Ubuntu Manpage: firewallctl - firewalld command line client

NAME

       firewallctl - firewalld command line client

SYNOPSIS

       firewallctl [OPTIONS...]

DESCRIPTION

       firewallctl is an alternate command line client of the firewalld daemon. It provides
       interface to manage runtime and permanent configuration.

       The runtime configuration in firewalld is separated from the permanent configuration. This
       means that things can get changed in the runtime or permanent configuration.

OPTIONS

For sequence options, this are the options that can be specified multiple times, the exit
code is 0 if there is at least one item that succeded. The ALREADY_ENABLED (11),
NOT_ENABLED (12) and also ZONE_ALREADY_SET (16) errors are treated as succeeded. If there
are issues while parsing the items, then these are treated as warnings and will not change
the result as long as there is a succeeded one. Without any succeeded item, the exit code
will depend on the error codes. If there is exactly one error code, then this is used. If
there are more than one then UNKNOWN_ERROR (254) will be used.

The following options are supported:

General Options
-h, --help
Prints a short help text and exits.

-v, --verbose
Be more verbose while printing.

-q, --quiet
Do not print status messages.

Version Option
version
Print the version string of firewalld. This option is not combinable with other
options.

State Option
state
Check whether the firewalld daemon is active (i.e. running). Returns an exit code 0 if
it is active, NOT_RUNNING otherwise (see the section called “EXIT CODES”). This will
also print the state to STDOUT.

Reload Options
reload [ -c | --complete ]
Reload firewall rules and keep state information. Current permanent configuration will
become new runtime configuration, i.e. all runtime only changes done until reload are
lost with reload if they have not been also in permanent configuration.

With the -c | --complete option, reload firewall completely, even netfilter kernel
modules. This will most likely terminate active connections, because state information
is lost. This option should only be used in case of severe firewall problems. For
example if there are state information problems that no connection can be established
with correct firewall rules.

Runtime To Permanent Option
runtime-to-permanent
Save active runtime configuration and overwrite permanent configuration with it.

The way this is supposed to work is that when configuring firewalld you do runtime
changes only and once you're happy with the configuration and you tested that it works
the way you want, you save the configuration to disk.

List Options
list zones [ -a | --active | -p | --permanent ]
Print predefined zones as a space separated list.

With the -a | --active option, only zones are listed, that are active. That means that
the zones have interface or source bindings.

Print predefined services as a space separated list.

With the -p | --permanent option, services in the permanent environment are listed.

list ipsets [ -p | --permanent ]

Zone Elements
A zone element can be one of:

interface interface
An interface name is a string up to 16 characters long, that may not contain ' ', '/',
'!' and '*'.

If the interface is under control of NetworkManager, it is at first connected to
change the zone for the connection that is using the interface for new or changed
interface bindings. If the setting in NetworkManager fails, the zone binding is
created or changed in firewalld and the limitations below apply.

As a end user you don't need to create or change zone bindings of interfaces in most
cases, because NetworkManager (or legacy network service) adds interfaces into zones
automatically (according to ZONE= option from ifcfg-interface file) if
NM_CONTROLLED=no is not set. You should do it only if there's no
/etc/sysconfig/network-scripts/ifcfg-interface file. If there is such file and you add
interface to zone with this --add-interface option, make sure the zone is the same in
both cases, otherwise the behaviour would be undefined. Please also have a look at the
firewalld(1) man page in the Concepts section. For permanent association of interface
with a zone, see also 'How to set or change a zone for a connection?' in
firewalld.zones(5).

For the addion or change of interfaces that are not under control of NetworkManager:
firewalld tries to change the ZONE setting in the ifcfg file, if an ifcfg file exists
that is using the interface.

Only for the removal of interfaces that are not under control of NetworkManager:
firewalld is not trying to change the ZONE setting in the ifcfg file. This is needed
to make sure that an ifdown of the interface will not result in a reset of the zone
setting to the default zone. Only the zone binding is then removed in firewalld then.

source { address[/mask] | MAC | ipset:ipset }
A source address or address range is either an IP address or a network IP address with
a mask for IPv4 or IPv6 or a MAC address or also an ipset. For IPv4, the mask can be a
network mask or a plain number. For IPv6 the mask is a plain number. The use of host
names is not supported.

service service
A service is a firewalld provided or user created service. To get a list of the
supported services, use firewallctl list services [ -p | --permanent ].

port portid[-portid]/protocol

masquerade
IPv4 masquerading.

Masquerading is useful if the machine is a router and machines connected over an
interface in another zone should be able to use the first connection.

forward-port
port=portid[-portid]:proto=protocol[:toport=portid[-portid]][:toaddr=address[/mask]]
An IPv4 forward port.

The port can either be a single port number portid or a port range portid-portid. The

There already exist basic chains to use with direct options, for example INPUT_direct
chain (see iptables-save | grep direct output for all of them). These chains are
jumped into before chains for zones, i.e. every rule put into INPUT_direct will be
checked before rules in zones.

direct [ -p | --permanent ] query chain { ipv4 | ipv6 | eb } table chain
Return whether a chain with name chain exists in table table. Returns 0 if true, 1
otherwise. This option concerns only chains previously added with direct add chain.

Get all chains added to table table as a space separated list. This option concerns
only chains previously added with direct add chain.

direct [ -p | --permanent ] get all-chains

with direct add chain.

direct [ -p | --permanent ] { add | remove } rule { ipv4 | ipv6 | eb } table chain
priority args
Add or remove a rule with the arguments args to chain chain in table table with
priority priority.

The priority is used to order rules. Priority 0 means add rule on top of the chain,
with a higher priority the rule will be added further down. Rules with the same
priority are on the same level and the order of these rules is not fixed and may
change. If you want to make sure that a rule will be added after another one, use a
low priority for the first and a higher for the following.

direct [ -p | --permanent ] query rule { ipv4 | ipv6 | eb } table chain priority args
Return whether a rule with priority and the arguments args exists in chain chain in
table table. Returns 0 if true, 1 otherwise. This option concerns only rules
previously added with direct add rule.

Get all rules added to chain chain in table table as a newline separated list of the
priority and arguments. This option concerns only rules previously added with direct
add rule.

direct [ -p | --permanent ] { add | remove } passthrough { ipv4 | ipv6 | eb } args
Add a passthrough rule with the arguments args for the ipv value.

direct [ -p | --permanent ] query passthrough { ipv4 | ipv6 | eb } args
Return whether a passthrough rule with the arguments args exists for the ipv value.
Returns 0 if true, 1 otherwise.

direct [ -p | --permanent ] get all-passthroughs
Get all passthrough rules as a newline separated list of the ipv value and arguments.

direct [ -p | --permanent ] get passthroughs { ipv4 | ipv6 | eb }
Get passthrough rules for the ipv value as a newline separated list of the priority
and arguments.

direct passthrough { ipv4 | ipv6 | eb } args
Pass a command through to the firewall. args can be all iptables, ip6tables and
ebtables command line arguments. This command is untracked, which means that firewalld
is not able to provide information about this command later on, also not a listing of
the untracked passthoughs.

Lockdown Whitelist Options
Local applications or services are able to change the firewall configuration if they are
running as root (example: libvirt) or are authenticated using PolicyKit. With this feature
administrators can lock the firewall configuration so that only applications on lockdown
whitelist are able to request firewall changes.

The lockdown access check limits D-Bus methods that are changing firewall rules. Query,
list and get methods are not limited.

The lockdown feature is a very light version of user and application policies for
firewalld and is turned off by default.

lockdown-whitelist [ -p | --permanent ] { add | remove } element..
Add an element or several elements of the same type to the lockdown whitelist.

For possible lockdown whitelist elements see further down.

With the -p or --permanent option, elements are added in the permanent environment.

lockdown-whitelist [ -p | --permanent ] query element..
Return whether the element or several elements of the same type are enabled in the
lockdown whitelist.

For possible lockdown whitelist elements see further down.

With the -p or --permanent option, elements are added in the permanent environment.

lockdown-whitelist [ -p | --permanent ] list { commands | contexts | uids | users }
Return list of elements added for the lockdown whitelist.

With the -p or --permanent option, elements are added in the permanent environment.

Lockdown Whitelist Elements
The lockdown whitelist can contain commands, contexts, users and user ids.

If a command entry on the whitelist ends with an asterisk '*', then all command lines
starting with the command will match. If the '*' is not there the absolute command
inclusive arguments must match.

Commands for user root and others is not always the same. Example: As root
/bin/firewall-cmd is used, as a normal user /usr/bin/firewall-cmd is be used on Fedora.

The context is the security (SELinux) context of a running application or service. To get
the context of a running application use ps -e --context.

Warning: If the context is unconfined, then this will open access for more than the
desired application.

The lockdown whitelist entries are checked in the following order:
1. context
2. uid
3. user
4. command

A lockdown whitelist element can be one of:

command 'string'
The command string is a complete command line including path and also attributes.

If a command entry ends with an asterisk '*', then all command lines starting with the
command will match. If the '*' is not there the absolute command inclusive arguments
must match.

Commands for user root and others is not always the same, the used path depends on the
use of the PATH environment variable.

context string
The context is the security (SELinux) context of a running application or service.

To get the context of a running application use ps -e --context and search for the
application that should be white-listed.

Warning: If the context of an application is unconfined, then this will open access
for more than the desired application.

user string
The user with the name string will be white-listed.

uid integer
The user with the id userid will be white-listed.

Config Options
config set { default-zone zone | lockdown { on | off } | log-denied value | panic { on |
off } }
Set a firewalld config option.

The possible config options are:

default-zone zone
Set the default zone for connections and interfaces where no zone has been
selected. Setting the default zone changes the zone for the connections or
interfaces, that are using the default zone.

lockdown
Enable or disable lockdown. Be careful - if firewall-cmd is not on lockdown
whitelist when you enable lockdown you won't be able to disable it again with
firewall-cmd, you would need to edit firewalld.conf.

log-denied
If enabled, logging rules are added right before reject and drop rules in the
INPUT, FORWARD and OUTPUT chains for the default rules and also final reject and
drop rules in zones for the configured link-layer packet type. The possible values
are: all, unicast, broadcast, multicast and off. The default setting is off, which
disables the logging.

panic
Enable or disable the panic mode. If enabled, all incoming and outgoing packets
are dropped, active connections will expire. Enable this only if there are serious
problems with your network environment. For example if the machine is getting
hacked in.

After disabling panic mode established connections might work again, if panic mode
was enabled for a short period of time.

config list
List firewalld config options like default-zone, lockdown, log-denied and panic flag.

config get { default-zone | lockdown | log-denied | panic }
Get a firewalld config option.

The possible config options are:

default-zone
Returns the default zone for connections and interfaces.

lockdown
Returns whether lockdown is enabled.

log-denied
Returns the log denied configuration.

panic
Returns 0 if panic mode is enabled, 1 otherwise.

Settings Options
settings list
List firewalld settings like BRIDGE, CleanupOnExit, IPSet, IPSetTypes, IPv4, IPv6,
IPv6_rpfilter, IndividualCalls and MinimalMark.

settings get { BRIDGE | CleanupOnExit | IPSet | IPSetTypes | IPv4 | IPv6 | IPv6_rpfilter |
IndividualCalls | MinimalMark }
Get a firewalld setting.

The supported settings are:

BRIDGE
Returns whether bridge support is available.

CleanupOnExit
Returns whether CleanupOnExit is enabled.

IPSet
Returns whether ipset support is available.

IPSetTypes
Returns the currently supported ipset types. This setting lists all ipset types
that are supported to be used within firewalld. This means the ipset types need to
be supported by kernel and the ipset command and firewalld at the same time.

IPv4
Returns whether ipv4 support is available.

IPv6
Returns whether IPv6 support is available.

IPv6_rpfilter
Returns whether IPv6 rpfilter is enabled.

The IPv6 rpfiler performs a reverse path filter test on a packet for IPv6. If a
reply to the packet would be sent via the same interface that the packet arrived
on, the packet will match and be accepted, otherwise dropped. The rp_filter for
IPv4 is controlled using sysctl.

IndividualCalls
Returns the individual calls setting.

If disabled, combined -restore calls are not used, but individual calls. This
increases the time that is needed to apply changes and to start the daemon, but is
good for debugging.

MinimalMark
