NAME
Net::Packet::DescL4 - object for a transport layer (layer 4) descriptorSYNOPSIS
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.
