Script for listing the latest ZFS snapshot – starting place for Bacula backups
This post has it all: backups deduplication snapshots ZFS Bacula ezjail Backups are essential for proper sanity, or at least, a reasonable facsimile. I strongly believe that doing backups right is the only way to backup. Go big or go home. I’ve been converting all my servers to ZFS. I like ZFS for many reasons,

su: _secure_path: /nonexistent/.login_conf is not owned by uid 65534
This morning, on a FreeBSD 9.2-RELEASE #0 r255898 system, I saw this in /var/log/messages: There was nothing around that entry to clue me in. I suspected a cronjob, based upon the time of day. I searched with Google and found only questions. This next command confirms my cronjob suspicion: OK, it’s got to be a

How Designers Destroyed the World
I recently watched a great video about design decisions. It features Mike Monteiro speaking at Webstock 13. I particularly liked these quotes: 28:15 – And remember every single time that you, as a designer, make it easier and more pleasant for anyone to find and use information and tools that help people live their lives,

Updating your IPv6 tunnel after an IP address change
I don’t yet have IPv6 native at home. Perhaps Verizon FiOS will provide it soon. In the meantime, I make use of Hurricane Electric, which seems to be everyone’s go-to ISP for tunnels. This post isn’t about creating an IPv6 tunnel. It’s about making sure that tunnel is rebuilt after you have an IP address

FreeBSD jails on non-routable IP addresses
One of my goals with the server I’m setting up is putting non-public services into jails with non-routable IP addresses. Today, I’ve been working on getting PostgreSQL into a jail. The problem I have been grappling with is not putting PostgreSQL into a jail but routing. It took me a while to figure out where

Accessing FreeBSD Jails over OpenVPN
With this new server, I am taking a new approach. Each jail will have at least three IP addresses: The public IP4 address, used by internet facing services (e.g. http or https) The public IPv6 address, similar to the above A VPN address, used for system administration and private services (e.g. nrpe) In this article,

Bootstrapping a new FreeBSD jail host as an Ansible node
A few days I configured a new server to be an Ansible node. This will allow my Ansible configuration tool to configure and install software. Installing Ansible and getting it running is not covered by the post. All I show here is how I got a remote server ready to be configured by Ansible. The
