## 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 spkr(4).

> 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.
