rConfig is a network device configuration management utility for network engineers to take frequent configuration snapshots of their network devices. It lets you choose which commands you want to run against your devices. Simply configure rConfig with the list of commands you wish to apply to a category of devices, and add devices to the category. Create a scheduled task, and rConfig will do the rest.
wmphoto+ displays the images in the dockable application window. You can switch the images manually or display them as a slide show. Each image accepts up to two related commands. You can run them using mouse buttons when the application displays the image. Using the alternative configuration directories, you can run a few instances of the program that display the different sets of images.
keychain helps you to manage ssh keys in a convenient and secure manner. It acts as a frontend to ssh-agent and gpg-agent, but allows you to easily have one long running ssh-agent process per system, rather than the norm of one ssh-agent per login session. This dramatically reduces the number of times you need to enter your passphrase. With keychain, you only need to enter a passphrase once every time your local machine is rebooted. keychain also makes it easy for remote cron jobs to securely "hook in" to a long running ssh-agent process, allowing your scripts to take advantage of key-based logins.
