x509watch is a simple command line application that can be used to list soon expiring or already expired X.509 certificates, such as SSL certificates. All certificates are searched by default in the standard PKI directory, but any other directory can be specified as a parameter. Only Base64 encoded DER and PEM X.509 certificates are supported.
HDT (Hardware Detection Tool) is an OS independent tool that displays low-level information on any x86 compatible system. It detects ACPI, CPU, PCI devices, DMI (memory, BIOS, motherboard, IPMI base board, chassis, batteries, CPU), disks (geometry, partitions), PXE environment, VESA modes, and VPD. It can also deduce the Linux kernel modules needed by a given host.
NConf is a Web tool for configuring the Nagios monitoring software. It differs from similar tools by offering enterprise-class features like templates, dependencies, and the ability to configure a large-scale, distributed Nagios server topology. It lets you effortlessly maintain a distributed Nagios topology. It has a user-friendly GUI. It features host and service templates, a graphical dependency viewer, multiple authentication modes, a Nagios configuration importer, a CSV file importer, and a Perl database API. The data schema is customizable and expandable.
The CPAN shell (and module) automates or at least simplifies the building and installation of Perl modules and extensions. It includes some primitive searching capabilities and knows how to use Net::FTP, LWP, and certain external download clients to fetch distributions from the Internet. Then it automatically tests and installs them and their dependencies.
Ximinez is a disk usage analyzer and comparator. It enables you to take snapshots of disk usage for a given folder, to browse through the snapshots, and to view differences between snapshots. It is aimed towards solving problems like: "Why is my disk suddenly so full when it was OK just recently?" Besides the GUI, the package also includes an optional command line tool, which can be used, for example, in conjunction with a scheduler to take snapshots on a regular basis.
jidgen is a Java-based id generator that can be used as a command line program or as a library. The idea is to make automated generation of user IDs as easy as possible by introducing a simple, straightforward template language to describe the structure of the desired IDs. jidgen uses 100% Java and is thus platform independent. Itsupports collision filters for different backends to ensure the generated ID is unique in your environment. Blacklists are available to make sure all IDs are socially acceptable. As a command line program, it can easily be accessed by scripts or directly by the user. As an embedded library, it can easily be employed in the process of automated ID generation and suggestion.
Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable. A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.
