Performance of kernel to user space transitions for access to DNS address helper routines when given "implicit" mounts (e.g. "dfs" junctions) How effective is skipping NBT in reducing WINS related denial of service attacks? CoasesPenguin http://www.benkler.org/CoasesPenguin.PDF For decades our common understanding of the organization of economic production has been that individuals order their productive activities in one of two ways: either as employees in firms, following the directions of managers, or as individuals in markets, following price signals. This dichotomy was first identified in the early work of Ronald Coase and was developed most explicitly in the work of institutional economist Oliver Williamson. The phenomenon of large and medium scale collaborations among individuals, organized without markets or managerial hierarchies, is emerging everywhere in the information and cultural production system. Where agents, effort, or resources cannot so be specified, they cannot be accurately priced or managed. Linux+IPv6-HOWTO http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/pdf/Linux+IPv6-HOWTO.pdf The goal of the Linux IPv6 HOWTO is to answer both basic and advanced
questions about IPv6 on the Linux operating system.
Success requires good alignment between the requirements of the workload, the capabilities of the IT organization, and the attributes of Linux (cost, performance, reliability, manageability, applications availability, and vendor support). This is likely because of higher incidence of multiple workloads aboard RISC/Unix and its generally more complex configuration (including ERP, database, and other complex workloads), whereas a Linux server's workloads will often be more simplistic in nature (print and file, Web serving, Internet and network infrastructure workloads). RFG-LinuxTCO-vFINAL-Jul2002 http://www.ibm.com/linux/RFG-LinuxTCO-vFINAL-Jul2002.pdf Through numerous conversations with IT executives, RFG learned that Linux server deployments are well under way, in many cases with notable cost savings from those implementations. RFG found that Linux was the least expensive platform to deploy and operate. Although some initial costs were higher at points, the ability to massively scale the product horizontally without paying additional licensing fees can yield significant cost savings over the long term. Costs for system downtime due to breaches of security varied wildly across the study participants. 3. The cost per hour of downtime for a given system. Survey data showed that Windows installations require twice the number of administrator hours on average spent patching systems and dealing with other security-related issues than either Solaris or Linux. PA-RISC-Linux-Boot-HOWTO Revision 0.3 draft 1999-11-24 Revised by: dlr This document outlines the procedures to get the PA-RISC/Linux kernel to boot on your PA-RISC system. After listing the supported hardware, this HOWTO explains some commands of the basic console available at boot time. A console is basically the device where the kernel (and the firmware) will display its output, and where your can send your input to control the system at an early boot stage. You can use either graphic console, which requires to have a monitor and a keyboard attached to the system, or serial console, which allows serial communication between the system and another Linux machine, or any VT system. manual.sunlinux Sun Microsystems, Inc. has intellectual property rights relating to technology embodied in the product that is described in this document. This document and the product to which it pertains are distributed under licenses restricting their use, copying, distribution and decompilation, and are for use only with this product. This User Guide is for anyone who may need to install, set up and configure Sun Linux on the Sun Cobalt(TM) LX50 server, or perform a Linux(TM) rescue operation. The PS/2 mouse and keyboard use the back-panel PS/2 connector plus a 1:2 divider dongle. If you choose to develop your own RJ-45-to-DB9 adapter, see Table 4 for the appropriate pinout configuration. SLES_concept http://www.suse.com/en/company/press/services/brochures/SLES_concept.pdf "SuSE Linux Enterprise Server, leveraging the integrated enterprise capabilities of IBM xSeries, IBM iSeries, IBM pSeries und IBM zSeries, represents a powerful, stable, and secure platform achieving high marks for reliability while maintaining a low total cost of ownership. Linux, the world's fastest-growing server operating system, is an established standard in numerous enterprises. High-performance support of various hardware architectures and extreme reliability make SuSE Linux Enterprise Server the ideal medium for consolidating complex server structures -- from department and Internet/intranet servers to application servers for mission-critical applications. For example, release cycles of one year provide planning security. And by combining this with release maintenance periods adapted to customer needs, SuSE ensures investment security, thus stabilizing the dynamics of the Linux world. Aleph_1_pages Booting on any device needs a boot-loader and some means to get the boot-loader installed in the first place. To boot Linux, the boot-loader has to load two things into memory; the Linux kernel ('kernel') and a root filesystem ('root') for it to use. That can be done with an oldfashioned ROM or EEPROM, but on modern ARM platforms it is done using a JTAG up-loader. Target part stored in flash loads images over serial interface. During normal booting it loads the kernel and RAMdisk from RAM before handing over to the kernel.

In benchmarking a web server, the aim is typically to determine the number of requests per second the server is able to sustain, whilst satisfying certain constraints. Now estimate the highest number of requests per second that your test server or servers can sustain. For example, if you were to assume that the web server would be saturated by 1500 requests per second, and you were sending 10 requests down each connection, then you would set --rate to 150. Linux1 Believe it or not, it's quite easy to get upwards of 1000% database improvement through proper Linux tuning and database configuration for Linux. In this first issue, we'll review some very high ROI approaches. The first thing anyone should do to Linux after the install is to create a monolithic kernel (i.e. recompile the kernel to statically include libraries you intend to use and to turn off dynamically loaded modules). Another area that comes to mind regarding IO is the Linux virtual memory subsystem. The second parameter 1200 ndirty This gives the maximum number of dirty buffers that bdflush can write to the disk in one time. linux_http_benchmarking http://support.zeus.com/doc/tech/linux_http_benchmarking.pdf It seeks to identify some of the common pitfalls that can lead to erroneous results, and provides advice on tuning web server systems for optimum performance.

IntroToLinuxSeminar Linus was studying Minix, a simple UNIX variant, created by Andrew Tannenbaum during his time in school. In 1991 Linus had a working kernel and Richard had some basic UNIX utilities. The software includes X11, shells, Window Managers, programming tools, and other utilities. In a non-graphical UNIX system the shell is your primary way for interacting with the system. su Use this command to become root, with the password of course. Single user mode, or run level 0 is used for console maintenance (i.e. when there are hard disk problems). Along with its contents, a file has a name and some 'metadata,' its permissions and its creation/ modification date. | ||
