How to use Fail2ban with WordPress

September 24, 2018 By Albert Valbuena

In a previous article we did an install of Fail2ban on a FreeBSD server. This tool can help us to protect our WordPress install, independatly from if we are using the FAMP stack or the LAMP stack. As I mentioned on that article Fail2ban is a complementary tool to our firewall. It works by scanning […]

How to install Docker on Ubuntu 18.04

February 25, 2019 By Albert Valbuena

Operating System level virtualization is hitting hard now, as much as VM’s did just a few years ago. Docker is the popular framework for this matter, the new kid on the block so to speak. This is the hot spot now and if anyone wants to appear knowledgeable about system administration knowing this technology is […]

How to mitigate Spectre and Meltdown on an HP Proliant server with Ubuntu

September 1, 2018 By Albert Valbuena

As recently announced in a previous article I wanted to write a couple of guides on how to mitigate Spectre and Meltdown vulnerabilities in GNU/Linux and UNIX environments. It is always a good and I hope a standard practice to have your systems patched and if they aren’t for whatever the reason (that legacy thing […]

How to configure the IPFW firewall on FreeBSD

July 22, 2019 By Albert Valbuena

Among the three possible firewalls on FreeBSD (choice is always nice) IPFW is the in-house built one. There is a default, easy way, configuration path but if one needs to build a box to act as a dedicated network appliance with packet filtering capacity fine tunning the IPFW firewall configuration is more than desirable. Before […]

How to analyze suspicious email

May 20, 2020 By Albert Valbuena

Millions of emails are sent and received every day. Most of them are just junk. And many among those are potentially harmful. Phishing still is one of the most effective ways for malicious actors to penetrate into well secured networks. The weakest link, too often, is the human factor. Training can help mitigate this 24×7 […]

How to upgrade MariaDB on FreeBSD

March 30, 2020 By Albert Valbuena

As we all know a best practice recommendation that has been made forever, and forever many are just skipping, is running up to date software and it is one of the core fundamentals of IT. If you happen to use MariaDB on FreeBSD, the official guide on their website may not be that all helpful […]

How to mitigate/solve the MDS vulnerabilities of Intel processors in FreeBSD

May 18, 2019 By Albert Valbuena

It had to happen again. Anyone betting on new hardware vulnerabilities on Intel processors would have won. This time these are called the MDS vulnerabilities, which stands for Microarchitectural Data Sampling. The trouble is the ones who would have really made big money would have been those stating the new CPUs were on the same […]

Contact

April 19, 2017 By Albert Valbuena

I am a busy guy. Answering comments takes precious time from my daily life so don’t get mad if I don’t reply you back quickly or if I just don’t do. Plus, think twice before posting. If you really have something interesting to say, just go ahead. If that is something you really think I’d […]

FreeBSD particularities

April 23, 2017 By Albert Valbuena

As some others unix-like operating systems FreeBSD has some particularities aside to the UNIX heritage, licensing and the like. The init system is the way a system starts up and the BSD has always been different. If you happen to be a UNIX admin I am sure you are aware of this and the folks […]

100 articles mark at Adminbyaccident.com

May 23, 2020 By Albert Valbuena

This is the 100th post here at Adminbyaccident. Little I knew when I starting posting that I would reach the ‘impossible’ mark of the 100 articles. Sure, some of them are not very interesting, nor instructive. Three years ago I wasn’t the same and I hope in three years time I’m still here and kicking. […]
