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

=== hosts.deny ===

This file stores the IP addresses that have been denied access to the server through ssh. If the server is active, this file will fill up rapidly. The importance of this file lies in the fact that it will also deny your IP address if you attempt to unsuccessfully log into the server more than the set number of times (this can also occur if DenyHosts is glitching). If this is the case, open the file on the actual server (through the virtual machine if that is how the server was built) and delete the appropriate IP address. Then reboot the machine.

=== hosts.allow ===
