Making Network Device Management Safe
Tony Fortunato explains how companies can safely use Telnet and SNMP v1/v2.

This excerpt from Joakim Verona’s "Practical DevOps" covers code control, including repositories like GitHub.
Buffers Sometimes Beat Bandwidth For Networks
Just like every kind of compute job cannot be handled by a single type of microprocessor, the diversity of networking tasks in the datacenters of the world require a variety of different switch and router ASICs to best manage those tasks.
As the volume leader in the switching arena, Broadcom comes under intense competitive pressure and has to keep on its toes to provide enough variety in its switch chips to keep its rivals at bay. One way that Broadcom does this is by having two distinct switch ASIC lines.
The StrataXGS line of chips have the famous and ubiquitous …

You Don’t Need Programming Skills to Build Network Automation Solutions
I got several questions along the lines of “Do I need programming skills to attend the Building Network Automation Solutions course?”
Short answer: No.

In November I wrote about some simple tests that I had undertaken on the DNS Root nameservers. The tests looked at the way the various servers responded when they presented a UDP DNS response that was larger than 1,280 octets. I awarded each of the name servers up to five stars depending on how that managed to serve such large responses in IPv4 and IPv6. I'd like to return to this topic by looking at one further aspect of DNS server behaviour, namely the way in which servers handle large UDP responses over IPv6.Configuring the Future for FPGAs in Genomics
With the announcement of FPGA instances hitting the Amazon cloud and similar such news expected from FPGA experts Microsoft via Azure, among others, the lens was centered back on reconfigurable hardware and the path ahead. This has certainly been a year-plus of refocusing for the two main makers of such hardware, Altera and Xilinx, with the former being acquired by Intel and the latter picking up a range of new users, including AWS.
In addition to exploring what having a high-end Xilinx FPGA available in the cloud means for adoption, we talked to a couple of companies that have carved …

Datanauts 063: Unikernels Vs. Containers
Unikernels are emerging as an alternative to containers. Find out why with the Datanauts and guest Adam Wick. The post Datanauts 063: Unikernels Vs. Containers appeared first on Packet Pushers.Orin’s flawed argument on IP address privacy
In the PlayPen cases, judges have ruled that if you use the Tor network, then you don't have a reasonable expectation of privacy. It's a silly demonstration of how the law is out of sync with reality, since the entire point of using Tor is privacy.
Law prof Orin Kerr has a post discussing it. His conclusion is correct, that when the FBI exploits 0day and runs malware on your computer, then it's a search under the Fourth Amendment, requiring a warrant upon probable cause.
However, his reasoning is partly flawed. The title of his piece, "Remotely accessing an IP address inside a target computer is a search", is factually wrong. The IP address in question is not inside a target computer. This may be meaningful.
First, let's discuss how the judge reasons that there's no expectation of privacy with Tor. This is a straightforward application if the Third Party Doctrine, that as soon as you give something to a third party, your privacy rights are lost. Since you give your IP address to Tor, you lose privacy rights over it. You don't have a reasonable expectation of privacy: yes, you have an expectation of privacy, Continue reading

Get all the Docker talks from Tech Field Day 12
As 2016 comes to a close, we are excited to have participated in a few of the Tech Field Day and inaugural Cloud Field Day events to share the Docker technology with the IT leaders and evangelists that Stephen Foskett and Tom Hollingsworth have cultivated into this fantastic group. The final event was Tech Field Day 12 hosting in Silicon Valley.
In case you missed the live stream, check out videos of the sessions here.
Session 1: Introduction to Docker and Docker Datacenter
Session 2: Securing the Software Supply Chain with Docker
Session 3: Docker for Windows Server and Windows Containers
Session 4: Docker for AWS and Azure
Session 5: Docker Networking Fabric
These are great overviews of the Docker technology applied to enterprise app pipelines, operations, and diverse operating systems and cloud environments. And most importantly, this was a great opportunity to meet some new people and get them excited about what we are excited about.
