Active Spam Killer Active Spam Killer (ASK) confirms the sender's email address before actual delivery takes place. A "confirmation message" is automatically sent to all "unknown" users. Once the sender replies to that message (a simple reply will do), all future emails from that person are delivered immediately. You can also specify (regexp) addresses to be immediately accepted, rejected (with a nastygram) or ignored. The package also includes a utility to scan your old mailboxes and generate a list of emails to be accepted automatically.

Aircrack 'aircrack' is a set of tools for auditing wirelessnetworks. It consists of: airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), and airdecap (decrypts WEP/WPA capture files).

Apt-torrent 'apt-torrent' contains an apt to the BitTorrent gateway. It lets you fetch packages through the BitTorrent protocol

ArgusEye ArgusEye is a GUI for some of the features of Argus. Argus is a powerful suite of tools for transaction-based network auditing. ArgusEye aims at supporting daily work with Argus by providing a graphical user interface.

Aria Aria is a download tool similar to Reget or GetRight. It downloads files from the Internet via HTTP or FTP. The transfer can be paused, resumed, queued, and saved. You can paste URLs from the clipboard, pasting as many as you want at a time. It has a friendly GTK-based GUI and useful log consoles. It supports URL list import, CRC checking, an HTTP proxy server, HTTP recursive downloads, defining specific file retrieval procedures for particular servers, and cut-and-paste.

Aria2 aria2 is a utility for downloading files. It has completely new design concept from its predecessor, Aria, and is written from scratch. aria2 has a segmented downloading engine in its core. It can download one file from multiple URLs or multiple connections from one URL. This results in very high speed downloading, much faster than ordinary browsers. This engine in was implemented in a single-thread model. The architecture is clean and easy to extend. aria2 currently supports HTTP, FTP, and BitTorrent. It also supports Metalink version 3.0.

Authfail 'authfail' is a tool for adding IP addresses to an ACL when entities from those addresses attempt to log into a system, but cause authentication failures in auth.log. It reads data from auth.log in real time and adds the IP into netfilter with a DROP/REJECT policy.

AutoScan 'AutoScan' is an application designed to explore and manage your network. Entire subnets can be scanned simultaneously without human intervention. It features OS detection, automatic network discovery, a port scanner, a Samba share browser, and the ability to save the network state.

Autossh Autossh is a program to monitor and automatically reestablish SSH connections. It is similar to rstunnel (Reliable SSH Tunnel), but is easier to set up and use, especially for connections to multiple hosts. The program monitors connections by using a loop of port forwardings, and will back off on the rate of connection attempts when experiencing rapid failures (such as connection refused).

BIRD BIRD is a dynamic routing daemon for UNIX-like systems. It should support all routing protocols used in the contemporary Internet, such as BGP, OSPF, RIP, and their IPv6 variants (except for OSPFv3 which is still under development). It also has a very flexible configuration mechanism, and a route filtering language.

BannerKiller BannerKiller is a very simple HTTP proxy that lets you filter pages by forbiding pages whose URLs match some pattern. It can be used for censorship or to filter ads, and is particularly valuable for people with slow connections who normally have to wait for banner ads to download before they can view a page. The software is no longer currently being developed; the authors suggests the program SwiftSurf in place of bannerkiller.

BasE91 'basE91' is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% (versus 33% for base64) and can range down to 14%, which typically occurs on 0-byte blocks. This makes basE91 very useful for transferring larger files over binary insecure connections like e-mail or terminal lines.

Bigboos Bigboos is a network monitoring system that pools devices based on configuration. It is designed to allow mid-sized ISPs to monitor their network and central offices whose branch offices are connected on T1 or E1 lines to monitor their clients and branches. It is based on ICMP and SNMP. A small customer database manager is included. It has the capability to generate and manage trouble tickets, provides the current status about devices being monitored, and generates downtime reports.

BioMail BioMail automates searching for recent scientific papers in the PubMed Medline database, and can periodically run a customized Medline search and send all recent matching articles to the user's e-mail address. You can save search patterns: no more remembering which search was good and which wasn't. It is intended for medical researchers, biologists, and anyone who wants to know the latest information about a disease or a biological phenomenon. It is also useful for users who have email address but slow or sporadic Web access; they can set up searches and have them emailed to an address instead of having to surf the Web themselves for the information.

Bitflu Bitfu is a BitTorrent client designed to run non-stop as a daemon. It does not provide a graphical interface, but offers a telnet interface and can handle multiple torrent downloads.
