инструмент генерации сетевых пакетов / утилита ping (Network packet generation tool / ping utility)
ETHERNET OPTIONS
In most cases Nping sends packets at the raw IP level. This means
that Nping creates its own IP packets and transmits them through
a raw socket. However, in some cases it may be necessary to send
packets at the raw Ethernet level. This happens, for example,
when Nping is run under Windows (as Microsoft has disabled raw
socket support since Windows XP SP2), or when Nping is asked to
send ARP packets. Since in some cases it is necessary to
construct ethernet frames, Nping offers some options to
manipulate the different fields.
--dest-mac mac (Ethernet Destination MAC Address)
This option sets the destination MAC address that should be
set in outgoing Ethernet frames. This is useful in case Nping
can't determine the next hop's MAC address or when you want
to route probes through a router other than the configured
default gateway. The MAC address should have the usual format
of six colon-separated bytes, e.g. 00:50:56:d4:01:98.
Alternatively, hyphens may be used instead of colons. Use the
word random or rand to generate a random address, and
broadcast or bcast to use ff:ff:ff:ff:ff:ff. If you set up a
bogus destination MAC address your probes may not reach the
intended targets.
--source-mac mac (Ethernet Source MAC Address)
This option sets the source MAC address that should be set in
outgoing Ethernet frames. This is useful in case Nping can't
determine your network interface MAC address or when you want
to inject traffic into the network while hiding your network
card's real address. The syntax is the same as for
--dest-mac. If you set up a bogus source MAC address you may
not receive probe replies.
--ether-type type (Ethertype)
This option sets the Ethertype field of the ethernet frame.
The Ethertype is used to indicate which protocol is
encapsulated in the payload. type can be supplied in two
different ways. You can use the official numbers listed by
the IEEE--ether-type 0x0800 for IP version 4), or
one of the mnemonics from the section called 'Ethernet
Types'.
