knoptm - Daemon in charge to remove firewall rules.
knoptm is a daemon that removes rule entries from the iptables or ipfw
policies to which fwknop has added access rules for legitimate fwknop
PK/SPA clients. This daemon runs in all authentication modes supported
by fwknopd (both port knocking and SPA), and enforces rule timeouts
that defined by the /etc/fwknop/access.conf file.
-c, --config <config-file>
When run as a daemon knoptm references the file
/etc/fwknop/fwknop.conf for various run-time configuration
variables. The path to this file can be changed through the use
of the --config command line option.
Specify the interface that fwknopd sniffs to acquire packet
data. This is used for running interface checks, such as
checking whether the interface has been deleted and recreated
(e.g. ppp restart for a VPN connection). The fwknopd daemon
passes this argument on the knoptm command line.
Allow the user to collect outputs from the knoptm daemon by
writing debug informations to a specific file.
Manually specify the firewall type from the command line.
Display usage information and exit.
Display version information and exit.
Path to the perl modules directory (not usually necessary).
-l, --locale <locale>
Provide a locale setting other than the default "C" locale.
Do not set the locale at all so that the default system locale
Do not generate any log output or emails (fwknop_test.pl uses
Disregard ENABLE_VOLUNTARY_EXITS setting. This way
fwknopd/knoptm is not allowed to be restarted periodically
according to EXIT_INTERVAL.
-O, --Override-config <file>
Override config variable values that are normally read from the
/etc/fwknop/fwknop.conf file with values from the specified
file. Multiple override config files can be given as a comma
knoptm can be run in debug mode with the --debug command line option.
This will disable daemon mode execution, and print verbose information
to the screen on STDERR.
