firewallctl(1)
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

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

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

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.

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
Returns the minimal mark setting.
Marks up to this minimum are free for use for example in the
direct interface. If more free marks are needed, increase the
minimum in the firewalld.conf file.
EXIT CODES
On success 0 is returned. On failure the output is red colored and exit code is either 2 in case of wrong command-line option usage or one of the following error codes in other cases: String Code ALREADY_ENABLED 11 NOT_ENABLED 12 COMMAND_FAILED 13 NO_IPV6_NAT 14 PANIC_MODE 15 ZONE_ALREADY_SET 16 UNKNOWN_INTERFACE 17 ZONE_CONFLICT 18 BUILTIN_CHAIN 19 EBTABLES_NO_REJECT 20 NOT_OVERLOADABLE 21 NO_DEFAULTS 22 BUILTIN_ZONE 23 BUILTIN_SERVICE 24 BUILTIN_ICMPTYPE 25 NAME_CONFLICT 26 NAME_MISMATCH 27 PARSE_ERROR 28 ACCESS_DENIED 29 UNKNOWN_SOURCE 30 RT_TO_PERM_FAILED 31 IPSET_WITH_TIMEOUT 32 BUILTIN_IPSET 33 ALREADY_SET 34 MISSING_IMPORT 35 DBUS_ERROR 36 BUILTIN_HELPER 37 INVALID_ACTION 100 INVALID_SERVICE 101 INVALID_PORT 102 INVALID_PROTOCOL 103 INVALID_INTERFACE 104 INVALID_ADDR 105 INVALID_FORWARD 106 INVALID_ICMPTYPE 107 INVALID_TABLE 108 INVALID_CHAIN 109 INVALID_TARGET 110 INVALID_IPV 111 INVALID_ZONE 112 INVALID_PROPERTY 113 INVALID_VALUE 114 INVALID_OBJECT 115 INVALID_NAME 116 INVALID_FILENAME 117 INVALID_DIRECTORY 118 INVALID_TYPE 119 INVALID_SETTING 120 INVALID_DESTINATION 121 INVALID_RULE 122 INVALID_LIMIT 123 INVALID_FAMILY 124 INVALID_LOG_LEVEL 125 INVALID_AUDIT_TYPE 126 INVALID_MARK 127 INVALID_CONTEXT 128 INVALID_COMMAND 129 INVALID_USER 130 INVALID_UID 131 INVALID_MODULE 132 INVALID_PASSTHROUGH 133 INVALID_MAC 134 INVALID_IPSET 135 INVALID_ENTRY 136 INVALID_OPTION 137 INVALID_HELPER 138 MISSING_TABLE 200 MISSING_CHAIN 201 MISSING_PORT 202 MISSING_PROTOCOL 203 MISSING_ADDR 204 MISSING_NAME 205 MISSING_SETTING 206 MISSING_FAMILY 207 NOT_RUNNING 252 NOT_AUTHORIZED 253 UNKNOWN_ERROR 254
