Free live livecd software for linux

Olive is (yet another) GNU/Linux Live distribution. Olive LiveCD distirbution offers quite a good deal of new technologies, hardly witnessed ever before, as well as some of the more common pieces of software. Its size is approx. 110MiB, yet it allows a lot of software to be used.
Olives whole point is to display how easy to use Linux may be, yet without losing any of the features required for heavy-duty work. Its also supposed to show various unusual new technologies, not widely known or accepted.
Please note that Olive was, partially, built as graduation work at SPSST Panska. Once presented, a release built specifically for school will be available upon personal request.
Main features:
Media
Olive features MPlayer for playing of your favourite movies. It plays most MPEG, VOB, AVI, OGG/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, FLI, RM, NuppelVideo, Matroska files. You can also watch Theora, MPEG4 (DivX/XviD), Real Media, DVD, VideoCD, SVCD movies. MPlayer also supports various filters for better experience. Mencoder is bundled with MPlayer and it allows you to encode movies into virtually any of the formats mentioned above.
Although you can use MPlayer to play your music, theres also an application that was written just for that: Audacious. Audacious is a fork of Beep Media Player (now discontinued), which is in turn fork of the very famous XMMS. It supports various audio formats, including MPEG layer 1, 2, and 3, Ogg Vorbis, Ogg FLAC, Musepack, WAV files and Windows Media, as well as many sequenced formats including MIDI, and a host of different module formats. In addition, Audacious uses Winamp-like skins (and supports Winamp "classic" skins), to provide a familiar and friendly user interface.
You can of course view photos and pictures using GQview, an intuitive image browser. It can generate thumbnails of your pictures, its capable of reading EXIF metadata, has advanced image search function and much more.
Internet
The Internet is part of everyday life for all of us; was it not for the Internet, you wouldnt be able to read this webpage. Olive features Mozilla Firefox web browser, currently the most common web browser used on Linux. For browsing in console, ELinks is a must-have. There is also Sylpheed e-mail client, small, fast and incredibly useful.
These days, Instant Messaging is a common part of our lives. Therefore, Olive sports GAIM2 (beta2) multi-protocol instant messaging client, which is compatibile with protocols such as ICQ, MSN Messenger,Yahoo!, IRC, Jabber or Gadu-Gadu. There is also a client dedicated solely to Internet Relay Chat (IRC), which is X-Chat. As usually, there are console alternatives, which would be CenterICQ and irssi.
You can use Kismet to look for Wi-Fi hotspots. Basic utilities such as telnet or ssh client and server (Dropbear, used in various embedded systems) are not missing as well.
General work
You can perform some elementary office work in Olive as well. Although its obvious that you wont be doing most of your office work on Olive, its quite reasonable to believe it can come in handy. Therefore, Olive has AbiWord word processor to allow you to read and write documents, in various languages, in various characters, without any problem.
AbiWord can also handle various document formats, which includes Microsoft Word or WordPerfect documents. You can also export your documents into HTML for further processing or publication. You can also read Adobe PDF format using Evince, a Gnome/GTK2 document viewer whose PDF backend is based on the Poppler library, which is based on the well-known XPDF. Utilities that allow you export of PDF documents into eg. HTML are also included.
System control
Considering the differences in approach to configuration in various distributions, it may be often hard to configure several things at yet another distribution, such as the X server or preferences of software alternatives. Therefore, Olive features a trivial control panel, allowing any application to be merged in as a new panel. Although it still misses few more desired panels (most notable for network configuration), it already is quite useful for every day usage.
Eye candy
Good-looking environment always helps users to better orientate on the workplace, as well as consider the time they spend with the system more enjoyable. Transparency can be achieved using XComposite extension and xcompmgr + transset.
Though XGL and AIGLX were considered, the decision was made not to use them for their lack of testing and for the demand for support of as many platforms as possible. Please note that even XComposite may have its own issues with other software, most notably Enlightenment and MPlayer, and for this reason xcompmgr is not run by default.
Lightweight
If you consider the above features way too much for you and strive for something lighter, then you can use the FluxBox window manager. FluxBox was finetuned to look and feel as much as Enlightenment as possible, making the transition simple. There are also lightweight versions of some of the software, as mentioned above, such as irssi, CenterICQ or ELinks.
Enhancements:
- A significant bug was found in v0.1, causing ramdisk for people who have 1GiB of RAM or more broken. Please, upgrade to 0.2.

NeWBIE LiveCD is a NetBSD based distro geared towards the desktop user.
It includes software for Web browsing, chatting, multimedia, and document editing.
This acronym NeWBIE is pronounced just like the word "newbie" and stands for (Ne)tBSD (W)are (B)urned (I)n (E)conomy.
Newbie is a NetBSD (v. 3.0) live CD similar in spirit to the well-known FreeSBIE live CD. Newbie currently caters to the desktop-user (i.e. with applications for web browsing, chat, multimedia, document editing, etc) but will also serve as a core for creating a NetBSD version of Arudius (see below) - a network security auditing tool.
Why based on NetBSD? Because contrary to the popular opinion, NetBSD is not some obscure *BSD flavor that is only good for powering your toaster, but is a powerful, flexible and highly portable operating system.
In many aspects it is better than its more famous cousins. Did you know that NetBSD recently broke the speed record for network data transfer? And what about speed and scalability?
Enhancements:
- This release cleans up the boot process and adds a GUI tool for easy setup of the modem/DSL connection.
- More productivity tools are included (e.g. a file manager, spreadsheet, Samba, wireless AP detection, sniffer, network analysis, etc.).

Zenwalk Linux (formerly Minislack) is a Slackware-based Linux distribution with focus on Internet applications, multimedia and programming tools.
ZenLive Linux LiveCD is a complete system with software for Internet browsing, mail, chat, multimedia and office, as well as for programming in C, Perl, Python and Ruby.
The main objectives of Zenwalk Linux are to be simple and fast, provide one application per task, be a complete development and desktop environment and to be small enough to fit on a 400MB ISO image.
Enhancements:
- ZenLive 4.2 is based on Zenwalk Linux version 4.2 and compliments the speed and stability youve come to expect from Zenwalk. Some of the new features include Zenpanel which is Zenwalks new system configuration panel that makes customizing your Linux system easy. Desktop enhancements include a new panel layout and RSS feed reader that were added to Xfce among other nice enhancements, such as the original Tango-derived icon theme. Howl has been replaced with the more modern and supported Avahi Zeroconf subsystem. Fam has been replaced with Gamin resulting in noticeable speed increases to file and directory monitoring.

Etoile Live CD is a Linux distribution based on the popular Ubuntu Linux.

This is the 0.2 pre-release that we worked on at the Fosdem 2007. Theres still quite a lot of problems on it (check the bugtracker), so we expect the final 0.2 release in about a month. In the meantime, feel free to download the iso and play with it -- and reports any bugs that are not already in the bugtracker !"

The Real-Time Application Interface is a hard real-time extension to the Linux kernel, contributed in accordance with the Free Software guidelines.
It provides the features of an industrial-grade RTOS, seamlessly accessible from the powerful and sophisticated GNU/Linux environment.
The bootable CD-ROM provided on this website allows you to determine whether your systems hardware is capable of being used as a hard real-time system.
Furthermore, this website provides information about the real-time performance of various systems, which might help you when buying hardware for building hard real-time systems.
The LiveCD is based on RTAI (Realtime Application Interface) and provides easy-to-use menus that guide users through running the test suite and submitting the results and system configuration information to an Internet database.
Enhancements:
- Fixed issue where the per-loop max and min latency were stored in the database instead of the overall max and min latency... Added support for Gigabit Ethernet (requested by Phil Nitschke)
- Reduced ISO size to 8MB

This is a fedora core 3 based Livecd with KDE 3.3.1, Gnome 2.8, OpenOffice, Fire- and Thunderbird and a lot of other tools.

FreeMED is a Web-based medical records (EMR) and patient management system with a printing system, patient scheduling, an HL7 interface, a billing system, XML-RPC Web services, and many other features.

It has an extensible modular architecture, allowing it to be customized based on individual practices without having to rewrite core components of the system. It is HIPAA compliant.

FreeMED LiveCD 0.1 is based on the Kubuntu 5.04 (Hoary) Live CD.

NetBSD LiveCD is a bootable ISO image contains NetBSD 3.99.7 and allows you to boot NetBSD/i386 -current without having to install to a hard disk.

The LiveCD was initially intended to be a rescue cdrom, but is now capable of much more.

The default desktop environment is KDE. But there is another window manager available: pekwm.

The LiveCD will automatically try to obtain an IP address via DHCP. If that fails, you must manually configure your network settings. For information on this, please see the NetBSD Guide.

There are two users: root and user. The password for both is NetBSD. If you are logged in as user, you can use sudo(8).
