Hedge 126: George Michaelson on ISDN
ISDN, while an old technology, is still around in many parts of the world. When will it go away? George Michaelson joins Tom Ammon and Russ White to discuss the end of ISDN. The conversation then veers into old networking technologies, and the importance of ISDN in setting the terms and ideas we use today—ISDN is one of the key technologies around which network engineers built their mental maps of how to build and maintain networks.

The Key to Networking is First Getting a Good Night’s Sleep
Anyone who’s ever gone to a networking event knows that they can be exhausting. You’re constantly meeting new people, exchanging business cards, and trying to make a good impression. It’s no wonder that so many people end up burning out quickly.
The key to networking effectively is actually quite simple: getting a good night’s sleep beforehand.
How much sleep do you need to be at your best for networking events?
Most people need around eight hours of sleep per night to function at their best. However, if you know you have an upcoming networking event, it’s important to get even more sleep than usual. Try to get at least nine or ten hours of sleep the night before. This will help ensure that you’re well-rested and won’t be as likely to feel exhausted during the event.
How can you make sure you get enough sleep?
There are a few different things you can do to make sure you get enough sleep. First, avoid caffeine in the evening. Caffeine can stay in your system for up to eight hours, so it’s best to avoid it after lunchtime.
Second, establish a bedtime routine and stick to it as much as possible. Continue reading
Day Two Cloud 142: OpenZiti Serves Up Zero Trust For Applications (Sponsored)
Today's Day Two Cloud episode bites into OpenZiti, an open-source project that brings zero trust principles to networks and applications. OpenZiti builds an overlay network to enforce zero trust. It has several moving parts including edge routers, a controller, and SDKs. OpenZiti was created by NetFoundry, our sponsor for this episode. Guest Clint Dovholuk takes us through the nitty-gritty of how it works.Ransomware Attacks: You Can’t Protect What You Can’t See
To combat the rising tide of ransomware attacks, businesses are focusing on their IT inventory for the information they need to properly defend themselves.Red Hat Insights for Ansible Automation Platform New Report : Modules
Red Hat Insights is a suite of cloud services available on the Red Hat Hybrid Cloud Console, powered by an expert system that is built upon years of data collected from across Red Hat’s worldwide customer base. For Red Hat Ansible Automation Platform customers, it provides predictive analytical reporting of your Ansible automation.
This blog breaks down the new reports that analyze module usage within the Ansible Automation Platform.
In summary, module usage is really important because modules can contain security vulnerabilities and require updates to support new integrations of hardware or software. It is paramount to know which modules you are using in your automation.
Let's look at each report and what each of them can deliver for you.
Reports
Most used modules
Description: The number of job template and task runs, grouped by Ansible module usage.
Use Case: You can use this report to discover which modules are being used the most across your automation, helping you to check things like organization-wide adoption of purpose-built modules over potentially less performant, catch-all solutions.
Example:
This chart shows how the file and gather_facts modules are the most used, but also shows that over the past 6 Continue reading
Cloudflare partners with Kentik to enhance on-demand DDoS protection
We are excited to announce that as of today, network security teams can procure and use Magic Transit, Cloudflare’s industry-leading DDoS mitigation solution, and Kentik’s network observability as an integrated solution. We are excited to help our customers not just with technical simplicity, but business process simplicity as well.
Why monitoring and mitigation?
Distributed Denial of Service (DDoS) attacks are highly disruptive to businesses everywhere. According to the Cloudflare DDoS Attack Trends report, in the first half of 2021 the world witnessed massive ransomware and ransom DDoS attack campaigns that interrupted critical infrastructure, including oil pipelines, healthcare, and financial services. In the second half, we saw a growing swarm of attacks, including one of the most powerful botnets deployed (Meris), with record-breaking network-layer attacks observed on the Cloudflare network.
Along with an increase in severity, there is a proliferation of automated toolkits that make it simple and cheap for anyone to launch these attacks. Detecting and stopping these attacks manually is not effective, and network security engineers are increasingly turning to automated tools to help ensure network and application availability.
DDoS protection has evolved over the years from appliances to hybrid models to fully Internet-native solutions, like Continue reading
