AFD AFD is a program to automatically distribute files either locally or to remote hosts. The files are distributed by using FTP or SMTP, and can be sent in parallel and with priority. It provides a GUI to monitor and control the distribution and extensive logging of all activities.

APing APing is the advanced ping program written in Python from scratch that can execute four type of ICMP probes :

• echo request
• address mask request
• timestamp request
• and information request

You can also change the TOS value in packets, retrieve the UTC time from a valid timestamp reply packet, or to change the TTL, even to trace the sent packets to understand better what's going on.

Acct The GNU Accounting utilities `ac', `accton', `last', `lastcomm', and `sa' add login and process accounting support to GNU/Linux. "Login accounting" provides summaries of system resource usage based on connect time, and "process accounting" provides summaries based on the commands executed on the system.

AcpiTool AcpiTool is a Linux ACPI client. It's a small command line application, intended to be a replacement for the apm tool. The primary target audience are laptop users, since these people are most interested in things like battery status, thermal status and the ability to suspend (sleep mode). The program simply accesses the /proc/acpi or /sysfs entries to get or set ACPI values. A computer running a Linux kernel from the 2.4.x or 2.6.x series with ACPI enabled is needed. It also supports various extensions for Toshiba, Asus, and IBM Thinkpad laptops.

Adjtimex This program gives you raw access to the kernel time variables. For a machine connected to the Internet, or equipped with a precision oscillator or radio clock, the best way to keep the system clock correct is with xntpd. However, for a standalone intermittently connected machine, you may use adjtimex instead to at least correct for systematic drift. Adjtimex can optionally adjust the system clock using the CMOS clock as a reference, and can log times for long-term estimation of the drift rates.

Adtool 'adtool' is a *nix command line utility for Active Directory administration. Its features include user and group creation, deletion, modification, password setting, directory query, and search capabilities.

Afick 'afick' is a multi-platform file integrity checker. It works by first creating a database that represents a snapshot of the essential parts of your computer system. You then run the script to discover all modifications made since the snapshot was taken (i.e. files added, changed, or removed). It shows new, deleted and changed files (rights, owner, size, content).

Afick-Webmin This Webmin module facilitates Afick remote administration. It lets administrators to consult history and archives logs, change the Afick configuration, and run Afick.

Airhook Airhook is a reliable data delivery protocol, like TCP. Unlike TCP, Airhook gracefully handles intermittent, unreliable, or delayed networks. Other features include session recovery, queue control, and delivery status notification. Airhook is useful for keeping connections running over bad wireless networks (like CDPD), intermittent dial-up connections, and any other network that doesn't work very well. The implementation includes a TCP proxy (so you can use HTTP, SSH, etc.) and a protocol library for applications that want more control (real-time media delivery, games, etc).

Alarm Pinger Alarm Pinger (apinger) is a little tool which monitors various IP devices by simple ICMP echo requests. Unlike most Perl or shell script tools, it does not spawn processes or use much CPU time, and is ideal for when one wants continuous monitoring and fast response upon target failure. It supports both IPv4 and IPv6. Alarm Pinger is configurable via $sysconfdir/apinger.conf file. The configuration file contains definitions for alarms, targets and various parameters. It does need root privileges to start (to create raw sockets), but will drop them before sending or receiving any packets.

Alexis FTP (aftp) aftp is an FTP library and a background FTP tool. The aftp tool is a good example on how to use the library. You need FTP functionality in your software? Use the aftp library!

Alien 'alien' converts between the rpm, deb, Stampede slp, and Slackware tgz file formats. If you want to use a package from a distribution different from the one installed on your system, 'alien' will convert it to your preferred package format and install it. However, 'alien' should not be used to replace important system packages, like sysvinit, shared libraries, or other things that are essential for the functioning of your system. Many of these packages are set up differently by Debian and Red Hat, and packages from the different distributions cannot be used interchangably.

Alist Alist is a program that collects hardware and software information about systems and stores it in a database for users to browse and search via a Web interface. The program consists of three parts: a client portion that collects the information, a daemon that receives data sent from clients, and a CGI that displays and lets you search for information.

Am-utils The Berkeley Automounter, Amd, maintains a cache of mounted file systems, and lets users dynamically control which file system to mount with selectors. Selectors, which may be combined, allow decisions of the form "hostname is this," or "architecture is not that." Amd also supports numerous file system types, including NFS, UFS and the novel program file system. The combination of selectors and multiple file system types means that identical configuration files can be used on all machines. Amd will not hang if a remote server goes down, and can determine when a remote server has become inaccessible and mount replacement file systems when they become available.

Amanda AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup system that allows the administrator of a LAN to set up a single master backup server to back up multiple hosts to a single large capacity tape drive. AMANDA uses native dump and/or GNU tar facilities and can back up a large number of workstations running multiple versions of Unix. Recent versions also support SAMBA.

Analog It is fast, easy to install and run, very flexible, features multi-language support, produces attractive output, can be run directly or from a form interface, understands any logfile format, and works on any operating system. It can report in 36 languages.

Andatool 'andatool' displays in real time how often regular expressions match with the lines written to a logfile. This shows (for example) which firewall rules get triggered the most.

AntiDialer AntiDialer is a QT-based broadband dialer for Sify Broadband users in India. It has features comparable to the Sify Windows dialer, such as password saving and autologin. Now Sify users no longer have to depend upon the old default dialer provided by Sify.

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

Apvsys 'apvsys' is a wrapper designed to manage different versions of applications (engineering tools, compilers, debuggers, etc.). It is not a source-code version control system like CVS or RCS. Users need only one path to access all versions of all tools; they can access a default version without any setting. The application settings needed to start a tool properly are centralized by the ApVSys administrator, so there is NO setting needed for the users. Hence, all the users share exactly the same environment, which greatly reduces the support needed.
