FOSS Linux takes a look at ten possible risks when dual-booting operating systems.
TecAdmin published a tutorial about installing Python 3.10 on Ubuntu, Debian, and Linux Mint.
KernelCare lets you patch the Linux kernel without rebooting, and this article walks through how to set it up on both Debian‑based and RHEL‑based distributions while also showing a quick way to wipe its cache.
On Ubuntu or Debian you first download a signed installer script that adds an APT repository, then run the key command with your personal API key before enabling the kernelcare.service at boot so it automatically starts after each restart.
For CentOS and RHEL, the same shell script configures YUM, followed by registering the key with kernelcare-apikey and starting the service; once running you can stop it, delete everything in /var/cache/kernelcare to reclaim space, and restart so fresh patches are fetched again.
If connectivity fails or the daemon is unintentionally disabled after an upgrade, re‑enable it and check proxy settings, while a real‑world example showed that clearing the cache resolved a kernel module load failure after a power loss.
The post walks you through installing Darkstat on the most common Linux flavours—Debian/Ubuntu, CentOS/RHEL and Fedora/RHEL 9+—with straightforward apt‑y or dnf commands that pull a ready‑made binary from EPEL. It then shows how to tweak `/etc/darkstat.conf`, setting your interface, port, log size and exposing the web UI so you can reach it from outside localhost. Next the article explains what the dashboard displays: overall traffic counts, top talkers, protocol pie charts and a 24‑hour trend line, and it even shares an anecdote about a smart thermostat spiking data usage during firmware updates. Finally it covers practical housekeeping like log rotation, sanity checks when no packets show up, and urges you to investigate odd spikes as clues to hidden network activity.
This guide explains how to keep hard drives healthy by installing and configuring smartctl on both CentOS 8 / RHEL 8 and Ubuntu 20.04, showing the steps needed to pull in the required repositories, install the package, and verify the version. On CentOS systems it walks through enabling EPEL, using dnf to grab smartmontools, identifying disks with lsblk, running a quick SMART report, and then creating a small shell script that logs health status and optionally emails alerts while scheduling it with cron for daily execution. For Ubuntu users it mirrors the installation process with apt, demonstrates a simple single‑line health check, and then sets up a modern systemd service and timer pair that runs smartctl each day, letting you query the timer status whenever you need to see when checks occurred. The article closes by sharing a real‑world incident where an abrupt power loss caused a sudden spike in reallocated sectors, illustrating how daily monitoring could have saved data, and it encourages readers to stick scripts or timers in place to avoid surprise failures.

The guide explains why turning off directory browsing on web servers is essential for security and then walks the reader through simple steps for both Apache and Nginx. For Apache you can edit the main configuration or drop an .htaccess file containing “Options -Indexes” to remove the Indexes flag that otherwise generates a listing of every file in a folder without an index page. On Nginx the solution is even shorter: add “autoindex off;” inside the server block and then test and reload the service to apply the change. A quick checklist table summarizes the flags for each server, and the article ends with reassurance that disabling directory browsing is a trivial but powerful security measure.
The guide walks readers through setting up an SSH server inside a Docker container so they can log in like a regular Linux box, even when the container is running on a remote host. It explains that while docker exec can run commands, SSH provides a true login shell for debugging services that expect interactive input or need to be accessed from another machine, and it walks through choosing an image, installing OpenSSH, creating a non‑root user, exposing port 22 (often remapped to 2222), and ensuring sshd starts via a simple entrypoint script. After the container is up, users can simply SSH into it with the provided credentials, run commands, test connectivity, or reset passwords as needed, and when finished clean everything up by stopping and removing the container and any temporary image. Finally, the article acknowledges that for most command execution cases docker exec suffices, but having an SSH session is valuable when a full terminal experience across machines is required.

This guide walks readers through turning a new Elasticsearch cluster from an open‑to‑everyone service into a locked‑down system by enabling X‑Pack Security. It starts with simple prerequisites such as having 7.x or 8.x installed, enough RAM, and root access, then explains how to turn on the security module in `elasticsearch.yml` and set up TLS for both node‑to‑node and client traffic. Next, it covers generating a CA and server certificates with OpenSSL, creating keystore and truststore entries, restarting Elasticsearch, configuring Kibana’s connection string, and finally creating or resetting admin users via the Security API. The article finishes with practical troubleshooting hints and reminds readers that once these steps are completed the cluster is secure against anonymous access and unencrypted data exposure.
