Chris Benedict NetBSD's Linux emulation doesn't run a Linux kernel on a virtual machine; Linux emulation let you run plenty of useful programs that won't run natively under NetBSD, such as Sun's 14 Java Runtime Environment and JDK. Setting up Linux emulation requires a kernel option (COMPAT_LINUX) in the NetBSD kernel, and some local files. The kernel option is specified in the default GENERIC configuration; As for the Linux programs, most are dynamically linked and thus need copies of Linux shared libraries, which are installed under /emul/linux.
Dan Langille BSDCan registration was scheduled to close yesterday (Monday) but has been extended until Thursday May 13 at noon (EST). People are coming from England, Japan, Germany, Ukraine, Holland, and of course, Canada and USA. I personally know of people planning 40 hour (one way) car trips to get here. It is late spring in Ottawa and the temperatures for this weekend should range from 18C to 25C. Perfect weather for sitting outside and having a beverage.
Kernel Trap 11 May 2004 Submitted By : njc Kqueue, the scalable facility for event notification in the FreeBSD kernel, has experienced various performance and stability issues over the last several months. This has largely been fallout from the ongoing introduction of fine-grained locking into kernel subsystems and kqueue's reliance on GIANT, further complicated by an abundance of entangled callback routines. There has recently been some discussion on the freebsd-arch list concerning kqueues shortcomings and potential areas for redesign. In mid-April, Brian Feldman Fundakowski submitted controversial proof-of-concept code that relieves kqueue of some of its less utilized features and adds an internal global lock into the kqueue subsystem.
To better understand the reality of this threat, KernelTrap spoke with Theo de Raadt, the creator of OpenBSD, an operating system which among other goals proactively focuses on security. In this article, we aim to provide some background into the workings of TCP, and then to build upon this foundation to understand how resets attacks work. The second article will look into how TCP stacks can be hardened to defend against such attacks. Toward this goal, we spoke with members of the OpenBSD team to learn what they have done so far, and what further plans they have to minimize the impact of reset attacks.
Wes Peters Bill Joy is joining FORTUNE as an editorial advisor, FORTUNE managing editor Rik Kirkland announced today. The Sun Microsystems founder will consult with FORTUNE editors about science and technology coverage, among other topics, and on occasion write columns and stories for the magazine. "Bill Joy's ideas helped lay the groundwork for the technology boom," said Kirkland. "He's an original thinker with an insatiable curiosity and an unparalleled range of interests. Bill's expertise and ability to see around corners will make FORTUNE's already strong science and technology coverage even stronger." Bill Joy was a founder of Sun Microsystems and led its technology strategy as Chief Scientist and Corporate Executive Officer until his retirement in 2003. While at Sun, Joy designed many of Sun's key technologies, including Solaris, SPARC and Java. Prior to founding Sun, while at UC Berkeley, Joy designed and implemented the Berkeley version of UNIX (BSD) and pioneered "open source" software.
It currently supports infrastructure mode only (connection through an access point). IBSS (adhoc) mode , WEP and power management are not yet supported but the driver is under active development. It is not a port of the Intel ipw2100 driver for Linux but a complete rewriting from scratch. As stated above, this is a first release and the driver is under active development so do not expect too much stability from it.
Chris Benedict In a previous article we built a tiny OpenBSD system out of a Soekris miniature PC, a bootstrap workstation, and a Compact Flash (CF) card. While this combination works nicely for many purposes, once you have Soekrii scattered all around your network, managing the CF cards can be annoying. Replacing the CF cards with a diskless boot system eases management problems. One modest server can manage many small diskless devices, and it's possible to do much of the system administration on the server instead of on the devices.
