ARP Neighbor Cache Fingerprinter is a tool that provides a mechanism for remote operating system detection by extrapolating characteristics of the target system's underlying neighbor cache and general ARP behavior. Given the non-existence of any standard specification for how the neighbor cache should behave, several differences in network stack implementations can be used for unique identification. The main disadvantage of this tool versus traditional fingerprinting is that because it's based on a Layer 2 protocol instead of a Layer 3 protocol, the target machine that is being tested must reside on the same Ethernet broadcast domain (usually the same physical network).
HomeGed Scan is scanning software that was designed to offer power as well as simplicity of use. Acquired or imported files can be combined into multi-page documents and saved in formats such as PDF, TIFF, JPEG, and PNG. It supports network scanners using TWAIN or SANE protocols and flat-beds and document feeders.
Metrix++ is a platform to collect and analyze code metrics. It has a plugin-based architecture, so it is easy to add support for new languages, define new metrics, and/or create new pre- and post-processing tools. Every metric has 'turn-on' and other configuration options. There are no predefined thresholds for metrics or rules; you can choose and configure any limit you want. It scales well to large codebases. For example, initial parsing of about 10000 files takes 2-3 minutes on an average PC, and only 10-20 seconds for iterative re-run. Reporting summary results and exceeded limits takes less than 1 - 10 seconds. It can compare results for 2 code snapshots (collections) and differentiate added regions (classes, functions, etc.), modified regions, and unchanged regions. As a result, easy deployment is guaranteed into legacy software, helping you to deal with legacy code efficiently, and either enforce the 'leave it not worse than it was before' rule or motivate re-factoring.
Paperless Office is a document management and electronic filing system. It is similar to Paperport, but adds many new features, such as automatic document classification, synchronization with your filing cabinet, date extraction, semantic Web integration, and sophisticated natural language processing, such as extracting todo lists from documents, spam detection, urgency classification, along with planning, scheduling, and execution features. You can set due dates and interdependencies for documents and tasks, so it has workflow support.
sslsweep tests TCP services for the presence of SSL and reports things about the services found, such as the certificate's CN, the certificate's expiration timestamp, what kinds of ciphers the SSL service supports, and what versions of SSL the service supports. It can be used for security testing as well as ongoing monitoring of services. It can produce output in human readable text, HTML, and CSV. It can also run as a Nagios plugin. It can accept input on the command line or on standard input (one host:port pair per line). It can also accept Nmap scan output (in the greppable format) as input, and it will test all open TCP ports found by the Nmap scan.
YAGF is a graphical frontend for the cuneiform and tesseract OCR tools. It lets you open already scanned image files or obtain new images via XSane (scanning results are automatically passed to YAGF). Once you have a scanned image you can prepare it for recognition, select particular image areas for recognition, set the recognition language and so on. Recognized text is displayed in an editor window where it can be spell-checked, corrected, saved to disk, or copied to clipboard. YAGF also provides some facilities for a multi-page recognition.
enhance_book_photo is a command-line tool for enhancing photographs of pages from books. On such photos, the light is usually not equal on all parts of the picture; some parts are brighter, some parts are darker. This can disrupt OCR or reduce the efficiency of conversion to djvu. enhance_book_photo equalizes the brightness of such photos.
geoipgen is an IP network tool for generating geotargeted lists of IP addresses using MaxMind's GeoLite Country database. It can randomly enumerate all IP addresses or a specified number of IP addresses in a particular country or a list of countries. For example, to get all IPs for Japan in a random order, use "geoipgen jp". For a sample of 10,000 IPs from Australia and New Zealand, use "geoipgen -n 10000 au nz".
