question on hosts.allow

[David Banning]

I have been running denyhosts to stop attacks on my ssh port.

The attacks continue after protection is put in place.

Here is what I have in the tail of my /etc/hosts.allow 
as per the installation instructions;
-------------------------
...<snip>
sshd : /etc/hosts.deniedssh : deny
sshd : ALL : allow
-------------------------

and in /etc/hosts.deniedssh I have;

-------------------------
sshd: 82.165.182.220 : deny
sshd: 200.52.90.100 : deny
-------------------------

but I am still receiving attacks from the last IP address. So I am wondering
what program actually -reads- hosts.allow 

May be it has to be reset, or restarted?
