denyhosts man page
DenyHosts — version: 2.10
DenyHosts is a python program that automatically blocks ssh attacks by adding entries to /etc/hosts.deny. DenyHosts will also inform system administrators about offending hosts, attacked users and suspicious logins.
Usage: /usr/sbin/denyhosts [-f logfile | --file=logfile] [ -c configfile | --config=configfile] [-i | --ignore] [-n | --noemail] [--purge] [--migrate] [--daemon] [--sync] [--version]
The name of log file to parse
--config: The configuration file to use, typically /etc/denyhosts.conf
--ignore: Ignore last processed offset (start processing from beginning)
--noemail: Do not send an email report
--unlock: if lockfile exists, remove it and run as normal
--migrate: migrate your HOSTS_DENY file so that it is suitable for --purge
--purge: expire entries older than your PURGE_DENY setting
--purge-all: expire all entries immediately
--purgeip: remove specified IP address from blocked list
--daemon: run DenyHosts in daemon mode
--foreground: run DenyHosts in foreground mode
--sync: run DenyHosts synchronization mode
--version: Prints the version of DenyHosts and exits
Note: multiple --file args can be processed. If multiple files are provided, --ignore is implied
Note: in a Debian system, the default running mode is daemon mode and the configuration file is /etc/denyhosts.conf
When run in --daemon mode the following flags are ignored
--file, --purge, --migrate, --sync, --verbose
