I have used Net::SSH::Perl with success. The basic functionality worked fine, however when I switched over to trying to use id_dsa files (so that I did not have to rely on storing a password in a file), there were some undocumented quirks with the module. The module has a mailing list on Sourceforge where I got my answers but the undocumented features :) did make it more difficult then it had to be.

So the answer is, Net::SSH::Perl can work for you, though it will take a little work to get where it needs to be...
