You should add the public key in <b>\$HOME/.ssh/authorized_keys</b> of the VNC/SSH server.
</p>
<p>
You can get it on the client (from configuration files) with:
</p>
<pre>
# dropbearkey -y -f /etc/dropbear/dropbear_dss_host_key | grep ^ssh
</pre>
EOT
	false && if [ -s $1/etc/dropbear/dropbear_dss_host_key ]; then
		echo -e "<p>The DSS public key is<p>\n<pre>"
		dropbearkey -y -f $1/etc/dropbear/dropbear_dss_host_key 2>/dev/null | grep ^ssh
		echo "</pre>"
	fi
	cat <<EOT
or
<pre>
# dropbearkey -y -f /etc/dropbear/dropbear_rsa_host_key | grep ^ssh
</pre>
EOT
	false && if [ -s $1/etc/dropbear/dropbear_rsa_host_key ]; then
		echo -e "<p>The RSA public key is<p>\n<pre>"
		dropbearkey -y -f $1/etc/dropbear/dropbear_rsa_host_key 2>/dev/null | grep ^ssh
		echo "</pre>"
	fi
