http://www.cmu.edu/computing/documentation/linux_gs/linux.pdf have a PCI Ethernet card installed We recommend that you install Andrew-Linux using the boot disk image found at /afs/andrew/data/db/download/linux. All other partitions may be "logical drives" in an extended partition. If your network card is registered, verify your network information. If your machine has a SCSI card, setup the SCSI adapters. For more information about Zip drives and ports see "Ports and Devices, Disks, Partitions, and Drives" on page 9. To set the local root password: At the login: prompt, press Alt-F2 to change to the second virtual consol and then login at the new prompt with your Andrew ID and password. An xf86cfg window with pictures of the monitor, video card, PC, keyboard and perhaps a few other components. LinuxShell Every once in while you get to hear the litany that 'the command line' is 'out of date', 'arcane' and so on. The truth is: you can use Linux without knowing anything about the shell. The shell lets you put various special queuing characters between commands. The classical example to demonstrate the difference between ';' and '&&', and the usefulness of command queuing in general, is the compilation and installation of the Linux kernel. apros name will execute 'apropos name' (i.e. a search command for man pages) and pipe (|) the output of that command through 'egrep' which filters out all man pages from sections '3' and 'n', which usually are not of interest, but tend to mess up the output of the 'apropos' command. o98radio We are collaborating with the Woods Hole Oceanographic Institute (WHOI) to develop an innovative data collection and communication system for moorings that addresses this problem. Linux, a freely distributable clone of the Unix operating system, provides our data system with all the multi-user, multitasking, process protection and network support capabilities found in today's powerful desktop workstations. In addition to data collection, our Linuxbased computer also performs tasks necessary for transmitting data to the experimenter via low earth orbiting satellite. These tasks include tracking the communication satellites of interest, computing Doppler corrections to the transmit and receive radio frequencies, command and control of the radio hardware and position and time monitoring via GPS. alp-ch01-advanced-unix-programming-with-linux Lots of different editors are available for Linux, but the most popular and full-featured editor is probably GNU Emacs. A compiler turns human-readable source code into machine-readable object code that can actually run.The compilers of choice on Linux systems are all part of the GNU Compiler Collection, usually known as GCC. The debugger is the program that you use to figure out why your program isn't behaving the way you think it should.You'll be doing this a lot.5 The GNU Debugger (GDB) is the debugger used by most Linux programmers.You can use GDB to step through your code, set breakpoints, and examine the value of local variables. Do this by adding the -g switch on the compilation command line. linux-perspective As organisations begin to realise the full potential of Linux and the operating system continues to gain credibility as a reliable platform for a wide range of 32-bit applications, the number of Linux system installations is growing at a stellar rate. "Linux is ideally suited for use in web server farms, file and print functions and email consolidation. However, it's now being used for database applications and for clustering and grid computing." Interest in systems that embrace Open Standards is growing rapidly, as users realise the serious long-term disadvantages introduced by systems that leave them reliant on proprietary technologies and on support from a single vendor. wp_zseries http://store.sendmail.com/pdfs/whitepapers/wp_zseries.pdf This document --intended for IT managers, system administrators, and CIOs -- also examines the technical and business advantages of consolidating an entire messaging infrastructure on a single large-scale machine, and discusses key considerations in planning, sizing, and deploying a Sendmail architecture on a zSeries mainframe. To meet these demands -- while still turning a profit -- requires sound strategy, robust technology, and a messaging architecture that supports and incorporates both. Sendmail on Linux for zSeries combines products reflecting more than two decades of real-world deployment experience with the recognized standard for platform performance and reliability. In practice, this three-part process (message data sent, stored, and retrieved) translates to a set of tasks reflecting the complex, sometimes conflicting demands on the system -- which must be flexible and open to accommodate the evolving realities of Internet mail and the varied needs of users, administrators, and profit-minded executives, yet also provide tight control so that both message data and the network itself can be secured and monitored. S2561kba Processor, Memory and I/O time vary greatly with application Processor designs vary greatly in the balance of capacity across components which results in a wide range of relative capacity. S/390 is not for "Deep Computing" Most commercial applications range between CPU and Data intensity z/Series is very good at "data intense" work for many users. But isn't Linux SMP scalability limited to a 4 way?? Linuxstory http://www.leavcom.com/pdf/Linuxstory.pdf In the process, it has grown in popularity. However, Linux may have reached a turning point at which it can either address several important challenges or face problems that could limit future adoption. "If leading hardware vendors are willing to risk their credibility by endorsing and placing Linux systems in the market, it's easy for customers to conclude there must be something real about Linux." According to Dan Frye, director of IBM's Linux Technology Center, a chief concern among IT decision makers is that there are close to 200 Linux distributions and that the OS thus might fragment into multiple commercial flavors, as Unix did. META-FAQ Red Hat and Craftworks have Alpha distributions of Linux. Support for Sparc is stable, and Red Hat Linux is available for Sparc. Support for PowerPC is in development for multiple platforms, including Nubus and PCI Macintosh, Motorola Powerstack, IBM 830 and 850, and other platforms. Support for ARM, StrongARM, and MIPS is in various stages of completion, but don't hold your breath. To make submissions to the newsgroup, send mail to linux-announce@news.ornl.gov. Send mail to majordomo@vger.rutgers.edu with the single word help in the body of the message, and you will get mail explaining how to subscribe to the many Linux mailing lists there. Linux_TL_Opp_whitepaper Open Source software, and the Linux operating system in particular, are riding a wave of success. There are four main commercially available distributions of the Linux operating system on the market today. The company's business model is based upon selling software, not primarily services. While TurboLinux also sells the Linux operating system and provides a support channel, TurboLinux concentrates on the traditional and appliance server markets. TurboLinux is the leading Linux distribution in the Asia/Pacific market and is leveraging this success and expertise as it expands into North America and worldwide. For most, Linux coding is a labor of love with satisfaction driven by creating the best software possible. Amazon update Online retailer Amazon.com shaved millions of dollars from its technology costs last quarter by switching to the Linux operating system, a disclosure that could provide some guidance for other companies seeking to cut expenses in a stagnant economy. Linux, a 10-year-old clone of the Unix operating system and a competitor to Windows, burst onto the scene in the late 1990s and now is an established force in the computing industry even though many companies pushing it are faltering. A recent study found that Linux is more powerful than some versions of Unix, but Linux in businesses is used more often on lower-end servers than on the powerful machines at the heart of large companies. linux-cross http://www.tbcorp.com/docs/linux-cross.pdf Linux provides a natural development platform for these groups of people: cost of configuration is minimal, and the GNU tools may be built to target a variety of microprocessor architectures. All executable code is located in a segment called text. The option -Ttext 2000 tells the linker to link the application text segment (at location 0x2000 in this example). At some point during development, it will be necessary to turn this final ELF file into a binary or hex-record type of file for loading on our target. 4. With all of Linux and the GNU tools available in source code format, readers have a tremendous advantage over typical commercial environments, because they have reference code to study and possibly work with.
