FIREWALL-OFFLINE-C(1)

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 it implicitly allows ICMP packets.

[--zone=zone] [--policy=policy] --set-description=description
    Set description.

[--zone=zone] [--policy=policy] --get-description
    Print description.

[--zone=zone] [--policy=policy] --set-short=description
    Set short description.

[--zone=zone] [--policy=policy] --get-short
    Print short description.

[--zone=zone] [--policy=policy] --list-services
    List services added as a space separated list.

[--zone=zone] [--policy=policy] --add-service=service
    Add a service. 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.

    Note: Some services define connection tracking helpers. Helpers that may operate in client mode (e.g. tftp) must be added to an outbound policy instead of a zone to take effect for clients. Otherwise the helper will not be applied to the outbound traffic. The related traffic, as defined by the connection tracking helper, on the return path (ingress) will be allowed by the stateful firewall rules.

    An example of an outbound policy for connection tracking helpers:

        # firewall-cmd --new-policy clientConntrack
        # firewall-cmd --policy clientConntrack --add-ingress-zone HOST
        # firewall-cmd --policy clientConntrack --add-egress-zone ANY

    HOST is used for traffic originating from the host machine, i.e. the host running firewalld.

    ANY is used for traffic originating from any zone. This can be thought of as a wild card for zones. However it does not include traffic originating from the host machine - use HOST for that.

--policy=policy --remove-ingress-zone=zone
    Remove an ingress zone. This option can be specified multiple times.

  Options to Handle Bindings of Interfaces

Binding an interface to a zone means that this zone settings are used to restrict traffic via the interface.

Options in this section affect only one particular zone. If used with --zone=zone option, they affect the zone zone. If the option is omitted, they affect default zone (see --get-default-zone).

    Change zone the interface interface is bound to to zone zone. If zone is omitted, default zone will be used. If old and new zone are the same, the call will be ignored without an error. If the interface has not been bound to a zone before, it will behave like --add-interface.

[--zone=zone] --query-interface=interface
    Query whether interface interface is bound to zone zone. Returns 0 if true, 1 otherwise.

[--zone=zone] --remove-interface=interface
    Remove binding of interface interface from zone zone. If zone is omitted, default zone will be used.

  Options to Handle Bindings of Sources

Binding a source to a zone means that this zone settings will be used to restrict traffic from this source.

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 an ipset with the ipset: prefix. 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.

Options in this section affect only one particular zone. If used with --zone=zone option, they affect the zone zone. If the option is omitted, they affect default zone (see --get-default-zone).

For a list of predefined zones use firewall-cmd --get-zones.

[--zone=zone] --list-sources
    List sources that are bound to zone zone as a space separated list. If zone is omitted, default zone will be used.

[--zone=zone] --add-source=source[/mask]|MAC|ipset:ipset

  Direct Options

DEPRECATED

    The direct interface has been deprecated. It will be removed in a future release. It is superseded by policies, see firewalld.policies(5).

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)
