Minerva is a complete, easy to use home automation suite. It allows you to switch your on lights from anywhere using a mobile phone or PC, email your video, check CCTV footage, control your central heating, and much more. It relies on command line and can therefore be run from virtually any platform (smart phone, PDA, laptop, or remote PC) with identical functionality. The architecture consists of three parts: input, output, and process. Each is completely distinct, meaning you can control any of the house processes from any supported input conduit such as a Web browser, remote control, or SMS. Reports or notifications can be sent to any of the available output conduits.
firewall_e is a small Web application which allows administrators to create lists of servers, users, and ports and assign them to each other. This allows an administrator to login, create users, and assign ports on servers for them to access. Users can login and their remote IP address will be stored. From this address, they'll then be able to access whatever services the administrator provided them.
sc-tool is a commandline tool intended to simplify administration of traffic shapers for Internet Service Providers. It features fast loading of large rulesets using batch modes of tc and ipset, loading of information from any SQL database supported by Perl DBI, a batch command execution mode, and synchronization of rules with databases.
Crypt::IDA is a Perl module that implements Rabin's Information Dispersal Algorithm. This is what's known as a "threshold system": a secret is divided into n shares with the property that any k (the "quorum" or "threshold") of those shares (with k <= n) can be combined at a later time to reconstruct the secret. The algorithm should be cryptographically secure in the sense that if fewer shares than the quorum k are presented, no information about the secret is revealed. The module uses Math::FastGF2 to efficiently implement the algorithm, making it suitable for securely sharing and distributing even large files. The Crypt::IDA::ShareFile module implements a file format for creating, storing, and distributing shares created with Crypt::IDA.
