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. addAdds 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
start
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 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.
