hosts.allow not working

["Ranbir Sanasam" <san.ranbir@gmail.com>]

Hi all,

Can anybody help me? I want to allow ssh access only from 10.6.5.215
machine but block from the rest and my hosts.allow and hosts.deny are
as follows.
/etc/hosts.allow
sshd: 10.6.5.215 

and 
/etc/hosts.deny

sshd:  ALL

still i am able to access from other machines.. What could be the problem?
Is there any log entry from hosts.allow or hosts.deny?

I am using Debian Sarge.

thanks
