I'm trying to hack a site with Perl script. To get the member hash following is what I type in CMD

C:\Perl\Bin\explt.pl dbbxpl.pl www.website.net/forums/member.php?u=4078

dbbxpl.pl is the server.
It returns me with an error saying
Connection failed at C:\Perl\Bin\ exploit.pl line 47.

Could you guys please help me out? I've hacked MD5 hashes before with Perl script (Yeah, i'm a bit of script kiddie ) but could'nt get this to work. The website I'm trying crack uses VB 3.7.
Is there any tutorial to hack VB 3.7?
Thanks.
