Adjtimex allows command line manipulation of the kernel time keeping variables. This allows fine adjustment of the system timer without use of ntpd, which requires a constant connection with a reference timer. Adjtimex can tune your system clock so it does not drift much even without ntpd. The current version includes support for comparing your system timer to a reference source, including your RTC.
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.
Apache Toolbox provides a means to easily compile Apache (IPv4/6) SSL, PHP(v3/v4), MySQL, Jakarta, a large number of modules (61 3rd party modules and 36 default Apache modules, static or as DSOs), and GD libraries with PNG+JPEG+Freetype2+zlib support. It is fully customizable and menu-driven. Everything is compiled from source, and wget is used to download any missing modules. It can also check for RPMs that might cause problems and create an RPM with your selections.
AutoUpdate is a Perl script which performs a task similar to Red Hat's up2date or autorpm. It can be used to automatically download and upgrade RPMs from different HTTP(S) or (S)FTP sites, while also handling dependencies. Moreover, it can also be used to keep a server with a customized (Red Hat) distribution plus all clients up to date.
Bastille Unix (formerly Bastille Linux) aims to be the most comprehensive, flexible, and educational Security Hardening Program for Red Hat (Fedora Core, Enterprise Linux, and original Red Hat), SuSE, Gentoo, Mandrake, and Debian Linux, as well as HP-UX and Mac OS X. Virtually every task it performs is optional, providing immense flexibility. It educates the installing admin regarding the topic at hand before asking any question. The interactive nature allows the program to be more thorough when securing, while the educational component produces an admin who is less likely to compromise the increased security.
beep does what you'd expect: it beeps. But unlike printf("\a"), beep allows you to control pitch, duration, and repetitions. Its job is to live inside shell/perl scripts and allow more granularity than one has otherwise. It is controlled completely through command line options. It's not supposed to be complex, and it isn't - but it makes system monitoring (or whatever else it gets hacked onto) that much more informative.
