Hi all,

In short and attached downwards:

Hey guys,

I'm putting together a perl script to do some HTTP manipulation (Methods,
versions, overflow strings, etc), and am having some trouble reading from the
socket.  From tcpdump, I can see that it is completing the TCP three way
handshake, and successfully GETting the default page with a 200 OK response,
but I'm not sure how to capture this data from the socket prior to closing
it.  Could any of you PERL gurus see if I've missed something important here?
Thanks,
 
#!c:\Perl\bin\Perl.exe
use CGI qw(:standard);
#use strict;
use Socket;

#Initialize the host, port, and protocols
$host = shift||'ip.address.of.remote.host';
$port = shift||80;
$proto = getprotobyname('tcp');

#Get the port address
$remoteip = inet_aton($host);
$remoteport = sockaddr_in($port,$remoteip);

#$localhost   = pack('S n a4 x8', AF_INET, 0, "\0\0\0\0");
#$remotehost   = pack('S n a4 x8', AF_INET, $port, $host);

#Create the socket and connect to the port
socket(SOCKET,PF_INET,SOCK_STREAM,$proto) or die "socket:$!";
connect(SOCKET,$remoteport) or die "connect:$!";

print SOCKET "GET / HTTP/1.0\n\n";


        while ( $buffer = <SOCKET> )
        {

                print $buffer;

        }


select(SOCK); $| = 1; select(STDOUT);




PS: Some time ago I wrote a silly HTTP scanner based upon Perl &
Sockets. My test version is working with LWP library, but you can still
found how I did to manage this at: http://www.sourceforge.net/wanesa/

Cheers!
