Net::SSH::Perl::Auth::Rhosts performs Rhosts authentication
with a remote sshd server. When you create a new Rhosts auth
object, you give it an $ssh object, which should contain an open
connection to an ssh daemon, as well as any data that the
authentication module needs to proceed. In this case, the
$ssh object must contain the name of the user trying
to open the connection.
Rhosts authentication is fairly simple from a protocol point
of view. However, note that the sshd server will require
your client to be running on a privileged port (below 1024);
this will, in turn, likely require your client to be running
as root. If your client is not running on a privileged port,
the Rhosts authentication request will be denied.
If youre running as root, Net::SSH::Perl should
automatically detect that and try to start up on a privileged
port. If for some reason that isnt happening, take a look at
the Net::SSH::Perl docs.
With that aside, to use Rhosts authentication the client
sends a request to the server to authenticate it, including
the name of the user trying to authenticate. The server uses
its shosts.equiv, hosts.equiv, etc. files to determine
whether the user/host should be allowed access.
