DESCRIPTION
The shorewall-lite utility is used to control the Shoreline Firewall Lite (Shorewall Lite).
OPTIONS
The trace and debug options are used for debugging. See
http://www.shorewall.net/starting_and_stopping_shorewall.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 commands in /etc/shorewall/started.
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. Alternately, 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 host or network addresses.
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-lite 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.
If -f is given, the command will be processed by the compiled script that executed the last
successful start, restart or refresh command if that script exists.
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.
disable
Added in Shorewall 4.4.26. Disables the optional provider associated with the specified interface or
provider. Where more than one provider share a single network interface, a provider name must be
given.
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.
The -l option causes the rule number for each Netfilter rule to be displayed.
enable
Added in Shorewall 4.4.26. Enables the optional provider associated with the specified interface or
provider. Where more than one provider share a single network interface, a provider name must be
given.
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.conf[1](5) is assumed.
help
Displays a syntax summary.
hits
Generates several reports from Shorewall-lite log messages in the current log file. If the -t option
is included, the reports are restricted to log messages generated today.
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.
iptrace
This is a low-level debugging command that causes iptables TRACE log records to be created. See
iptables(8) for details.
The iptables match expression must be one or more matches that may appear in both the raw table
OUTPUT and raw table PREROUTING chains.
The trace records are written to the kernel's log buffer with facility = kernel and priority =
warning, and they are routed from there by your logging daemon (syslogd, rsyslog, syslog-ng, ...) --
Shorewall-lite has no control over where the messages go; consult your logging daemon's
documentation.
logdrop
Causes traffic from the listed addresses to be logged then discarded. Logging occurs at the log level
specified by the BLACKLIST_LOGLEVEL setting in shorewall.conf[1] (5).
logwatch
Monitors the log file specified by the LOGFILE option in shorewall.conf[1](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. Logging occurs at the log level
specified by the BLACKLIST_LOGLEVEL setting in shorewall.conf[1] (5).
noiptrace
This is a low-level debugging command that cancels a trace started by a preceding iptrace command.
The iptables match expression must be one given in the iptrace command being canceled.
reset
All the packet and byte counters in the firewall are reset.
restart
Restart is similar to shorewall-lite start except that it assumes that the firewall is already
started. Existing connections are maintained.
The -n option causes Shorewall-lite 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.conf[1](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. If filename is not given
then the state is saved in the file specified by the RESTOREFILE option in shorewall.conf[1](5).
show
The show command can have a number of different arguments:
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.
The -b ('brief') option causes rules which have not been used (i.e. which have zero packet and
byte counts) to be omitted from the output. Chains with no rules displayed are also omitted from
the output.
The -l option causes the rule number for each Netfilter rule to be displayed.
If the t option and the chain keyword are both omitted and any of the listed chains do not exist,
a usage message is displayed.
classifiers|filters
Displays information about the packet classifiers defined on the system as a result of traffic
shaping configuration.
config
Displays distribution-specific defaults.
connections
Displays the IP connections currently being tracked by the firewall.
event event
Added in Shorewall 4.5.19. Displays the named event.
events
Added in Shorewall 4.5.19. Displays all events.
ip
Displays the system's IPv4 configuration.
ipa
Added in Shorewall 4.4.17. Displays the per-IP accounting counters (shorewall-accounting[3] (5)).
log
Displays the last 20 Shorewall-lite messages from the log file specified by the LOGFILE option in
shorewall.conf[1](5). The -m option causes the MAC address of each packet source to be displayed
if that information is available.
marks
Added in Shorewall 4.4.26. Displays the various fields in packet marks giving the min and max
value (in both decimal and hex) and the applicable mask (in hex).
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.
policies
Added in Shorewall 4.4.4. Displays the applicable policy between each pair of zones. Note that
implicit intrazone ACCEPT policies are not displayed for zones associated with a single network
where that network doesn't specify routeback.
routing
Displays the system's IPv4 routing configuration.
raw
Displays the Netfilter raw table using the command iptables -t raw -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 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.
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[1](5), are taken down. The only new
traffic permitted through the firewall is from systems listed in shorewall-routestopped[4](5) or by
ADMINISABSENTMINDED.
If -f is given, the command will be processed by the compiled script that executed the last
successful start, restart or refresh command if that script exists.
status
Produces a short report about the state of the Shorewall-configured firewall.
version
Displays Shorewall's version. The -a option is included for compatibility with earlier Shorewall
releases and is ignored.
EXIT STATUS
In general, when a command succeeds, status 0 is returned; when the command fails, a non-zero status is
returned.
The status command returns exit status as follows:
0 - Firewall is started.
3 - Firewall is stopped or cleared
4 - Unknown state; usually means that the firewall has never been started.
