DESCRIPTION
The shorewall-lite utility is used to control the Shoreline Firewall
(Shorewall) Lite.
OPTIONS
The trace and debug options are used for debugging. See
http://www.shorewall.net/starting_and_stopping.htm#Trace.
The nolock option prevents the command from attempting to acquire the
Shorewall Lite lockfile. It is useful if you need to include
shorewall-lite commands in the started extension script.
The options control the amount of output that the command produces.
They consist of a sequence of the letters v and q. If the options are
omitted, the amount of output is determined by the setting of the
VERBOSITY parameter in shorewall.conf[1](5). Each v adds one to the
effective verbosity and each q subtracts one from the effective
VERBOSITY. Anternately, v may be followed immediately with one of
-1,0,1,2 to specify a specify VERBOSITY. There may be no white space
between v and the VERBOSITY.
The options may also include the letter t which causes all progress
messages to be timestamped.
COMMANDS
The available commands are listed below.
add
Adds a list of hosts or subnets to a dynamic zone usually used with
VPN's.
The interface argument names an interface defined in the
shorewall-interfaces[2](5) file. A host-list is comma-separated
list whose elements are a host or network address..if n .sp
Caution
The add command is not very robust. If there are errors in the
host-list, you may see a large number of error messages yet a
subsequent shorewall show zones command will indicate that all
hosts were added. If this happens, replace add by delete and
run the same command again. Then enter the correct command.
allow
Re-enables receipt of packets from hosts previously blacklisted by
a drop, logdrop, reject, or logreject command.
clear
Clear will remove all rules and chains installed by Shorewall Lite.
The firewall is then wide open and unprotected. Existing
connections are untouched. Clear is often used to see if the
firewall is causing connection problems.
delete
The delete command reverses the effect of an earlier add command.
The interface argument names an interface defined in the
shorewall-interfaces[2](5) file. A host-list is comma-separated
list whose elements are a host or network address.
drop
Causes traffic from the listed addresses to be silently dropped.
dump
Produces a verbose report about the firewall configuration for the
purpose of problem analysis.
The -x option causes actual packet and byte counts to be displayed.
Without that option, these counts are abbreviated. The -m option
causes any MAC addresses included in Shorewall Lite log messages to
be displayed.
forget
Deletes /var/lib/shorewall-lite/filename and
/var/lib/shorewall-lite/save. If no filename is given then the file
specified by RESTOREFILE in shorewall-lite.conf[3](5) is assumed.
help
Displays a syntax summary.
hits
Generates several reports from Shorewall Lite log messages in the
current log file.
ipcalc
Ipcalc displays the network address, broadcast address, network in
CIDR notation and netmask corresponding to the input[s].
iprange
Iprange decomposes the specified range of IP addresses into the
equivalent list of network/host addresses.
logdrop
Causes traffic from the listed addresses to be logged then
discarded.
logwatch
Monitors the log file specified by theLOGFILE option in
shorewall-lite.conf[3](5) and produces an audible alarm when new
Shorewall Lite messages are logged. The -m option causes the MAC
address of each packet source to be displayed if that information
is available. The refresh-interval specifies the time in seconds
between screen refreshes. You can enter a negative number by
preceding the number with "--" (e.g., shorewall-lite logwatch --
-30). In this case, when a packet count changes, you will be
prompted to hit any key to resume screen refreshes.
logreject
Causes traffic from the listed addresses to be logged then
rejected.
reset
All the packet and byte counters in the firewall are reset.
restart
Restart is similar to shorewall-lite start but assumes that the
firewall is already started. Existing connections are maintained.
The -n option causes Shorewall to avoid updating the routing
table(s).
The -p option causes the connection tracking table to be flushed;
the conntrack utility must be installed to use this option.
restore
Restore Shorewall Lite to a state saved using the shorewall-lite
save command. Existing connections are maintained. The filename
names a restore file in /var/lib/shorewall-lite created using
shorewall-lite save; if no filename is given then Shorewall Lite
will be restored from the file specified by the RESTOREFILE option
in shorewall-lite.conf[3](5).
save
The dynamic blacklist is stored in /var/lib/shorewall-lite/save.
The state of the firewall is stored in
/var/lib/shorewall-lite/filename for use by the shorewall-lite
restore and shorewall-lite -f start commands. If filename is not
given then the state is saved in the file specified by the
RESTOREFILE option in shorewall-lite.conf[3](5).
show
The show command can have a number of different arguments:
actions
Produces a report about the available actions (built-in,
standard and user-defined).
capabilities
Displays your kernel/iptables capabilities. The -f option
causes the display to be formatted as a capabilities file for
use with compile -e.
[ [ chain ] chain ... ]
The rules in each chain are displayed using the iptables -L
chain -n -v command. If no chain is given, all of the chains in
the filter table are displayed. The -x option is passed
directly through to iptables and causes actual packet and byte
counts to be displayed. Without this option, those counts are
abbreviated. The -t option specifies the Netfilter table to
display. The default is filter.
If the t option and the chain keyword are both omitted and any
of the listed chains do not exist, a usage message will be
displayed.
classifiers
Displays information about the packet classifiers defined on
the system 10-080213-8397as a result of traffic shaping
configuration.
config
Dispays distribution-specific defaults.
connections
Displays the IP connections currently being tracked by the
firewall.
mangle
Displays the Netfilter mangle table using the command iptables
-t mangle -L -n -v.The -x option is passed directly through to
iptables and causes actual packet and byte counts to be
displayed. Without this option, those counts are abbreviated.
nat
Displays the Netfilter nat table using the command iptables -t
nat -L -n -v.The -x option is passed directly through to
iptables and causes actual packet and byte counts to be
displayed. Without this option, those counts are abbreviated.
tc
Displays information about queuing disciplines, classes and
filters.
zones
Displays the current composition of the Shorewall Lite zones on
the system.
start
Start shorewall Lite. Existing connections through shorewall-lite
managed interfaces are untouched. New connections will be allowed
only if they are allowed by the firewall rules or policies. If -f
is specified, the saved configuration specified by the RESTOREFILE
option in shorewall-lite.conf[3](5) will be restored if that saved
configuration exists and has been modified more recently than the
files in /etc/shorewall.
The -n option causes Shorewall to avoid updating the routing
table(s).
The -p option causes the connection tracking table to be flushed;
the conntrack utility must be installed to use this option.
stop
Stops the firewall. All existing connections, except those listed
in shorewall-routestopped[4](5) or permitted by the
ADMINISABSENTMINDED option in shorewall.conf(5), are taken down.
The only new traffic permitted through the firewall is from systems
listed in shorewall-routestopped[4](5) or by ADMINISABSENTMINDED.
status
Produces a short report about the state of the Shorewall-configured
firewall.
version
Displays Shorewall-lite's version.
