Another option in addition to all the other good advice you've been 
sent is to use sshd via xinetd and you can restrict access to 
specific IP addresses/ranges, times of day, connection frequeceny and  
the other options listed in "man xinetd.conf".  A typical 
configuration to limit access to the 192.168.1.0 network would look 
something like:

service ssh
{
        disable = no
        socket_type = stream
        type = UNLISTED
        port = 22
        protocol = tcp
        wait = no
        user = root
        server = /usr/sbin/sshd
        server_args = -i -u0
        only_from = 192.168.1.0 
}
