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.
