FreeBSD Jails is an awesome tool similar to Docker but much older which allows administrators and developers alike to have several securely contained userland environments sharing one kernel. Does it sound familiar? This is operating-system-level virtualization and it’s different than what you find on KVM or Xen camps. For more detailed information I’ve published some […]
Abandon Linux. How to export and import FreeBSD Jails ‘a la Docker’
Who am I?
My name is Albert Valbuena. I am a retired ski instructor and after a period of five years in the international department of a logistics company I recently moved in to the IT industry. It hasn’t been overnight and it is still work in progress. A few years ago I started a website called www.skireviewer.com. […]
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 […]

The root account
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 […]
How to mirror disks on FreeBSD’s ZFS
This article is not going to be a long, detailed, specialized how to. I just wanted to share the ease and the fantastic quality of ZFS for a dead simple need I had. A spare box with a spare disk doing nothing could be repurposed as a file share box at home. Mirroring the two […]
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.
