To run the server, you need to server keys, this is one-off:
./dropbearkey -t rsa -f dropbear_rsa_host_key
./dropbearkey -t dss -f dropbear_dss_host_key
-./dropbearkey -t ecdsa -f dropbear_dss_host_key
+./dropbearkey -t ecdsa -f dropbear_ecdsa_host_key

./dropbearconvert openssh dropbear /etc/ssh/ssh_host_dsa_key dropbear_dss_host_key
