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.
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 exists.

-V, --version

Prints the version string of firewalld and exits.

-q, --quiet

Do not print status messages.

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.

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.

Automatic Helpers Options

--get-automatic-helpers

Print the automatic helpers setting.

--set-automatic-helpers=value

For the secure use of iptables and connection tracking helpers it is recommended to turn AutomaticHelpers off. But this might have side effects on other services using the netfilter helpers as the sysctl setting in /proc/sys/net/netfilter/nf_conntrack_helper will be changed. With the system setting, the default value set in the kernel or with sysctl will be used. Possible values are: yes, no and system. The default value is system.

This is a runtime and permanent change and will also reload the firewall to be able to make the helpers usable.

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.

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'.
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 }

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
