The two main ones are dpkg-reconfigure and gadmin. dpkg-reconfigure This utility reruns the same configuration scripts that run during installation. It is run from the command line, and options can be used to vary the level of complexity of the questions asked. It is generally used when extensive, local modifications aren't required and the administrator just wants to update the basic configuration as provided by the installation scripts. It is also useful if the basic configuration has been corrupted, or changes made that have caused the package to stop working, to return it to the configuration provided immediately after installation. It is generally not useful if the configuration requires options that are not commonly used, or if the configuration requires extensive local modifications that aren't normally covered by the installation scripts, except perhaps to return the configuration to a post-installation condition as noted previously. gadmin This is actually a suite of packages, each covering a different major service. Unfortunately, this is not as universal as dpkg-reconfigure, but it does handle more complex configurations. The following services are covered as of Debian 7: Bind (DNS) OpenVPN (both client and server) ProFTPD (FTP) RSYNC Samba (Windows Shares) It is a graphical tool, based on GTK (GIMP Tool Kit). It was developed to provide some administrator functions under the GNOME desktop environment. It will handle fairly complex configurations. Desktop configuration So far, we have been discussing server configuration. User configuration of a desktop environment is actually a little easier, as both GNOME (GNU Object Model Environment) and KDE (K Desktop Environment), as well as other desktop managers, provide a full suite of utilities gathered in one menu area that allows the user to easily configure things such as desktop appearance, behavior, window themes, login behavior, and system and session services relevant to their surroundings. Other utilities Finally, there are a number of packages that were created for the express purpose of configuring individual services. There are software packages that provide graphic or command line configuration tools for any number of other software packages. The packages vary in complexity and usage, as they are usually provided by third parties. They can be found by using any of the search capable Debian package managers. Synaptic is probably the easiest as it allows one to easily browse descriptions after looking out. observe Many of the third-party utilities are not aware of modifications Debian makes to the configuration file layout in order to ease administration, upgrades, and balance. Often, they use the upstream configuration file layout, or sometimes even the author's idea of a better layout. Although the Debian package upgrade procedure will handle this as a local configuration file modification, it does make extra work for the administrator during upgrades. Keep this in mind when deciding whether to use third-party configuration utilities.
