MAPDAV (More Accurate Password Dictionary Attack Vector) is designed to use what is known about users via the /etc/passwd file on Unix/Linux systems to generate a dynamic dictionary of more accurate guesses as to what their possible password may be. It does this by mangling the user's username and user information in various user-specified ways to look for bad password protection practices.
Schedule::Cron is a Perl module that provides a simple but complete cron-like scheduler. It can be used for periodically executing Perl subroutines. The philosophy behind Schedule::Cron is to call subroutines periodically from within one single Perl program instead of letting cron trigger several (possibly different) Perl scripts. Everything under one roof. Furthermore, Schedule::Cron provides a mechanism to create crontab entries dynamically, which isn't that easy with cron. It knows about all extensions (at least all extensions the author is aware of, i.e those of "Vixie" cron) for crontab entries like ranges including 'steps', specification of month and days of the week by name, or coexistence of lists and ranges in the same field. It even supports a bit more (like lists and ranges with symbolic names). It has existed since 1999 on CPAN and is successfully used in many projects.
Osgish is a command line shell for OSGi. It is based on the Readline Library, Jmx4Perl, as the OSGi backend, and Aries JMX as the OSGi Management layer. It is different than other OSGi shells, as it is implemented in pure Perl and provides unique features like wildcard support, context-sensitive command line completion, syntax highlighting, bulk lifecycle operations, advanced query facilities, and remoting via HTTP. It uses jmx4perl and Aries JMX OSGi bundles for accessing the OSGi container remotely.
The Paranoid modules provide a number of routines that are intended for use in strict and taint-safe scripts. The modules cover a variety of tasks from command-line argument parsing to process and network management. All of the modules use a debug trace framework for diagnostic output that is easily used and extended for application code as well.
autofwd is an automated firewalling daemon intended to block hosts performing unwanted acts. While it was designed to be used to thwart hosts running dictionary attacks on logins (of any service), it can be used for just about anything. The external commands it runs are configurable, allowing you to take additional actions against offending hosts such as running an nmap OS fingerprint before firewalling, or just silently logging the event.
Class::EHierarchy is intended for use as a base class where hierarchally ordered objects are desired. This class allows you to define a parent - child relationship between objects and ensures an orderly destruction of objects according to that relationship, instead of perl's reverse order destruction sequence based on reference counting.
SYINF shows in brief a system's CPU brand and model, RAM size, disk space, operating system, regional parameters, and current date and time. It can run in interactive (menu) or batch mode. There are two versions, in the C and C++ languages. They have been tested on 20 (15) compilers, 26 (25) operating systems, and 18 architectures. (Figures in parentheses are for the C++ version.) Both versions are conveyed in source code form only, each as a single ~35 KB source text file.
