that contains $[SOME_NAME] will have $[SOME_NAME] substituted with the

DenyHosts v2.1

- added command line flag --sync which runs DenyHosts (command line/cron version)
in synchronization mode.

- added SYNC_DOWNLOAD_RESILIENCY setting to limit download synchronization
data to attacks that have lasted longer than this value. That is, if the centralized
denyhosts.net server records an attack at 2 PM and then again at 5 PM,
specifying a SYNC_DOWNLOAD_RESILIENCY = 4h will not download this ip
address. However, if the attacker is recorded again at 6:15 PM then the ip address
will be downloaded by your DenyHosts instance. This value is used in
conjunction with the SYNC_DOWNLOAD_THRESHOLD and only hosts that
satisfy both values will be downloaded. This value has no effect if
SYNC_DOWNLOAD_THRESHOLD = 1 and refers to the timespan between the
attackers first known attack and their most recent attack.
Refer to http://www.denyhosts.net/faq.html#sync_download_resiliency... read more

DenyHosts 0.9.x is now available

DenyHosts 0.9 and greater offers the ability to run the app as a daemon in addition to the legacy command line mode (aka cron mode). Several new configuration values were added to support the daemon mode. Please view the denyhosts.cfg-dist file for details or check the FAQ:

http://denyhosts.sourceforge.net/faq.html#daemon

There is also a daemon-control-dist script provided with the distribution that allows you to easily start, stop and restart the daemon as well as check the status and change the debug level on the fly. The above FAQ entry also contains information for using the daemon-control-dist script.
