asmutils is a set of miscellaneous utilities written in assembly language, targeted on embedded systems and small distributions (e.g. installation or rescue disks). It also contains a small libc and a crypto library. It is optimized for size, memory usage, and speed, and offers fairly good functionality. The project supports Linux and the BSD family. Unixware, Solaris, and AtheOS support is in beta stage. This package also aims to provide a portable development framework, and to encourage assembly programmers to write for Linux/Unix.
asNews is a simple news retrieving and parsing program which gets the news from the net and shows it in your desktop. It's currently able to fetch the news from Freshmeat, LinuxToday, Slashdot, Segfault, KDE, LinuxApps, BBC, CentralEurope, 7AM, LinuxDev, GeekNews, IceWalkers, AppWatch, Hotwired and Mozilla. It also has two GTK-based X11 interfaces: a very simple one used for easy integration with your Window Manager and a complete, comfortable GUI.
ASPseek is an Internet search engine, written in C++ using the STL library. It consists of an indexing robot, a search daemon, and a search frontend (CGI or Apache module). It can index as many as a few million URLs and search for words and phrases, use wildcards, and do a Boolean search. Search results can be limited to time period given, site, or Web space (set of sites) and sorted by relevance (PageRanks are used) or date. It is optimized for multiple sites (threaded index, async DNS lookups, grouping results by site, and Web spaces), but can be used for searching one site as well. It can work with multiple languages/encodings at once (including multi-byte encodings such as Chinese) due to optional Unicode storage mode. Other features include stopwords and ispell support, a charset and language guesser, HTML templates for search results, excerpts, and query words highlighting.
Astaro Portscan Detection is a netfilter target which will attempt to detect TCP and UDP port scans and log them to syslog. This target is based upon Solar Designer's scanlogd. It suppports mutliple levels of logging, custom prefixes for entries, weighted total port scan detection, and port scan temporal spread detection.
Asterisk is a hybrid TDM and packet voice PBX (Private Branch eXchange) and IVR platform with ACD functionality. It acts as middleware between the Internet (IAX, SIP, MGCP, Skinny, H.323), telephony channels (like Zaptel, T1, PRI, E1, FXO, FXS, VoIP, VoFR, ISDN, modems, Internet Phone Jack, etc.), and applications (like voice-mail, conferencing, directories, MP3 players, intercoms, etc.). It has many advanced features such as a codec translation API. The base distribution includes several channel backends, as well as applications. However, the beauty of Asterisk is its ability to be extended using its APIs, dynamic module loader, and AGI scripting interface. End users can even write their own applications that run on the system in C or any scripting language of their choice.
