Free parallels workstation for linux software for linux

Phrealon is a bootable linux CD based on Slackware Linux 8.0 (now 9.0)designed to allow the easy imaging of multiple workstations.

It utilizes the udpcast set of Linux tools to accomplish this.

Pocket Linux is an almost minimal, one floppy linux system designed to quickly convert PC workstation into secure linux-based workstation using ssh to connect to remote host (other networking clients are also supported).
It supports bootp for determining host IP and other network parameters (theres also manual configuration possible, but bootp is recommended).
In addition to workstations equipped with a network card (ethernet or arcnet), you can also use Pocket Linux on a PC equipped with a modem. Modem is automatically detected and then PPP connection is made.
The idea came up some time in 1996 or so. The distribution then was not perfect, but still it shown it was a great idea. It wasnt maintained for about year or so, until I took it up again in the early January 1998. After a complete rebuild Pocket Linux 2.00 was released. It soon gained a huge number of happy users, whose ideas helped its development.
The aim is to provide a small and efficient workstation that autoconfigures as much as possible and lets securely use the network from almost everywhere.
Current version is a nice attempt and future ones will enhance the automation and support for various network equipment and protocols, becoming a total solution. Future plans also include side projects like one floppy router.
In order to understand some of the config options its useful to know something about operations that are done during bootup (in order to automatically configure the network). These are, in order (the later attempts are made if the earlier ones dont set-up the network):
- attempt to setup the network using BOOTP
- attempt to reuse previous manual configuration
- modem detection
- attempt to setup modem conection
Most of the config options switches these operations on and off.
Main menu
You can choose the following network configuration commands from the main menu (only the ones that make sense in the present context are displayed):
- Options - allows setting few binary parameters controlling automatic network configuration and modem handling.
- BOOTP query - attempts to configure network (ethernet or arcnet) using BOOTP. Normally its automatically done during bootup, but this can be switched off.
- Manual configuration - allows manual setting of network configuration parameters (ethernet or arcnet).
- Detect modem - detects serial port the modem is on and its parameters (transfer rate, initialization commands).
- Dial PPP using predefined configuration - creates modem connection (PPP) using one of (up to ten) remembered configurations. By default only TPSA (0202122) configuration is remembered.
- Dial PPP using new configuration - creates new PPP configuration and sets up a modem connection using the newly created config.
- Disconnect PPP - disconnects modem connection.
- Mount /usr via NFS - mounts remote /usr filesystem via NFS. It will be automatically mounted during each Pocket Linux bootup if its turned on in configuration options.
- Exit - Do not config the network - exits the program without configuring the network.
Configuration options
There are following options available:
- Probe network with BOOTP - switches automatic BOOTP probing during bootup on and off. On by default.
- Reuse manual network configs - if on, an attempt is made to restore network configuration during bootup. Netconf remembers 10 most recent manual configurations along with network cards MAC addresses. If cards MAC address matches one of the remembered ones, assigned configuration is used. On by default.
- Automatically setup PPP - switches automatic attempt to create modem connection during bootup on and off. Its made with the first config on PPP configs list. On by default.
- Reuse modem configuration - if on, modem detection is not performed during bootup - instead most recently used modem configuration is used. Off by default.
- Pulse dialing - switches dialing mode used for modem connections between tone dialing (DTMF) and pulse dialing. Default is off (that is tone dialing).
- Automount disk partitions - switches on and off automatical disk partitions mounting (ext2 and vfat filesystems) and swap partition activation during bootup. On by default.
- Add swap file if low memory - switches on and off automatical swap file creation during bootup. Swap file is created if, and only if, theres less than 16 MB memory available (including potentially activated swap partitions) and theres a disk partition on which it could be created available. On by default.
- Automount NFS /usr - switches on and off /usr filestem mounting via NFS during bootup. NFS path to the filestem must be set using "Mount /usr filesystem via NFS" command in main menu. Off by default.
Manual network card configuration
You can enter network configuration parameters in this window:
- This machines IP - enter IP number for this computer here
- Network mask - enter netmask here. If omitted, mask will be calculated based on IP (which will not necessarily be right).
- Broadcast address - enter network broadcast address here. If omitted broadcast address will be calculated based on IP (not mask! - which will not necessarily be right).
- Default gateway - enter IP address of default network gateway (router) here.
- Nameserver IP(s) - enter one or more (separated by spaces) name servers IP addresses here. Can be omitted, but then domain names couldnt be used.
- Default domain(s) - you can enter one or more (separated by spaces) domain names to search host if incomplete domain names will be used. Its optional.
PPP configuration
You can enter modem connection configuration parameters in this window:
- Config name - config name (used in existing configuration selection menu).
- Phone number - phone number to dial (eg. 0w202122 for TPSA access modems).
- Username - username to send to remote server
- Password - password to send to remote server
- Nameserver IP(s) - enter one or more (separated by spaces) name servers IP addresses here. Can be omitted, but then domain names couldnt be used.
- Default domain(s) - you can enter one or more (separated by spaces) domain names to search host if incomplete domain names will be used. Its optional.
Because of permanent configuration that is kept on the floppy you should remember to:
- dont write protect the floppy
- dont remove the floppy from the drive (at least during network configuration)
Enhancements:
- bugfixes in netconf reuse code
- disk partitions automounting, swap partitions autoactivating
- automatic swap file creation
- extended support for NFS mountable /usr
- PS/2 mouse support
- new startup logo

LiveLAMP is a bootable (i.e Live) CD that turns a spare computer in the classrom into a Linux development server for students to practice and publish programming exercises in over a dozen computer languages.

As the name suggests, the primary emphasis is on core technologies which underpin the LAMP platform: Linux + Apache + MySQL + PHP.

With the LiveLAMP project, OSV aims to do for Linux application and database servers what Knoppix has done for desktops. LiveLAMP can turn any PC into an instant server capable of supporting up to 1,000 users.

Besides Linux, Apache, MySQL and PHP, technologies included are Python, Perl, Ruby, PostgreSQL, C++, C, Pascal, Fortran, CVS, Apache, Lex/Yacc, text editing, HTML, JavaScript, CSS, XML and much more.

LiveLAMP will fully integrate with your existing Windows, Apple or Linux network and workstations. To start the installation process takes only a few minutes. You do not need any previous experience with Linux or web servers.

Program Guard allows the user of a Linux workstation to specify which application programs that are allowed TCP/IP connections to the Internet (Internet addresses are defined as any IP address not in the range of 10.0.0.0/24 or 192.168.0.0/16).

The application program names can be specified by listing them in a file (Static Mode) by querying the user (Query Mode). In Query Mode, when a program that is unknown to Program Guard attempts to access an Internet IP address, Program Guard displays the Program Guard Dialog Box.

In addition to providing connection information, this dialog box gives the workstation user the option of allowing the program to access the Internet or to be blocked from accessing the Internet. This can be done either for the current instance of the program or for this and all future instances of the program (Make Persistent checkbox).

Currently, the program names that are allowed or denied Internet access apply to all users of the workstation rather than on a per user basis. For example, if Program Guard is running in Query Mode and user A invokes a program previously blocked from Internet access by user B, the program will be blocked from Internet access for User A as well.

Connections blocked by Program Guard are logged to the Program Guard log file pgrd.log. It is located in the /var/log/pgrd directory. If desired, Program Guard can be configured to log all Internet connection attempts rather than just those that have been blocked.

Program Guard was tested on Fedora Core 1 and Fedora Core 3 on single processor 32 bit X86 Intel processors. It has not been tested on other distributions or on multi-processor machines. While it works on Fedora Core 1, it will not build on a standard Linux 2.4.x kernel due to task_struct definitions that were not made until Linux 2.6. If there is enough interest, a version that runs under a standard Linux 2.4 kernel may be made available.

To run in Query Mode, Gnome 2.x and Glade 2.x are required. There are no prerequisites for Static Mode.

Installation:

Program Guard consists of three components: a kernel module; a daemon; and a Gnome GUI user interface component. All files needed to build the components are in the pgrd.tgz file. An installation shell script install-pgrd is provided for Fedora distributions.

It will build/install (or remove) the kernel module and daemon as well as configure them to be started automatically when the system is booted. To invoke it, type install-pgrd < install | remove >. This script may or may not be useable as is for other Linux distributions.

If you modify the install script, please note that the module, daemon and various support files must be installed in the /opt/pgrd directory for Program Guard to work properly (this is already handled when using the install script as provided). To run in Query Mode, each user must be configured by invoking the install-pgrd_user < username > script. And by going to the Preferences->More Preferences->Sessions selection in the Fedora Main Menu and adding pgrdgui to the Startup Programs tab.

Program Guard will be started the next time the machine is rebooted. If you do not wish to reboot, you may start Program Guard manually as described below in Manual Starting And Stopping. Note: If starting manually and using Query Mode, once the daemon and kernel module are started, make sure that you log out and log back in.

StartCom Linux is based on the Red Hat AS source code.
Specially designed for the demanding home user, the MultiMedia Edition lets you easily communicate with your friends and family members over the Internet, browse the news or watching the latest DVD movie you just bought.
Listen to your loved Music while you check your email or play some funny game while you burn a CD, everything is easily accessible from your desktop by a click on your mouse button.
System configuration and adjustments of your preferences never have been so simple, thanks to the integrated configuration tools.
Enhancements:
- StartCom has released its new Multimedia Edition, ML-5.0.5, code named Kessem. Its probably one of the largest and most complete Linux distributions ever released to the public. Release ML-5.0.5, offers many out-of-the-box capabilities, never bundled with an operating system before. Designed as a multimedia workstation with music studio and advanced video editing applications, it also provides the desktop user with the most applications for day to day use.

Lineox Enterprise Linux distribution is based on source RPM packages from which Red Hat Enterprise Linux is compiled. Lineox Enterprise Linux contains all programs included in various Red Hat Enterprise Linux variations (Advanced Server (AS), Entry/Mid Server (ES), and Workstation (WS)).
It also contains programs included in separately sold Red Hat Cluster Suite and Red Hat Developer Suite. Lineox has removed and replaced all files of Red Hat Enterprise Linux which have restrictive copyright by Red Hat, Inc. Lineox has also tried to remove all user-visible references to Red Hat in Lineox Enterprise Linux.
The most notable difference between Lineox Enterprise Linux and Red Hat Enterprise Linux is the support options provided by Red Hat, Inc. Lineox, Inc. does not provide any support for Lineox Enterprise Linux with the base product.
Lineox, Inc. however plans to provide binary package updates for Lineox Enterprise Linux as long as Red Hat, Inc. provides updates for Red Hat Enterprise Linux in source package format.
Lineox has an automated system running on a cluster which builds new binary rpm packages as soon as new source code is available. New rpm packages are usually available in less than 12 hours after source code release.
After that Lineox builds Always Current Lineox Enterprise Linux disks automatically, but because of the time it takes to transfer the disk images to our web server, they are available from 2 to 12 hours after we release new packages.
Isnt Always Current Lineox Enterprise Linux untested or unreliable if it is released so often? Not really. We dont rebuild the installation environment, we just replace the installable packages with new ones.
You can even use same boot floppies or other boot media created for Lineox Enterprise Linux 4.0 to boot Always Current series Lineox Enterprise Linux. So Always Current Lineox Enterprise Linux is as tested and reliable as a system installed from "base release" and updated later. The only difference really is the work and time saved and the higher security right from the start.
Enhancements:
- Always Current Lineox Enterprise Linux 4.096 with Update 4 available. In the version 4.096 the installation environment is rebuilt, so it offers better hardware support during the installation. See the release notes for full information. The x86_64 release requires either AMD Opteron or Athlon64 CPU based computer. Some new Intel Xeon and Pentium IV processors with EM64T (Extended Memory 64 Technology) will also be able to run this version.

Debyer project takes as an input a file with atom positions and can output x-ray and neutron diffraction pattern, total scattering structure function, pair distribution function (PDF) and related functions (RDF, reduced PDF).

It can be run on any modern platform, from typical Linux or MS Windows workstation to large computer clusters. The parallel version uses MPI library.
