Wireshark Celebrates 25th Anniversary with a New Foundation

No doubt, countless engineers and hackers remember the first time they used newly-developed microscope to view cells for the first time ever: What was once just an inscrutable package had opened up to reveal a treasure trove of useful information. This year, the venerable Wireshark has turned 25, and its creators are taking a step back from this massively successful open source project, to let additional parties to help govern. This month, Sysdig, the current sponsor of Wireshark, launched a new foundation that will serve as the long-term custodian of the project. The

This Week in Computing: Malware Gone Wild

Malware is sneaky AF. It tries to hide itself and cover up its actions. It detects when it is being studied in a virtual sandbox, and so it sits still to evade detection. But when it senses a less secure environment — such as an unpatched Windows 7 box — it goes wild, as if Tudor Dumitras, in a recently posted talk from red pills, which helps malware detect when it is in a controlled environment, and change its behavior accordingly. As a result, many of the signatures used for commercial malware detection packages may not Continue reading

EU Analyst: The End of the Internet Is Near

The internet as we know it may no longer be a thing, warns a European Union-funded researcher. If it continues to fray, our favorite “network of networks” will just go back to being a bunch of networks again. And it will be the fault of us all. “The idea of an open and global internet is progressively deteriorating and the internet itself is changing,” writes Internet Fragmentation: Why It Matters for Europe” posted Tuesday by the

Cloud Foundry HTTP/2 Support Thwarted by GoLang Indifference

A Go Router reverse proxy removes headers that would let a CF application know it can send and receive HTTP/2 traffic. Such capability could be coded in, bypassing the Go language library entirely, but the project team doesn’t want to take on the responsibility for supporting such a potentially widely-used function. spoke about this challenge at this year’s virtual

How HAProxy Streamlines Kubernetes Ingress Control

In 2016, when the digital media arm of the in increasingly large numbers. “I remember the fear that the huge event we were experiencing could bring our platform down,” said recalled at HAProxy 2019. They kept watching the Grafana dashboard, searching for potential anomalies. In the end, however, nothing bad happened. “We ended up drinking beers and eating pizzas,” he said. But Gallissot didn’t want to go through such a stressful experience again, and so started an initiative to move M6 to the cloud. Like many organizations dealing with surges of traffic, M6 decided on Kubernetes as the platform for a multicloud architecture, to ease the process of easily scaling up and down traffic. And one of the most crucial parts of the Kubernetes setup is routing the incoming traffic to the appropriate services. Kubernetes itself offers an option to capture the

The New Stack Context: Stress, Resilience and the Network Effects of COVID-19

Welcome to The New Stack Context, a podcast where we discuss the latest news and perspectives in the world of cloud native computing. For this week’s episode, we spoke with The New Stack correspondent Jennifer Riggins about all of the reporting she and others on the TNS team have been doing recently on the effects that the COVID-19 global pandemic is having on the tech industry. TNS editorial and marketing director Libby Clark hosted this episode, alongside founder and TNS publisher Alex Williams and TNS managing editor Joab Jackson. Subscribe: | Stitcher | Overcast | TuneIn For this episode, we wanted to look at and not only discuss the changing patterns in network traffic that the global COVID-19 pandemic has wrought, due to factors such as people staying at home and working from home, and the sudden acceleration of e-learning. As Riggins writes in a recent post: For a lot of tech and infrastructure teams, they not only are going through the stress of the collective trauma we’re sharing in, but they are struggling to keep up with ever-scaling, extreme strains on their systems. Simply put, Continue reading

Dragonfly Brings Peer-to-Peer Image Sharing to Kubernetes

Dragonfly, a peer-to-peer image and file-sharing technology developed by Cloud Native Computing Foundation. The software provides a way to quickly distribute images across large cloud native deployments, eliminating the dependency on a single registry to distribute all the copies of an image. “Dragonfly is one of the backbone technologies for container platforms within Alibaba’s ecosystem, supporting billions of application deliveries each year, and in use by many enterprise customers around the world,” said Dragonfly in 2015, originally to ease file distribution. By 2017, when it was adopted to share containers within Kubernetes environments, it was being used by the Chinese cloud service to share 3.4PB each month. It was originally accepted into the OCI (Open Container Initiative). It can work with CNCF’s Prometheus and display them on a Helm can be used to install Dragonfly within a Kubernetes cluster. Project maintainers come from Alibaba, ByteDance, eBay, and Meitu. Overall it has 67 contributors from 21 organizations. It has been downloaded over 100,000 times from Docker Hub and has massed 6,000 GitHub stars. Learn more about Dragonfly, visit liggraphy from 

Istio 1.5 Brings a Binary Installer, WASM-Based Extensibility for Envoy

The newest version of the open source version 1.5, comes with a fresh installer to simplify the deployment process, along with a new extension model, based on WebAssembly (WASM), to help proxy servers better filter traffic. The development team behind Istio mark the Envoy‘s, the data plane most frequently used with Istio. “WASM will give developers the ability to safely distribute and execute code in the Envoy proxy — to integrate with telemetry systems, policy systems, control routing and even transform the body of a message,” a web page Linkerd and HashiCorp’s istioctl configuration tool. Security has been enhanced through the support of Kyle Glenn on 

Beyond Kube-Proxy: Project Calico Harnesses eBPF for a Faster Data Plane

Thanks to the power of the newly-introduced Calico network management software with a new data plane mode, one that can speed pod-to-pod data communication and eliminate the dependency on Kubernetes’ kube-proxy for traffic management. Tigera had started releasing work with eBPF almost a year ago, but this is the first release of Calico that fully harnesses the power of the new Linux kernel technology, Tigera co-founder and chief technology officer, said. “We wanted to derive what we were doing from fundamentals, to be confident we were building the right thing for users,” said scale Continue reading

HashiCorp’s Consul Brings Namespace Management to the Service Mesh

Consul services networking platform with the capability to manage service namespaces at an organization-wide level. Released Tuesday, Consul 1.7 also comes with additional plugins to support a number of application monitoring and management tools, including AppDynamics, Datadog and the NGINX proxy. HashiCorp presents Consul as a network automation tool for enterprises to connect and secure application services across multiple clouds and on-prem environments, putting all the services on a single communication plane with a shared registry. The thinking behind Consul is that “you need a namespace service registry for the new, dynamic environment,” noted on the HashiCorp blog. HashiCorp is a sponsor of The New Stack. Feature image

It Takes a Community: Kubernetes’ Long Road to Dual IPv4/IPv6 Support

Portworx sponsored The New Stack’s coverage of KubeCon+CloudNativeCon North America 2019. While you may thinking of Kubernetes as the future of computing, but it was, until recently, still stuck in the past in one way, namely that it was built on IPv4, the widely-used, though a soon-to-be-legacy version of the Internet Protocol upon which the internet was built. The Internet Engineering Task Force has been long urging the internet service providers to move to IPv6, now that the world has exhausted the supply of 32-bit IPv4 addresses. With its 128-bit address space, IPv6 will offer an inexhaustibly supply of internet addresses. “We ignored it,” admitted KubeCon + CloudNativeCon North America 2019 conference he gave with
