Deny ssh access for certain users in Linux

As we all know that opening ssh for all users is not good foe security reasons.

So to deny ssh access for certain users we have to

Just edit sshd_config located under /etc/ssh/  (location can be different depending upon version of linux )

Add the line

DenyUsers username1 username2

save and exit

then restart the service

# /etc/init.d/sshd restart

Now the users username1 and username2 will be denied.
