Data::Netflow - Module to process binary netflow data (v5 and v9)
Version 0.02
Module to create netflow binary data from text data
use Data::Netflow; use IO::Socket; my $sock_udp = IO::Socket::INET->new( Proto => 'udp', PeerPort => 9995, PeerAddr => '127.0.0.1', ) or die "Could not create UDP socket: $!\n"; my $TemplateV9 = { 'FlowSetId' => 0, 'TemplateId' => 300, 'Fields' => [ { 'Length' => 4, 'Id' => 1 }, # octetDeltaCount { 'Length' => 4, 'Id' => 2 }, # packetDeltaCount { 'Length' => 1, 'Id' => 4 }, # protocolIdentifier { 'Length' => 1, 'Id' => 6 }, # tcp flags { 'Length' => 2, 'Id' => 7 }, # sourceTransportPort { 'Length' => 4, 'Id' => 8 }, # sourceIPv4Address { 'Length' => 2, 'Id' => 11 }, # destinationTransportPort { 'Length' => 4, 'Id' => 12 }, # destinationIPv4Address { 'Length' => 4, 'Id' => 21 }, # last switched { 'Length' => 4, 'Id' => 22 }, # first switched ], } my $Header = { Version => 9, SysUptime => int ( uptime() *1000 ), }; my @flow; my @tmp = qw( 5 8126 17 0 22 10.2.1.1 5365 10.2.1.254 ) ; my $uptime = int ( (uptime()- $back ) *1000 ); push @tmp , $uptime + 5; push @tmp , $uptime; push @flow , \@tmp; my $encoded = Data::Netflow::encodeV9($Header, $TemplateV9 ,\@flow); $sock_udp->send( $encoded );
