Having just shot myself in the foot by deleting docker and losing a container I had been working on, here is the command to restore data to netbox-docker’s Postgres database:
sudo docker exec -i netbox-docker_postgres_1 psql --username netbox netbox < /path/to/backup/file.sql
Phew…
One of the readers of the Considerations for Host-Based Firewalls blog post wrote this interesting comment:
Perhaps a paradigm shift is due for firewalls in general? I’m thinking quickly here but wondering if we perhaps just had a protocol by which a host could request upstream firewall(s) to open access inbound on their behalf dynamically, the hosts themselves would then automatically inform the security device what ports they need/want opened upstream.
Well, we have at least two protocols that could fit the bill: Universal Plug and Play and Port Control Protocol (RFC 6887).
In July we announced a new strategic partnership with Amazon to integrate the Docker experience you already know and love with Amazon Elastic Container Service (ECS) with AWS Fargate. Over the last couple of months we have worked with the community on the beta experience in Docker Desktop Edge. Today we are excited to bring this experience to our entire community in Docker Desktop stable, version 2.3.0.5.
You can watch Carmen Puccio (Amazon) and myself (Docker) and view the original demo in the recording of our latest webinar here.
What started off in the beta as a Docker plugin experience docker ecs has been pulled into Docker directly as a familiar docker compose flow. This is just the beginning, and we could use your input so head over to the Docker Roadmap and let us know what you want to see as part of this integration.
There is no better time to try it. Grab the latest Docker Desktop Stable. Then check out my example application which will walk you through everything you need to know to deploy a Python application locally in development and then again directly to Amazon ECS in minutes not Continue reading
Library access: The Kyrgyzstan Chapter of the Internet Society has started work on version 2.0 of its ilimBox project, an online educational platform for teachers and students. The ilimBox device, now powered by the Raspberry Pi 4, will include new educational videos, audio, and text resources. IlimBox is a digital library for schools and public libraries, containing Wikipedia in Kyrgyz, Russian, and English, the Khan Academy electronic library in English, and thousands of video lessons, audio, and electronic books. All these digital training materials can be used offline, with users not needing immediate access to the Internet, although the library also connects to services through WiFi. As of last November, about 100 schools in Kyrgyzstan had installed ilimBox.
Building a better network: The Ghana Chapter has a post on efforts to improve the wireless network at Ho Technical University, and the author credited training from the Internet Society on community networks in helping him sort out problems with the network there. The campus network “had a lot of issues such rogue DHCP servers and IP address conflicts,” the author noted.
Algorithmic privacy: The Commission for the Protection of Privacy in Canada has given a grant to the Quebec Chapter Continue reading
Communication Servers designed to support hundreds or thousands of users reached their peak capabilities just as dial-up service access began to recede in importance. In fact, many network engineers today have probably never managed a dial-up communications server, which were once used to connect everything from individual users to services like AOL and remote workers to entire sites (hence OSPF’s demand circuit capability). Kevin Herbert joins us to discuss the early work on communication servers, including some of the challenges of working with early networking hardware.
On today’s program, some kickoff analysis of the Nvidia/Arm deal; a look at geospatial AI and what it requires in terms of future hardware and frameworks; physics-informed AI and what it means for future simulations and use cases; the Summit supercomputer and the “right” architecture for large-scale, multidisciplinary COVID-19 research; the elements of a hyperconverged data platform; infrastructure as code; much more in today’s interview lineup. …
Next Platform TV for September 15, 2020 was written by Nicole Hemsoth at The Next Platform.
Application delivery velocity can be tripped up when security vulnerabilities are discovered after an app is deployed into production. Nothing is more detrimental to shipping new features to customers than having to go back and address vulnerabilities discovered in an app or image you already released. At Docker, we believe the best way to balance the needs for speed and security is to shift security left in the app delivery cycle as an integral part of the development process.
Integrating security checks into Docker Scan was the driver behind the partnership with Snyk, one of the leading app security scan providers in the industry. This partnership, announced in May of this year, creates a vision for a simple and streamlined approach for developers to build and deploy secure containers. And today, I’m excited to share that the latest Docker Desktop Edge release includes Snyk vulnerability scanning. This allows Docker users to trigger local Docker file and local image scans directly from the Docker Desktop CLI. With the combination of Docker Scan and Snyk, developers gain visibility into open source vulnerabilities that can have a negative impact on the security of container images. Now you can extend your Continue reading
For more than two decades, VMware has made its money sensing the direction that enterprise IT is going and getting there before they do with products to addressing their needs. …
VMware Bets On Enterprises Wanting Kubernetes And Virtualization Mashup was written by Jeffrey Burt at The Next Platform.
By Kevin Lees and Devyani Pisolkar, authors of the ‘Operationalizing VMware NSX’ guide
Virtualized networking and security may appear to be a standard feature of today’s modern data center, but it wasn’t so long ago — what, seven years? — that network virtualization was a new concept, largely introduced and propelled by VMware. How time flies. Today, across industries, network virtualization, in the form of VMware NSX, is the go-to choice for delivery of software-based network and security services. Nowadays we spend less time discussing the novelty of the architecture and more time talking about how to maximize the value of NSX by fully operationalizing the platform to make it a critical driver in your digital transformation.
VMware NSX delivers networking and security services entirely in software. That enables organizations to move myriad operational tasks into the software layer, but to leverage it fully requires a top-to-bottom rethink of network operation itself. Under NSX, the old paradigm of the network as a hardware silo is gone; instead, the virtualized NSX network is an integral component in the software-defined data center.
Which brings us to the key point: in order to fully realize Continue reading
If you already understand how Secondary DNS works, please feel free to skip this section. It does not provide any Cloudflare-specific information.
Secondary DNS has many use cases across the Internet; however, traditionally, it was used as a synchronized backup for when the primary DNS server was unable to respond to queries. A more modern approach involves focusing on redundancy across many different nameservers, which in many cases broadcast the same anycasted IP address.
Secondary DNS involves the unidirectional transfer of DNS zones from the primary to the Secondary DNS server(s). One primary can have any number of Secondary DNS servers that it must communicate with in order to keep track of any zone updates. A zone update is considered a change in the contents of a zone, which ultimately leads to a Start of Authority (SOA) serial number increase. The zone’s SOA serial is one of the key elements of Secondary DNS; it is how primary and secondary servers synchronize zones. Below is an example of what an SOA record might look like during a dig query.
