ZMailer is an internet message transfer agent. It is intended for gateways or mail servers or other large site environments that have extreme demands on the abilities of the mailer. It was motivated by the problems of the Sendmail design in such situations. It is intended and designed as a multi-protocol mailer. The only protocol supported in this distribution is RFC822 (and variations).
Dirvish creates a backup image of a directory tree using rsync. If there is already an older backup image, files which have not changed will be shared (hard-linked) between the two backups to save disk space. Where files have partially changed, rsync sends only the differences over the network. Each backup image is a complete copy of the original directory and can be used independently for restores, or deleted without affecting the other images.
QEMU is a fast processor emulator. Using dynamic translation it achieves a reasonable speed while being easy to port to new host CPUs. In its user mode emulation mode, it can launch Linux processes compiled for one CPU on another CPU. Linux system calls are converted because of endianness and 32/64 bit mismatches. In its full system emulation mode, it emulates a full system, including a processor and various peripherials.
NetInstaller lets you create setup wizards for Web applications written in PHP. Users only have to upload two files; everything else will be decompressed online on the server, created, and configured. This eliminates the need to perform tedious permission changes (with chmod) or to upload of hundred of files in order to install a PHP application onto a Web server.
Libsmbios is a cross-platform library intended to be used to obtain common information available in a BIOS. Major features include the ability to update the BIOS on Dell systems (in conjunction with the Dell RBU Linux kernel driver), programmatic access to information in SMBIOS tables, and the ability to obtain Dell system-specific information such as the Dell System ID number, service tag, and asset tag. Future plans include APIs for $PIR and mptable mapping. There is a C API for some of the more commonly used functions, and example binaries to show off most of the facilities.
firmware-tools is an architecture that utilizes native Linux packaging formats (.rpm and .deb) and native Linux change management frameworks (yum, apt, etc) for delivering and installing system firmware. This architecture is OS distribution, hardware vendor, device, and change management system agnostic.
