22. The projection device of claim 12, wherein the moving mechanism manually moves the secondary housing.
23. The projection device of claim 12, wherein the first external contour is substantially the same as the third external contour.
24. The projection device of claim 12, wherein the first external contour is substantially different from the third external contour.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A process comprising:
in response to requests from a manager for connections to applications executing on servers, authenticating of said manager by agents executing on said servers;
in response to said authenticating, establishing connections to said applications by said agents; and
in response to said establishing, providing by said agents to said manager said connections to said applications.
2. A process as recited in claim 1 wherein said authentication involves using a same certificate by plural agents.
3. A process as recited in claim 1 further comprising:
said servers authenticating said manager; and
in response to said authenticating, said manager installing said agents on said servers.
4. A process as recited in claim 3 further comprising said agents listening for said manager on specified virtual ports and not on other virtual ports.
5. A process as recited in claim 1 further comprising said manager updating said applications using said connections.
6. A system comprising storage media encoded with code that, when executed by a processor, implements an agent, said agent including:
a manager interface to interface with a remote manager to receive or fulfill a request by said manager for access to an application executing on a same server as said agent, said manager interface including an authenticator for authenticating said manager; and
an application interface to provide a connection between said agent and said application so that said manager interface can provide a connection between said manager and said application.
7. A system as recited in claim 6 further comprising said processor.
8. A system as recited in claim 6 wherein said code further implements said application, said application including a user authenticator for authenticating a user requesting access to said application, said agent being configured to bypass said user authenticator.
