SubnetMapper is an admin's quick tool to map and keep track of managed IP networks, track free ranges that are available for assigning, and document the network setup. It has been designed to help admins manage and document small to medium networks. It prints and displays freely colorable maps of your network.
User Manager is a supplement to the "Accounts" pane in the Mac OS X System Preferences, designed for use with small home networks. User Manager is targeted at power users who desire full control over user and group attributes, without the need to resort to using the NetInfo Manager. With it, you can create, edit, or delete users and groups in any Open Directory node (e.g. a NetInfo domain). The interface allows you to edit nearly all record attributes, including UID, GID, login shell, and home directory. You can also manage Unix group memberships using the drag-and-drop user and group-centric interfaces.
