In the previous video in this series, I described how path discovery works in source routing and virtual circuit environments. I couldn’t squeeze the discussion of hop-by-hop forwarding into the same video (it would make the video way too long); you’ll find it in the next video in the same section.
Curiefense is a new, open source Web application firewall designed for cloud-native environments. Currently a "sandbox" project in the Cloud Native Computing Foundation, Curiefense is now generally available.

Combining, or stitching together, open source projects to build something unique for your network is becoming more common. What does this look like in the real world? What are some of the positive and negative aspects of building things this way? How do open source projects interact with the commercial world? Daniel Teycheney joins Tom Ammon, Jett Tantsura, and Russ White to discuss open source software in networking, particularly around network monitoring and management.
Next week, on Thursday March 11th, 2021 (8am PST/5pm CET) we’ll be hosting our next quarterly Docker Community All-Hands. This free virtual event, open to everyone, is a unique opportunity for Docker staff and the broader Docker community to come together for company and product updates, live demos, community presentations and a live Q&A.
As luck would have it, this All-Hands will coincide almost to the day with Docker’s 8th birthday (yay!). To mark the occasion, we’re going to make this event extra special by introducing :
We’re also really excited about the new video platform we’ll be using that makes it much easier for attendees to engage/connect/share with each other.

We have been working with conntrack, the connection tracking layer in the Linux kernel, for years. And yet, despite the collected know-how, questions about its inner workings occasionally come up. When they do, it is hard to resist the temptation to go digging for answers.
One such question popped up while writing the previous blog post on conntrack:
“Why are there no entries in the conntrack table for SYN packets dropped by the firewall?”
Ready for a deep dive into the network stack? Let’s find out.
We already know from last time that conntrack is in charge of tracking incoming and outgoing network traffic. By running conntrack -L we can inspect existing network flows, or as conntrack calls them, connections.
So if we spin up a toy VM, connect to it over SSH, and inspect the contents of the conntrack table, we will see…
$ vagrant init fedora/33-cloud-base
$ vagrant up
…
$ vagrant ssh

[vagrant@ct-vm ~]$ sudo conntrack -L
conntrack v1.4.5 (conntrack-tools): 0 flow entries have been shown.
… nothing!
Even though the conntrack kernel Continue reading
A few months ago I described how you could use JSON Schema to validate your automation data models, host/group variable files, or even Ansible inventory file.
I had to use a weird toolchain to get it done – either ansible-inventory to build a complete data model from various inventory sources, or yq to convert YAML to JSON… and just for the giggles jsonschema CLI command requires the JSON input to reside in a file, so you have to use a temporary file to get the job done.

Phishing attacks have become more prominent and prevalent in recent years. In particular, our research into the cyber threat landscape over the last few months has shown a dramatic increase in the volume of phishing campaigns observed by our customers.
The most basic way to detect phishing is by using blacklists of phishing URLs. However, our research showed that, in many cases, the lifetime of phishing URLs is less than 24 hours, which renders the blacklist approach largely ineffective.
At VMware, we use multiple approaches to detect phishing attacks. The one we’ve found to be the most promising uses visual representation of the website to recognize phishing. In this blog post, we’ll discuss how this approach works in greater detail. If you need an overview of the more general idea behind phishing detection using image similarity, visit our previous blog post.
As one part of VMware’s phishing detection, we store information about the visual representation of every analyzed URL: that is, we calculate perceptual hashes of the screenshots Continue reading

Engineers are skeptical of vendor marketing, which is typically heavy on buzzwords and light on actual information. But technical marketing tries to change that dynamic by creating collateral to help engineers and practitioners understand a product. We get into this world with guest Martez Reed, Director of Technical Marketing at Morpheus Data.
