Donation Time 2020
This 2020 has been a difficult year for everyone. Because of this difficulty and the opportunities I had the chance to take, I’ve been able to contribute back to the open source community, not just with content here in Adminbyaccident.com, advocacy for a few tools such as my favorite OS (FreeBSD) and the usual mouthful […]
100 articles mark at Adminbyaccident.com
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.

How to detect a WAF – Web Application Firewall
From a penetration testing perspective to identify if a Web Application Firewall (WAF) is in place is essential. The next question is, does an administrator need to know this? My view is, anyone who is in charge of any system that has implemented some sort of WAF needs to verify this tool is working, at […]
How to install Apache in FreeBSD with pkgng
The Apache Web Server is one of the most widely deployed web servers around the world. There are new and powerful alternatives you may have heard of, such as NGINX which seems to be the coolest thing around lately. There are meaningful differences between the two.

FreeBSD particularities
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 […]
How to configure the PF firewall on FreeBSD
There are three firewall options on FreeBSD. The in-house built IPFW, the ‘old’ IPF (known as IP Filter) and PF ported from OpenBSD. PF is a very popular piece of software which was originally sparked from an issue on the IPF license that prevented making changes publicly available, which the OpenBSD did all the time. […]
