- RUsers Prototype 9209A demonstrates a graphical interface to the
- rusers protocol. It is a complete reimplementation rather than
- a front end to the command-line rusers program. While this
- version only runs under NeXTstep, it is capable of monitoring any
- system which provides the rusers version 2 RPC server. [While
- that includes VAX/VMS systems with TGV MultiNet, VMS users will
- never appear to be logged onto the "console" device.] Note that
- NeXT managed to "break" rpc.rusersd in Release 2.0 (it's prone to
- dropping dead, particularly when no one's logged in). I
- understand that this is only one of several network programs
- known to be buggy in 2.x that NeXT still has NOT fixed in 3.0.
- You won't have problem with Sun (or any other UNIX vendor I'm
- aware of)--theirs "just works ... out of the box."

- Documentation:
-
- README This file.
- MapView.rtf Description of the class that does most
- of the grunt work.
-
- Executables:
-
- RUsers.app Executable and friends.
- 1.0/rpc.rusersd Viable replacement for NeXT's broken
- /usr/etc/rpc.rusersd in NeXT Software
- Release 2.x.

- Images with reserved names:
-
- down.tiff Machine doesn't respond.
- (Raised arrow pointing downward.)
- nobody.tiff Machine is up, no users.
- (Raised arrow pointing upward.)
- somebody.tiff Someone logged in remotely.
- (As above, with dot.)
- unknown.tiff Someone logged into console, no NeXT Mail
- picture. (Generic face.)
- balloon.tiff Cursor to display when mouse down will do
- something interesting. Its "hot spot" is
- hardcoded in the sample application. :-(
-
- Images that may or may not be useful:
-
- macrgb.tiff Macintosh(R) RGB monitor (to represent
- A/UX). {24,45,64,64}
- macII.tiff Same, but resting on top of a Mac II.
- megapixel.tiff NeXT grayscale display. {21,35,64,64}
- pint-of-milk.tiff Can be used for machines whose pictures
- are "missing." {2,13,64,64}
- quart-of-milk.tiff Ditto. {2,98,64,64}
-
- Numbers in {braces} indicate suggested "people" inlay.
-
- sef+.tiff The search for NeXT Mail pictures can be
- preempted by placing an appropriately-
- named file in the .app wrapper.

-
- Before you can use RUsers, you'll need to create a configuration
- file describing your network. (The format is described in
- MapView.rtf.) When RUsers starts up, it looks at the NXOpen
- default for the name of the configuration file to use. If that
- doesn't work, it looks in its .app wrapper for config@<hostname>
- where <hostname> is replaced by your hostname string (unless it
- happens to be localhost), and then simply config.
-
- Other trivia: The position and size of the window is saved in the
- MapFrame default. (This is actually describes the content
- rectangle.) A different strategy will be needed if a future
- version supports multiple MapViews.
-
- When the "Update" menu item undims, RUsers is no longer obtaining
- current information. Click to initiate another survey.

- --> I want more machine images! (Especially the popular ones.)
