Cryproc is module for the Linux 2.6 kernel that allows user space programs to access the kernel's cryptographic functions. When loaded, the module creates a file called "cryproc" in the /proc filesystem. Applications can open this file read-write and instruct the kernel to perform some of the functions the CryptoAPI provides. A sample application, cryproc-tool, is provided.
Kerrighed is a Single System Image operating system (SSI) for clusters. It offers the view of a unique SMP machine on top of a cluster of standard PCs. The goals are high performance of applications, high availability of the cluster, efficient resource management, high customizability of the operating system, and ease of use. It is implemented as an extension to Linux operating system (a set of Linux modules and a small patch to the kernel).
DeTeWe ISDN device driver provides a Linux driver and userspace tools to support configuration and Internet access with DeTeWe (USB-VID:0x086c) ISDN hardware, such as soho-PBXs (Eumex x04/OpenCom/BeeTel/TA33 USB), phones (EuroMaster data), and DECT phones (Sinus 6x, BeeTel 40i).
Sysmask is a security package for Linux systems that can prevent arbitrary malicious codes from causing permanent damage. It protects the system against daemon exploits and user accounts against viruses and worms, whether known or unknown, without requiring the recompilation of existing software.
