SunScreen EFS 3.0 automatically chooses a name for each Screen based on the hostname setting output by uname -n. There are various situations in which this name is used as an IP host name (IP address) for remote administration and centralized management groups.
Therefore, it is necessary for each Screen's name to be defined as a valid IP address for that Screen. The definition must be accessible through /etc/hosts, NIS or DNS on every remote administration station as well as every Screen in a centralized management group.
