Interview

OpenBSD is great as an OS, but also for it's side projects. My mail server is using OpenSMTPD on OpenBSD. OpenSMTPD is very easy to configure compared to other MTA.

OpenBSD includes also a lot of various network tools that makes it a great choice for routers. At home I set up two APU2 in redundancy as personal router, as a commercial box replacement. Everything is included: CARP makes it easy to manage IP failover mechanism, of course the firewall pf, and other convenient tools like dhcpd and unbound.

BONUS: OpenBSD makes very easy to play beeper music, see .

To play the first notes of Bach's prelude in C minor (BWV 934) (transposed to A minor to ease the writing), you need two OpenBSD boxes with beepers, and pipe the two following strings on /dev/speaker on both computers at the exact same time.
