The shorewall-lite utility is used to control the Shoreline Firewall Lite (Shorewall Lite).
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 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(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 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.
The available commands are listed below.
interface
[:host-list
]...
zone
| zone
host-list
}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(5) file. A host-list is comma-separated list whose elements are host or network addresses.
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.
address
Re-enables receipt of packets from hosts previously blacklisted by a drop, logdrop, reject, or logreject command. Beginning with Shorewall 5.0.10, this command can also re-enable addresses blacklisted using the blacklist command.
address
[ option
... ]Added in Shorewall 5.0.8 and requires
DYNAMIC_BLACKLIST=ipset.. in shorewall.conf(5).
Causes packets from the given host or network
address
to be dropped, based on the
setting of BLACKLIST in shorewall.conf(5). The
address
along with any
option
s are passed to the ipset
add command.
function
[
parameter
... ]Added in Shorewall 4.6.10. Allows you to call a function in one of the Shorewall libraries or in your compiled script. function must name the shell function to be called. The listed parameters are passed to the function.
The function is first searched for in
lib.base
, lib.common
and
lib.cli
. If it is not found, the call command
is passed to the generated script to be executed.
f
]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, reload, restart or refresh command if that script exists.
open-number
|
source
dest
[
protocol
[ port
] ] }Added in Shorewall 4.5.8. This command closes a temporary open
created by the open command. In the first form,
an open-number
specifies the open to be
closed. Open numbers are displayed in the num column of the output of the
shorewall-lite show opens command.
When the second form of the command is used, the parameters must match those given in the earlier open command.
interface
[:host-list
]...
zone
| zone
host-list
}The delete command reverses the effect of an earlier add command.
The interface argument names an interface defined in the shorewall-interfaces(5) file. A host-list is comma-separated list whose elements are a host or network address.
interface
|
provider
}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.
address
Causes traffic from the listed addresses to be silently dropped.
x
]
[-l
] [-m
]
[-c
]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.
The -c
option causes the route cache to be
dumped in addition to the other routing information.
interface
|
provider
}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.
filename
]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(5) is assumed.
Displays a syntax summary.
t
]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 displays the network address, broadcast address, network in CIDR notation and netmask corresponding to the input[s].
address1
-address2
Iprange decomposes the specified range of IP addresses into the equivalent list of network/host addresses.
iptables
match expression
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.
list is a synonym for show -- please see below.
address
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 (5).
m
]
[refresh-interval
]Monitors the log file specified by the LOGFILE option in
shorewall.conf(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.
address
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 (5).
ls is a synonym for show -- please see below.
iptables
match expression
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.
source
dest
[
protocol
[ port
] ]Added in Shorewall 4.6.8. This command requires that the firewall be in the started state and that DYNAMIC_BLACKLIST=Yes in shorewall.conf (5). The effect of the command is to temporarily open the firewall for connections matching the parameters.
The source
and
dest
parameters may each be specified as
all if you don't wish to restrict
the connection source or destination respectively. Otherwise, each
must contain a host or network address or a valid DNS name.
The protocol
may be specified
either as a number or as a name listed in /etc/protocols. The
port
may be specified numerically or as a
name listed in /etc/services.
To reverse the effect of a successful open command, use the close command with the same parameters or simply restart the firewall.
Example: To open the firewall for SSH connections to address 192.168.1.1, the command would be:
shorewall-lite open all 192.168.1.1 tcp 22
To reverse that command, use:
shorewall-lite close all 192.168.1.1 tcp 22
interface
|
provider
}Added in Shorewall 4.6.9. This is equivalent to a
disable command followed by an
enable command on the specified
interface
or
provider
.
address
Causes traffic from the listed addresses to be silently rejected.
C
]Added in Shorewall 5.0.0, reload 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.
The -C
option was added in Shorewall 4.6.5.
If the specified (or implicit) firewall script is the one that
generated the current running configuration, then the running
netfilter configuration will be reloaded as is so as to preserve the
iptables packet and byte counters.
chain
,
...]Resets the packet and byte counters in the specified
chain
(s). If no
chain
is specified, all the packet and
byte counters in the firewall are reset.
C
]Beginning with Shorewall 5.0.0, this command performs a true restart. The firewall is completely stopped as if a stop command had been issued then it is started again.
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.
The -C
option was added in Shorewall 4.6.5.
If the specified (or implicit) firewall script is the one that
generated the current running configuration, then the running
netfilter configuration will be reloaded as is so as to preserve the
iptables packet and byte counters.
n
]
[-p
] [-C
] [
filename
]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(5).
If your iptables ruleset depends on variables that are detected at run-time, either in your params file or by Shorewall-generated code, restore will use the values that were current when the ruleset was saved, which may be different from the current values.
The -n
option causes Shorewall to avoid
updating the routing table(s).
The -p
option, added in Shorewall 4.6.5,
causes the connection tracking table to be flushed; the
conntrack utility must be installed to use this
option.
The -C
option was added in Shorewall 4.6.5.
If the -C
option was specified during shorewall save, then the counters saved by
that operation will be restored.
command
[
parameter
... ]Added in Shorewall 4.6.3. Executes
command
in the context of the generated
script passing the supplied parameter
s.
Normally, the command
will be a function
declared in lib.private
.
Before executing the command
, the
script will detect the configuration, setting all SW_* variables and
will run your init
extension script with
$COMMAND = 'run'.
C
] [
filename
]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(5).
The -C
option, added in Shorewall 4.6.5,
causes the iptables packet and byte counters to be saved along with
the chains and rules.
Added in shorewall 4.6.8. Performs the same action as the stop command with respect to saving ipsets (see the SAVE_IPSETS option in shorewall.conf (5)). This command may be used to proactively save your ipset contents in the event that a system failure occurs prior to issuing a stop command.
The show command can have a number of different arguments:
x
]Added in Shorewall 4.6.2. Displays the dynamic chain along with any chains produced by entries in shorewall-blrules(5).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.
f
] capabilitiesDisplays your kernel/iptables capabilities. The -f option causes the display to be formatted as a capabilities file for use with compile -e.
b
] [-x
]
[-l
] [-t
{filter
|mangle
|nat
|raw
|rawpost
}]
[ 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 chain
s do not exist, a usage
message is displayed.
Displays information about the packet classifiers defined on the system as a result of traffic shaping configuration.
Displays distribution-specific defaults.
filter_parameter
...]Displays the IP connections currently being tracked by the firewall.
If the conntrack utility is installed, beginning with Shorewall 4.6.11 the set of connections displayed can be limited by including conntrack filter parameters (-p , -s, --dport, etc). See conntrack(8) for details.
event
Added in Shorewall 4.5.19. Displays the named event.
Added in Shorewall 4.5.19. Displays all events.
Displays the system's IPv4 configuration.
Added in Shorewall 4.4.17. Displays the per-IP accounting counters (shorewall-accounting (5)).
m
] logDisplays the last 20 Shorewall-lite messages from the log file specified by the LOGFILE option in shorewall.conf(5). The -m option causes the MAC address of each packet source to be displayed if that information is available.
x
] mangleDisplays 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.
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).
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.
Added in Shorewall 4.5.8. Displays the iptables rules in the 'dynamic' chain created through use of the open command..
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
.
Displays the system's IPv4 routing configuration. The -c option causes the route cache to be displayed in addition to the other routing information.
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.
Displays information about queuing disciplines, classes and filters.
Displays the current composition of the Shorewall zones on the system.
p
]
[-n
] [-f
]
[-C
]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.
The -n
option prevents the firewall script
from modifying the current routing configuration.
The -f
option was added in Shorewall 4.6.5.
If the RESTOREFILE named in shorewall.conf(5) exists, is
executable and is not older than the current filewall script, then
that saved configuration is restored.
The -C
option was added in Shorewall 4.6.5
and is only meaningful when the -f
option is also
specified. If the previously-saved configuration is restored, and if
the -C
option was also specified in the save command, then the packet and byte
counters will be restored.
Stops the firewall. All existing connections, except those listed in shorewall-routestopped(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(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.
Produces a short report about the state of the Shorewall-configured firewall.
The -i
option was added in Shorewall 4.6.2
and causes the status of each optional or provider interface to be
displayed.
Displays Shorewall's version. The -a
option
is included for compatibility with earlier Shorewall releases and is
ignored.
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.
Two environmental variables are recognized by Shorewall-lite:
When set to 1, causes Std out to be redirected to the file specified in the STARTUP_LOG option in shorewall.conf(5).
Added in Shorewall 5.0.8. When set to a non-empty value, that value is passed to the logger utility in its -t (--tag) option.
