py-kqueue (aka PyKQueue) is a Python module that interfaces to the kqueue(2) and kevent(2) system calls. kqueue(2) and kevent(2) implements an event-driven notification system, intended as a replacement for select(2) and poll(2), which require lengthy preparation and bookkeeping to use. With kevent(2), a list of file descriptors or other object to monitor is passed in once, and the system returns a notification when the object triggers a filter, such as 'ready to read data' for file descriptors. See the man pages for details. This Python module provides a C module and supporting Python script to use these functions in a object-oriented manner.

Nast is a packet sniffer and a LAN analyzer based on Libnet and Libpcap. As analyzer tool, it has many features like: * Build LAN hosts list * Follow a TCP-DATA stream * Find LAN internet gateways * Discorver promiscous nodes * Reset an established connection * Perform a single half-open portscanner * Perform a multi half-open portscanner * Find link type (hub or switch) * Catch daemon banner of LAN nodes * Control arp answers to discover possible arp-spoofings * Byte couting with an optional filter * Write reports logging It also provides a ncurses menu.

pdnsd is a proxy dns server with permanent caching (the cache contents are written to hard disk on exit) that is designed to cope with unreachable or down dns servers (for example in dial-in networking). pdnsd can be used with applications that do dns lookups, eg on startup, and can't be configured to change that behavior, to prevent the often minute-long hangs (or even crashes) that result from stalled dns queries. Some Netscape Navigator versions for Unix, for example, expose this behavior. pdnsd is configurable via a file and supports run-time configuration using the program pdnsd-ctl that comes with pdnsd. This allows you to set the status flags of servers that pdnsd knows (to influence which servers pdnsd will query), and the addition, deletion and invalidation of DNS records in pdnsd's cache. Parallel name server queries are supported. This is a technique that allows querying several servers at the same time so that very slow or unavailable servers will not block the answer for one timeout interval. Since version 1.0.0, pdnsd has full IPv6 support.

OpenDMARC is an open source implementation of Domain-based Message Authentication, Reporting & Conformance, or DMARC. It builds on the successes of technologies such as DomainKeys Identified Mail (DKIM) and the Sender Policy Framework (SPF) to create an infrastructure that enforces policy on domain names that are visible to end users, and creates a feedback framework for identifying and tracking fraudulent use of domain names in email. It includes a library for handling DMARC record parsing, a database schema and tools for aggregating and processing transaction history to produce DMARC reports, and a filter that ties it all together with an MTA using the milter protocol.

Mail::Freshmeat is a parser for the daily newsletters from freshmeat.net. See <http://www.new.ox.ac.uk/~adam/computing/fmscore/> for what may be the only sensible application of this module. (Quick summary: fmscore is a Perl5 program which uses Mail::Freshmeat to parse freshmeat daily e-mail newsletters, and then rank them by interest according to highly flexible user-supplied ranking rules. Articles below a specified score will be removed from the output. fmscore is ideal for use as a procmail filter.)

maildrop is a replacement for your local mail delivery agent, similar to mail/procmail. - maildrop reads a mail message from standard input, then delivers the message to your mailbox. - maildrop will optionally read instructions from a file, which describes how to filter incoming mail. Instructions can be provided having mail delivered to alternate mailboxes, or forwarded somewhere else. Unlike procmail, maildrop uses a structured filtering language. - maildrop knows how to deliver mail to mbox-style mailboxes and maildirs. - maildrop is written in C++, and handles resources more efficiently. maildrop can be used with sendmail, qmail, and other MTAs.

The octave-forge package is the result of The GNU Octave Repositry project, which is intended to be a central location for custom scripts, functions and extensions for GNU Octave. contains the source for all the functions plus build and install scripts. This is ltfat. The Large Time/Frequency Analysis Toolbox (LTFAT) is a Matlab/Octave toolbox for working with time-frequency analysis, wavelets and signal processing. It is intended both as an educational and a computational tool. The toolbox provides a large number of linear transforms including Gabor and wavelet transforms along with routines for constructing windows (filter prototypes) and routines for manipulating coefficients.

flowd is a small, fast and secure NetFlow collector. It offers the following features: * Understands NetFlow protocol v.1, v.5, v.7 and v.9 (including IPv6 flows) * Supports both IPv4 and IPv6 transport of flows * Secure: flowd is privilege separated to limit the impact of any compromise * Supports filtering and tagging of flows, using a packet filter-like syntax * Stores recorded flow data in a compact binary format which supports run-time choice over which flow fields are stored * Ships with both Perl and Python interfaces for reading and parsing the on-disk record format * Is licensed under a liberal BSD-like license

Markdown is a text-to-HTML filter; it translates an easy-to-read and easy-to-write structured text format into HTML. Markdown's text format is most similar to that of plain text email, and supports features such as headers, *emphasis*, code blocks, blockquotes, and links. Markdown's syntax is designed not as a generic markup language, but specifically to serve as a front-end to (X)HTML. You can use span-level HTML tags anywhere in a Markdown document, and you can use block level HTML tags (like <div> and <table> as well).
