The install DVD ships with dropbear which is itself quite a capable server and client. "Dropbear can compile to a 110kB" speaks to the level of optimisation and perhaps genius of the author :-)

Setting Up DropBear ssh server

cd /bin
dropbearkey -t rsa -f /etc/dropbear/dropbear_rsa_key
ifconfig eth0 192.168.0.100 netmask 255.255.255.0
route add default gw 192.168.0.1
