There are two important files in DenyHosts in order to make sure that it runs properly: ''hosts.deny'' and ''hosts.allow''. The location of both of these files can be found in [[This Is Your Brain On Informatics: Common Pathnames|common pathnames]].

This file gives permanent ssh access to a server so that recorded IP addresses in this file will not be listed inside by preventing them from being placed in the hosts.deny file. This file can be used if DenyHosts is glitching and constantly placing your IP address in hosts.deny. The syntax for permanently allowing an IP address to ssh into the server is shown below.
