Two-FritzCards-Howto [lokale Kopie]: It's possible to use two Fritz cards simultaneously in one computer. 2 Fritz/PCI Cards are about 3 times cheaper than an AVM C2 Card and both have the same number of B-Channels, so this is a good way to save money. The kernel driver for Fritz!Cards can easily handle 2 or more of them. When doing CAPI, however, you need the AVM Drivers, which need some tweaking before they work in "dual mode". But this way it's possible to run multiple ISDN cards...

Scan items and plugins are frequently updated and can be automatically updated (if desired).

ddrescue: ddrescue copies data from one file or block device (hard disk, cdrom, etc) to another, trying hard to rescue data in case of read errors. ddrescue does not truncate the output file if not asked to. So, everytime you run it on the same output file, it tries to fill in the gaps. If you have two or more copies of a damaged file, cdrom, etc, you will probably obtain a complete and error-free file. There is also a bad blocks file feature of ddrescue.

SPF (Sender Policy Framework): SPF fights email address forgery and makes it easier to identify spams, worms, and viruses. Domain owners identify sending mail servers in DNS. SMTP receivers verify the envelope sender address against this information, and can distinguish legitimate mail from spam before any message data is transmitted.

A Stackable Unification File System: This project builds a stackable unification file system (unionfs), which can appear to merge the contents of several directories (branches), while keeping their physical content separate. Unionfs is useful for unified source tree management, merged contents of split CD-ROM, merged separate software package directories, data grids, and more. Unionfs allows any mix of read-only and read-write branches, as well as insertion and deletion of branches anywhere in the fan-out. To maintain unix semantics, Unionfs handles elimination of duplicates, partial-error conditions, and more. Unionfs is part of the larger FiST project.

FiST: Stackable File System Language and Templates: le System development is very difficult and time consuming. Even small changes to existing file systems require deep understanding of kernel internals, making the barrier to entry for new developers high. Moreover, porting file system code from one operating system to another is almost as difficult as the first port. Past proposals to provide extensible (stackable) file system interfaces would have simplified the development of new file systems. These proposals, however, advocated massive changes to existing operating system interfaces and existing file systems; operating system vendors and maintainers resist making any large changes to their kernels because of stability and performance concerns. As a result, file system development is still a difficult, long, and non-portable process. The FiST (File System Translator) system combines two methods to solve the above problems in a novel way: a set of stackable file system templates for each operating system, and a high-level language that can describe stackable file systems in a cross-platform portable fashion. Using FiST, stackable file systems need only be described once. FiST's code generation tool, fistgen, compiles a single file system description into loadable kernel modules for several operating systems (currently Solaris, Linux, and FreeBSD). The project demonstrates that with FiST, code size and development time are reduced significantly, while imposing a small performance overhead of only 1-2%. These benefits are achieved, as well as portability, without changing existing operating systems or file system.

ZEDAT UPS Daemon (ZUPS): ZUPS allows for monitoring the state of one or more UPS devices using SNMP and executing user-specified commands in case of power outage, such as e-mail or pager notifications and controlled remote host shutdowns. If the monitored UPS devices are running on battery, the shutdown commands are executed for an arbitrary number of remote hosts, optionally with some delay specified for each host. Additionally, ZUPS can be configured to ignore these delays and run the specified commands immediately if the UPS devices are running out of battery power. Custom plugins can easily be added in order to perform arbitrary other checks.

Network UPS Tools (NUT): Network UPS Tools (NUT) provide reliable monitoring of UPS hardware and ensure safe shutdowns of the systems which are connected.
