<title>Creating a New Action</title>
|
||||
|
||||
<para>Prior to Shorewall version 1.4.9, rules in
|
||||
<filename>/etc/shorewall/rules</filename> were limited to those defined by
|
||||
Netfilter (ACCEPT, DROP, REJECT, etc.). Beginning with Shorewall version
|
||||
1.4.9, users may use sequences of these elementary operations to define
|
||||
more complex actions.</para>
|
||||
|
||||
<para>To define a new action:</para>
|
||||
|
||||
<orderedlist>
|
||||
<listitem>
|
||||
<para>Add a line to
|
||||
<filename><filename>/etc/shorewall/actions</filename></filename> that
|
||||
names your new action. Action names must be valid shell variable names
|
||||
((must begin with a letter and be composed of letters, digits and
|
||||
underscore characters) as well as valid Netfilter chain names. If you
|
||||
intend to log from the action, the name must have a maximum of 11
|
||||
characters. It is recommended that the name you select for a new
|
||||
action begins with a capital letter; that way, the name won't conflict
|
||||
with a Shorewall-defined chain name.</para>
|
||||
|
||||
<para>Beginning with Shorewall-2.0.0-Beta1, the name of the action may
|
||||
be optionally followed by a colon (<quote>:</quote>) and ACCEPT, DROP
|
||||
or REJECT. When this is done, the named action will become the
|
||||
<emphasis>default action </emphasis>for policies of type ACCEPT, DROP
|
||||
or REJECT respectively. The default action is applied immediately
|
||||
before the policy is enforced (before any logging is done under that
|
||||
policy) and is used mainly to suppress logging of uninteresting
|
||||
traffic which would otherwise clog your logs. The same policy name can
|
||||
appear in multiple actions; the last such action for each policy name
|
||||
is the one which Shorewall will use.</para>
|
||||
|
||||
<para>Shorewall includes pre-defined actions for DROP and REJECT --
|
||||
see below.</para>
|
||||
</listitem>
|
||||
|
||||
<listitem>
|
||||
<para>Once you have defined your new action name (ActionName), then
|
||||
copy /usr/share/shorewall/action.template to
|
||||
<filename>/etc/shorewall/action.ActionName</filename> (for example, if
|
||||
your new action name is <quote>Foo</quote> then copy
|

<filename>/usr/share/shorewall/action.template</filename> to

<filename>/etc/shorewall/action.Foo</filename>).</para>

<para>Columns in the action.template file are as follows:</para>

<listitem>

<para>TARGET - Must be ACCEPT, DROP, REJECT, LOG, CONTINUE, QUEUE or

||||
<<emphasis>action</emphasis>> where
|
||||
<<emphasis>action</emphasis>> is a previously-defined action
|
||||
(that is, it must precede the action being defined in this file in
|
||||
your <filename>/etc/shorewall/actions</filename> file). These actions
|
||||
have the same meaning as they do in the
|
||||
<filename>/etc/shorewall/rules</filename> file (CONTINUE terminates
|
||||
processing of the current action and returns to the point where that
|
||||
action was invoked). The TARGET may optionally be followed by a colon
|
||||
(<quote>:</quote>) and a syslog log level (e.g, REJECT:info or
|
||||
ACCEPT:debugging). This causes the packet to be logged at the
|
||||
specified level. You may also specify ULOG (must be in upper case) as
|
||||
a log level.This will log to the ULOG target for routing to a separate
|
||||
log through use of ulogd (<ulink
|
||||

by IP or MAC address; mac addresses must begin with <quote>~</quote>
|
||||
and must use <quote>-</quote> as a separator.</para>
|
||||
|
||||
<para>Alternatively, clients may be specified by interface name. For
|
||||
example, eth1 specifies a client that communicates with the firewall
|
||||
system through eth1. This may be optionally followed by another colon
|

(<quote>:</quote>) and an IP/MAC/subnet address as described above

(e.g., eth1:192.168.1.5).</para>

<para>The change in Shorewall 2.1.2 has an effect on extension scripts

used with user-defined actions. If you define an action 'acton' and you

have an <filename>/etc/shorewall/acton</filename> script then when that

<para>$CHAIN = the name of the chain where your rules are to be

creates a chain with a slightly different name from the action

itself.</para>

<title>Standard Actions In Shorewall 2.0</title>
|
||||
|
||||
<para>Beginning with Shorewall 2.0.0-Beta1, Shorewall includes a number of
|
||||
pre-defined actions. These defined actions are listed in
|
||||
<filename>/usr/share/shorewall/actions.std</filename>.</para>
|
||||
|
||||
<example>
|
||||
<title>Example of Using a Standard Action</title>
|
||||
|
||||
<para>Suppose that you wish to enable ftp from your local network to
|
||||
your firewall. In <filename>/etc/shorewall/rules</filename>:</para>
|
||||
|
||||
<programlisting>#ACTION SOURCE DEST PROTO ...
|
||||
AllowFTP loc $FW</programlisting>
|
||||
</example>
|
||||
|
||||
<para><filename>/usr/share/shorewall/actions.std</filename> is processed
|
||||
before <filename>/etc/shorewall/actions</filename> and if you have any
|
||||
actions defined with the same name as one in
|
||||
<filename>/usr/share/shorewall/actions.std</filename>, your version in
|
||||
<filename class="directory">/etc/shorewall</filename> will be the one
|
||||
used. So if you wish to modify a standard action, simply copy the
|
||||
associated action file from <filename
|
||||
class="directory">/usr/share/shorewall </filename>to <filename
|
||||
class="directory">/etc/shorewall and modify</filename> it to suit your
|
||||
needs. The next <command>shorewall restart</command> will cause your
|
||||
action to be installed in place of the standard one. In particular, if you
|
||||
want to modify the default actions <quote>Drop</quote> or
|
||||
<quote>Reject</quote>, simply copy <filename>action.Drop</filename> or
|
||||
<filename>Action.Reject</filename> to <filename
|
||||
class="directory">/etc/shorewall</filename> and modify that copy as
|
||||
desired.</para>
|
||||
|
||||
<note>
|
||||
<para>Some of the standard actions are <firstterm>built-in</firstterm>s.
|
||||
This means that there is no corresponding action.* file and that
|
||||
Shorewall constructs the rules for the actions using direct
|
||||
<command>iptables</command> commands. If you need to modify one of these
|
||||
built-in actions, you will need to use the <link
|
||||
linkend="Extension">Extension Script mechanism</link> described below
|
||||
and you will need to give the action a different name.</para>

||||

<section id="Common">
|

<title>Default Actions (Formerly Common Actions)</title>
|
||||
|
||||
<para>Also beginning with Shorewall version 2.2.0-Beta1, when an ACCEPT,
|
||||
DROP or REJECT policy is about to be enforced, a <firstterm>default
|
||||
action</firstterm> can first be invoked. In /etc/shorewall/actions.std are
|
||||
found these two entries:</para>
|
||||
|
||||
<programlisting>Drop:DROP #Default Action for DROP policy
|
||||
Reject:REJECT #Default Action for REJECT policy</programlisting>
|
||||
|
||||
<para>These entries designate the action named <firstterm>Drop</firstterm>
|
||||
as the default action for DROP policies and the default action
|
||||
<firstterm>Reject</firstterm> as the default action for REJECT
|
||||
policies.</para>
|
||||
|
||||
<para>The purpose of default actions is:</para>
|
||||
|
||||
<itemizedlist>
|
||||
<listitem>
|
||||
<para>To avoid filling your log with useless clutter. For example, one
|
||||
of the things that the Drop action does is to silently drop SMB
|
||||
traffic by invoking the <firstterm>DropSMB</firstterm> action.</para>
|
||||
</listitem>
|
||||
|
||||
<listitem>
|
||||
<para>To ensure proper behavior. For example, both the Drop and Reject
|
||||
actions invoke the <firstterm>RejectAuth</firstterm> action to REJECT
|
||||
connection requests on TCP port 113. If these requests are simply
|
||||
dropped, connection timeouts can occur when you connect to a server
|
||||
that uses AUTH identification.</para>
|
||||
</listitem>
|
||||
</itemizedlist>
|
||||
|
||||
<para>It should be stressed that <emphasis role="bold">the default actions
|
||||
do not cause any traffic to be dropped or rejected that isn't about to be
|
||||
dropped or rejected anyway</emphasis> (remember that these actions are
|
||||
invoked just before the connection request is going to be dropped or
|
||||
rejected by policy anyway). Their main function is to avoid log

clutter.</para>
