class PacketGen::Header::Eth
An Ethernet header consists of:
-
a destination MAC address ({MacAddr}),
-
a source MAC address (
MacAddr
), -
a {#ethertype} ({Types::Int16}),
-
and a body (a {Types::String} or another
Header
class).
Create a Ethernet header¶ ↑
# standalone eth = PacketGen::Header::Eth.new # in a packet pkt = PacketGen.gen('Eth') # access to Ethernet header pkt.eth # => PacketGen::Header::Eth
Ethernet attributes¶ ↑
eth.dst = "00:01:02:03:04:05" eth.src # => "00:01:01:01:01:01" eth[:src] # => PacketGen::Header::Eth::MacAddr eth.ethertype # => 16-bit Integer eth.body = "This is a body"
