ClosedBSD

From Wikipedia, the free encyclopedia

ClosedBSD is a freeware derivative of FreeBSD aimed at providing firewall and Network Address Translation services, written by Joshua Bergeron. ClosedBSD also aims to be small in size, available as a floppy disk image at 1.4MB and as a CD-ROM ISO at 12.8MB. Despite its small size, the software includes a fully-functional ncurses-based interface.

One of the advantages of ClosedBSD is that it can run directly off a floppy disk or a CD-ROM, with no hard drive needed. It can also run on relatively old hardware; the diskette version needs a x86-based computer with 8MB of RAM, while the CD-ROM version needs 32MB of RAM.

The latest versions are 1.0B for the floppy and 1.0-RC1 for the CD.

ClosedBSD is freeware, in that it is released for at no cost. Only the binaries (the executable programs) are released, not the source code. The binaries are distributed under the terms of the BSD License, which is a free software license, but ClosedBSD is not free software because the source code is not available.
