icli is a command line interface to the Icinga monitoring software. You can use it to list service/host status with many filtering options, schedule rechecks, and acknowledge service problems. Basic support for viewing the command queue and scheduled downtimes is also present. It is largely compatible with Nagios.
raps2 is a simple password safe. You give it a name, a password, and optional metadata, and it will encrypt and store them for you. It uses Eksblowfish for crypto, which offers a configurable key setup time, so you can make it as slow as you want. Each password is saved in a separate file, making it easy to track them in version control.
