Install the Net-SSH-W32Perl from: http://www.soulcage.net/ppds. specify ### use Net::SSH::Perl; # comment out use Net::SSH::W32Perl; # wrapper for SSH::Perl $ssh = Net::SSH::W32Perl->new($host); # note the W32 part ! install any missing modules from same source !! PPM install http://www.soulcage.net/ppds/PPDS.58/Math-Pari.ppd install http://www.soulcage.net/ppds/PPDS.58/Crypt-DH.ppd etc...
