretty sure that we can all agree that "sending the same canned message to email addresses scraped off websites" is the very definition of spam, yet somehow the EC2 abuse team seems to consider it a perfectly acceptable explanation - I'd sure love to discuss this with someone with a clue at Amazon AWS --- Our customer has responded to your abuse report and provided the following information "The below emails were sent individually to the recipient using a canned message. There is no automation or mass emailing at all. Our publisher representative personally visited each of the below websites, decided they were right for our service and emailed them individually. The emails are sent through gmail using a web interface to their API. Let me know if you require any additional information. Dwayne" If you are satisfied with the above information, there is no need to respond to this notice. If you are not satisfied, please respond with a clear, succinct reason for dissatisfaction and what results you desire from our customer. We will make every reasonable attempt to work with you and our customer to resolve this matter. Thank you, The EC2 Abuse team --- Anne Anne P. Mitchell, Esq.

Re: How to track DNS resolution sources
by Notify Me 04 Dec '14

04 Dec '14

Hi Nick and List Yes it's possible. The dud DNS response in some parts of the internet was the public IP address being used by their proxy server. I'm not sure what the proxy is, but it's a windows box. I was going to try to dig trace but by then the poisoning suddenly stopped happening. Any other ideas on how to deal with this ? What can I proactively do in case it happens again?
