The /etc/hosts.deny file specifies which IP addresses are not permitted to connect to the host. It is intended to be used in conjunction with the /etc/hosts.allow file.
Rationale:
The /etc/hosts.deny file serves as a failsafe so that any host not specified in /etc/hosts.allow is denied access to the server.
Parameter:
[yes/no]
Technical Mechanism:
Create /etc/hosts.deny:
# echo ALL: ALL >> /etc/hosts.deny
