DESCRIPTION

       The shorewall6 utility is used to control the Shoreline Firewall 6
       (Shorewall6).

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
       Shorewall6 lockfile. It is useful if you need to include shorewall6
       commands in /etc/shorewall6/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 shorewall6.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
           Added in Shorewall 4.4.21. 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
           shorewall6-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.

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

       check
           Compiles the configuraton in the specified directory and discards
           the compiled output script. If no directory is given, then
           /etc/shorewall6 is assumed.

           The -e option causes the compiler to look for a file named
           capabilities. This file is produced using the command
           shorewall6-lite show -f capabilities > capabilities on a system
           with Shorewall6 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 Shorewall6. 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.

       compile
           Compiles the current configuration into the executable file
           pathname. If a directory is supplied, Shorewall6 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.,
           shorewall6 -v-1 compile -- -) to suppress the 'Compiling...'
           message normally generated by /sbin/shorewall6.

           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
           presense of a configuration file named capabilities which may be
           produced using the command shorewall6-lite show -f capabilities >
           capabilities on a system with Shorewall6 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 -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
           Added in Shorewall 4.4.21. The delete command reverses the effect
           of an earlier add command.

           The interface argument names an interface defined in the
           shorewall6-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 Shorewall6 log messages to be
           displayed.

           The -l option causes the rule number for each Netfilter rule to be
           displayed.

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

           Allows a non-root user to compile a shorewall6 script and stage it
           on a system (provided that the user has access to the system via
           ssh). The command is equivalent to:

                   /sbin/shorewall6 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/shorewall6/filename and /var/lib/shorewall6/save.
           If no filename is given then the file specified by RESTOREFILE in
           shorewall6.conf[1](5) is assumed.

       help
           Displays a syntax summary.

       iptrace
           This is a low-level debugging command that causes iptables TRACE
           log records to be created. See ip6tables(8) for details.

           The ip6tables 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
           faciility = 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 shorewall6 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/shorewall6 compile -e directory directory/firewall &&\
                   scp directory/firewall directory/firewall.conf root@system:/var/lib/shorewall6-lite/ &&\
                   ssh root@system '/sbin/shorewall6-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, Shorewall6 Lite on system is started via
           ssh.

           If -s is specified and the start command succeeds, then the remote
           Shorewall6-lite configuration is saved by executing shorewall6-lite
           save via ssh.

           if -c is included, the command shorewall6-lite show capabilities -f
           > /var/lib/shorewall6-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".

       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 shorewall6.conf[1] (5).

       logwatch
           Monitors the log file specified by the LOGFILE option in
           shorewall6.conf[1](5) and produces an audible alarm when new
           Shorewall6 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., shorewall6 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 shorewall6.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 cancelled.

       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.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/shorewall6/tcrulesand install the changes using
           refresh.

           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.

           Example:

               shorewall6 refresh net2fw nat:net_dnat #Refresh the 'net2loc' chain in the filter table and the 'net_dnat' chain in the nat table

       reload
           If directory is omitted, the current working directory is assumed.
           Allows a non-root user to compile a shorewall6 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/shorewall6 compile -e directory directory/firewall &&\
                   scp directory/firewall directory/firewall.conf root@system:/var/lib/shorewall6-lite/ &&\
                   ssh root@system '/sbin/shorewall6-lite restart'

           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, Shorewall6 Lite on system is restarted
           via ssh.

           If -s is specified and the restart command succeeds, then the
           remote Shorewall6-lite configuration is saved by executing
           shorewall6-lite save via ssh.

           if -c is included, the command shorewall6-lite show capabilities -f
           > /var/lib/shorewall6-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".

       reset [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.

       restart
           Restart is similar to shorewall6 start except that it assumes that
           the firewall is already started. Existing connections are
           maintained. If a directory is included in the command, Shorewall6
           will look in that directory first for configuration files.

           The -n option causes Shorewall6 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/shorewall6 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 shorewall6.conf[1](5). When both -f and -c are present, the
           result is determined by the option that appears last.

       restore
           Restore Shorewall6 to a state saved using the shorewall6 save
           command. Existing connections are maintained. The filename names a
           restore file in /var/lib/shorewall6 created using shorewall6 save;
           if no filename is given then Shorewall6 will be restored from the
           file specified by the RESTOREFILE option in shorewall6.conf[1](5).

       safe-restart
           Only allowed if Shorewall6 is running. The current configuration is
           saved in /var/lib/shorewall6/safe-restart (see the save command
           below) then a shorewall6 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 Shorewall6 will look
           in that directory first when opening configuration files.

       safe-start
           Shorewall6 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 shorewall6 clear is
           performed for you. If a directory is given, then Shorewall6 will
           look in that directory first when opening configuration files.

       save
           The dynamic blacklist is stored in /var/lib/shorewall6/save. The
           state of the firewall is stored in /var/lib/shorewall6/filename for
           use by the shorewall6 restore and shorewall6 -f start commands. If
           filename is not given then the state is saved in the file specified
           by the RESTOREFILE option in shorewall6.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/ip6tables 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 ip6tables -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 ip6tables 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 -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
               Dispays distribution-specific defaults.

           connections
               Displays the IP connections currently being tracked by the
               firewall.

           ip
               Displays the system's IPv6 configuration.

           log
               Displays the last 20 Shorewall6 messages from the log file
               specified by the LOGFILE option in shorewall6.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.

           mangle
               Displays the Netfilter mangle table using the command ip6tables
               -t mangle -L -n -v.The -x option is passed directly through to
               ip6tables 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 IPv6 routing configuration.

           tc
               Displays information about queuing disciplines, classes and
               filters.

           zones
               Displays the current composition of the Shorewall6 zones on the
               system.

       start
           Start shorewall6. Existing connections through shorewall6 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, Shorewall6 will look in that directory
           first for configuration files. If -f is specified, the saved
           configuration specified by the RESTOREFILE option in
           shorewall6.conf[1](5) will be restored if that saved configuration
           exists and has been modified more recently than the files in
           /etc/shorewall6. When -f is given, a directory may not be
           specified.

           Update: In Shorewall6 4.4.20, a new LEGACY_FASTSTART option was
           added to shorewall6.conf[1](5). When LEGACY_FASTSTART=No, the
           modificaiotn times of files in /etc/shorewall6 are compared with
           that of /var/lib/shorewall6/firewall (the compiled script that last
           started/restarted the firewall).

           The -n option causes Shorewall6 to avoid updating the routing
           table(s).

           The -c option was added in Shorewall 4.4.20 and performs the
           compilation step unconditionally, overriding the AUTOMAKE setting
           in shorewall6.conf[1](5). When both -f and -c are present, the
           result is determined by the option that appears last.

       stop
           Stops the firewall. All existing connections, except those listed
           in shorewall6-routestopped[3](5) or permitted by the
           ADMINISABSENTMINDED option in shorewall6.conf[1](5), are taken
           down. The only new traffic permitted through the firewall is from
           systems listed in shorewall6-routestopped[3](5) or by
           ADMINISABSENTMINDED.

       status
           Produces a short report about the state of the
           Shorewall6-configured firewall.

       try
           If Shorewall6 is started then the firewall state is saved to a
           temporary saved configuration (/var/lib/shorewall6/.try). Next, if
           Shorewall6 is currently started then a restart command is issued;
           otherwise, a start command is performed. if an error occurs during
           the compliation phase of the restart or start, the command
           terminates without changing the Shorewall6 state. If an error
           occurs during the restart phase, then a shorewall6 restore is
           performed using the saved configuration. If an error occurs during
           the start phase, then Shorewall6 is cleared. If the start/restart
           succeeds and a timeout is specified then a clear or restore is
           performed after timeout seconds.

       update
           Added in Shorewall 4.4.21 and causes the compiler to update
           /etc/shorewall6/shorewall6.conf then validate the configuration.
           The update will add options not present in the existing 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 shorewall6.conf file is renamed
           shorewall6.conf.bak.

           The -a option causes the updated shorewall6.conf file to be
           annotated with documentation.

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

       version
           Displays Shorewall6's version. If the -a option is included, the
           version of Shorewall will also be displayed.
