RWALL(1)                                                    BSD General Commands Manual                                                   RWALL(1)

NAME

     rwall -- send a message to users logged on a host

SYNOPSIS

     rwall host [file]

DESCRIPTION

     The rwall command sends a message to the users logged into the specified host. The message to be sent can be typed in and terminated with EOF
     or it can be in a file.

DIAGNOSTICS

     rwall: RPC: Program not registered
             The rpc.rwalld(8) daemon has not been started on the remote host.

     rwall: RPC: Timed out
             A communication error occurred.  Either the network is excessively congested, or the rpc.rwalld(8) daemon has terminated on the
             remote host.

     rwall: RPC: Port mapper failure - RPC: Timed out
             The remote host is not running the portmapper (see portmap(8) ), and cannot accommodate any RPC-based services.  The host may be
             down.

SEE ALSO
