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.
slackeria takes a list of projects and checks whether they are present in certain places, such as freshmeat or various distributions. If they are, their version is also reported. This makes it easy to monitor projects and, for example, to notify distributions of updates when they are lagging behind.
ssh-forcecommand is a script to safely execute remote commands via ssh. It is especially aimed at automated remote commands (in which ssh keys are not secured via password), where a compromise of the remote system could also compromise the local system. To prevent this, ssh-forcecommand can be invoked through the ssh configuration, which will limit the remote system so that it can only execute a set of statically defined commands. This way, compromising the local system is made much more difficult.
