- This software has been tested on Sun3, Sun4, mips, and SGI.
- It is currently in use here on these platforms.
- The original author was Hyman Wong, and there have been significant
- upgrades and modifications made by Reg Quinton and myself.
-
- Sendopr allows users to send messages to the operator.
- It is a queuing system which delivers messages to an operator's
- Xterminal. Xmessage is used to display the information.
-
- Multi-line messages can come from standard input if the user
- is not a tty. The messages appear on the operator's console
- which is assumed to be an Xterminal.
- The geometry of the window should be defined in the operator's
- .xdefaults file: see man page for more details.
-
- To install:
- 1. make
-
- 2. Include a line in /etc/services similar to:
- sendopr xxx/tcp
- Where xxx is the port number to be used for the service
- for sendoprd.
-
- 3. Include a line in /etc/inetd.conf similar to:
- sendopr stream tcp nowait nobody /usr/ccs/lib/sendoprd sendoprd
-
- 4. Then execute the command:
- kill -HUP "pid of inetd"
- For kill: Arguments should be jobs or process id's.
- This will reinitialize inetd.

- Sendopr was written by me, Hyman Wong, for the department of Computing
- and Communications Services at the University of Western Ontario. I am
- a student working here as a consultant and applications programmer.
- Sendopr is a program utility that allows users to send a message to the
- operator's terminal. Sendopr was written to reduce the clutter on the
- operator's screen by opening up an xmessage window at the same place on
- the operator's display.

-
- Sendopr sends things to the daemon via E-mail. This requires an E-mail
- pipe like
-
- sendopr: "|/usr/ccs/lib/sendord"
-
- in /usr/lib/aliases.

- Brian Borowski:
- Mar. 31, 1992, Revised sendoprd.c to use advisory locks on the .busy file.
- This will let the program execute when it is supposed to.
- Resolves the problem with .busy file lock up.
-
- April 9, 1992 (Brian Borowski)
- The shell script sendopr was rewritten in C and this implementation
- has been done as a client using a host on the net when messages
- are to be queued. In all other respects I have attempted to
- duplicate the behaviour of the shell script version of sendopr.
-
- April 16, 1992 (Brian Borowski)
- Performed upgrade to fix the getuser problem which arose when the
- program was being run with no tty (for example, from cron.)
- Also modified interface so that the input for the message could come
- from standard input, rather than just the command line.
