6 firewall-offline-cmd - firewalld offline command line client
7
9 firewall-offline-cmd [OPTIONS...]
10
12 firewall-offline-cmd is an offline command line client of the firewalld
13 daemon. It should be used only if the firewalld service is not running.
14 For example to migrate from system-config-firewall/lokkit or in the
15 install environment to configure firewall settings with kickstart.
16 Some lokkit options can not be automatically converted for firewalld,
18 they will result in an error or warning message. This tool tries to
19 convert as much as possible, but there are limitations for example with
20 custom rules, modules and masquerading.
21 Check the firewall configuration after using this tool.
23
25 If no options are given, configuration from
26 /etc/sysconfig/system-config-firewall will be migrated.
27 Sequence options are the options that can be specified multiple times,
29 the exit code is 0 if there is at least one item that succeeded. The
30 ALREADY_ENABLED (11), NOT_ENABLED (12) and also ZONE_ALREADY_SET (16)
31 errors are treated as succeeded. If there are issues while parsing the
32 items, then these are treated as warnings and will not change the
33 result as long as there is a succeeded one. Without any succeeded item,
34 the exit code will depend on the error codes. If there is exactly one
35 error code, then this is used. If there are more than one then
36 UNKNOWN_ERROR (254) will be used.
37 The following options are supported:
39 General Options
41 -h, --help
42 Prints a short help text and exists.
43 -V, --version
45 Prints the version string of firewalld and exits.
46 -q, --quiet
48 Do not print status messages.
49 --default-config
51 Path to firewalld default configuration. This usually defaults to
52 /usr/lib/firewalld.
53 --system-config
55 Path to firewalld system (user) configuration. This usually
56 defaults to /etc/firewalld.
57 Status Options
59 --enabled
60 Enable the firewall. This option is a default option and will
61 activate the firewall if not already enabled as long as the option
62 --disabled is not given.
63 --disabled
65 Disable the firewall by disabling the firewalld service.
66 --check-config
68 Run checks on the permanent (default and system) configuration.
69 This includes XML validity and semantics.
70 This is may be used with --system-config to check the validity of
72 handwritten configuration files before copying them to the standard
73 location.
74 Lokkit Compatibility Options
76 These options are nearly identical to the options of lokkit.
77 --migrate-system-config-firewall=file
79 Migrate system-config-firewall configuration from the given file.
80 No further
81 --addmodule=module
83 This option will result in a warning message and will be ignored.
84 Handling of netfilter helpers has been merged into services
86 completely. Adding or removing netfilter helpers outside of
87 services is therefore not needed anymore. For more information on
88 handling netfilter helpers in services, please have a look at
89 firewalld.zone(5).
90 --removemodule
92 This option will result in a warning message and will be ignored.
93 Handling of netfilter helpers has been merged into services
95 completely. Adding or removing netfilter helpers outside of
96 services is therefore not needed anymore. For more information on
97 handling netfilter helpers in services, please have a look at
98 firewalld.zone(5).
99 --remove-service=service
101 Remove a service from the default zone. This option can be
102 specified multiple times.
103 The service is one of the firewalld provided services. To get a
105 list of the supported services, use firewall-cmd --get-services.
106 -s service, --service=service
108 Add a service to the default zone. This option can be specified
109 multiple times.
110 The service is one of the firewalld provided services. To get a
112 list of the supported services, use firewall-cmd --get-services.
113 -p portid[-portid]:protocol, --port=portid[-portid]:protocol
115 Add the port to the default zone. This option can be specified
116 multiple times.
117 The port can either be a single port number or a port range
119 portid-portid. The protocol can either be tcp, udp, sctp or dccp.
120 -t interface, --trust=interface
122 This option will result in a warning message.
123 Mark an interface as trusted. This option can be specified multiple
125 times. The interface will be bound to the trusted zone.
126 If the interface is used in a NetworkManager managed connection or
128 if there is an ifcfg file for this interface, the zone will be
129 changed to the zone defined in the configuration as soon as it gets
130 activated. To change the zone of a connection use
131 nm-connection-editor and set the zone to trusted, for an ifcfg
132 file, use an editor and add "ZONE=trusted". If the zone is not
133 defined in the ifcfg file, the firewalld default zone will be used.
134 -m interface, --masq=interface
136 This option will result in a warning message.
137 Masquerading will be enabled in the default zone. The interface
139 argument will be ignored. This is for IPv4 only.
140 --custom-rules=[type:][table:]filename
142 This option will result in a warning message and will be ignored.
143 Custom rule files are not supported by firewalld.
145 --forward-port=if=interface:port=port:proto=protocol[:toport=destination
147 port:][:toaddr=destination address]
148 This option will result in a warning message.
149 Add the IPv4 forward port in the default zone. This option can be
151 specified multiple times.
152 The port can either be a single port number portid or a port range
154 portid-portid. The protocol can either be tcp, udp, sctp or dccp.
155 The destination address is an IP address.
156 --block-icmp=icmptype
158 This option will result in a warning message.
159 Add an ICMP block for icmptype in the default zone. This option can
161 be specified multiple times.
162 The icmptype is the one of the icmp types firewalld supports. To
164 get a listing of supported icmp types: firewall-cmd --get-icmptypes
165 Log Denied Options
167 --get-log-denied
168 Print the log denied setting.
169 --set-log-denied=value

172 FORWARD and OUTPUT chains for the default rules and also final
173 reject and drop rules in zones for the configured link-layer packet
174 type. The possible values are: all, unicast, broadcast, multicast
175 and off. The default setting is off, which disables the logging.
176 This is a runtime and permanent change and will also reload the
178 firewall to be able to add the logging rules.

331 The service is one of the firewalld provided services. To get a
333 list of the supported services, use firewall-cmd --get-services.
334 Note: Some services define connection tracking helpers. Helpers
336 that may operate in client mode (e.g. tftp) must be added to an
337 outbound policy instead of a zone to take effect for clients.
338 Otherwise the helper will not be applied to the outbound traffic.
339 The related traffic, as defined by the connection tracking helper,
340 on the return path (ingress) will be allowed by the stateful
341 firewall rules.
342 An example of an outbound policy for connection tracking helpers:
344 # firewall-cmd --new-policy clientConntrack
346 # firewall-cmd --policy clientConntrack --add-ingress-zone HOST
347 # firewall-cmd --policy clientConntrack --add-egress-zone ANY

569 the pseudo-zones: HOST, ANY.
570 HOST is used for traffic originating from the host machine, i.e.
572 the host running firewalld.
573 ANY is used for traffic originating from any zone. This can be
575 thought of as a wild card for zones. However it does not include
576 traffic originating from the host machine - use HOST for that.

601 Options to Handle Bindings of Interfaces
603 Binding an interface to a zone means that this zone settings are used
604 to restrict traffic via the interface.
605 Options in this section affect only one particular zone. If used with
607 --zone=zone option, they affect the zone zone. If the option is
608 omitted, they affect default zone (see --get-default-zone).
609 For a list of predefined zones use firewall-cmd --get-zones.
611 An interface name is a string up to 16 characters long, that may not
613 contain ' ', '/', '!' and '*'.
614 [--zone=zone] --list-interfaces
616 List interfaces that are bound to zone zone as a space separated
617 list. If zone is omitted, default zone will be used.
618 [--zone=zone] --add-interface=interface
620 Bind interface interface to zone zone. If zone is omitted, default
621 zone will be used.
622 [--zone=zone] --change-interface=interface
624 Change zone the interface interface is bound to to zone zone. If
625 zone is omitted, default zone will be used. If old and new zone are
626 the same, the call will be ignored without an error. If the
627 interface has not been bound to a zone before, it will behave like
628 --add-interface.
629 [--zone=zone] --query-interface=interface
631 Query whether interface interface is bound to zone zone. Returns 0
632 if true, 1 otherwise.
633 [--zone=zone] --remove-interface=interface
635 Remove binding of interface interface from zone zone. If zone is
636 omitted, default zone will be used.
637 Options to Handle Bindings of Sources
639 Binding a source to a zone means that this zone settings will be used
640 to restrict traffic from this source.
641 A source address or address range is either an IP address or a network
643 IP address with a mask for IPv4 or IPv6 or a MAC address or an ipset
644 with the ipset: prefix. For IPv4, the mask can be a network mask or a
645 plain number. For IPv6 the mask is a plain number. The use of host
646 names is not supported.
647 Options in this section affect only one particular zone. If used with
649 --zone=zone option, they affect the zone zone. If the option is
650 omitted, they affect default zone (see --get-default-zone).
651 For a list of predefined zones use firewall-cmd --get-zones.
653 [--zone=zone] --list-sources
655 List sources that are bound to zone zone as a space separated list.
656 If zone is omitted, default zone will be used.
657 [--zone=zone] --add-source=source[/mask]|MAC|ipset:ipset

660 be used.
661 [--zone=zone] --change-source=source[/mask]|MAC|ipset:ipset
663 Change zone the source is bound to to zone zone. If zone is
664 omitted, default zone will be used. If old and new zone are the
665 same, the call will be ignored without an error. If the source has
666 not been bound to a zone before, it will behave like --add-source.
667 [--zone=zone] --query-source=source[/mask]|MAC|ipset:ipset
669 Query whether the source is bound to the zone zone. Returns 0 if

990 Direct Options
992 DEPRECATED
993 The direct interface has been deprecated. It will be removed in a
994 future release. It is superseded by policies, see
995 firewalld.policies(5).
996 The direct options give a more direct access to the firewall. These
998 options require user to know basic iptables concepts, i.e. table
999 (filter/mangle/nat/...), chain (INPUT/OUTPUT/FORWARD/...), commands
1000 (-A/-D/-I/...), parameters (-p/-s/-d/-j/...) and targets
1001 (ACCEPT/DROP/REJECT/...).
1002 Direct options should be used only as a last resort when it's not
1004 possible to use for example --add-service=service or
1005 --add-rich-rule='rule'.
1006 Warning: Direct rules behavior is different depending on the value of
1008 FirewallBackend. See CAVEATS in firewalld.direct(5).
1009 The first argument of each option has to be ipv4 or ipv6 or eb. With
1011 ipv4 it will be for IPv4 (iptables(8)), with ipv6 for IPv6
1012 (ip6tables(8)) and with eb for ethernet bridges (ebtables(8)).
1013 --direct --get-all-chains
1015 Get all chains added to all tables.
1016 This option concerns only chains previously added with --direct
1018 --add-chain.
1019 --direct --get-chains { ipv4 | ipv6 | eb } table
1021 Get all chains added to table table as a space separated list.
1022 This option concerns only chains previously added with --direct
1024 --add-chain.
1025 --direct --add-chain { ipv4 | ipv6 | eb } table chain
1027 Add a new chain with name chain to table table.
1028 There already exist basic chains to use with direct options, for
1030 example INPUT_direct chain (see iptables-save | grep direct output
1031 for all of them). These chains are jumped into before chains for
1032 zones, i.e. every rule put into INPUT_direct will be checked before
1033 rules in zones.
1034 --direct --remove-chain { ipv4 | ipv6 | eb } table chain
1036 Remove the chain with name chain from table table.
1037 --direct --query-chain { ipv4 | ipv6 | eb } table chain
1039 Return whether a chain with name chain exists in table table.
1040 Returns 0 if true, 1 otherwise.
1041 This option concerns only chains previously added with --direct
1043 --add-chain.
1044 --direct --get-all-rules
1046 Get all rules added to all chains in all tables as a newline
1047 separated list of the priority and arguments.
1048 --direct --get-rules { ipv4 | ipv6 | eb } table chain
1050 Get all rules added to chain chain in table table as a newline
1051 separated list of the priority and arguments.
1052 --direct --add-rule { ipv4 | ipv6 | eb } table chain priority args
1054 Add a rule with the arguments args to chain chain in table table
1055 with priority priority.
1056 The priority is used to order rules. Priority 0 means add rule on
1058 top of the chain, with a higher priority the rule will be added
1059 further down. Rules with the same priority are on the same level
1060 and the order of these rules is not fixed and may change. If you
1061 want to make sure that a rule will be added after another one, use
1062 a low priority for the first and a higher for the following.
1063 --direct --remove-rule { ipv4 | ipv6 | eb } table chain priority args
1065 Remove a rule with priority and the arguments args from chain chain
1066 in table table.
1067 --direct --remove-rules { ipv4 | ipv6 | eb } table chain
1069 Remove all rules in the chain with name chain exists in table
1070 table.
1071 This option concerns only rules previously added with --direct
1073 --add-rule in this chain.
1074 --direct --query-rule { ipv4 | ipv6 | eb } table chain priority args
1076 Return whether a rule with priority and the arguments args exists
1077 in chain chain in table table. Returns 0 if true, 1 otherwise.
1078 --direct --get-all-passthroughs
1080 Get all permanent passthrough as a newline separated list of the
1081 ipv value and arguments.
1082 --direct --get-passthroughs { ipv4 | ipv6 | eb }
1084 Get all permanent passthrough rules for the ipv value as a newline
1085 separated list of the priority and arguments.
1086 --direct --add-passthrough { ipv4 | ipv6 | eb } args
1088 Add a permanent passthrough rule with the arguments args for the
1089 ipv value.
1090 --direct --remove-passthrough { ipv4 | ipv6 | eb } args
1092 Remove a permanent passthrough rule with the arguments args for the
1093 ipv value.
1094 --direct --query-passthrough { ipv4 | ipv6 | eb } args
1096 Return whether a permanent passthrough rule with the arguments args
1097 exists for the ipv value. Returns 0 if true, 1 otherwise.
1098 Lockdown Options
1100 Local applications or services are able to change the firewall
1101 configuration if they are running as root (example: libvirt) or are
1102 authenticated using PolicyKit. With this feature administrators can
1103 lock the firewall configuration so that only applications on lockdown
1104 whitelist are able to request firewall changes.
1105 The lockdown access check limits D-Bus methods that are changing
1107 firewall rules. Query, list and get methods are not limited.
1108 The lockdown feature is a very light version of user and application
1110 policies for firewalld and is turned off by default.
1111 --lockdown-on
1113 Enable lockdown. Be careful - if firewall-cmd is not on lockdown
1114 whitelist when you enable lockdown you won't be able to disable it
1115 again with firewall-cmd, you would need to edit firewalld.conf.
1116 --lockdown-off
1118 Disable lockdown.
1119 --query-lockdown
1121 Query whether lockdown is enabled. Returns 0 if lockdown is
1122 enabled, 1 otherwise.
1123 Lockdown Whitelist Options
1125 The lockdown whitelist can contain commands, contexts, users and user
1126 ids.
1127 If a command entry on the whitelist ends with an asterisk '*', then all
1129 command lines starting with the command will match. If the '*' is not
1130 there the absolute command inclusive arguments must match.
1131 Commands for user root and others is not always the same. Example: As
1133 root /bin/firewall-cmd is used, as a normal user /usr/bin/firewall-cmd
1134 is be used on Fedora.
1135 The context is the security (SELinux) context of a running application
1137 or service. To get the context of a running application use ps -e
1138 --context.
1139 Warning: If the context is unconfined, then this will open access for
1141 more than the desired application.
1142 The lockdown whitelist entries are checked in the following order:
1144 1. context
1145 2. uid
1146 3. user
1147 4. command
