DESCRIPTION
The shorewall6-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 shorewall6-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 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
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 shorewall6-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 shorewall6-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 shorewall6-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/shorewall6-lite/filename and /var/lib/shorewall6-lite/save. If no filename is given then the file specified by
RESTOREFILE in shorewall6.conf[1](5) is assumed.
help
Displays a syntax summary.
hits
Generates several reports from shorewall6-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 faciility = kernel and priority = warning, and they are routed from there
by your logging daemon (syslogd, rsyslog, syslog-ng, ...) -- shorewall6-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 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-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., shorewall6-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 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.
reset
All the packet and byte counters in the firewall are reset.
restart
Restart is similar to shorewall6-lite start except that it assumes that the firewall is already started. Existing connections are
maintained.
The -n option causes shorewall6-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 shorewall6-lite to a state saved using the shorewall6-lite save command. Existing connections are maintained. The filename
names a restore file in /var/lib/shorewall6-lite created using shorewall6-lite save; if no filename is given then shorewall6-lite will
be restored from the file specified by the RESTOREFILE option in shorewall6.conf[1](5).
save
The dynamic blacklist is stored in /var/lib/shorewall6-lite/save. The state of the firewall is stored in
/var/lib/shorewall6-lite/filename for use by the shorewall6-lite restore. 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:
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 -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 IPv4 configuration.
ipa
Added in Shorewall 4.4.17. Displays the per-IP accounting counters (shorewall-accounting[3] (5)).
log
Displays the last 20 shorewall6-lite 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.
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 shorewall6-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 shorewall6.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.
