NAME¶
Net::Frame::Layer::ICMPv6 - Internet Control Message Protocol v6 layer object
SYNOPSIS¶
use Net::Frame::Simple;
use Net::Frame::Layer::ICMPv6 qw(:consts);
my $icmp = Net::Frame::Layer::ICMPv6->new(
type => NF_ICMPv6_TYPE_ECHO_REQUEST,
code => NF_ICMPv6_CODE_ZERO,
checksum => 0,
);
# Build an ICMPv6 echo-request
use Net::Frame::Layer::ICMPv6::Echo;
my $echo = Net::Frame::Layer::ICMPv6::Echo->new(payload => 'echo');
my $echoReq = Net::Frame::Simple->new(layers => [ $icmp, $echo ]);
print $echoReq->print."\n";
# Build an ICMPv6 neighbor-solicitation
use Net::Frame::Layer::ICMPv6::NeighborSolicitation;
my $solicit = Net::Frame::Layer::ICMPv6::NeighborSolicitation->new(
targetAddress => $targetIpv6Address,
);
$icmp->type(NF_ICMPv6_TYPE_NEIGHBORSOLICITATION);
my $nsReq = Net::Frame::Simple->new(layers => [ $icmp, $solicit ]);
print $nsReq->print."\n";
#
# Read a raw layer
#
my $layer = Net::Frame::Layer::ICMPv6->new(raw => $raw);
print $layer->print."\n";
print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"

See also
Net::Frame::Layer for other attributes and methods.
ATTRIBUTES¶
- type
- code
- Type and code fields. See CONSTANTS.
- checksum
- The checksum of ICMPv6 header.
The following are inherited attributes. See
Net::Frame::Layer for more
information.
- raw
- payload
- nextLayer
METHODS¶
- new
- new (hash)
- Object constructor. You can pass attributes that will overwrite default
ones. See SYNOPSIS for default values.
- computeChecksums
- Computes the ICMPv6 checksum.
- getKey
- getKeyReverse
- These two methods are basically used to increase the speed when using
recv method from Net::Frame::Simple. Usually, you write them
when you need to write match method.
- match (Net::Frame::Layer::ICMPv6 object)
- This method is mostly used internally. You pass a
Net::Frame::Layer::ICMPv6 layer as a parameter, and it returns true
if this is a response corresponding for the request, or returns false if
not.
The following are inherited methods. Some of them may be overridden in this
layer, and some others may not be meaningful in this layer. See
Net::Frame::Layer for more information.
- layer
- computeLengths
- computeChecksums
- pack
- unpack
- encapsulate
- getLength
- getPayloadLength
- print
- dump
