_R_w_a_l_l reads a message from standard input until end-of-file. It then
sends this message, preceded by the line ``Broadcast Message ...'', to
all users logged in on the specified host machines. With the ----nnnn option,
it sends to the specified network groups, which are defined in
_n_e_t_g_r_o_u_p(4).
A machine can only receive such a message if it is running _r_w_a_l_l_d(1m),
which is normally started up by the daemon _i_n_e_t_d(1m).

The timeout is fairly short in order to be able to send 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.
