The default Debian installation turns off X11 forwarding. Edit the
file /etc/ssh/sshd_config and make the change so it has the line

X11Forwarding yes

in it.

The default Debian X11 installation also configures X so that it will
ensure that your attempt to use xhost will fail. But once you have
X11Forwarding set up this does not matter.
