NAME
firewall-offline-cmd - firewalld offline command line client
SYNOPSIS
|
firewall-offline-cmd [OPTIONS...] |
DESCRIPTION
firewall-offline-cmd is an offline command line client of the firewalld daemon. It should be used only if the firewalld service is not running. For example to migrate from system-config-firewall/lokkit or in the install environment to configure firewall settings with kickstart.
Some lokkit options can not be automatically converted for firewalld, they will result in an error or warning message. This tool tries to convert as much as possible, but there are limitations for example with custom rules, modules and masquerading.
Check the firewall configuration after using this tool.
OPTIONS
If no options are given, configuration from /etc/sysconfig/system-config-firewall will be migrated.
Sequence options are the options that can be specified multiple times, the exit code is 0 if there is at least one item that succeeded. 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 exists.
-V, --version
Prints the version string of firewalld and exits.
-q, --quiet
Do not print status messages.
--default-config
Path to firewalld default configuration. This usually defaults to /usr/lib/firewalld.
--system-config
Path to firewalld system (user) configuration. This usually defaults to /etc/firewalld.
Status
Options
--enabled
Enable the firewall. This option is a default option and will activate the firewall if not already enabled as long as the option --disabled is not given.
--disabled
Disable the firewall by disabling the firewalld service.
--check-config
Run checks on the permanent (default and system) configuration. This includes XML validity and semantics.
This is may be used with --system-config to check the validity of handwritten configuration files before copying them to the standard location.
Lokkit
Compatibility Options
These options are nearly identical to the options of
lokkit.
--migrate-system-config-firewall=file
Migrate system-config-firewall configuration from the given file. No further
--addmodule=module
This option will result in a warning message and will be ignored.
Handling of netfilter helpers has been merged into services completely. Adding or removing netfilter helpers outside of services is therefore not needed anymore. For more information on handling netfilter helpers in services, please have a look at firewalld.zone(5).
--removemodule
This option will result in a warning message and will be ignored.
Handling of netfilter helpers has been merged into services completely. Adding or removing netfilter helpers outside of services is therefore not needed anymore. For more information on handling netfilter helpers in services, please have a look at firewalld.zone(5).
--remove-service=service
Remove a service from the default zone. This option can be specified multiple times.
The service is one of the firewalld provided services. To get a list of the supported services, use firewall-cmd --get-services.
-s service, --service=service
Add a service to the default zone. This option can be specified multiple times.
The service is one of the firewalld provided services. To get a list of the supported services, use firewall-cmd --get-services.
-p portid[-portid]:protocol, --port=portid[-portid]:protocol
Add the port to the default zone. This option can be specified multiple times.
The port can either be a single port number or a port range portid-portid. The protocol can either be tcp, udp, sctp or dccp.
-t interface, --trust=interface
This option will result in a warning message.
Mark an interface as trusted. This option can be specified multiple times. The interface will be bound to the trusted zone.
If the interface is used in a NetworkManager managed connection or if there is an ifcfg file for this interface, the zone will be changed to the zone defined in the configuration as soon as it gets activated. To change the zone of a connection use nm-connection-editor and set the zone to trusted, for an ifcfg file, use an editor and add "ZONE=trusted". If the zone is not defined in the ifcfg file, the firewalld default zone will be used.
-m interface, --masq=interface
This option will result in a warning message.
Masquerading will be enabled in the default zone. The interface argument will be ignored. This is for IPv4 only.
--custom-rules=[type:][table:]filename
This option will result in a warning message and will be ignored.
Custom rule files are not supported by firewalld.
--forward-port=if=interface:port=port:proto=protocol[:toport=destination port:][:toaddr=destination address]
This option will result in a warning message.
Add the IPv4 forward port in the default zone. This option can be specified multiple times.
The port can either be a single port number portid or a port range portid-portid. The protocol can either be tcp, udp, sctp or dccp. The destination address is an IP address.
--block-icmp=icmptype
This option will result in a warning message.
Add an ICMP block for icmptype in the default zone. This option can be specified multiple times.
The icmptype is the one of the icmp types firewalld supports. To get a listing of supported icmp types: firewall-cmd --get-icmptypes
Log Denied
Options
--get-log-denied
Print the log denied setting.
--set-log-denied=value
Add logging rules 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.
This is a runtime and permanent change and will also reload the firewall to be able to add the logging rules.
Zone Options
--get-default-zone
Print default zone for connections and interfaces.
--set-default-zone=zone
Set 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.

Options to
Adapt and Query Zones and Policies
Options in this section affect only one particular zone or
policy. If used with --zone=zone or
--policy=policy option, they affect the
specified zone or policy. If both options are omitted, they
affect default zone (see --get-default-zone).
[--zone=zone] [--policy=policy] --list-all
List everything added or enabled.
[--zone=zone] [--policy=policy] --get-target
Get the target.
[--zone=zone] [--policy=policy] --set-target=zone
Set the target.
For zones target is one of: default, ACCEPT, DROP, REJECT
For policies target is one of: CONTINUE, ACCEPT, DROP, REJECT
default is similar to REJECT, but has special meaning in the following scenarios:
1. ICMP explicitly allowed
At the end of the zone's ruleset ICMP packets are explicitly allowed.
2. forwarded packets follow the target of the egress zone
In the case of forwarded packets, if the ingress zone uses default then whether or not the packet will be allowed is determined by the egress zone.
For a forwarded packet that ingresses zoneA and egresses zoneB:
• if zoneA's target is ACCEPT, DROP, or REJECT then the packet is accepted, dropped, or rejected respectively.
• if zoneA's target is default, then the packet is accepted, dropped, or rejected based on zoneB's target. If zoneB's target is also default, then the packet will be rejected by firewalld's catchall reject.
3. Zone drifting from source-based zone to interface-based zone
This only applies if AllowZoneDrifting is enabled. See firewalld.conf(5).
If a packet ingresses a source-based zone with a target of default, it may still enter an interface-based zone (including the default zone).

Direct
Options
The direct options give a more direct access to the
firewall. These options require user to know basic iptables
concepts, i.e. table (filter/mangle/nat/...),
chain (INPUT/OUTPUT/FORWARD/...), commands
(-A/-D/-I/...), parameters (-p/-s/-d/-j/...) and
targets (ACCEPT/DROP/REJECT/...).
Direct options should be used only as a last resort when it's not possible to use for example --add-service=service or --add-rich-rule='rule'.
Warning: Direct rules behavior is different depending on the value of FirewallBackend. See CAVEATS in firewalld.direct(5).
The first argument of each option has to be ipv4 or ipv6 or eb. With ipv4 it will be for IPv4 (iptables(8)), with ipv6 for IPv6 (ip6tables(8)) and with eb for ethernet bridges (ebtables(8)).
--direct --get-all-chains
Get all chains added to all tables.
This option concerns only chains previously added with --direct --add-chain.
--direct --get-chains { ipv4 | ipv6 | eb } table
Get all chains added to table table as a space separated list.
This option concerns only chains previously added with --direct --add-chain.
--direct --add-chain { ipv4 | ipv6 | eb } table chain
Add a new chain with name chain to table table.
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 --remove-chain { ipv4 | ipv6 | eb } table chain
Remove the chain with name chain from table table.
--direct --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.
--direct --get-all-rules
Get all rules added to all chains in all tables as a newline separated list of the priority and arguments.
--direct --get-rules { ipv4 | ipv6 | eb } table chain
Get all rules added to chain chain in table table as a newline separated list of the priority and arguments.
--direct --add-rule { ipv4 | ipv6 | eb } table chain priority args
Add 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 --remove-rule { ipv4 | ipv6 | eb } table chain priority args
Remove a rule with priority and the arguments args from chain chain in table table.
--direct --remove-rules { ipv4 | ipv6 | eb } table chain
Remove all rules in the chain with name chain exists in table table.
This option concerns only rules previously added with --direct --add-rule in this chain.
--direct --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.
--direct --get-all-passthroughs
Get all permanent passthrough as a newline separated list of the ipv value and arguments.
--direct --get-passthroughs { ipv4 | ipv6 | eb }
Get all permanent passthrough rules for the ipv value as a newline separated list of the priority and arguments.
--direct --add-passthrough { ipv4 | ipv6 | eb } args
Add a permanent passthrough rule with the arguments args for the ipv value.
--direct --remove-passthrough { ipv4 | ipv6 | eb } args
Remove a permanent passthrough rule with the arguments args for the ipv value.
--direct --query-passthrough { ipv4 | ipv6 | eb } args
Return whether a permanent passthrough rule with the arguments args exists for the ipv value. Returns 0 if true, 1 otherwise.
Lockdown
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-on
Enable 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.
--lockdown-off
Disable lockdown.
--query-lockdown
Query whether lockdown is enabled. Returns 0 if lockdown is enabled, 1 otherwise.
Lockdown
Whitelist Options
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
--list-lockdown-whitelist-commands
List all command lines that are on the whitelist.
--add-lockdown-whitelist-command=command
Add the command to the whitelist.
--remove-lockdown-whitelist-command=command
Remove the command from the whitelist.
--query-lockdown-whitelist-command=command
Query whether the command is on the whitelist. Returns 0 if true, 1 otherwise.
--list-lockdown-whitelist-contexts
List all contexts that are on the whitelist.
--add-lockdown-whitelist-context=context
Add the context context to the whitelist.
--remove-lockdown-whitelist-context=context
Remove the context from the whitelist.
--query-lockdown-whitelist-context=context
Query whether the context is on the whitelist. Returns 0 if true, 1 otherwise.
--list-lockdown-whitelist-uids
List all user ids that are on the whitelist.
--add-lockdown-whitelist-uid=uid
Add the user id uid to the whitelist.
--remove-lockdown-whitelist-uid=uid
Remove the user id uid from the whitelist.
--query-lockdown-whitelist-uid=uid
Query whether the user id uid is on the whitelist. Returns 0 if true, 1 otherwise.
--list-lockdown-whitelist-users
List all user names that are on the whitelist.
--add-lockdown-whitelist-user=user
Add the user name user to the whitelist.
--remove-lockdown-whitelist-user=user
Remove the user name user from the whitelist.
--query-lockdown-whitelist-user=user
Query whether the user name user is on the whitelist. Returns 0 if true, 1 otherwise.
Policy
Options
--policy-server
Change Polkit actions to 'server' (more restricted)
--policy-desktop
Change Polkit actions to 'desktop' (less restricted)
