Projects / OpenBSD


The OpenBSD project produces a free, multi-platform 4.4BSD-based UNIX-like operating system. Its goals emphasize portability, standardization, correctness, proactive security, and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS, and HP-UX.

            underdog, underrated, under the radar OS
            This OS is awesome. It is the most secure and stable OS I have ever seen. It runs exceedingly well on ancient equipment, and installs in about ten minutes. No extra cruft. No kitchen sink. Just a nice tight BSD UNIX OS. Very killer firewall package (pf) built in.

            Oh, BTW, 3.1 is out now and unfortunately was not announced here. I'm running it on a firewall with 10 ethernet adapters and it is just rock solid.
