<title>OPTIONS</title>
|
|
|
|
|
|
|
|
<para>Many options have as their value a <emphasis>log-level</emphasis>.
|
|
|
|
Log levels are a method of describing to syslog (8) the importance of a
|
|
|
|
message and a number of parameters in this file have log levels as their
|
|
|
|
value.</para>
|
|
|
|
|
|
|
|
<para>These levels are defined by syslog and are used to determine the
|
|
|
|
destination of the messages through entries in /etc/syslog.conf (5). The
|
|
|
|
syslog documentation refers to these as "priorities"; Netfilter calls them
|
2008-12-14 18:37:30 +01:00
|
|
|
"levels" and Shorewall6 also uses that term.</para>
|
2008-12-11 01:03:00 +01:00
|
|
|
|
|
|
|
<para>Valid levels are:</para>
|
|
|
|
|
|
|
|
<programlisting> 7 debug
|
|
|
|
6 info
|
|
|
|
5 notice
|
|
|
|
4 warning
|
|
|
|
3 err
|
|
|
|
2 crit
|
|
|
|
1 alert
|
|
|
|
0 emerg</programlisting>
|
|
|
|
|
2008-12-14 18:37:30 +01:00
|
|
|
<para>For most Shorewall6 logging, a level of 6 (info) is appropriate.
|
|
|
|
Shorewall6 log messages are generated by NetFilter and are logged using
|
2008-12-11 01:03:00 +01:00
|
|
|
facility 'kern' and the level that you specifify. If you are unsure of the
|
|
|
|
level to choose, 6 (info) is a safe bet. You may specify levels by name or
|
|
|
|
by number.</para>
|
|
|
|
|
2008-12-14 21:03:49 +01:00
|
|
|
<para>If you have built your kernel with NFLOG target support, you may
|
|
|
|
also specify a log level of NFLOG (must be all caps). Rather than log its
|
2008-12-14 18:37:30 +01:00
|
|
|
messages to syslogd, Shorewall6 will direct netfilter to log the messages
|
2008-12-14 21:03:49 +01:00
|
|
|
via the NFLOG target which will send them to a process called 'ulogd'.
|
2008-12-11 01:03:00 +01:00
|
|
|
ulogd is available with most Linux distributions (although it probably
|
|
|
|
isn't installed by default). Ulogd is also available from <ulink
|
|
|
|

<para>Beginning in Shorewall 4.4.6, setting this option to 'Yes'
|
|
|
|
also simplifies PREROUTING rules in <ulink

url="shorewall6-tcrules.html">shorewall6-tcrules</ulink>(5).
|
|
|
|
Previously, when TC_EXPERT=No, packets arriving through 'tracked'
|
|
|
|
provider interfaces were unconditionally passed to the PREROUTING
|
|
|
|
tcrules. This was done so that tcrules could reset the packet mark
|
2010-01-14 17:36:22 +01:00
|
|
|
to zero, thus allowing the packet to be routed using the 'main'
|
|
|
|
routing table. Using the main table allowed dynamic routes (such as
|
|
|
|
those added for VPNs) to be effective. The <ulink
|
|
|
|
url="shorewall6-route_rules.html">shorewall6-route_rules</ulink>(5)
|
|
|
|
file was created to provide a better alternative to clearing the
|
|
|
|
packet mark. As a consequence, passing these packets to PREROUTING
|
|
|
|
complicates things without providing any real benefit. Beginning
|
|
|
|
with Shorewall 4.4.6, when TRACK_PROVIDERS=Yes and TC_EXPERT=No,
|
|
|
|
packets arriving through 'tracked' interfaces will not be passed to
|
|
|
|
the PREROUTING rules. Since TRACK_PROVIDERS was just introduced in
|
|
|
|
4.4.3, this change should be transparent to most, if not all,
|
|
|
|
users.</para>
