|
<para>The blacklist file is used to perform static blacklisting. You can
|
|
blacklist by source address (IP or MAC), or by application.</para>
|
|
|
|
<para>The columns in the file are as follows.</para>
|
|
|
|
<variablelist>
|
|
<varlistentry>
|
|
<term><emphasis role="bold">ADDRESS/SUBNET</emphasis></term>
|
|
|
|
<listitem>
|
|
<para>Host address, network address, MAC address, IP address range
|
|
(if your kernel and iptables contain iprange match support) or ipset
|
|
name prefaced by "+" (if your kernel supports ipset match).</para>
|
|
|
|
<para>MAC addresses must be prefixed with "~" and use "-" as a
|
|
separator.</para>
|
|
|
|
<para>Example: ~00-A0-C9-15-39-78</para>
|
|
|
|
<para>A dash ("-") in this column means that any source address will
|
|
match. This is useful if you want to blacklist a particular
|
|
application.</para>

<para>When a packet arrives on an interface that has the <emphasis
|
|
role="bold">blacklist</emphasis> option specified in
|
|
shorewall-interfaces(5), its source IP address and MAC address is checked
|
|
against this file and disposed of according to the <emphasis
|
|
role="bold">BLACKLIST_DISPOSITION</emphasis> and <emphasis
|
|
role="bold">BLACKLIST_LOGLEVEL</emphasis> variables in shorewall.conf(5).
|
|
If <emphasis role="bold">PROTOCOL</emphasis> or <emphasis
|
|
role="bold">PROTOCOL</emphasis> and <emphasis role="bold">PORTS</emphasis>
|
|
are supplied, only packets matching the protocol (and one of the ports if
|
|
<emphasis role="bold">PORTS</emphasis> supplied) are blocked.</para>
