I posted an example a few months ago about how to get started with this.  It's a little more complicated. But, one benefit is that you're driving the same executable you can execute from the command line. If something doesn't work as expected, you can test directly with the module.

You can also try using SCP, which is yet another secure filte transfer 
protocol.  There is an Net::SCP module, but unfortunately, it's just a 
wrapper around a system call to the scp utility.  It worked when I use 
it.  It's a shame we have to go outside perl for this stuff, though.  If 
Net::SSH::Perl is not the speed bottleneck you're suggesting it might 
be, then I can imagine it would be easy to rewrite Net::SCP using 
Net::SSH::Perl.
