NAME
Net::Packet::NULL - BSD loopback layer 2 objectSYNOPSIS
# # Usually, you do not use this module directly # use Net::Packet::Consts qw(:null); require Net::Packet::NULL; # Build a layer my $layer = Net::Packet::NULL->new; $layer->pack; print 'RAW: '.unpack('H*', $layer->raw)."\n"; # Read a raw layer my $layer = Net::Packet::NULL->new(raw => $raw); print $layer->print."\n"; print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n" if $layer->payload;
