Hiding SSH Host Banner Doesnt work

[bo0od]

Im trying to hide the ability to show my host details from OpenSSH on 
GNU/Linux Debian using this method:

Add the following line to /etc/ssh/sshd_config

DebianBanner no

And restart your SSH daemon: /etc/init.d/ssh restart or service ssh restart

This doent change anything.

Another question why user cant hide SSH info as well? why it needs to be 
publicly visible? (I read that only recompiling would fix that but this 
is pain in the neck)

ThX!
