Aruba flexes some IoT muscle

Debugging war story: the mystery of NXDOMAIN

The following blog post describes a debugging adventure on Cloudflare's Mesos-based cluster. This internal cluster is primarily used to process log file information so that Cloudflare customers have analytics, and for our systems that detect and respond to attacks.

The problem encountered didn't have any effect on our customers, but did have engineers scratching their heads...

The Problem

At some point in one of our cluster we started seeing errors like this (an NXDOMAIN for an existing domain on our internal DNS):

lookup some.existing.internal.host on 10.36.0.9:53: no such host

This seemed very weird, since the domain did indeed exist. It was one of our internal domains! Engineers had mentioned that they'd seen this behaviour, so we decided to investigate deeper. Queries triggering this error were varied and ranged from dynamic SRV records managed by mesos-dns to external domains looked up from inside the cluster.

Our first naive attempt was to run the following in a loop:

while true; do dig some.existing.internal.host > /tmp/dig.txt || break; done

Running this for a while on one server did not reproduce the problem: all the lookups were successful. Then we took our service Continue reading

Trump’s plan for protecting IT jobs raises hopes, fears

President-elect Donald Trump is showing a willingness to wage an economic battle with firms that move jobs offshore. He's threatening tariffs and promising H-1B visa reform, but may be offering carrots as well, namely tax incentives.These actions may be raising hopes among some IT employees who have lost jobs, or are losing them, that the incoming Trump administration is serious about keeping IT jobs in the U.S. But Trump's proposals -- particularly the tariff -- are also raising much uncertainty.Trump, in a series of tweets this weekend, reaffirmed plans to impose a 35% import tariff on "cars, A.C. units etc," on goods made by offshore U.S. firms but sold in the U.S.To read this article in full or to leave a comment, please click here

EU approves LinkedIn deal after Microsoft makes concessions

The European Union's regulators on Tuersday approved Microsoft's acquisition of social network LinkedIn on the condition that the U.S. company abide by several minor concessions it made to secure the deal.The conditions were reminiscent of those forced on Microsoft in past antitrust actions, including the settlement between the firm and the U.S. Justice Department early in the century, and a later judgment against Microsoft in the European Union (EU).Microsoft promised it would not require PC makers to install a LinkedIn app or Windows 10 tile on machines sold in the European Economic Area (EEA), the region consisting of EU member states as well as Iceland, Liechtenstein and Norway. Users will be able to remove any LinkedIn app or tile in Windows, Microsoft said, and pledged that it would not use Windows to nag customers to install a LinkedIn app.To read this article in full or to leave a comment, please click here

While the San Francisco 49ers are leading the NFL in defense, the New Orleans Saints currently hold the number one slot for total offense. In the overall league rankings, though, neither of those two teams rank in the top 10. What's the takeaway? Winning isn't strictly about strong offense or impenetrable defense. NFL league leaders advance to the top because they know how to balance the two; they know how to play the game.To address the growing number of attacks on the US government and private sector systems, President-elect Donald Trump's cybersecurity plan aims to, "Develop the offensive cyber capabilities we need to deter attacks by both state and non-state actors and, if necessary, to respond appropriately."To read this article in full or to leave a comment, please click here

Q&A: Building a Layer-2 Data Center Fabric in 2016

One of my readers designing a new data center fabric that has to provide L2 transport across the data center sent me this observation:

While we don’t have plans to seek an open solution in our DC we are considering ACI or VXLAN with EVPN. Our systems integrator partner expressed a view that VXLAN is still very new. Would you share that view?
