NAME
Net::Packet::SLL - Linux cooked capture layer 2 objectSYNOPSIS
# # Usually, you do not use this module directly # use Net::Packet::Consts qw(:sll); require Net::Packet::SLL; # Build a layer my $layer = Net::Packet::SLL->new; $layer->pack; print 'RAW: '.unpack('H*', $layer->raw)."\n"; # Read a raw layer my $layer = Net::Packet::SLL->new(raw => $raw); print $layer->print."\n"; print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n" if $layer->payload;
DESCRIPTION
This modules implements the encoding and decoding of the Linux cooked capture layer.See also Net::Packet::Layer and Net::Packet::Layer2 for other attributes and methods.
ATTRIBUTES
- packetType
- Stores the packet type (unicast to us, sent by us ...).
- addressType
- The address type.
- addressLength
- The length of the previously specified address.
- source
- Source address.
- protocol
- Encapsulated protocol.
METHODS
- new
- Object constructor. You can pass attributes that will overwrite default ones. Default values:
packetType: NP_SLL_PACKET_TYPE_SENT_BY_US
addressType: NP_SLL_ADDRESS_TYPE_512
addressLength: 0
source: 0
protocol: NP_SLL_PROTOCOL_IPv4
- pack
- Packs all attributes into a raw format, in order to inject to network. Returns 1 on success, undef otherwise.
- unpack
- Unpacks raw data from network and stores attributes into the object. Returns 1 on success, undef otherwise.
- isProtocolIpv4
- isProtocolIpv6
- isProtocolIp - is type IPv4 or IPv6
- Helper methods. Return true is the encapsulated layer is of specified type, false otherwise.
CONSTANTS
