One problem is that toto.homeip.net is resolving to 10.0.0.2, which
is a private address that you can't contact from the outside.  Try
doing an ssh from outside, to the numeric public IP address of your
ADSL connection. (You can find this from your router, or by visiting
http://www.whatismyip.com/ from a machine on your LAN.)
If that works, you have a DNS problem unrelated to SSH.
If not, see if you can SSH from another machine on your LAN.  If
so, you have a router configuration problem.  If not, see if
the sshd service is running.
