Abstract

A group of headless computer entities is formed via a local area network connection by means of an aggregation service application, operated on a headless computer entity selected as a master entity, which propagates configuration settings for time zone, application settings, security settings and the like across individual slave computer entities within the group. A human operator can change configuration settings globally at group level via a user interface display on a conventional computer having a user console, which interacts with the master headless computer entity via a web administration interface. Addition and subtraction of computer entities from a group are handled by an aggregation service application, and interlocks and error checking is applied throughout the group to ensure that no changes to a slave computer entity are made, unless those changes conform to global configuration settings enforced by the master headless computer entity.

opening an account for said client computer on a said selected computer entity having a same sub-network address.

10. The method as claimed in claim 9, wherein said step of selecting a grouped computer entity further comprises the steps of:

selecting a said grouped computer entity on the basis of maximum available data storage space.

11. The method as claimed in claim 9, wherein said step of selecting said grouped computer entity comprises:

randomly selecting one of a set of said grouped computer entities having a same sub-network address as said client computer.

12. The method as claimed in claim 9, wherein said step of setting up an account on said selected grouped computer entity comprises:

directing an executable file to said selected grouped computer entity, said executable file operating to execute set up of a user account for said client computer on said selected grouped computer entity.

14. The method as claimed in claim 13, wherein:

said master computer entity comprises a master application, said master application having a set of master application settings;

at least one slave application, resident on a corresponding slave computer entity,

wherein said slave application, is set by said set of master application configuration settings.

16. The method as claimed in claim 15, wherein:

a said master application configuration setting comprising a setting selected from the set;

an international time setting;

a default data storage capacity setting;

an exclude setting;

a user rights settings;

a data file definition setting;

19. The computer device as claimed in claim 18, wherein said user application communicates said user application configuration settings with said aggregation service application via a set of API calls.

20. The computer device as claimed in claim 18, wherein said user application comprises a master user application, which sends a set of common application configuration settings to said aggregation service applications.

21. The computer device as claimed in claim 20, wherein said user application comprises a slave application, which receives a set of application configuration settings from said aggregation service application, and applies those application configuration settings to itself.

13. A plurality of computer entities configured into a group, said plurality of computer entities comprising:
