Join Us And Paul Vixie On Tuesday To Discuss BIND, Root Servers, And DNS Security
CloudFlare and Gandi have been hosting a speaker series on DNS, previously bringing in the founder of DNS Paul Mockapetris and Dan Kaminsky, who uncovered one of the most critical vulnerabilities in DNS.
Our third and final talk is coming up on June 21st at 6PM PST at the Gandi office in San Francisco (live stream link will be posted on the Meetup page) and you won’t want to miss it, because our speaker is none other than Paul Vixie.
Paul wrote most of BIND Version 8 and hired the team who wrote BIND Version 9, the most widely used DNS software on the Internet. He founded ISC, home of BIND and F-root and later operated C-root.
We'll talk about alternative DNS root servers, email security and spam (Paul founded the first ever anti-spam company), and what needs to be done about DNS and security (Paul added most of BIND’s current security systems).
So come grab a beer and let's geek out about DNS one more time.
Worth Reading: The history of the Intel CPU
The first microprocessor sold by Intel was the four-bit 4004 in 1971. It was designed to work in conjunction with three other microchips, the 4001 ROM, 4002 RAM and the 4003 Shift Register. Whereas the 4004 itself performed calculations, those other components were critical to making the processor function. -Tom’s Hardware

Monitoring VMware NSX SpoofGuard with REST API and Perl
In some prior blogs, we demonstrated leveraging NSX REST API with Python. See prior blogs, Automating Security Group and Policy Creation with NSX REST API and Automating VMware NSX Security Rules Creation using Splunk and Some Code. In this blog, we demonstrate how NSX REST API can be used with the popular Perl programming language.
One of Perl’s key strengths is the vast amount of Perl modules/libraries available via the Comprehensive Perl Archive Network (CPAN). There is also a CPAN module included with Perl which is used to automatically download and install additional Perl modules from the CPAN repository. The example Perl code in this post demonstrates a simple program that uses a Perl REST client module/library with NSX REST API to retrieve NSX SpoofGuard information. Continue reading
