NAME
Net::Packet::UDP - User Datagram Protocol layer 4 objectSYNOPSIS
use Net::Packet::Consts qw(:udp); require Net::Packet::UDP; # Build a layer my $layer = Net::Packet::UDP->new( dst => 31222, ); $layer->pack; print 'RAW: '.unpack('H*', $layer->raw)."\n"; # Read a raw layer my $layer = Net::Packet::UDP->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 UDP layer.RFC: ftp://ftp.rfc-editor.org/in-notes/rfc768.txt
See also Net::Packet::Layer and Net::Packet::Layer4 for other attributes and methods.
ATTRIBUTES
- src
- dst
- Source and destination ports.
- length
- The length in bytes of the datagram, including layer 7 payload (that is, layer 4 + layer 7).
- checksum
- Checksum of the datagram.
METHODS
- new
- Object constructor. You can pass attributes that will overwrite default ones. Default values:
src: getRandomHighPort()
dst: 0
length: 0
checksum: 0
- recv
- Will search for a matching replies in framesSorted or frames from a Net::Packet::Dump object.
