|
<para>The <option>trace</option> and <option>debug</option> options are
|
|
used for debugging. See <ulink

url="http://www.shorewall.net/starting_and_stopping_shorewall.htm#Trace">http://www.shorewall.net/starting_and_stopping_shorewall.htm#Trace</ulink>.</para>
|
|
|
|
<para>The nolock <option>option</option> prevents the command from
|
|
attempting to acquire the Shorewall-lite lockfile. It is useful if you
|
|
need to include <command>shorewall</command> commands in
|
|
<filename>/etc/shorewall/started</filename>.</para>
|
|
|
|
<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 <ulink
|
|
url="shorewall.conf.html">shorewall.conf</ulink>(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. Alternately, <emphasis role="bold">v</emphasis> may be followed
|
|
immediately with one of -1,0,1,2 to specify a specify VERBOSITY. There may
