Security Auditing Tools For Ubuntu

Malware, where aren’t thou found? Well, even our wonderful Ubuntu can be infected. So what can we do about it? Hope and pray we keep our system safe and better yet, audit our systems regularly for malwares and rootkits. There are 4 system auditors for Ubuntu that we will review - lynis, rkhunter, chkrootkit, and clamav. [...] Oddly enough, there aren’t many tools to scan for malware out there for Linux. Why? I’m not sure. However, these 4 tools are more than enough to detect malwares, rootkits, and viruses. Also: Windows Finger command abused by phishing to download malware

• Set up a minimal server on a Raspberry Pi | Opensource.com

  Recently, the microSD (secure digital) card in my Raspberry Pi stopped working. It had been in constant use as a server for almost two years, and this provided a good opportunity to start fresh and correct a few problems. After its initial installation, it began experiencing disk problems and the official Raspberry Pi operating system (OS) received a significant update (and was renamed from Raspbian to Raspberry Pi OS). So I acquired a new microSD card and preceded to rebuild. Although this Raspberry Pi 3 Model B isn't the latest hardware, it is still adequate for running a minimal server for various services. I think my original installation used the full operating system image that includes the graphical user interface and a lot of other software packages unnecessary for my needs. This step-by-step guide shows how I set up my Raspberry Pi with the most minimal configuration to conserve precious system resources.

Chafa 1.6.0: Wider

Here’s another one from the terminal graphics extravaganza dept: Chafa 1.6.0 brings fullwidth character support, so in addition to the usual block elements and ASCII art, you now get some mean CJK art too. Or grab as many fonts as you can and combine all of the Unicode into one big glorious mess. Chafa can efficiently distinguish between thousands of symbols, so it also runs fast enough for animations — up to a point. Since some users want this in environments where it’s not practical to build from source or even to have nice things like GLib, I’ve started adding statically linked builds. These are pretty bare-bones (fewer image loaders, no man page), so look to your steadfast distribution first. Speaking of distributions, a big thank you to the packagers. Special thanks go to Florian Viehweger for getting in touch re. adding it to OpenBSD ports, and Mo Zhou (Debian), Michael Vetter (openSUSE), Herby Gillot (MacPorts), @chenrui and Carlo Cabrera (Homebrew) for getting 1.6 out there before I could even finish this post.
