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

brynet Re: Good documentation (402 comments)

Peter N. M. Hansteen's PF tutorial and books are recommended reads, Peter remains involved with the developers and the information stays relevant and useful. He also ensures that readers using other BSD systems, especially with older versions of pf, can learn just as much from it.

* The Book of PF, 3rd Edition, 2014 - ISBN: 978-1593275891
* http://home.nuug.no/~peter/pf/

Michael W Lucas is another author that writes books for both the BSD and sysadmin communities, similarly, he works closely with developers and users to release these short, yet all-encompassing tomes of information, covering a wide variety of topics.

https://www.michaelwlucas.com/...
* Absolute OpenBSD, 2nd Edition, 2013 - ISBN: 978-1593274764
* SSH Mastery, 2012 - ISBN: 978-1470069711
* Sudo Master, 2013 - ISBN: 978-1493626205

And of course, official documentation is great. The effort of many people working to improve, Jason McIntyre improving readability and overall quality, Ingo Schwarze's amazing work on mandoc(1) tools. OpenBSD's FAQ, which is usually the first step people take to learn more about the system, is maintained by Nick Holland.

OpenBSD Drops Support For Loadable Kernel Modules

brynet Re:In other news. (162 comments)

If any vendor has proprietary drivers for OpenBSD, they would undoubtedly be using better kernel interfaces directly. Especially for something like a driver for a hardware RAID controller. LKM(4) support has mostly been only "compile tested" for years. Nothing uses it seriously, at the time of it's removal.. the ports tree contained a single port making use of it.. a firmware flasher for some Dell systems.

OpenBSD Drops Support For Loadable Kernel Modules

brynet Re:Djeezus (162 comments)

Why? It mostly used for compat_linux(8) anyway, which is i386 only. Nobody was using mount_procfs(8) without the ancient -o linux option. It was broken for months before anyone noticed.

OpenSSH No Longer Has To Depend On OpenSSL

brynet Re:No RSA? (144 comments)

Support for RSA and (non-EC)DSA key types might be added eventually; even sooner if you sent patches.

OpenBSD's kernel gets W^X treatment on amd64

brynet brynet writes  |  about two weeks ago

brynet (3462983) writes "Theo de Raadt wrote:

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.

OpenBSD's new rcctl(8) utility, in -current for 5.7

brynet brynet writes  |  about 5 months ago

brynet (3462983) writes "OpenBSD 5.7 will include a new control utility, rcctl(8), for managing daemons/services. Manually creating /etc/rc.conf.local or rc.conf(5) will still be supported, however, this new method will make scripting configuration easier and provide an equivalent to service(8) on Linux and sysrc(8) on FreeBSD."
