Skylable SX is a reliable, powerful, fully distributed cluster solution for your data storage needs. It can aggregate the disk space available on multiple servers and merge it into a single storage system. The cluster makes sure that your data is always replicated over multiple nodes (the exact number of copies is defined by the sysadmin) and synchronized. It has built-in support for deduplication, client-side encryption, on-the-fly compression, and much more.
Monkey HTTP Daemon is a very fast and lightweight Web server for Linux. It uses a hybrid networking model based on asynchronous calls (event-driven) and fixed threads, which makes it scalable and capable of attending thousands of clients per second. It provides a powerful API for C and is ideal for embedded devices, thanks to its small core and plugin architecture.
Postgrey is a Postfix policy server that implements greylisting. When a request for mail delivery is received by Postfix via SMTP, the triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first time that this triplet is seen, or if the triplet was first seen less than 10 minutes ago, then the mail gets rejected with a temporary error. Hopefully, spammers or viruses will not try again later, even though such behavior is required per RFC.
G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click'n'Clone" function. G4L supports file splitting if the local filesystem does not support writing files larger than 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
Univention Corporate Client (UCC) is a flexible and efficiently manageable operating system for PCs, notebooks, and thin clients in companies and institutions. The software contains a Linux-based desktop environment optimized for business use. It allows desktops to be adapted to hardware and intended applications. In addition, it can be managed conveniently and efficiently via a Web-based console. In comparison to other systems, it guarantees integrated administration procedures for users, clients, desktops, and permissions and effectively does away with the use of different, uncoordinated tools. It serves as a platform for access to remote desktop solutions and virtualized desktops as well as browser or terminal server-based applications.
FFmpeg is a tool for converting audio, video, and subtitles. It includes libavcodec, the leading open source codec library. It also includes libavformat (implementing muxers and demuxers), libswscale (for very fast video scaling), and libavfilter (an advanced video filter system supporting arbitrary filter graphs), and libavutil (a utility library intended to supplement libc). A simple multimedia player is included too. An experimental streaming server for live broadcasts is also included.
