NASLite is a Network Attached Storage (NAS) server operating system designed to transform a basic computer into a dedicated file server. Utilizing highly optimized versions of Samba, uCLibc, BusyBox, and various other Linux tools, it provides SMB/CIFS, FTP, or NFS filesystem support. It accommodates multiple client OSes: Windows, Mac OS X, and Linux. NASLite offers SMART disk monitoring and large file support, and is incredibly easy to install and administer.
ipt_pkd is an iptables extension implementing port knock detection with SPA (single packet authorization). This project provides 3 parts: the kernel module ipt_pkd, the iptables user space module libipt_pkd.so, and a user space client knock program. For the knock packet, it uses a UDP packet sent to a random port that contains a SHA-256 of a timestamp, small header, random bytes, and a shared key. ipt_pkd checks the time window of the packet and does the SHA-256 to verify the packet. The shared key is never sent.
WinDriver automates and simplifies the development of user-mode Linux device drivers for PCI, CardBus, ISA, PMC, PCI-X, PCI-EXPRESS, and CompactPCI as well as USB 1.1/2.0. No internal OS knowledge or kernel level programming is required. It supports kernel 2.0.31 and above, including embedded Linux, x86 and PowerPC processors, and any 32-bit development environment supporting C or Delphi. Applications are source code compatible across Windows 98/Me/NT/2000/XP/XP Embedded/Server 2003/CE, Linux, Solaris, and VxWorks.
Linux, in the tradition of UNIX-like operating systems, implements file system permissions using a rather coarse scheme. While this is sufficient for a surprisingly large set of applications, it is too inflexible for many other scenarios. For that reason, all the major commercial UNIX operating systems have extended this simple scheme in one way or the other. This is an effort to implement POSIX-like Access Control Lists for Linux. Access Control Lists are built on top of Extended Attributes, which can also be used to associate other pieces of information with files such as Filesystem Capabilities, or user data like mime type and search keywords.
Grml is a live system (live CD) based on Debian. It includes a collection of GNU/Linux software especially for system administrators and users of texttools. It provides automatic hardware detection and its default shell is the zsh. You can use it e.g. as a rescue system, for analyzing systems/networks, or as a working environment. It is not necessary to install anything to a hard disk; you don't even need a hard disk to run it. Due to on-the-fly decompression, it includes more than 2 GB of software and documentation on the CD.
ctunnel is a program for tunneling and proxying TCP or UDP connections via a cryptographic tunnel. ctunnel can be used to secure any existing TCP or UDP based protocol, such as HTTP, Telnet, FTP, RSH, MySQL, VNC, DNS, XDMCP, NFS, etc. You can also chain or bounce connections to any number of intermediary hosts.
KernelDriver automates your Windows 2000/NT, Windows Me/98/95 and Linux device driver development by providing you with powerful tools for hardware debugging, driver code generation, and driver debugging. KernelDriver supports PCI / USB / ISA and EISA drivers. KernelDriver for Windows and Linux includes the powerful Driver Wizard. Using the Driver Wizard you can graphically debug your hardware by "peeking" and "poking" at it without writing a single line of code. After your hardware is diagnosed, use the Driver Wizard to generate a complete kernel mode device driver which will drive your hardware.
