ntping itself cannot ping entire networks by telling it ``this is
class b''; maybe this would be a nice feature for others too.
ntping can ping many hosts by specifying them on the commandline or
stdin.
please have in mind that your host may drop packets to be sent, in the
network-layer, because they possibly couldn't sent so fast as they
arrive from ntping. if this happens tune the -delay parameter a little
bit.
anyway, you need a script (tcl, perl, shell, ...) wrapped around the
ntping call, to create the ip addresses argument.
or you may like to look at
scotty-2.1.0/tnm/examples/discover
as an example how to do this with scotty (to use the discover script
as-is patch the scotty command in line 3 to scotty2.1.0).
