dropbear ssh server

i prefer dropbear, because it is much smaller and more efficient than openssh.

install dropbear in debian, with
# apt-get install dropbear

this package contains an ssh server called dropbear and an ssh client called dbclient.

ssh keys

(re)generate your keys

# dropbearkey -t dss -s 1024 -f /etc/dropbear/dropbear_dss_host_key
# dropbearkey -t rsa -s 4096 -f /etc/dropbear/dropbear_rsa_host_key
# /etc/init.d/dropbear restart

remember to save both the private keys and the public keys.

dropbear can be configured in /etc/default/dropbear.
