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

Over the past few weeks, I worked with two different configuration tools: Salt and Ansible. I started working with Salt. I quickly created a setup for a Salt server and for a Salt minion. The modules I saw looked great. However, I had consistently had trouble converting from the documentation to a practical usage. The

Tonight I asked a question in the OpenVPN IRC channel on FreeNode. me: I’m getting ready to set up a new server, running an OpenVPN client. It will be running several virtual machines (FreeBSD Jails). Each VM will have both a public IP address and a non-routable IP address. I’m hoping to access all those

I have an exciting project ahead of me. I will soon be configuring a new server. It will be ZFSROOT running a pair of mirrored 500GB disks. I plan to use a configuration tool for management of this server. The final choice of tools is yet to be decided. The services provided by this server

Sometimes you want to do things alone. Or rather, without intervention. Unattended. Bootstrapping the pkgng package management tool is one of those things. From the pkgng documentation, “FreeBSD 9.1 and later includes a bootstrap utility which can be used to download and install pkgng, along with its manual pages”. Let me show you how that
