hi,

Thank you so much and the tutorials is so good :)

I use Active Perl to compile and execute perl script. Active Perl has pre-insall the PPM, but there is no Net::SSH::Perl module in PPM.

I download the Net::SSH::Perl from CPAN and install it on my Windows platform. But I don't know I should install Math::Pari module. Thank you for you reminder :). I'll install this module and try again.
