NAME

rwall - Write to all users over a network  

SYNOPSIS

/usr/sbin/rwall hostname...

/usr/sbin/rwall -n netgroup...

/usr/sbin/rwall -h hostname -n netgroup


 

OPTIONS

Send the broadcast message to the specified network groups. Specify the hostname, the name of the host.
 

DESCRIPTION

The rwall command reads a message from standard input until end-of-file. It then sends the following message to all users logged in on the specified host machines, preceded by the line:

Broadcast Message ...

With the -n option, it sends to the specified network groups.

Note, the timeout is fairly short to allow transmission to a large group of machines (some of which may be down) in a reasonable amount of time. Thus the message may not get through to a heavily loaded machine.

A remote host only responds if it is running the rwalld daemon, which is normally started up from inetd(8).
