2015-05-09 DenyHosts no longer available on Debian 8.0 Jessie

When I was configuring a new Debian 8.0 ("Jessie") server, I noticed the very useful DenyHosts package is no longer available in the package repository. The package "sshguard" however, is available and according to my testing, works fine.

These packages block an IP address after a number of failed login attempts. This is very useful to counter brute-force attacks on your SSH server.
