Do you get the feeling that you maybe forgot something? It hangs because you haven't told it to do anything. Here's an example that I used to ping ftp.cpan.org:
#!/usr/bin/perl
use strict;
use warnings;
use Net::SSH::Perl;
my $host = 'ftp.cpan.org';
my $user = 'anonymous';
my $pass = 'anonymous';
my $cmd = exec("ping", "$host");
my $ssh = Net::SSH::Perl->new($host);
$ssh->login($user, $pass);
my ($stdout, $stderr, $exit) = $ssh->cmd($cmd);
print $stdout, "\n";
I really like this module, and I've to decided to contact the module's author to see if he can use a co-maintainer. It'll work for you, but only if you work for it:).
