netlab release 1.3 introduced support for VXLAN transport with static ingress replication. Time to check how easy it is to replace a VLAN trunk with VXLAN transport. We’ll use the lab topology from the VLAN trunking example, replace the VLAN trunk between S1 and S2 with an IP underlay network, and transport Ethernet frames across that network with VXLAN.

Hello my friend,
As mentioned in the previous blogpost, we continue looking into Kubernetes. In the previous blogpost we have built a simple cluster consisting of one control plane node, which is the one ruling the cluster, and two worker nodes, which are the ones hosting the customers’ workloads. Today we will add a few more nodes, both workers and control plane, to the cluster to convert it into a high available one.

We absolutely are. One of the important things we have figured out is that automation is for sure the cross-platform technology. Therefore, whatever area you are coming from or heading two (networking, system administration, or cloud engineering), knowledge of automation frameworks and components, such as Ansible, Bash, Python, YAML, JSON, REST API, GRPC/GNMI is very beneficial and, in fact, is almost mandatory these days.
And in our Network Automation Trainings we have put it together in Continue reading
Cloudflare launched on September 27, 2010. This week we'll celebrate our 12th birthday. As has become our tradition, we'll be announcing a series of products that we think of as our gifts back to the Internet. In previous years, these have included products and initiatives like Universal SSL, Cloudflare Workers, our Zero Markup Registrar, the Bandwidth Alliance, and R2 — our zero egress fee object store — which went GA last week.
We're really excited for what we'll be announcing this year and hope to surprise and delight all of you over the course of the week with the products and features we believe live up to our mission of helping build a better Internet.
While this will be our 12th Birthday Week of product announcements, for the last two years, as the cofounders of the company, we've also taken this time as an opportunity to write a letter publicly reflecting on the previous year and what's on our minds as we go into the year ahead.
Since our last birthday, it's been a tale of two halves of a very different year. At the end of 2021 and into the first two months Continue reading
Charity Majors published another masterpiece: The Hierarchy Is Bullshit (And Bad For Business).
I doubt that anyone who would need this particular bit of advice would read or follow it, but (as they say) hope springs eternal.

Encrypted traffic poses a problem for enterprise policy enforcement. On today's Heavy Networking, we explore the notion of zero knowledge middleboxes, which use a variety of techniques to allow firewalls or other middleboxes to enforce policy without the need for decryption. Our guest is Dr. Paul Grubbs, whose research into zero knowledge middleboxes prompted this episode.

Back in 2019, we worked on a chart for Cloudflare’s IPO S-1 document that showed major releases since Cloudflare was launched in 2010. Here’s that chart:
Of course, that chart doesn’t show everything we’ve shipped, but the curve demonstrates a truth about a growing company: we keep shipping more and more products and services. Some of those things start with a beta, sometimes open and sometimes private. But all of them become generally available after the beta period.
Back in, say, 2014, we only had a few major releases per year. But as the years have progressed and the company has grown we have constant updates, releases and changes. This year a confluence of products becoming generally available in September meant it made sense to wrap them all up into GA Week.
GA Week has now finished, and the team is working to put the finishing touches on Birthday Week (coming this Sunday!), but here’s a recap of everything that we launched this week.

The post EX4400 VC Ports Conversation first appeared on Fryguy's Blog.You go to a website or service, but before access is granted, there’s a visual challenge that forces you to select bikes, buses or traffic lights in a set of images. That can be an exasperating experience. Now, if you have iOS 16 on your iPhone, those days could be over and are just a one-time toggle enabled away.
CAPTCHA = "Completely Automated Public Turing test to tell Computers and Humans Apart"
In 2021 and 2022, we took direct steps to end the madness that wastes humanity about 500 years per day called CAPTCHAs, that have been making sure you’re human and not a bot. In August 2022, we announced Private Access Tokens. With that, we’re able to eliminate CAPTCHAs on iPhones, iPads and Macs (and more to come) with open privacy-preserving standards.
On September 12, iOS 16 became generally available (iPadOS 16 and macOS 13 should arrive in October) and on the settings of your device there’s a toggle that can enable the Private Access Token (PAT) technology that will eliminate the need for those CAPTCHAs, and automatically validate that you are a real human visiting a site. If you already have iOS 16, here’s what you should Continue reading
