The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography.

OpenBSD is a full-featured UNIX-like operating system available in source and binary form at no charge. OpenBSD integrates cutting-edge security technology suitable for building firewalls and private network services in a distributed environment.

This book covers many fundamental tasks in system administration. It includes examples for a wide range of Unix operating systems, including BSD.

If you have a running OpenBSD system, bsd.rd is all you need to reinstall or upgrade to a newer version. To do so, download and verify the new bsd.rd, place it on an existing filesystem, and boot from it.

OpenBSD/zaurus: Using the Linux built-in graphical ipkg installer, install the openbsd42_arm.ipk package. Reboot, then run it. Read INSTALL.zaurus for a few important details.

Aug 21, 2021 · The UNIX -domain protocol family is a collection of protocols that provides local (on-machine) interprocess communication through the normal socket (2) mechanisms.

OpenBSD can be obtained via HTTP (s) or FTP. Typically you only need a single small piece of boot media and then the rest of the files can be installed from a number of locations, including directly off the internet. Consult the installation guide for details.

Apr 1, 2024 · The nc (or netcat) utility is used for just about anything under the sun involving TCP, UDP, or UNIX -domain sockets. It can open TCP connections, send UDP packets, listen on arbitrary TCP and UDP ports, do port scanning, and deal with both IPv4 and IPv6.

History: VAX has been a supported OpenBSD architecture since early 2000, when code was synchronized with NetBSD's port. Being the second architecture to run BSD Unix (in 1979!), it seems appropriate that these venerable vaxen should still have a modern OS.

Goals OpenBSD believes in strong security. Our aspiration is to be NUMBER ONE in the industry for security (if we are not already there). Our open software development model permits us to take a more uncompromising view towards increased security than most vendors are able to. We can make changes the vendors would not make. Also, since OpenBSD is exported with cryptography, we are able to take ...
