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.
AlmostVPN is an SSH tunnel manager with a twist. It is packaged as a Preference Panel, so you do not have to use yet another application to configure your tunnels. Instead, it uses creative network configuration techniques to provide almost VPN-like access to remote services, so you can keep using real IP addresses and port numbers while accessing service on the other side of your tunnels. It provides a simple way to mount remote volumes, use remote printers and faxes, access iTunes, iPhoto, and almost any other Bonjour-based application, transfer and execute files, and more.
