Starting with the Solaris 10 3/05 release, you can now create a more secure system with fewer enabled network services by selecting or specifying the Reduced Networking software group (SUNWCrnet) during your installation. The Reduced Networking software group provides system administration utilities and a multiuser text-based console. SUNWCrnet enables the system to recognize network interfaces. During the installation, you can customize your system's configuration by adding software packages and by activating network services as needed.
