NAME
Net::Packet::DescL4 - object for a transport layer (layer 4) descriptor
SYNOPSIS
require Net::Packet::DescL4;
# Get NP_DESC_* constants
use Net::Packet::Consts qw(:desc :layer);
# Usually, you use it to send TCP and UDP frames over IPv4
my $d4 = Net::Packet::DescL4->new(
target => '192.168.0.1',
protocol => NP_DESC_IPPROTO_TCP,
family => NP_LAYER_IPv4,
);
$d4->send($rawStringToNetwork);DESCRIPTION
See also Net::Packet::Desc for other attributes and methods.
ATTRIBUTES
- target
-
IPv4 address of the target host. You must set it to be able to send frames.
- protocol
-
Transport protocol to use, see NP_DESC_IPPROTO_* constants in Net::Packet::Desc. You must set it to be able to send frames.
- family
-
The family address of target attribute. It is either NP_LAYER_IPv4 or NP_LAYER_IPv6.
METHODS
- new
-
Create the object, using default $Env object values for dev, ip, ip6 and mac (see Net::Packet::Env). When the object is created, the $Env global object has its desc attributes set to it. You can avoid this behaviour by setting noDescAutoSet in $Env object (see Net::Packet::Env).
Default values for attributes:
dev: $Env->dev
ip: $Env->ip
ip6: $Env->ip6
mac: $Env->mac
protocol: NP_DESC_IPPROTO_TCP
family: NP_LAYER_IPv4
- isFamilyIpv4
- isFamilyIpv6
- isFamilyIp - either one of two previous
-
Helper method to know about the layer 3 type.
- isProtocolTcp
- isProtocolUdp
- isProtocolIcmpv4
-
Returns if the protocol attribute is of specified type.
