Leveraging the Sys Admin Brain • System administrators are your front-line soldiers: the eyes, ears, and hands of the company

Tech News

DIY MIBs • Measured values and status information can be collected and retrieved, messages received, and configurations changed remotely by SNMP, but if you want to do this for your own hardware or software, you need your own Management Information Base module.

First Aid Kit • Ceph is powerful and efficient, but wrong settings or faulty hardware can cause the decentralized object store to stumble.

Knowledge • A number of techniques applied in PowerShell or other management tools can run Windows servers more effectively, harden them, and improve their performance.

Block by Block • Not every backup tool is useful for backing up entire data media. Rescuezilla makes perfect bit-level copies of mass media in a matter of minutes, so you can completely reconstruct the system if disaster strikes.

Ads Subtracted • We compare seven free blocking filters for advertisements and look at how they integrate into the network

Teamwork • We compare three popular packages that are designed to simplify teamwork: EGroupware, Group Office, and Kopano.

Package Delivery • Calico chooses an unusual approach for software-defined networking, relying on open standards like BGP. We look at the distinctions and advantages of Calico.

Port of Call • The Dockly terminal tool helps you troubleshoot and manage multiple Docker containers

Supertanker • VMware Tanzu comprises several tools and services that make it easy to build, run, and manage a Kubernetes environment from a single point of control

Night Vision • StatusBay lets you see exactly what is going on behind the scenes when you run a Kubernetes command.

Traffic Control • The nimble Envoy proxy server addresses modern container environments, but does it outperform its rival Istio, which has Envoy at its core?

Second Sight • Set up an Elastic Stack quickly and easily with Helm to visualize Kubernetes data.

Fly by Sight • Administer a small server farm, virtual machines, and the Docker alternative Podman with just a web browser.

Distress Signals • Most storage devices have SMART capability, but can it help you predict failure? We look at ways to take advantage of this built-in monitoring technology with the smartctl utility from the Linux smartmontools package.

Spick and Span • Release 2 of Percona Monitoring and Management for open source databases helps reign in inefficient queries and ensure you are making the best use of the available hardware.

Blast from the Past • We show you how to build a compact, single-task device – if you dare to crack open an old laptop.
