DESCRIPTION

       The shorewall utility is used to control the Shoreline Firewall (Shorewall).

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 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.
       Alternatively, 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..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.

Beginning with Shorewall 4.5.9, the dynamic_shared zone option (shorewall-zones[3](5))
allows a single ipset to handle entries for multiple interfaces. When that option is
specified for a zone, the add command has the alternative syntax in which the zone
name precedes the host-list.

allow
Re-enables receipt of packets from hosts previously blacklisted by a drop, logdrop,
reject, or logreject command.

check
Compiles the configuration in the specified directory and discards the compiled output
script. If no directory is given, then /etc/shorewall is assumed.

The -e option causes the compiler to look for a file named capabilities. This file is
produced using the command shorewall-lite show -f capabilities > capabilities on a
system with Shorewall Lite installed.

The -d option causes the compiler to be run under control of the Perl debugger.

The -p option causes the compiler to be profiled via the Perl -wd:DProf command-line
option.

The -r option was added in Shorewall 4.5.2 and causes the compiler to print the
generated ruleset to standard out.

The -T option was added in Shorewall 4.4.20 and causes a Perl stack trace to be
included with each compiler-generated error and warning message.

clear
Clear will remove all rules and chains installed by Shorewall. 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.

compile
Compiles the current configuration into the executable file pathname. If a directory
is supplied, Shorewall will look in that directory first for configuration files. If
the pathname is omitted, the file firewall in the VARDIR (normally
/var/lib/shorewall/) is assumed. A pathname of '-' causes the compiler to send the
generated script to it's standard output file. Note that '-v-1' is usually specified
in this case (e.g., shorewall -v-1 compile -- -) to suppress the 'Compiling...'
message normally generated by /sbin/shorewall.

When -e is specified, the compilation is being performed on a system other than where
the compiled script will run. This option disables certain configuration options that
require the script to be compiled where it is to be run. The use of -e requires the
presence of a configuration file named capabilities which may be produced using the
command shorewall-lite show -f capabilities > capabilities on a system with Shorewall
Lite installed

The -c option was added in Shorewall 4.5.17 and causes conditional compilation of a
script. The script specified by pathname (or implied if pathname is omitted) is
compiled if it doesn't exist or if there is any file in the directory or in a
directory on the CONFIG_PATH that has a modification time later than the file to be
compiled. When no compilation is needed, a message is issued and an exit status of
zero is returned.

The -d option causes the compiler to be run under control of the Perl debugger.

The -p option causes the compiler to be profiled via the Perl -wd:DProf command-line
option.

The -T option was added in Shorewall 4.4.20 and causes a Perl stack trace to be
included with each compiler-generated error and warning message.

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.

Beginning with Shorewall 4.5.9, the dynamic_shared zone option (shorewall-zones[3](5))
allows a single ipset to handle entries for multiple interfaces. When that option is
specified for a zone, the delete command has the alternative syntax in which the zone
name precedes the host-list.

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.

Beginning with Shorewall 4.5.10, this command may be used with any optional network
interface. interface may be either the logical or physical name of the interface. The
command removes any routes added from shorewall-routes[4](5) and any traffic shaping
configuration for the interface.

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 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.

Beginning with Shorewall 4.5.10, this command may be used with any optional network
interface. interface may be either the logical or physical name of the interface. The
command sets /proc entries for the interface, adds any route specified in
shorewall-routes[4](5) and installs the interface's traffic shaping configuration, if
any.

export
If directory1 is omitted, the current working directory is assumed.

Allows a non-root user to compile a shorewall script and stage it on a system
(provided that the user has access to the system via ssh). The command is equivalent
to:

/sbin/shorewall compile -e directory1 directory1/firewall &&\
scp directory1/firewall directory1/firewall.conf [user@]system:[directory2]

In other words, the configuration in the specified (or defaulted) directory is
compiled to a file called firewall in that directory. If compilation succeeds, then
firewall and firewall.conf are copied to system using scp.

forget
Deletes /var/lib/shorewall/filename and /var/lib/shorewall/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 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 has no control over where the messages go;
consult your logging daemon's documentation.

load
If directory is omitted, the current working directory is assumed. Allows a non-root
user to compile a shorewall script and install it on a system (provided that the user
has root access to the system via ssh). The command is equivalent to:

/sbin/shorewall compile -e directory directory/firewall &&\
scp directory/firewall directory/firewall.conf root@system:/var/lib/shorewall-lite/ &&\
ssh root@system '/sbin/shorewall-lite start'

In other words, the configuration in the specified (or defaulted) directory is
compiled to a file called firewall in that directory. If compilation succeeds, then
firewall is copied to system using scp. If the copy succeeds, Shorewall Lite on system
is started via ssh.

If -s is specified and the start command succeeds, then the remote Shorewall-lite
configuration is saved by executing shorewall-lite save via ssh.

if -c is included, the command shorewall-lite show capabilities -f >
/var/lib/shorewall-lite/capabilities is executed via ssh then the generated file is
copied to directory using scp. This step is performed before the configuration is
compiled.

If -r is included, it specifies that the root user on system is named root-user-name
rather than "root".

The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
included with each compiler-generated error and warning message.

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 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 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.

refresh
All steps performed by restart are performed by refresh with the exception that
refresh only recreates the chains specified in the command while restart recreates the
entire Netfilter ruleset. If no chain is given, the static blacklisting chain blacklst
is assumed.

The listed chains are assumed to be in the filter table. You can refresh chains in
other tables by prefixing the chain name with the table name followed by ":" (e.g.,
nat:net_dnat). Chain names which follow are assumed to be in that table until the end
of the list or until an entry in the list names another table. Built-in chains such as
FORWARD may not be refreshed.

The -n option was added in Shorewall 4.5.3 causes Shorewall to avoid updating the
routing table(s).

The -d option was added in Shorewall 4.5.3 causes the compiler to run under the Perl
debugger.

The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
included with each compiler-generated error and warning message.

The -D option was added in Shorewall 4.5.3 and causes Shorewall to look in the given
directory first for configuration files.

Example:

shorewall refresh net2fw nat:net_dnat #Refresh the 'net2loc' chain in the filter table and the 'net_dnat' chain in the nat table

The refresh command has slightly different behavior. When no chain name is given to
the refresh command, the mangle table is refreshed along with the blacklist chain (if
any). This allows you to modify /etc/shorewall/tcrulesand install the changes using
refresh.

reload
If directory is omitted, the current working directory is assumed. Allows a non-root
user to compile a shorewall script and install it on a system (provided that the user
has root access to the system via ssh). The command is equivalent to:

/sbin/shorewall compile -e directory directory/firewall &&\
scp directory/firewall directory/firewall.conf root@system:/var/lib/shorewall-lite/ &&\
ssh root@system '/sbin/shorewall-lite restart'

If -s is specified and the restart command succeeds, then the remote Shorewall-lite
configuration is saved by executing shorewall-lite save via ssh.

If -r is included, it specifies that the root user on system is named root-user-name
rather than "root".

The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
included with each compiler-generated error and warning message.

reset
All the packet and byte counters in the firewall are reset.

restart
Restart is similar to shorewall start except that it assumes that the firewall is
already started. Existing connections are maintained. If a directory is included in
the command, Shorewall will look in that directory first for configuration files.

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.

The -d option causes the compiler to run under the Perl debugger.

The -f option suppresses the compilation step and simply reused the compiled script
which last started/restarted Shorewall, provided that /etc/shorewall and its contents
have not been modified since the last start/restart.

The -c option was added in Shorewall 4.4.20 and performs the compilation step
unconditionally, overriding the AUTOMAKE setting in shorewall.conf[1](5). When both -f
and -care present, the result is determined by the option that appears last.

The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
included with each compiler-generated error and warning message.

restore
Restore Shorewall to a state saved using the shorewall save command. Existing
connections are maintained. The filename names a restore file in /var/lib/shorewall
created using shorewall save; if no filename is given then Shorewall will be restored
from the file specified by the RESTOREFILE option in shorewall.conf[1](5).

safe-restart
Only allowed if Shorewall is running. The current configuration is saved in
/var/lib/shorewall/safe-restart (see the save command below) then a shorewall restart
is done. You will then be prompted asking if you want to accept the new configuration
or not. If you answer "n" or if you fail to answer within 60 seconds (such as when
your new configuration has disabled communication with your terminal), the
configuration is restored from the saved configuration. If a directory is given, then
Shorewall will look in that directory first when opening configuration files.

Beginning with Shorewall 4.5.0, you may specify a different timeout value using the -t
option. The numeric timeout may optionally be followed by an s, m or h suffix (e.g.,
5m) to specify seconds, minutes or hours respectively. If the suffix is omitted,
seconds is assumed.

safe-start
Shorewall is started normally. You will then be prompted asking if everything went all
right. If you answer "n" or if you fail to answer within 60 seconds (such as when your
new configuration has disabled communication with your terminal), a shorewall clear is
performed for you. If a directory is given, then Shorewall will look in that directory
first when opening configuration files.

save
The dynamic blacklist is stored in /var/lib/shorewall/save. The state of the firewall
is stored in /var/lib/shorewall/filename for use by the shorewall restore and
shorewall -f start commands. 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:

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.

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[5] (5)).

log
Displays the last 20 Shorewall 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.

macros
Displays information about each macro defined on the firewall system.

macro
Added in Shorewall 4.4.6. Displays the file that implements the specified macro
(usually /usr/share/shorewall/macro.macro).

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. Existing connections through shorewall managed interfaces are
untouched. New connections will be allowed only if they are allowed by the firewall
rules or policies. If a directory is included in the command, Shorewall will look in
that directory first for configuration files. If -f is specified, the saved
configuration specified by the RESTOREFILE option in shorewall.conf[1](5) will be
restored if that saved configuration exists and has been modified more recently than
the files in /etc/shorewall. When -f is given, a directory may not be specified.

Update: In Shorewall 4.4.20, a new LEGACY_FASTSTART option was added to
shorewall.conf[1](5). When LEGACY_FASTSTART=No, the modification times of files in
/etc/shorewall are compared with that of /var/lib/shorewall/firewall (the compiled
script that last started/restarted the firewall).

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.

The -T option was added in Shorewall 4.5.3 and causes a Perl stack trace to be
included with each compiler-generated error and warning message.

stop
Stops the firewall. All existing connections, except those listed in
shorewall-routestopped[6](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[6](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.

try
If Shorewall is started then the firewall state is saved to a temporary saved
configuration (/var/lib/shorewall/.try). Next, if Shorewall is currently started then
a restart command is issued using the specified configuration directory; otherwise, a
start command is performed using the specified configuration directory. if an error
occurs during the compilation phase of the restart or start, the command terminates
without changing the Shorewall state. If an error occurs during the restart phase,
then a shorewall restore is performed using the saved configuration. If an error
occurs during the start phase, then Shorewall is cleared. If the start/restart
succeeds and a timeout is specified then a clear or restore is performed after timeout
seconds.

Beginning with Shorewall 4.5.0, the numeric timeout may optionally be followed by an
s, m or h suffix (e.g., 5m) to specify seconds, minutes or hours respectively. If the
suffix is omitted, seconds is assumed.

update
Added in Shorewall 4.4.21 and causes the compiler to update
/etc/shorewall/shorewall.conf then validate the configuration. The update will add
options not present in the old file with their default values, and will move
deprecated options with non-defaults to a deprecated options section at the bottom of
the file. Your existing shorewall.conf file is renamed shorewall.conf.bak.

The -a option causes the updated shorewall.conf file to be annotated with
documentation.

The -b option was added in Shorewall 4.4.26 and causes legacy blacklisting rules
(shorewall-blacklist[7] (5) ) to be converted to entries in the blrules file
(shorewall-blrules[8] (5) ). The blacklist keyword is removed from shorewall-zones[3]
(5), shorewall-interfaces[2] (5) and shorewall-hosts[9] (5). The unmodified files are
saved with a .bak suffix.

The -D option was added in Shorewall 4.5.11. When this option is specified, the
compiler will walk through the directories in the CONFIG_PATH replacing FORMAT and
COMMENT entries to compiler directives (e.g., ?FORMAT and ?COMMENT. When a file is
updated, the original is saved in a .bak file in the same directory.

For a description of the other options, see the check command above.

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.
