OPNsense 21.7.5 released: FreeBSD security advisories and an issue with Intel-based ixgbe driver with “ifconfig -v” stalls keep this release rolling. Also note that OpenSSH was updated to version 8.8 which deprecates ssh-rsa usage which is mainly an issue for client access from the OPNsense system to the outside and can be amended as per the suggestions in the respective release notes.

Chimera Linux: a Linux distribution based on FreeBSD userland and LLVM: This project is still very early in its development, but it’s an interesting premise. It’s developed by Daniel Kolesa, who also contributes a lot to Void Linux, most notably the excellent POWER/PowerPC port of that excellent distribution.

FreeBSD Documentation: Papers We Love To Read: A lot of great papers have been written throughout the history of FreeBSD. For most of the features you see today in a modern FreeBSD Operating System there is a corresponding paper that was written during its development or after its inclusion to document its addition. Today, we’re looking at two of our favourite papers, trying to highlight their contribution to the FreeBSD Operating System.


What every IT person needs to know about OpenBSD Part 3: That packet filter: This series aims to highlight the project’s signature security features and development practices — razor-sharp focus on correct and secure code coupled with continuing code audit — as well as the project’s role as a source of innovation in security practices and an ‘upstream’ source for numerous widely-used components such as OpenSSH, PF, LibreSSL and others. Part 1 focused on the history, Part 2 focused on usage and user experience, and this final part will looks at that packet filter (PF).
