Net::Packet is a packet construction framework, you can build packets from Layer 2 to Layer 7. It really made easy to match requests with replies, and hides many trivial tasks that you must do by hand using Net::Pcap/Net::RawIP/NetPacket. Actually on CPAN, the 1.28 version. I'm finalising the 2.00, which features IPv6 headers as well, and full documentation (not terminated). You can get the 2.00-RC1 here: http://www.gomor.org/netpkt/Net-Packet-2.00-RC1.tar.gz Example SYN send with 2.00-RC1 version (not compatible with 1.28): --8<-- #!/usr/bin/perl use Getopt::Std; my %opts; getopts('i:I:p:d:v', \%opts); die "Usage: send-syn.pl -i dstIp -p dstPort [-v]\n" unless $opts{i} && $opts{p}; use Net::Pkt; $Env->debug(3) if $opts{v}; my $ip = Net::Packet::IPv4->new(dst => $opts{i}); my $tcp = Net::Packet::TCP->new( flags => NP_TCP_FLAG_SYN, dst => $opts{p}, ); my $frame = Net::Packet::Frame->new(l3 => $ip, l4 => $tcp); print "Request:\n"; print $frame->ipPrint, "\n"; print $frame->tcpPrint, "\n"; $frame->send; until ($Env->timeout) { if ($frame->recv) { print "\nReply:\n"; print $frame->reply->ipPrint, "\n"; print $frame->reply->tcpPrint, "\n"; last; } } --8<-- -- ^ ___ ___ FreeBSD Network - http://www.GomoR.org/ <-+ | / __ |__/ Security Engineer, searching for work | | \__/ | \ ---[ zsh$ alias psed='perl -pe ' ]--- | +--> Net::Packet <=> http://search.cpan.org/~gomor/ <--+
