I've long wanted a Net::SSH module (one that doesn't just execute the ssh client). So, partly out of desire for such a module, and partly out of interest in SSH, I wrote such a module.

It's not complete by any means. Currently it has the following restrictions (among others that I'm probably forgetting):

• Doesn't accept/add new host keys. The host key (of the host to which you're connecting) must be found in either ~/.ssh/ssh_known_hosts or /etc/ssh_known_hosts
• Supports only password authentication
• Supports only IDEA encryption

What is working? Well, enough that I can do the following:

    use Net::SSH;
    my $ssh = Net::SSH->new($host);
    $ssh->login($user, $pass);
    my($out, $err) = $ssh->cmd($cmd);

If you're interested in trying it out, grab it at http://rhumba.pair.com/ben/perl/Net-SSH-0.01.tar.gz.

The installation is relatively tricky; it's described in the README, but part of the trickiness is because it depends on a module (Crypt::CFB) which doesn't seem to be on CPAN (I bundled it with the tarball), and it requires a patch to Math::GMP (patch included).

I'm going to start working on adding support for some other ciphers and more authentication routines.

I'd really love some feedback on the module, though, so please, if you have a chance, do try it out, and if you have any comments, let me know.
