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
/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(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.
The available commands are listed below.
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.
Re-enables receipt of packets from hosts previously blacklisted by a drop, logdrop, reject, or logreject command.
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.
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.
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.
Causes traffic from the listed addresses to be silently dropped.
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.
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.
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.
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].
Iprange decomposes the specified range of IP addresses into the equivalent list of network/host addresses.
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, ...) -- Shorewall-lite has no control over where the messages go; consult your logging daemon's documentation.
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).
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.
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).
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.
All the packet and byte counters in the firewall are reset.
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 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).
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 show command can have a number of different arguments:
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 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.
Dispays distribution-specific defaults.
Displays the IP connections currently being tracked by the firewall.
Displays the system's IPv4 configuration.
Added in Shorewall 4.4.17. Displays the per-IP accounting counters (shorewall-accounting (5)).
Displays 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.
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 4.4.4. 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.
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.
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.
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.
Displays Shorewall's version. The -a
option
is included for compatibility with earlier Shorewall releases and is
ignored.
