The following are operating system requirements for Star:

UNIX: The executable setuid must be turned on. Only the user who owns the installation can start the Star Server. The install sets up the correct protections (that is, setuid) on the Star Server.

VMS: The Star Server requires the following privileges to run: PRMMBX, WORLD, READALL (for client/server communication), SYSPRV (to open error and status logging files), and SHARE (to open terminals for trace output). The vmsinstal utility installs the Star Server with all of the appropriate permissions.
