NAME

DenyHosts - version: 2.10

DESCRIPTION

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]

--file:

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
