GeeXboX is a standalone media player Linux distribution, similar to MoviX. It's a small bootable CD that allows you to play your favorite video (DivX, XviD, H.264, MPEG 1/2, VCD, DVD, OggMedia, Windows Media, RealMedia, etc.) and audio (MP3, Audio CD, Ogg Vorbis, FLAC, MPC, etc.) files. It also supports networking, and is able to play media from Windows/Samba share, NFS, UPnP A/V Media Servers, RTP/RTSP servers, or SHOUTcast. It supports TV-out, TV tuners, DVB cards, and WiFi cards. It is based on MPlayer, and can be used on any x86, x86_64, or PowerPC computer. It's easy to modify the source to build your own GeeXboX or use an alternative boot method.
DirectFB is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, an integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer device. It is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware.
BitRock InstallBuilder allows you to create easy-to-use multiplatform installers for Linux (x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.
uClibc (µClibc) is a C library for developing embedded Linux systems. It is much smaller then the GNU C Library, but nearly all applications supported by glibc also work perfectly with uClibc. Porting applications from glibc to uClibc typically involves just recompiling the source code. uClibc even supports shared libraries and threading. It currently runs on standard Linux and MMU-less Linux (also known as µClinux) systems with support for ARM, i386, h8300, m68k, MIPS, mipsel, PowerPC, SH, SPARC, and v850 processors.
Cobbler is a network installation and update server. It can be used to automatically set up PXE, install virtual guests, manage answer files, and reinstall existing Linux machines. Advanced features include importing distributions from DVDs and rsync mirrors, kickstart templating, integrated yum mirroring (integrated with the installer to make updates available at install time), creation of netboot ISOs, and built-in DHCP/DNS Management. Tools such as "cobbler triggers", a Python API, and an XMLRPC API allow integration with cobbler with the rest of your datacenter environment or other systems management applications. There is also a Web interface to simplify management of the install server. Cobbler supports RHEL 4+, Fedora, and derivative distributions, and is also able to install other popular distributions.
Compact Flash Linux Project is a Linux distribution designed to run on a compact flash card in read-only mode. It is as small as possible, and currently needs around 14 MB. It includes OpenSSH, quagga, iptables, hostap, madwifi, wireless-tools, pppoe, tcpdump, bridge-utils, and more.
wrt54g-linux is a mini-distribution for the Linksys wrt54g 802.11b/g access point and router. It includes basic tools such as sh, syslog, telnetd, httpd (with cgi-bin support), vi, snort, mount, insmod, rmmod, top, grep, find, nfs modules, etc. The installation script runs in about 20 seconds and installs strictly to the RAM disk. If you mess anything up, simply reset the box. After installing the distribution you'll be able to telnet in, add Web pages, change iptable rules, change routing, configure snort, etc.
LPAR2RRD makes historical, future trends and nearly "realtime" CPU utilization graphs of LPARs and shared CPU usage of IBM Power servers. It collects complete physical and logical configuration of all servers/LPARs. It is agent-less (it gets everything from the HMC/SDMC or IVM). It supports all kinds of logical partitions (AIX/AS400/Linux/VIOS).
JayOS is a live CD Linux distribution intended for use as a more secure mobile environment. It uses GNU makefiles and Bash shell scripts to automate the building of a complete Linux distribution from source. The result is a turnkey solution for creating a compact, highly-customizable OS. JayOS includes many standard network security and filesystem tools, a full-blown development environment, and many programming tools and libraries including GCC, GDB, DDD, Perl, GTK+, Tcl/Tk, PHP, Ruby, Python, Qt, and Glade. It runs well on commodity hardware, and can be configured to run entirely from memory. In-RAM filesystem encryption with plausible deniability provides a more secure mobile workstation. It is based on Linux From Scratch.
WISP-Dist is a modular embedded Linux distribution for wireless routers, but can be used for other purposes as well. The entire system fits in 8 MB flash/16 MB RAM. Highlights include an easy-to-use menu interface, commandline access, an Access Point mode (on selected cards), OSPF/RIPv2, bandwidth shaping, NAT, Layer 3 (proxy arp) bridging, and other goodies. The goal is to create an open, customizable, and easy-to-use solution for wireless routers.
