[Samba] sending broadcast messages (-M)

[Paul Miller]

Is it possible to send a broadcast message to all computers in the
workgroup/domain?  I didn't seen an option for smbclient to send a message
to more than one computer.  Basically, I'd like to do something like this:

echo "my message" | smbclient -M * -W WORKGROUP

and have that message popup on all the computers of the WORKGROUP workgroup.

Thanks,
Paul Miller
