Book Review: FreeBSD Mastery: Storage Essentials

samzenpus posted about two weeks ago | from the read-all-about-it dept.

Books 75

Saint Aardvark writes If, like me, you administer FreeBSD systems, you know that (like Linux) there is an embarrassment of riches when it comes to filesystems. GEOM, UFS, soft updates, encryption, disklabels — there is a *lot* going on here. And if, like me, you're coming from the Linux world your experience won't be directly applicable, and you'll be scaling Mount Learning Curve. Even if you *are* familiar with the BSDs, there is a lot to take in. Where do you start? You start here, with Michael W. Lucas' latest book, FreeBSD Mastery: Storage Essentials. You've heard his name before; he's written Sudo Mastery (which I reviewed previously), along with books on PGP/GnuPGP, Cisco Routers and OpenBSD. This book clocks in at 204 pages of goodness, and it's an excellent introduction to managing storage on FreeBSD. From filesystem choice to partition layout to disk encryption, with sidelong glances at ZFS along the way, he does his usual excellent job of laying out the details you need to know without every veering into dry or boring. Keep reading for the rest of Saint Aardvark's review.

Ask Slashdot: Migrating a Router From Linux To *BSD?

timothy posted about two weeks ago | from the hiring-a-new-traffic-cop dept.

Networking 403

An anonymous reader writes I'm in the camp that doesn't trust systemd. You can discuss the technical merits of all init solutions all you want, but if I wanted to run Windows NT I'd run Windows NT, not Linux. So I've decided to migrate my homebrew router/firewall/samba server to one of the BSDs. Question one is: which BSD? Question two: where's some good documentation regarding setting up a home router/firewall on your favorite BSD?
It's fine if the documentation is highly technical, I've written linux kernel drivers before :)

OpenBSD's Kernel Gets W^X Treatment On Amd64

Soulskill posted about two weeks ago | from the write-stuff dept.

Operating Systems 84

New submitter brynet tips this news from Theo de Raadt: Over the last two months Mike Larkin (mlarkin@) modified the amd64 kernel to follow the W^X principles. It started as a humble exercise to fix the .rodata segment, and kind of went crazy. As a result, no part of the kernel address space is writeable and executable simultaneously. At least that is the idea, modulo mistakes. Final attention to detail (which some of you experienced in buggy drafts in snapshots) was to make the MP and ACPI trampolines follow W^X, furthermore they are unmapped when not required. Final picture is many architectures were improved, but amd64 and sparc64 look the best due to MMU features available to service the W^X model. The entire safety model is also improved by a limited form of kernel ASLR (the code segment does not move around yet, but data and page table ASLR is fairly good."

Ask Slashdot: Workaday Software For BSD On the Desktop?

timothy posted about 2 months ago | from the clever-little-devil dept.

Operating Systems 267

An anonymous reader writes So for a variety of reasons (some related to recent events, some ongoing for a while) I've kinda soured on Linux and have been looking at giving BSD a shot on the desktop. I've been a Gentoo user for many years and am reasonably comfortable diving into stuff, so I don't anticipate user friendliness being a show stopper. I suspect it's more likely something I currently do will have poor support in the BSD world. I have of course been doing some reading and will probably just give it a try at some point regardless, but I was curious what experience and advice other slashdot users could share. There's been many bold comments on slashdot about moving away from Linux, so I suspect I'm not the only one asking these questions. Use-case wise, my list of must haves is: Minecraft, and probably more dubiously, FTB; mplayer or equivalent (very much prefer mplayer as it's what I've used forever); VirtualBox or something equivalent; Firefox (like mplayer, it's just what I've always used, and while I would consider alternatives, that would definitely be a negative); Flash (I hate it, but browsing the web sans-flash is still a pain); OpenRA (this is the one I anticipate giving me the most trouble, but playing it is somewhat of an obsession).

Stuff that would be nice but I can live without: Full disk encryption; Openbox / XFCE (It's what I use now and would like to keep using, but I could probably switch to something else without too much grief); jackd/rakarrack or something equivalent (currently use my computer as a cheap guitar amp/effects stack); Qt (toolkit of choice for my own stuff).
What's the most painless way to transition to BSD for this constellation of uses, and which variety of BSD would you suggest?

FreeBSD 10.1 Released

OpenBSD 5.6 Released

timothy posted about 3 months ago | from the making-the-world-a-better-place dept.

Operating Systems 125

An anonymous reader writes Just as per the schedule, OpenBSD 5.6 was released today, November 1, 2014. The theme of the 5.6 release is "Ride of the Valkyries". OpenBSD 5.6 will be the first version with LibreSSL. This version also removed sendmail from the base system, smtpd is the default mail transport agent (MTA). The installer no longer supports FTP, network installs via HTTP only. The BIND name server will be removed from the OpenBSD base system. Its replacement comes in the form of the two daemons nsd(8) for authoritative DNS service and unbound(8) for recursive resolver service. OpenSSH 6.7 is included along with GNOME 3.12.2, KDE 4.13.3, Xfce 4.10, Mozilla Firefox 31.0, Vim 7.4.135, LLVM/Clang 3.5 and more. See a detailed log of changes between the 5.5 and 5.6 releases for more information. If you already have an OpenBSD 5.5 system, and do not want to reinstall, upgrade instructions and advice can be found in the Upgrade Guide (a quick video upgrade demo is here). You can order the 5.6 CD set from the new OpenBSD Store and support the project.

OpenBSD Drops Support For Loadable Kernel Modules

Soulskill posted about 3 months ago | from the loadable-kernel-modules-have-had-it-too-good-for-too-long dept.

Open Source 162

jones_supa writes: The OpenBSD developers have decided to remove support for loadable kernel modules from the BSD distribution's next release. Several commits earlier this month stripped out the loadable kernel modules support. Phoronix's Michael Larabel has not yet found an official reason for the decision to drop support. He wagers that it is due to security or code quality/openness ideals.

Fork of Systemd Leads To Lightweight Uselessd

timothy posted about 4 months ago | from the not-big-and-fancy dept.

Open Source 469

An anonymous reader writes A boycott of systemd and other backlash around systemd's feature-creep has led to the creation of Uselessd, a new init daemon. Uselessd is a fork of systemd 208 that strips away functionality considered irrelevant to an init system like the systemd journal and udev. Uselessd also adds in functionality not accepted in upstream systemd like support for alternative C libraries (namely uClibc and musl) and it's even being ported to BSD.

GSOC Project Works To Emulate Systemd For OpenBSD

timothy posted about 5 months ago | from the everyone's-idea-of-a-good-time dept.

Emulation (Games) 314

An anonymous reader writes Through a Google Summer of Code project this year was work to emulate systemd on OpenBSD. Upstream systemd remains uninterested in supporting non-Linux platforms so a student developer has taken to implementing the APIs of important systemd components so that they translate into native systemd calls. The work achieved this summer was developing replacements for the systemd-hostnamed, systemd-localed, systemd-timedated, and systemd-logind utilities. The hope is to allow for systemd-dependent components like more recent versions of GNOME to now run on OpenBSD.

Facebook Seeks Devs To Make Linux Network Stack As Good As FreeBSD's

timothy posted about 6 months ago | from the high-praise-all-around dept.

Facebook 195

An anonymous reader writes Facebook posted a career application which, in their own words is 'seeking a Linux Kernel Software Engineer to join our Kernel team, with a primary focus on the networking subsystem. Our goal over the next few years is for the Linux kernel network stack to rival or exceed that of FreeBSD.' Two interesting bullet points listing "responsibilities": Improve IPv6 support in the kernel, and eliminate perf and stability issues. FB is one of the worlds largest IPv6 deployments; Investigate and participate in emerging protocols (MPTCP, QUIC, etc) discussions,implementation, experimentation, tooling, etc.

OpenBSD 5.5 Released

timothy posted about 9 months ago | from the always-just-in-time dept.

Operating Systems 128

ConstantineM (965345) writes "Just as per the schedule, OpenBSD 5.5 was released today, May 1, 2014. The theme of the 5.5 release is Wrap in Time, which represents a significant achievement of changing time_t to int64_t on all platforms, as well as ensuring that all of the 8k+ OpenBSD ports still continue to build and work properly, thus doing all the heavy lifting and paving the way for all other operating systems to make the transition to 64-bit time an easier task down the line. Signed releases and packages and the new signify utility are another big selling point of 5.5, as well as OpenSSH 6.6, which includes lots of DJB crypto like chacha20-poly1305, plus lots of other goodies."

Lumina: PC-BSD's Own Desktop Environment

timothy posted about 9 months ago | from the always-room-for-one-more dept.

GUI 148

jones_supa (887896) writes "The PC-BSD project is developing a new open source (BSD license) desktop environment from scratch. The name of the project is Lumina and it will be based around the Qt toolkit. The ultimate goal is to replace KDE as the default desktop of PC-BSD. Lumina aims to be lightweight, stable, fast-running, and FreeDesktop.org/XDG compliant. Most of the Lumina work is being done by PC-BSD's Ken Moore. Even though Lumina is still in its early stages, it can be built and run successfully, and an alpha version can already be obtained from PC-BSD's ports/package repositories."

OpenBSD Team Cleaning Up OpenSSL

Security 304

First time accepted submitter Iarwain Ben-adar (2393286) writes "The OpenBSD has started a cleanup of their in-tree OpenSSL library. Improvements include removing "exploit mitigation countermeasures", fixing bugs, removal of questionable entropy additions, and many more. If you support the effort of these guys who are responsible for the venerable OpenSSH library, consider a donation to the OpenBSD Foundation. Maybe someday we'll see a 'portable' version of this new OpenSSL fork. Or not."

Yes, You Too Can Be an Evil Network Overlord With OpenBSD

Unknown Lamer posted about a year ago | from the using-pflow-for-fun-and-profit dept.

Networking 49

badger.foo writes "Have you ever wanted to know what's really going on in your network? Some free tools with surprising origins can help you to an almost frightening degree. Peter Hansteen shares some monitoring insights, anecdotes and practical advice in his latest column on how to really know your network. All of it with free software, of course." From the article: " The NetFlow protocol was invented at Cisco in the early 1990s. It's designed to collect traffic metadata, where the basic unit of reference is the flow, defined as the source and destination IP address pair, the matching source and destination port for protocols that use them, the protocol identifier, time started and ended, number of packets sent, number of bytes sent, and a few other fields that have varied somewhat over the NetFlow versions. ... On OpenBSD, various netflow sensors and collectors had been available for a while when the new network pseudo device pflow debuted in OpenBSD 4.5."

BSD Real-Time Operating System NuttX Makes Its 100th Release: NuttX 6.33

paugq writes "NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOS's (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments. NuttX was first released in 2007 by Gregory Nutt under the permissive BSD license, and today the 100th release was made: NuttX 6.33. Supported platforms include ARM, Atmel AVR, x86, Z80 and others."
