  • PC-BSD’s New ControlPanelThis article introduces the new Control Panel that will ship withPC-BSD 9.0. Readers are encouraged to try out the Control Panelprior to release by downloading a PC-BSD 9.0 testing snapshot orbuilding the Control Panel on a PC-BSD 8.x system or a FreeBSD8.x system that has Xorg configured.P C-BSD 9.0, due for release later this year, will Panel makes it easy for users to find and use a consistent introduce a graphical Control Panel for the set of tools to configure their system, regardless of which administration of a BSD system. Prior releases of desktop environment they are currently logged into.PC-BSD added some BSD-specific configuration utilitiesto those already provided by the KDE System Settings Control Panel Featuresmenu. Figure 1 shows a screenshot of System Settings Kris Moore created the initial design of the Control Panelfrom a PC-BSD 8.2 system. and Yuri Momotiuk extended the design to include support While System Settings contains most of the utilities needed for localizations and the ability to include the configurationto configure a system, it does not distinguish between whichutilities came with KDE and which were custom created forPC-BSD. For example, under the Network and Connectivitysection shown in Figure 1, Network Settings and Sharingare KDE utilities. The Firewall utility was created by the PC-BSD project to provide graphical access to the PF firewalland the System Network Configuration utility was created tounderstand FreeBSD network device names, wpa_supplicant,ppp.conf, and rc.conf. One of the design features of PC-BSD 9.0 is the ability forusers to install multiple desktop environments both duringand after installation of the operating system. Users canchoose from the following desktop environments: KDE4,GNOME2, XFCE4, LXDE, Awesome, Enlightenment,IceWM, ScrotWM, and Window Maker. Since each desktopenvironment installs its own set of configuration utilities,there is a clear need for a unified Control Panel. A Control Figure 1. System Settings Menu 12 07/2011
