<para>The <emphasis>options</emphasis> control the amount of output that
|
|
the command produces. They consist of a sequence of the letters <emphasis
|
|
role="bold">v</emphasis> and <emphasis role="bold">q</emphasis>. If the
|
|
options are omitted, the amount of output is determined by the setting of
|
|
the VERBOSITY parameter in shorewall.conf(5). Each <emphasis
|
|
role="bold">v</emphasis> adds one to the effective verbosity and each
|
|
<emphasis role="bold">q</emphasis> subtracts one from the effective
|
|
VERBOSITY.</para>

<para>The <emphasis role="bold">-e</emphasis> option causes the

<para>Clear will remove all rules and chains installed by Shorewall.

system other than where the compiled script will run. This option

disables certain configuration options that require the script to be

compiled where it is to be run. The use of -e requires the presense

of a configuration file named capabilities which may be produced

using the command <emphasis role="bold">shorewall-lite show -f
