NetBSD Non-executable Mappings Update

During the last few months Chuck Silvers has refined the support for non-executable mappings on NetBSD. Non-executable mappings make parts of the stack and heap non-executable when they are marked writable. This makes exploiting potential buffer overflows harder.

First NetBSD Quarterly Status Report for 2004

Jan Schaumann announced today that, in order to provide a summary of the most important changes over the last few months, the NetBSD Foundation has decided to follow the example of other projects of releasing official status reports on a regular basis. The first quarterly status report, covering the activities within the NetBSD Project during the first three months of 2004 is now available online.

OS Review: NetBSD 1.6.2 on SPARC64

NetBSD is the king of operating system portability, running on 40+ different hardware platforms, including x86, MIPS, and even the Sega Dreamcast. So it comes as no surprise that among the supported platforms, NetBSD runs on my Sun Ultra 5. This will be the first in a series of operating system reviews for the SPARC platform. You can find the specifics of my evaluation machine here.

NetBSD Packages Collection on Interix

Preliminary support for Interix, a UNIX-like environment for Microsoft Windows 2000, XP, and 2003, has been added to NetBSD's Packages Collection. The support is still new and incomplete, but it is now possible to bootstrap pkgsrc and install simple packages. Interix is part of Microsoft's Windows Services for UNIX package. See Todd Vierling's email to the tech-pkg mailing list for more information.

A daemon-writer’s Guide to NetBSD’s rc.d system; Logo Contest

The NetBSD startup process is extensible, flexible, and a little daunting at first. This article looks at the configuration mechanisms used to enable or disable features, and compares NetBSD's startup procedures to those of other systems. The NetBSD Project has also announced that it has launched an international competition for the creation of a new logo. The cash prize is US $100 for the winning entry. Our Take: I hope the winning entry resizes well (see: it is clear enough) at 32x32pix, so we can update our NetBSD logo here at OSNews too.

NetBSD Packages Collection gets (experimental) “pkgviews”

NetBSD's Packages Collection aka pkgsrc now has support for an experimental new framework called ``pkgviews''. This framework, finally allowing multiple versions of one package to co-exist without conflicts (among other great features), was first proposed by Alistair Crooks at EuroBSDCon 2002 and has been integrated into pkgsrc by Johnny C. Lam, who just posted a User's guide to the tech-pkg ml.
