Multi-WAN DNS in pfSense

Update: I later figured out there are many other places pfSense restarts Unbound, so this is simply not worth the effort.

ZFS convert stripe to striped-mirror

I’m a huge fan of ZFS because of its performance and other features like snapshots, transparent compression. In fact I had switched to FreeBSD for servers just because it had native ZFS support.

Securing FreeBSD server with Fail2Ban and IPFW

I’ve been playing with a FreeBSD machine for a while now and my primary server now runs FreeBSD 😀So I came across this problem: installing Fail2Ban with IPFW.
