.SH NAME
urukctl \- uruk control script
.SH SYNOPSIS
\fBurukctl\fP \fIcommand\fP \fB[\fP\fIargument\fP\fB]\fP
.SH DESCRIPTION

\fBurukctl\fP is the user interface for the uruk system\&. It is used to create or
change saved iptables rulesets, to change the current loaded rulesets and to
report on uruk\&'s status\&.

See \fBuruk(8)\fP for information on how to get started with the Uruk
system, and for a tutorial\&. This manpage gives just the details on \fBurukctl\fP\&.

The \fBurukctl\fP script calls \fBuruk\fP to process /etc/uruk/rc\&. (The uruk init script
calls \fBurukctl\fP\&.)

These 4 ruleset pairs (for both IPv4 and IPv6) exist in a system using uruk:

.ZI 2m "\(bu"
\&
.br
the ruleset as expressed in the uruk configuration /etc/uruk/rc,
.in -2m
.ZI 2m "\(bu"
\&
.br
the 2 saved rulesets in \fC/var/lib/{iptables,ip6tables}/{active,inactive}\fP
.in -2m
.ZI 2m "\(bu"
\&
.br
the ruleset as currently loaded in the running kernel
.in -2m
.ZI 2m "\(bu"
\&
.br
optional: more rulesets saved in \fC/var/lib/{iptables,ip6tables}\fP
.in -2m

\fBarguments\fP
.br
\fBurukctl\fP should be called as either \fCurukctl\fP \fIargument\fP or
\fCurukctl\fP \fIargument\fP \fIoption\fP\&. Possible values are:

.ZI 2m "\fBstart\fP"
\&
.br
If not yet done, save current iptables status in "inactive" ruleset\&.
(Re)build and load the "active" ruleset\&.
.in -2m

.ZI 2m "\fBsave\fP \fIruleset\fP"
\&
.br
Save the current iptables status in given ruleset\&.
.in -2m

.ZI 2m "\fBcreate\fP <\fCactive\fP|\fCinactive\fP>"
\&
.br
Create an "active" or "inactive" ruleset with sane defaults: "active"
will be based upon the uruk rc file\&. "inactive" will allow all traffic\&.
.in -2m

.ZI 2m "\fBload\fP \fIruleset\fP"
\&
.br
Load a saved ruleset
.in -2m

.ZI 2m "\fBreload\fP"
\&
.br
(Re)build and load the "active" ruleset, without temporarily clearing the
current iptables status\&.
.in -2m

.ZI 2m "\fBforce-reload\fP"
\&
.br
(Re)build and load the "active" ruleset, in case uruk is running\&.
.in -2m

.ZI 2m "\fBstop\fP"
\&
.br
Load the "inactive" ruleset\&.
.in -2m

.ZI 2m "\fBrestart\fP"
\&
.br
Perform stop-actions followed by start-actions\&.
.in -2m

.ZI 2m "\fBstatus\fP"
\&
.br
Print the current status of the service: show which ruleset is loaded, and
wether uruk is "running"\&.
.in -2m

.ZI 2m "\fBclear\fP"
\&
.br
Remove all rules and user-defined chains, set default policy to ACCEPT\&.
.in -2m

.ZI 2m "\fBhalt\fP"
\&
.br
Remove all rules and user-defined chains, set default policy to DROP\&.
.in -2m

.ZI 2m "\fBflush\fP"
\&
.br
Flush all rules from the current iptables status\&.
.in -2m

\fBconfiguration\fP
.br
\fBurukctl\fP uses the file /etc/default/uruk (on Debian, Ubuntu and related
systems) or /etc/sysconfig/uruk (on Red Hat, Fedora and related systems) for
configuration\&. Variables used in this file are:

.ZI 2m "enable_uruk_check"
\&
.br
wether to check for existence and sanity of uruk rc file; set to false if
you don\&'t like this, e\&.g\&. when using the uruk initscript for managing saved
rulesets only (i\&.e\&. not for calling uruk or uruk-save)\&.
.in -2m

.ZI 2m "enable_ipv6"
\&
.br
set to false to disable IPv6 support\&. Set to \fC$(enable-ipv6)\fP to
dynamically decide wether to filter IPv6 traffic\&.
.in -2m

.ZI 2m "enable_uruk_save"
\&
.br
enable calling the unstable uruk-save script\&.
.in -2m

.ZI 2m "enable_autosave"
\&
.br
set to "false" to disable autosaving the active ruleset when going from
start to stop\&.
.in -2m

.ZI 2m "enable_save_counters"
\&
.br
set to "false" to disable saving table counters with rulesets\&.
.in -2m
