.SH "DESCRIPTION"
.PP
The shorewall6\-lite utility is used to control the Shoreline Firewall Lite (Shorewall Lite)\&.
.SH "OPTIONS"
.PP
The
\fBtrace\fR
and
\fBdebug\fR
options are used for debugging\&. See
\m[blue]\fBhttp://www\&.shorewall\&.net/starting_and_stopping_shorewall\&.htm#Trace\fR\m[]\&.
.PP
The
\fBnolock\fR
option prevents the command from attempting to acquire the shorewall6\-lite lockfile\&. It is useful if you need to include
\fBshorewall\fR
commands in the
started\m[blue]\fBextension script\fR\m[]\&\s-2\u[1]\d\s+2\&.
.PP
The
\fIoptions\fR
control the amount of output that the command produces\&. They consist of a sequence of the letters
\fBv\fR
and
\fBq\fR\&. If the options are omitted, the amount of output is determined by the setting of the VERBOSITY parameter in
\m[blue]\fBshorewall6\&.conf\fR\m[]\&\s-2\u[2]\d\s+2(5)\&. Each
\fBv\fR
adds one to the effective verbosity and each
\fBq\fR
subtracts one from the effective VERBOSITY\&. Alternately,
\fBv\fR
may be followed immediately with one of \-1,0,1,2 to specify VERBOSITY\&. There may be no white\-space between
\fBv\fR
and the VERBOSITY\&.
.PP
The
\fIoptions\fR
may also include the letter
\fBt\fR
which causes all progress messages to be timestamped\&.
.SH "COMMANDS"
.PP
The available commands are listed below\&.
.PP
\fBadd \fR{ \fIinterface\fR[:\fIhost\-list\fR]\&.\&.\&. \fIzone\fR | \fIzone\fR \fIhost\-list\fR }
.RS 4
Adds a list of hosts or subnets to a dynamic zone usually used with VPN\*(Aqs\&.
.sp
The
\fIinterface\fR
argument names an interface defined in the
\m[blue]\fBshorewall\-interfaces\fR\m[]\&\s-2\u[3]\d\s+2(5) file\&. A
\fIhost\-list\fR
is comma\-separated list whose elements are host or network addresses\&.
.if n \{\
.sp
.\}
.RS 4
.it 1 an-trap
.nr an-no-space-flag 1
.nr an-break-flag 1
.br
.ps +1
\fBCaution\fR
.ps -1
.br
The
\fBadd\fR
command is not very robust\&. If there are errors in the
\fIhost\-list\fR, you may see a large number of error messages yet a subsequent
\fBshorewall6\-lite show zones\fR
command will indicate that all hosts were added\&. If this happens, replace
\fBadd\fR
by
\fBdelete\fR
and run the same command again\&. Then enter the correct command\&.
.sp .5v
.RE
.RE
.PP
\fBallow \fR\fIaddress\fR
.RS 4
Re\-enables receipt of packets from hosts previously blacklisted by a
\fBdrop\fR,
\fBlogdrop\fR,
\fBreject\fR, or
\fBlogreject\fR
command\&. Beginning with Shorewall 5\&.0\&.10, this command can also re\-enable addresses blacklisted using the
\fBblacklist\fR
command\&.
.RE
.PP
\fBblacklist\fR \fIaddress\fR [ \fIoption\fR \&.\&.\&. ]
.RS 4
Added in Shorewall 5\&.0\&.8 and requires DYNAMIC_BLACKLIST=ipset\&.\&. in
\m[blue]\fBshorewall6\&.conf\fR\m[]\&\s-2\u[4]\d\s+2(5)\&. Causes packets from the given host or network
\fIaddress\fR
to be dropped, based on the setting of BLACKLIST in
\m[blue]\fBshorewall6\&.conf\fR\m[]\&\s-2\u[4]\d\s+2(5)\&. The
\fIaddress\fR
along with any
\fIoption\fRs are passed to the
\fBipset add\fR
command\&.
.sp
If the
\fBdisconnect\fR
option is specified in the DYNAMIC_BLACKLISTING setting, then the effective VERBOSITY determines the amount of information displayed:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If the effective verbosity is > 0, then a message giving the number of conntrack flows deleted by the command is displayed\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If the effective verbosity is > 1, then the conntrack table entries deleted by the command are also displayed\&.
.RE
.RE
.PP
\fBcall \fR\fB\fIfunction\fR\fR\fB [ \fR\fB\fIparameter\fR\fR\fB \&.\&.\&. ]\fR
.RS 4
Added in Shorewall 4\&.6\&.10\&. Allows you to call a function in one of the Shorewall libraries or in your compiled script\&. function must name the shell function to be called\&. The listed parameters are passed to the function\&.
.sp
The function is first searched for in
lib\&.base,
lib\&.common
and
lib\&.cli\&. If it is not found, the call command is passed to the generated script to be executed\&.
.RE
.PP
\fBclear \fR\fB \fR[\-\fBf\fR]
.RS 4
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\&.
.sp
If
\fB\-f\fR
is given, the command will be processed by the compiled script that executed the last successful
\fBstart\fR,
\fBreload\fR,
\fBrestart\fR
or
\fBrefresh\fR
command if that script exists\&.
.RE
.PP
\fBclose\fR { \fIopen\-number\fR | \fIsource\fR \fIdest\fR [ \fIprotocol\fR [ \fIport\fR ] ] }
.RS 4
Added in Shorewall 4\&.5\&.8\&. This command closes a temporary open created by the
\fBopen\fR
command\&. In the first form, an
\fIopen\-number\fR
specifies the open to be closed\&. Open numbers are displayed in the
\fBnum\fR
column of the output of the
\fBshorewall6\-lite show opens \fRcommand\&.
.sp
When the second form of the command is used, the parameters must match those given in the earlier
\fBopen\fR
command\&.
.RE
.PP
\fBdelete \fR{ \fIinterface\fR[:\fIhost\-list\fR]\&.\&.\&. \fIzone\fR | \fIzone\fR \fIhost\-list\fR }
.RS 4
The delete command reverses the effect of an earlier
\fBadd\fR
command\&.
.sp
The
\fIinterface\fR
argument names an interface defined in the
\m[blue]\fBshorewall\-interfaces\fR\m[]\&\s-2\u[3]\d\s+2(5) file\&. A
\fIhost\-list\fR
is comma\-separated list whose elements are a host or network address\&.
.RE
.PP
\fBdisable \fR{ \fIinterface\fR | \fIprovider\fR }
.RS 4
Added in Shorewall 4\&.4\&.26\&. Disables the optional provider associated with the specified
\fIinterface\fR
or
\fIprovider\fR\&. Where more than one provider share a single network interface, a
\fIprovider\fR
name must be given\&.
.RE
.PP
\fBdrop \fR\fIaddress\fR
.RS 4
Causes traffic from the listed
\fIaddress\fRes to be silently dropped\&.
.RE
.PP
\fBdump \fR[\-\fBx\fR] [\-\fBl\fR] [\-\fBm\fR] [\-\fBc\fR]
.RS 4
Produces a verbose report about the firewall configuration for the purpose of problem analysis\&.
.sp
The
\fB\-x\fR
option causes actual packet and byte counts to be displayed\&. Without that option, these counts are abbreviated\&.
.sp
The
\fB\-m\fR
option causes any MAC addresses included in shorewall6\-lite log messages to be displayed\&.
.sp
The
\fB\-l\fR
option causes the rule number for each Netfilter rule to be displayed\&.
.sp
The
\fB\-c\fR
option causes the route cache to be dumped in addition to the other routing information\&.
.RE
.PP
\fBenable \fR{ \fIinterface\fR | \fIprovider\fR }
.RS 4
Added in Shorewall 4\&.4\&.26\&. Enables the optional provider associated with the specified
\fIinterface\fR
or
\fIprovider\fR\&. Where more than one provider share a single network interface, a
\fIprovider\fR
name must be given\&.
.RE
.PP
\fBforget \fR[ \fIfilename\fR ]
.RS 4
Deletes
/var/lib/shorewall6\-lite/\fIfilename\fR
and
/var/lib/shorewall6\-lite/save\&. If no
\fIfilename\fR
is given then the file specified by RESTOREFILE in
\m[blue]\fBshorewall6\&.conf\fR\m[]\&\s-2\u[2]\d\s+2(5) is assumed\&.
.RE
.PP
\fBhelp\fR
.RS 4
Displays a syntax summary\&.
.RE
.PP
\fBhits\fR
.RS 4
Generates several reports from shorewall6\-lite log messages in the current log file\&. If the
\fB\-t\fR
option is included, the reports are restricted to log messages generated today\&.
.RE
.PP
\fBiptrace \fR\fIip6tables match expression\fR
.RS 4
This is a low\-level debugging command that causes iptables TRACE log records to be created\&. See iptables(8) for details\&.
.sp
The
\fIiptables match expression\fR
must be one or more matches that may appear in both the raw table OUTPUT and raw table PREROUTING chains\&.
.sp
The trace records are written to the kernel\*(Aqs log buffer with facility = 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\*(Aqs documentation\&.
.RE
.PP
\fBlist\fR
.RS 4
\fBlist\fR
is a synonym for
\fBshow\fR
\-\- please see below\&.
.RE
.PP
\fBlogdrop \fR\fIaddress\fR
.RS 4
Causes traffic from the listed
\fIaddress\fRes to be logged then discarded\&. Logging occurs at the log level specified by the BLACKLIST_LOGLEVEL setting in
\m[blue]\fBshorewall6\&.conf\fR\m[]\&\s-2\u[2]\d\s+2
(5)\&.
.RE
.PP
\fBlogwatch \fR[\-\fBm\fR] [\fIrefresh\-interval\fR]
.RS 4
Monitors the log file specified by the LOGFILE option in
\m[blue]\fBshorewall6\&.conf\fR\m[]\&\s-2\u[2]\d\s+2(5) and produces an audible alarm when new shorewall6\-lite messages are logged\&.
.sp
The
\fB\-m\fR
option causes the MAC address of each packet source to be displayed if that information is available\&.
.sp
The
\fIrefresh\-interval\fR
specifies the time in seconds between screen refreshes\&. You can enter a negative number by preceding the number with "\-\-" (e\&.g\&.,
\fBshorewall6\-lite logwatch \-\- \-30\fR)\&. In this case, when a packet count changes, you will be prompted to hit any key to resume screen refreshes\&.
.RE
.PP
\fBlogreject \fR\fIaddress\fR
.RS 4
Causes traffic from the listed
\fIaddress\fRes to be logged then rejected\&. Logging occurs at the log level specified by the BLACKLIST_LOGLEVEL setting in
\m[blue]\fBshorewall6\&.conf\fR\m[]\&\s-2\u[2]\d\s+2
(5)\&.
.RE
.PP
\fBls\fR
.RS 4
\fBls\fR
is a synonym for
\fBshow\fR
\-\- please see below\&.
.RE
.PP
\fBnoiptrace \fR\fIip6tables match expression\fR
.RS 4
This is a low\-level debugging command that cancels a trace started by a preceding
\fBiptrace\fR
command\&.
.sp
The
\fIip6tables match expression\fR
must be one given in the
\fBiptrace\fR
command being canceled\&.
.RE
.PP
\fBopen\fR \fIsource\fR \fIdest\fR [ \fIprotocol\fR [ \fIport\fR ] ]
.RS 4
Added in Shorewall 4\&.6\&.8\&. This command requires that the firewall be in the started state and that DYNAMIC_BLACKLIST=Yes in
\m[blue]\fBshorewall6\&.conf (5)\fR\m[]\&\s-2\u[4]\d\s+2\&. The effect of the command is to temporarily open the firewall for connections matching the parameters\&.
.sp
The
\fIsource\fR
and
\fIdest\fR
parameters may each be specified as
\fBall\fR
if you don\*(Aqt wish to restrict the connection source or destination respectively\&. Otherwise, each must contain a host or network address or a valid DNS name\&.
.sp
The
\fIprotocol\fR
may be specified either as a number or as a name listed in /etc/protocols\&. The
\fIport\fR
may be specified numerically or as a name listed in /etc/services\&.
.sp
To reverse the effect of a successful
\fBopen\fR
command, use the
\fBclose\fR
command with the same parameters or simply restart the firewall\&.
.sp
Example: To open the firewall for SSH connections to address 2001:470:b:227::1, the command would be:
.sp
.if n \{\
.RS 4
.\}
.nf
    shorewall6\-lite open all 2001:470:b:227::1 tcp 22
.fi
.if n \{\
.RE
.\}
.sp
To reverse that command, use:
.sp
.if n \{\
.RS 4
.\}
.nf
    shorewall6\-lite close all 2001:470:b:227::1 tcp 22
.fi
.if n \{\
.RE
.\}
.RE
.PP
\fBreenable\fR{ \fIinterface\fR | \fIprovider\fR }
.RS 4
Added in Shorewall 4\&.6\&.9\&. This is equivalent to a
\fBdisable\fR
command followed by an
\fBenable\fR
command on the specified
\fIinterface\fR
or
\fIprovider\fR\&.
.RE
.PP
\fBreject\fR\fI address\fR
