The rmsg messaging system can be used to send write(1)-like messages to
|
|
logged-on users. The system can cross machine boundaries: if another machine
|
|
has rmsgd running, you can send messages to users on it.
|
|
The system allows bitnet virtual machine-like 'virtual users' to whom
|
|
any user can send messages and they can answer the messages. The rmsgd server
|
|
makes this possible by allowing a command 'exec' in a user's .msgconf file, and
|
|
whenever the user receives a message this command is executed and the message is
|
|
piped to it.
|
|
It is possible to log incoming and outgoing messages. You can specify a
|
|
file to which the last (or every) incoming message will be stored.
|
|
Rmsgd is the server daemon for the system. It should be started by
|
|
root, but for now it works even if started by ordinary users, even though some
|
|
capabilities are disabled for security reasons (that is, exec and logging of
|
|
incoming messages, since that would be done by the user-id who started rmsgd and
|
|
not the receiver).
|
|
The server should be named 'rmsgd' to have it start as a daemon. Rmsg
|
|
is the client end of the system. Rmsg is used by ordinary users to send
|
|
messages. For example, rmsg foo@bar hello there ! ^D would send a message
|
|
'hello there !' to user foo at machine bar. By default, rmsg stores the last
|
|
outgoing message in the user's home directory in the file .msgout. Then msg -r
|
|
user@machine can be used to resend the message. Messages are normally read from
|
|
standard input until EOF.
|
|
There are many options which can be set in a user's ~/.msgconf' file.
