EDITOR’S WORD Dear Readers, It is nice to meet you again and present to you with the next BSD issue. I hope you will find the articles interesting and eventually learn many useful tips and tricks. This time, I want to focus on short but useful hints that will help you in your daily tasks. Enjoy reading and share your thoughts with me. For those of you who prefer to visit our website, I want to start publishing some of the articles from the BSD magazine online on our blog. I am doing this for convenience purposes so that those of you who do not have time to read the issue all at once but prefer to visit our website more often to search easily for the most-wanted information can do so with ease. If you have your favourite articles that you think should be published, please feel free to contact me. Also, I plan to organise a contest to choose the best articles that were written in the first half of 2017. I hope you like the idea and you will take part in it. I will publish more details on the BSD magazine website and in our newsletter. That’s all for my announcements, but I would like to add that I’m still looking for new ideas for topics on articles. I look forward to your emails and your suggestions on what is new and trending. You can always reach me at [email protected]. Having said that, let us now see what we have inside this BSD magazine issue. Carlos will refresh his own article for you to remind you about debugging skills. In his tutorial, he used a real life situation where debugging skills will save us time, headaches and possibly find a solution with a minimal amount of effort. For those of you who want to know more about DevOps, please go to E.G Nadhan. He will explain what he has in mind. The definition that he compiled is based upon myriad interpretations that he has come across in his interactions with his peers, as well as customers, partners, service providers and colleagues t colleagues over social media. I would like to highlight two articles for this month. The first one is ZFS Feature Flags written by Natalia Portillo. It is a great article which offers an easy explanation for those who want to know more about ZFS feature flags. The second one was written by Abdorrahman Homaei entitled SSH Hardening with Google Authenticator and OpenPAM. From this article, you will learn about techniques one of which is called 2-Step Verification.

  • Pluggable Authentication Modules

    Pluggable Authentication Modules

    Who this book is written for This book is for experienced system administrators and developers working with multiple Linux/UNIX servers or with both UNIX and Pluggable Authentication Windows servers. It assumes a good level of admin knowledge, and that developers are competent in C development on UNIX-based systems. Pluggable Authentication Modules PAM (Pluggable Authentication Modules) is a modular and flexible authentication management layer that sits between Linux applications and the native underlying authentication system. The PAM framework is widely used by most Linux distributions for authentication purposes. Modules Originating from Solaris 2.6 ten years ago, PAM is used today by most proprietary and free UNIX operating systems including GNU/Linux, FreeBSD, and Solaris, following both the design concept and the practical details. PAM is thus a unifying technology for authentication mechanisms in UNIX. This book provides a practical approach to UNIX/Linux authentication. The design principles are thoroughly explained, then illustrated through the examination of popular modules. It is intended as a one-stop introduction and reference to PAM. What you will learn from this book From Technologies to Solutions • Install, compile, and configure Linux-PAM on your system • Download and compile third-party modules • Understand the PAM framework and how it works • Learn to work with PAM’s management groups and control fl ags • Test and debug your PAM confi guration Pluggable Authentication Modules • Install and configure the pamtester utility
  • Why Did We Choose Freebsd?

    Why Did We Choose Freebsd?

    Why Did We Choose FreeBSD? Index Why FreeBSD in General? Why FreeBSD Rather than Linux? Why FreeBSD Rather than Windows? Why Did we Choose FreeBSD in General? We are using FreeBSD version 6.1. Here are some more specific features which make it appropriate for use in an ISP environment: Very stable, especially under load as shown by long-term use in large service providers. FreeBSD is a community-supported project which you can be confident is not going to 'go commercial' or start charging any license fees. A single source tree which contains both the kernel and all the rest of the code needed to build a complete base system. Contrast with Linux that has one kernel but hundreds of distributions to choose from, and which may come and go over time. Scalability features as standard: e.g. pwd.db (indexed password database), which give you much better performance and scales well for very large sites. Superior TCP/IP stack that responds well to extremely heavy load. Multiple firewall packages built in to the base system (IPF, IPFW, PF). High-end debugging and tracing tools, including the recently announced port of the Sun Dynamic Tracing tool, DTrace, to FreeBSD. Ability to gather fine-grained statistics on system performance using many included utilities like systat, gstat, iostat, di, swapinfo, disklabel, etc. Items such as software RAID are supported using multiple utilities (ata, ccd. vinum, geom). RAID-1 using GEOM Mirror (see gmirror) supports identical disk sets, or identical disk slieces. Take a look at the most stable web sites according to NetCraft (http://news.netcraft.com/archives/2006/06/06/six_hosting_companies_most_reliable_hoster_in_may.html).

    BSDCan 2015 UCL Working Group [email protected] Overview The goal of this working group is to develop a template for all future configuration files that is both human readable and writable, but is also hierarchical, expressive, and programmatically editable. Agenda ● Opening: What is UCL ● Presentation of work in progress: converting newsyslog and bhyve to UCL ● Discuss common requirements for configuration files ● Develop a common set of grammar/keys to work across all configuration files ('enabled' activates/deactivates each block, allows disabling default configuration without modifying the default files, ala pkg) Agenda (Continued) ● Discuss layering (/etc/defaults/foo.conf -> /etc/foo.conf -> /etc/foo.conf.d/*.conf -> /usr/local/etc/foo.conf.d/*.conf) ● Discuss required features for management utilities (uclcmd) ● Identify additional targets to UCL-ify ● Develop a universal API for using libucl in various applications, simplify loading configuration into C structs (libfigpar?) What is the Universal Configuration Language? ● Inspired by bind/nginx style configuration ● Fully compatible with JSON, but more liberal in what it accepts, so users do not have to write strict JSON ● Can Output UCL, JSON, or YAML ● Supports handy suffixes like k, mb, min, d ● Can be as simple or as complex as required ● Allows inline comments (# and /* multiline */) ● Validation and Schema support ● Supports includes, macros, and variables Why UCL is great -- all of this is valid param = value; key = “value”; flag = true; section { number = 10k string

Included in the base system is the tool chain, the set of programs used to build, debug and test software. FreeBSD has relied on the GNU tool chain suite for most of its history. This includes the GNU Compiler Collection (GCC) compiler, and GNU binutils which include the GNU "bfd" linker. These tools served the FreeBSD project well from 1993 until 2007, when the GNU project migrated to releasing its software under the General Public License, version 3 (GPLv3). A number of FreeBSD developers and users objected to new restrictions included in GPLv3, and the GNU tool chain became increasingly outdated. The January/February issue of the FreeBSD Journal is now available. Don't miss articles on The FreeBSD project migrated to Clang/LLVM for the compiler in Tracing ifconfig Commands, Storage FreeBSD 10, and most of GNU binutils were replaced with the ELF Tool Multipathing, and more.
