How to install Redis for WordPress on FreeBSD

The root account

April 23, 2017 By Albert Valbuena

Users. What the hell you mean by “root”? Are you a Windows user? I bet you have the user account badly configured. By default Windows is installed under the Administrator account. And nobody bothers to change this and add a second account. That second account should be an underprivileged one. If you own the computer […]

FreeBSD Jails

January 8, 2018 By Albert Valbuena

The FreeBSD jails is a virtualization technology you may have skipped for too long. It is an operating system level virtualization and is one of the differential characteristics of FreeBSD from Linux. Solaris took it to the main corporate use with Zones and as it couldn’t be any other way the Illumos folks also play […]

How to format an USB drive on FreeBSD

June 22, 2019 By Albert Valbuena

File system support on FreeBSD falls onto UFS (UNIX File System) or originally named the FFS (Fast File System and on ZFS (Zetabyte File System). If you are using your box as a desktop-workstation you will use USB drives to share files with other systems, to carry things on your pocket or safe the day […]

Exploiting CVE-2019-0708 Remote Desktop Protocol on Windows

April 22, 2020 By Albert Valbuena

The CVE-2019-0708 is the number assigned to a very dangerous vulnerability found in the RDP protocol in Windows sytems. This is also known as the ‘Blue Keep’ vulnerability.

How to compile cloudflared in FreeBSD 13/14

October 21, 2024 By Albert Valbuena

I happen to self-host my websites using Cloudflare’s services (article 1, article 2). Since the FreeBSD port seems to be delaying its releases and Cloudflare’s policy on maintaining versions only considers 1 year old code, in an act of prevention I have learnt, and I am publishing, how to compile cloudflared in FreeBSD. Note: At […]

How to patch OpenSSH in FreeBSD 12.2

January 16, 2021 By Albert Valbuena

The default version of OpenSSH in FreeBSD 12.2 today, and it’s been this for quite some time, is not the most recent published by the OpenBSD guys, which by the way are the ones developing OpenSSH. Not only is not the latest but it has a few vulnerabilities affecting it, medium risk ones but nevertheless […]

LAMP stack stands for a software stack composed by Linux, Apache, MySQL and PHP (or Perl). It is used for many purposes and its common ground for system administrators.

How to load and unload kernel modules in Linux

May 15, 2023 By Albert Valbuena

Kernel modules permit enabling hardware features on a given system. For example, if we need to read from a particular filesystem from a hard drive, we need to load a particular kernel module. Or use a specific network card, a sound card or sound device, a video display, etc. This is mostly done automatically in […]

How to patch Spectre and Meltdown the ROM way

September 1, 2018 By Albert Valbuena

In a previous article I briefly, sort of, talked about the Spectre and Meltdown vulnerabilities. I have also written two guides to patch them from the OS side using a UNIX flavour from the BSD camp and a GNU/Linux distribution. Both actions resulted successful but there is a third way to patch this vulnerabilities. Regular […]

Abandon Linux. Jails for developers.

April 29, 2019 By Albert Valbuena

Reading the title you might think I want to put developers in Jail and although some may be good candidates this is in the far opposite of my intention. I am talking about FreeBSD Jails. For the unfamiliar with the concept those Jails are userland secure contained environments that share a common kernel. Purists and […]
