iSCSI Linux Initiator Driver is a kernel module for use with linux-2.4.x. This module provides client-side support for iSCSI. iSCSI is an IETF draft desribing SCSI encapsulation over TCP/IP. This release was written to version 3 of the draft. The drive is architected as a lower half adapter driver. Do not use SCSI devices with important data on the target side.
grsecurity is a complete security system for Linux 2.4 and 2.6 that implements a detection/prevention/containment strategy. It prevents most forms of address space modification, confines programs via its Role-Based Access Control system, hardens syscalls, provides full-featured auditing, and implements many of the OpenBSD randomness features. It was written for performance, ease-of-use, and security. The RBAC system has an intelligent learning mode that can generate least privilege policies for the entire system with no configuration. All of grsecurity supports a feature that logs the IP of the attacker that causes an alert or audit.
kchuid is an experimental Linux kernel module that allows you to change the UID/GID/CAPS of a running process (by PID). Think of it as providing a setuid() system call that also has a pid_t argument. It's the first step in a full authentication system, and further, a full Unixish system devoid of setuid binaries/scripts.
UDI, the Uniform Driver Interface, is a well-documented interface between a driver module and the executing OS. It provides source portability across OSes and binary portability within a processor ABI. It also provides modern driver features like instance independence, high scalability, and physical location transparency. The Reference Source provides an initial implementation of UDI for Linux, SCO UnixWare, SCO OpenServer, and other OSes.
WANPIPE S-series is a family of intelligent multi-protocol WAN and ADSL adapters that support data transfer rates up to 8Mbps. All WAN protocols supported by WANPIPE are implemented in firmware and run on the card. An advantage of an intelligent adapter is that it offloads the system CPU and improves stability. By adding a Sangoma WAN/ADSL component to the Linux kernel, one can create a powerful multi-T1/ADSL router/firewall with proven reliability of Linux. Sangoma S-series cards support an optional on board T1/E1 CSU/DSU that eliminates all external components of a traditional routing solution: i.e. T1/E1 line can be directly connected to the card. WANPIPE supports the following protocols, ATM, ADSL, Frame Relay, PPP, MULTILINK PPP, CHDLC, X25(API), BitStreaming (API), BiSync(API), and SDLC(API). Furthermore, WANPIPE supports custom API development such as: Credit card verification, Voice-over IP, Satellite Comm. All device drivers are part of the standard Linux Kernel distribution.
Linux is a clone of the Unix kernel, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. It has all the features you would expect in a modern fully-fledged Unix kernel, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and TCP/IP networking.
