  • Accessing Windows Applications from Unix and Vice Versa

This implies that even if eventually migrating to another environment, one still has to deal with coexistence among environments in the interim. In many com- panies it would make good business sense not to migrate legacy systems at all. Instead, it may be better to develop new systems in the desired en- vironment and phase out the legacy applications. The data created by the legacy applications is important and one must ensure that data can be ac- cessed from a new environment. Coexistence considerations are very im- portant in this case. Coexistence between Windows PAYOFF IDEA NT, UNIX, and NetWare deals with a Some users want applications they develop in number of related issues.

  • Xfree86(1) Xfree86(1)
    XFree86(1) XFree86(1) NAME XFree86 - X11R6 X server SYNOPSIS XFree86 [:display][option ...] DESCRIPTION XFree86 is a full featured X server that was originally designed for UNIX and UNIX-likeoperating sys- tems running on Intel x86 hardware. It nowruns on a wider range of hardware and OS platforms. This work was originally derivedfrom X386 1.2 by Thomas Roell which was contributed to X11R5 by Sni- tily Graphics Consulting Service. The XFree86 server architecture was redesigned for the 4.0 release, and it includes among manyother things a loadable module system derivedfrom code donated by Metro Link, Inc. The current XFree86 release is compatible with X11R6.6. PLATFORMS XFree86 operates under a wide range of operating systems and hardware platforms. The Intel x86 (IA32) architecture is the most widely supported hardware platform. Other hardware platforms include Compaq Alpha, Intel IA64, SPARC and PowerPC. The most widely supported operating systems are the free/Open- Source UNIX-likesystems such as Linux, FreeBSD, NetBSD and OpenBSD. Commercial UNIX operat- ing systems such as Solaris (x86) and UnixWare are also supported. Other supported operating systems include LynxOS, and GNU Hurd. Darwin and Mac OS X are supported with the XDarwin(1) X server. Win32/Cygwin is supported with the XWin X server. NETWORK CONNECTIONS XFree86 supports connections made using the following reliable byte-streams: Local On most platforms, the "Local" connection type is a UNIX-domain socket. On some System V plat- forms, the "local" connection types also include STREAMS pipes, named pipes, and some other mechanisms. TCP IP XFree86 listens on port 6000+n,where n is the display number.This connection type can be disabled with the −nolisten option (see the Xserver(1) man page for details).

Quizzes and tests may refer to work done in this Worksheet and Assignment; save your answers. You will use a checking program at the end of the assignment to verify the correctness of your work. You must upload the check program results before the due date. Before you get started - REMEMBER TO READ ALL THE WORDS You must have your own Fedora 12 virtual machine (with root permissions) running to do this lab. You cannot do this assignment on the Course Linux Server because you do not have root permissions on that machine. Disks, Partitions, and File Systems 1 Commands, topics, and features covered Use the on-line help (man command) for the commands listed below for more information. ➢ df – show mounted partitions and amount of used/free space ➢ du – recursively display disk usage in directories ➢ eject – unmount and eject a CDROM ➢ fdisk – to display, create, delete, and manage partitions; option -l is very useful ➢ file – determine what kind of thing a pathname is. Can show partition file system types using option -s and will follow (dereference) symbolic links using option -L (upper case) ➢ mkfs – create a file system on a device, usually a hard disk partition. ➢ mkswap – initialize a partition for use as a Linux swap partition. ➢ mount – mount a file system existing on some device into the main file system tree. ➢ swapon – tell the Linux kernel to use an initialized swap partition.
