“As you already may now, last half a year I’ve been working on making pf SMP-scalable and faster in general. More info can be found here:
Since that announce in June, I’ve been running experimental code for more than 2 months in production on several routers. Also, some brave people volunteered to be beta-testers and also run the experimental branch in last couple of months. Code proved to be stable enough.
The new code performs better in production: less CPU load, less jitter, more responsive system under high load. It performs better under synthetic benchmarks like random generated UDP flood. It performs much better when DoS comes in.”
We are now living in an age of cloud computing and sharing content and news, privately and publicly. However, it seems cloud companies struggle to keep our data private and don’t seem to always respect users’ privacy, so why not set up your own cloud?
If you want to stay in control of your own data and share it only with those you want to share it with, have a look at ownCloud. Kris Moore from the PC-BSD Project has an article showing how to set up ownCloud on PC-BSD. Very useful.

Setting up Your OwnCloud Instance via the Warden™
In this article we will be taking a look at the OwnCloud software, specifically how to do the initial installation and configuration inside a jail run by PC-BSD’s® jail management utility, the Warden™. First we will take a look at a setup done from a PC-BSD graphical interface, and then explore the same setup from the command-line using TrueOS™, the server version of PC-BSD.
Nmap: The Network Swiss Army Knife
Nmap (“Network Mapper”) is a GPL utility for network discovery and security auditing. Many systems and network administrators find it very useful for network inventory, monitoring hosts and services uptime, debugging network related problems, and many other tasks. From this article you will learn the basic functionalities of Nmap 6.
Unix IPC with Pipes
This article explains one of the earliest forms of inter-process communication (IPC) in Unix. Pipes were the original form of Unix IPC and were present in Third Edition of Unix (1973). They can only be used to communicate between related processes, but despite this limitation they still remain one of the most frequently employed mechanisms for IPC.
FreeBSD Enterprise Search with Apache Solr
Back office integration and cross platform search has always posed major challenges especially in large organizations with many legacy systems. With Apache Solr these barriers can be overcome and the power of enterprise search realised. In this new series the author will show you step by step how to commission an Apache Solr search engine.
Hardening FreeBSD with TrustedBSD and Mandatory Access Controls (MAC)
Most system administrators understand the need to lock down permissions for files and applications. In addition to these configuration options on FreeBSD, there are features provided by TrustedBSD that add additional layers of specific security controls to fine tune the operating system for multilevel security. By reading this article you will learn the configuration of the mac_bsdextended module and how to use the ugidfw utility
Interview with Jeroen van Nieuwenhuizen
Jeroen van Nieuwenhuizen was the chair of the EuroBSDcon 2011 organizing committee. Currently, he is one of the members of the EuroBSDcon Foundation board. He came in contact with Unix in 1997 and started to work with the BSDs in 2002. In his daily life Jeroen works as a Unix Consultant for Snow B.V. BSD Magazine asked him some questions regarding event organization and opportunities to participate in organizing EuroBSDcon.
BSD Magazine has also a “Best of 2011? issue available for purchase.

Tuning ZFS on FreeBSD
By Martin Matuska
ZFS is a modern 128-bit file system based on the copy-on-write model. It originates from the OpenSolaris project and has first appeared in FreeBSD in 2008. ZFS has many innovative features including an integrated volume manager with mirroring and RAID capabilities, data checksumming and compression, writable snapshots that can be transferred between systems and many more. In this article the author is going to discuss several tuning options including sysctl(2) knobs and give examples how can ZFS performance and efficiency can be measured and evaluated. This article is intended for FreeBSD users with ZFS version 28 available since 8.3-RELEASE and 9.0-RELEASE.
