 rwall(1M)                                                         rwall(1M)

 NAME    [Toc]    [Back]
      rwall - write to all users over a network

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/rwall hostname ...

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

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

 DESCRIPTION    [Toc]    [Back]
      rwall reads a message from standard input until EOF, then sends the
      message, preceded by the line Broadcast Message ..., to all users
      logged in on the specified host machines.  With the -n option, rwall
      sends the message to the specified network hosts defined in
      /etc/netgroup (see netgroup(4)).

      A machine can only receive such a message if it is running rwalld,
      which is normally started from /etc/inetd.conf by the inetd daemon
      (see inetd(1M)).

 WARNINGS    [Toc]    [Back]
      The timeout is kept fairly short so that the message can be sent 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.

 AUTHOR    [Toc]    [Back]
      rwall was developed by Sun Microsystems, Inc.
