Lonix is a console-based full Linux system which runs from a live CD. It includes a lot of useful utilities for students and developers, along with some servers like Apache, Proftpd, sendmail, and sshd (all pre-configured). It can also be used as a partition tool (featuring fdisk, parted, and partimage) or as a rescue CD.
Storix Backup Administrator (SBAdmin) provides both an intuitive graphical user interface and command line options for performing backups of a standalone system, or managing backups of all Linux and AIX systems on a network. In addition to backing up data onto a network server, tape, or disk device, it can reinstall a complete system from scratch, clone or migrate systems, manage volumes and RAID devices, and restore data in any configuration you choose. It features easily accessible documentation.
Cool Linux CD is a bootable CD that contains a a live Linux distribution based on RedHat 7.3. It also includes the XFS filesystem, devfs, IceWM, QVWM, ROX-filer, OpenOffice.org, Opera, Mozilla, Sylpheed, Pan, Licq, X-chat, GFTP, ppp-redialer, xmms, xine, mplayer, gqview, LinNeighborhood, IPTraffic, VMWare, and more.
Simple Rescue CD is a small Linux rescue CD, suitable for booting systems that have become unbootable due to filesystem corruption or other problems. It lies somewhere between minimalist boot floppies and large full-featured rescue systems, and as such is suitable for when space is tight, such as on business card CDs.
flexbackup is a configurable and easy to use Perl-based backup tool, that can backup local files as well as remote machines (using ssh). It allows the backup itself to be made with afio, cpio, tar, dump, star, or pax. It can work with tape drives, on-disk archive files, or on-disk directory trees.
Vexira Antivirus is virus defense system. It can identify which files may contain malicious code requiring further investigation, which greatly increases virus scanning speed. It features the ability to scan files automatically as they are accessed, configurable path protection, email notification, blocking of access to infected files, options to repair, rename, or delete infected files, automated Internet updating, virus scan archives (.zip, .rar, gz, .tar, etc.), a commandline scanner, scalable concurrent scanning, heuristic detection of new macro viruses, and low system resource requirements.
KNOPPIX is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI devices, and other peripherals. It can be used as a Linux demo, educational CD, rescue system, etc. It is not necessary to install anything on a hard disk due to on-the-fly decompression.
skill sends signals to processes given any combination of user names, ttys, commands, and pids. snice changes the priority of processes (given the same). They are similar to kill(1) and renice(8), but the commandline is order-independent. There are also verbose, search, and interactive modes of operation.
chpox provides transparent checkpointing and restarting of processes on Linux clusters. It was originally designed for recovering tasks that have a long execution time (i.e. numerical simulations) in case of system crashes, power failures, etc. It may work with openMosix, is SMP safe, does not require program recompiling/relinking, and supports virtual memory, regular open files, pipes, Unix domain sockets, current directory, and child processes.
