NAME
wicked-config.xml - wicked configuration file
SYNOPSIS
/etc/wicked/common.xml
/etc/wicked/server.xml
/etc/wicked/client.xml
/etc/wicked/nanny.xml
DESCRIPTION
These files contain the global configuration options for the wicked
network management service. All files follow the same XML schema.
common.xml contains common definitions that should be used by all
applications. It is sourced by the other configuration files. It can
be used to enable debugging across all wicked components, for instance.
Different components of wicked will load different files on startup;
for instance, the wickedd server process will try to load server.xml.
If that file does not exist, it will fall back to common.xml and try to
read that directly.
The following table shows which wicked commands use which configuration
file:
+--------------+------------+
|Application | Filename |
+--------------+------------+
|wicked | client.xml |
|wickedd | server.xml |
|wickedd-nanny | nanny.xml |
|wickedd-auto4 | auto4.xml |
|wickedd-dhcp4 | dhcp4.xml |
|wickedd-dhcp6 | dhcp6.xml |
+--------------+------------+
GENERAL OPTIONS
The configuration file is an XML document; its root node must be called
<config>.
include
This element can be used to refer to an additional XML configu-
ration file. When parsing a configuration file, wicked will tra-
verse the XML hierarchy once, in the order in which elements
occur in the file. The file referenced by an <include> element
is loaded and parsed at the time the <include> element is
encountered.
Note that the contents of the file will not be "included" in the
way you would expect this from e.g. a macro preprocessor.
Instead, the referenced file must be a proper XML document, and
its top node must also be a config element.
Common pathnames
piddir This element specifies the directory used to write pid files.
The path attribute of this element contains the path to this
directory. The optional mode attribute can be used to specify
the permissions of this directory.
The default is to use /run/wicked, mode 0755.
<statedir path="/run/wicked" mode="0755" />
statedir
This element specifies the location of the directory containing
various files relating to the state of the server. For instance,
temporary files are stored here when starting external programs
like pppd(8).
The path attribute of this element contains the path to this
directory. The optional mode attribute can be used to specify
the permissions of this directory.
The default is to use /run/wicked, mode 0755.
<statedir path="/run/wicked" mode="0755" />
storedir
This element specifies the location of the directory containing
various (reboot) persistent data. For instance, the DHCP DUID
and lease files are is stored in this directory.
The path attribute of this element contains the path to this
directory. The optional mode attribute can be used to specify
the permissions of this directory.
The default is to use /var/lib/wicked, mode 0755.
<statedir path="/var/lib/wicked" mode="0755" />
Miscellaneous
debug This element specifies the default debug facilities to be
enabled. Allowed is a comma separated list of supported facil-
ity names, including set names such as all and most and names
with a "-" prepended for negated facilities, e.g. "all,-xpath".
The 'wicked --debug help' command shows valid facility names.
If a debug level is specified on the command line or via the
WICKED_DEBUG environment variable, the setting from the XML con-
figuration file will be ignored.
DBus service parameters
All configuration options related to the DBus service are grouped below
the <dbus> element. Currently, the following child elements are recog-
nized:
service
This element specifies the DBus service name used, and must be a
valid DBus API name. The default is "org.opensuse.Network".
schema This element specifies the location of the schema files. The
schema defines the various DBus APIs offered by the server, and
how portions of an interface XML description map to their argu-
ments. The schema files do not contain user-serviceable parts,
so it's best to leave this option untouched.
Here's what the default configuration looks like:
<dbus>
<service name="org.opensuse.Network" />
<schema name="/usr/share/wicked/schema/wicked.xml" />
</dbus>
CLIENT ONLY OPTIONS
sources
This specifies a list of sources that the wicked client will
pick up interface configurations from, and their load order.
Child elements of <sources> must be called ifconfig, and are
expected to specify a location attribute.
The location attribute takes the form type:string, where string
may be empty.
+---------+-----------------------------------------------------+
|Type | Description |
+---------+-----------------------------------------------------+
|firmware | Get configuration from firmware, usually iBFT |
|compat | Load interface description using legacy ifcfg files |
|wicked | Load interface description using native wicked XML |
+---------+-----------------------------------------------------+
The firmware type takes no additional string parameter. When
specifying either wicked, you can optionally specify a directory
where to look for XML interface configurations. If no directory
is given, the path defaults to /etc/wicked/ifconfig. When spec-
ifying either compat, you can optionally specify the ifcfg fla-
vor, which can be either suse or redhat. If no flavor is speci-
fied, the result is implementation dependent - but usually, it
will pick the platform default it was compiled on.
The default configuration is this:
<sources>
<ifconfig location="firmware:" />
<ifconfig location="compat:" />
<ifconfig location="wicked:" />
</sources>
ADDRESS CONFIGURATION OPTIONS
The <addrconf> element is evaluated by server applications only, and
controls the behavior of dynamic address configuration protocols such
as DHCP. This options to blacklist e.g. certain DHCP servers, and which
information provided by address configuration to apply.
default-allow-update
Most dynamic address configuration protocols, including DHCP, do
not just provide a list of addresses and routes to install for
the managed network interface, but can be used to provide infor-
mation such as a list of DNS servers, directory information (for
e.g. NIS), etc. A system receiving that information is free to
reconfigure some of its services based on this information. For
instance, it makes a lot of sense to configure the resolver
library to use the DNS servers specified by a DHCP server. On
the other hand, you may want to ignore any NIS information
received via DHCP.
The <default-allow-update> is applied to static and intrinsic
leases, which do not have an own, type and address family spe-
cific <allow-update> element as available under the <dhcp6>,
<dhcp4>, <auto6> and <auto4> sub-elements, which support a sub-
set of the possible facilities listed here. The <default-allow-
update> and the type specific <allow-update> elements enable you
to control which system services wicked will (request and) con-
sider to update in the system.
It contains a list of either empty XML elements e.g.
(<dns/><ntp/>) naming system the facilities or alternatively, a
space separated string list (dns ntp) with the facility names.
The special elements default, none and all enable and disable
the default, none and all updates, respectively. A no- or a - in
the front of a facility name permits to remove/disable a facil-
ity from the currently applied set and enable further supported
facilities, e.g. default,-nis,slp is applying a modified default
set with disabled nis and the optional slp facility enabled
additionally.
The following updater facilities are currently defined:
+--------------+-------------------------------------------------------+
|Name | Description |
+--------------+-------------------------------------------------------+
|default-route | system default route (IPv4 or IPv6) |
|hostname | system hostname |
|dns | update resolv.conf or dns server (via netconfig) |
|nis | NIS client (via netconfig) |
|ntp | NTP servers (via netconfig) |
|smb | SMB settings (no netconfig module implemented) |
|nds | NDS servers (no netconfig module implemented) |
|slp | SLP client (no netconfig module implemented) |
|sip | SIP client (no netconfig module implemented) |
|log | syslog servers (no netconfig module implemented) |
|lpr | print servers (no netconfig module implemented) |
|tz | posix time zone (no netconfig module implemented) |
|mtu | adjust interface mtu (dhcp4) |
|boot | root-path (dhcp4)/boot-url (dhcp6) used in the initrd |
+--------------+-------------------------------------------------------+
Note that administrators wishing to support currently unimple-
mented updaters can do so by configuring external updaters using
the <system-updater> extensions described below.
dhcp4 This element can be used to control the behavior of the DHCP4
supplicant. See below for a list of options.
dhcp6 This element can be used to control the behavior of the DHCP6
supplicant. See below for a list of options.
auto6 This element can be used to control the behavior of AUTO6 pro-
cessing.
DHCP4 SUPPLICANT OPTIONS
The DHCP4 client can be configured through the options listed below.
All of them must be nested in the config node like this:
<addrconf>
<dhcp4>
...
</dhcp4>
</addrconf>
or inside a device name context like:
<addrconf>
<dhcp4>
<device name="eth0" >
...
</device>
</dhcp4>
</addrconf>
create-cid
Specifies the standard client-id type to use:
+--------+--------+-------------------------------------------------------+
|Type | Alias | Description |
+--------+--------+-------------------------------------------------------+
|rfc4361 | dhcp6 | use 0xff as type, followed by DHCPv6 IAID and DUID |
|rfc2132 | hwaddr | use hardware/link layer type, followed by the address |
|disable | none | disables creation (custom client-id is send if given) |
+--------+--------+-------------------------------------------------------+
When the interface configuration does not provide an explicit client-id
(DHCLIENT_CLIENT_ID in ifcfg files or <client-id> xml config/policy
node), wicked will generate a DHCPv4 client-id as specified in this
option.
When set to rfc4361, wicked will create a DHCPv4 client-id using the
DHCPv6 IAID and DUID (see <dhcp6><default-duid> option). This new
rfc4361 client-id is required to perform DDNS updates for ipv4 (A) and
ipv6 (AAAA) address records in the same DNS zone (domain) and mandatory
to use on infiniband interfaces.
When set to rfc2132, wicked will create a DHCPv4 client-id using the
network interface hardware-type and address. This may be needed to
maintain compatibility to e.g. DHCPv4 servers with static leases
explicitly bound to a rfc2132 client-id or having trouble to provide a
lease to a dhcp4 client using the new and longer rfc4361 client-id.
When set to disable, no client-id is created and send by default
(except when the interface config request to acquire a lease contains a
custom/explicit one).
When unspecified, the default behavior depends on the --enable-
dhcp4-rfc4361-cid (default) and --disable-dhcp4-rfc4361-cid configure
options, allowing to revert to use the old rfc2132 client-id at compile
time, i.e. to prereserve behavior like in older releases, but permit to
change to enable the new rfc4361 client-id default at runtime.
Note, that a change of the client-id usually causes to disassociate the
lease and/or DNS records, because it is used in the DHCID DNS record
(see rfc4701).
vendor-class
Specifies the string to be used as the vendor-class option in
the DHCP request. By default, no vendor-class option is sent.
lease-time
Specifies the lease time to request in the DHCP request, in sec-
onds. This also caps the lease time that can be requested in an
interface configuration; any lease-time specified there will be
silently limited to what was specified in the global configura-
tion file. The following will set the default lease time to one
hour:
<lease-time>3600</lease-time>
ignore-server
Using the ip attribute of this element, you can specify the IP
or HW address (currently ethernet devices only) of a faulty DHCP
server that should be ignored:
<ignore-server ip="192.168.8.1" /> <ignore-server
mac="52:54:00:02:c2:67" />
prefer-server
Specify a preferred DHCP server, together with a numeric value
indicating its preference. Again, the address of the server is
specified using the ip or mac attribute.
The numeric preference value is given by the weight, and should
range from -1 to 100. Higher numbers indicate a higher prefer-
ence. A negative value will cause the server to be ignored. If
a response from a server with a weight of 100 is received, it
will be selected immediately. Otherwise, the supplicant will
wait for about one second, and select the server with the high-
est preference afterwards.
The special keywords never and always correspond to -1 and 100,
respectively. If no weight attribute is given, it defaults to
always (100).
The following example will ignore 192.168.8.1, always use the
information from 192.168.8.10 if available, and fall back to
192.168.8.7 if not:
<prefer-server ip="192.168.8.1" weight="never" />
<prefer-server mac="02:03:04:05:06:07" weight="always" />
<prefer-server ip="192.168.8.7" weight="50" />
allow-update
Specify the list of system services that wicked will configure
based on the DHCP lease received. For the syntax of this ele-
ment, please refer to the description of default-allow-update
above. dhcp4 supports all update facilities.
route-options
Specify a space separated list of routing options to request
from dhcp4 server.
+--------------+-------+----------------------------------------------------------+
|Name | | Alias |
+--------------+-------+----------------------------------------------------------+
|classless | csr | RFC 3442 classless static route option 121 |
|ms-classless | mscsr | MS classless static route option code 249 (pre RFC 3442) |
|static-routes | class | Obsolete option 33 requesting static class routes |
+--------------+-------+----------------------------------------------------------+
The RFC 3442 classless static route option provides all routes
with a netmask, includes the default routers and has priority
over other routing options. By default, wicked requests class-
less (121) as well as class static routes (33) and the default
routers option (3) (when enabled in allow-update) to be compati-
ble to old servers or servers not configured to provide class-
less, but only a default router option.
define Permits to define list of custom dhcp options not covered by
wicked yet. The dhcp4 option codes are 8-bit (1..254) bytes.
For non-standard options, it is recommended is to use the DHCPv4
private option code range 224 to 254, see RFC3942 (section 4),
RFC 2939 and www.iana.org/assignments/bootp-dhcp-parameters to
avoid conflicts with options that are or may be defined and
implemented later.
To request support for a specific standard option, issue a fea-
ture request at https://fate.suse.com/ or https://features.open-
suse.org/ (hermes). See CUSTOM DHCP OPTIONS section for more
details.
DHCP6 SUPPLICANT OPTIONS
The DHCP6 client can be configured through the options listed below.
All of them must be nested in the config node like this:
<addrconf>
<dhcp6>
...
</dhcp6>
</addrconf>
or inside a device name context like:
<addrconf>
<dhcp6>
<device name="eth0" >
...
</device>
</dhcp6>
</addrconf>
default-duid
DHCPv6 uses a so-called DUID to identify a DHCP client and an
IAID, that refers to an interface.
DHCPv4 now also defaults to construct its client-id using the
DHCPv6 IAID and DUID as well (see <dhcp4><create-cid> option).
By default, wickedd-dhcp6 will try to generate a DUID based on
the link layer address (MAC) of the device and time (DUID-LLT).
The default-duid element permits to override this behavior and
either specify an explicit DUID as a string of colon separated
hex octets, e.g.:
<default-duid>00:03:00:01:02:00:00:00:00:02</default-duid>
or an advise which duid type to construct or import expressed in
a child element:
<default-duid><duid type element/></default-duid>
using one of the following duid type elements:
llt, DUID type 1, Link-layer address plus time:
Permits to specify the link/hardware type and address in
its hardware and address elements, e.g.:
<llt>
<hardware>ethernet</hardware><address>02:00:00:00:00:02</address>
</llt>
Without arguments, wicked will create the duid-llt using
the hardware type and address of the actual device that
requests a duid first. The time inside of the DUID is
set automatically to the duid creation time.
en, DUID type 2, Vendor Based on IANA Enterprise Number:
Permits to specify a vendor type DUID-EN based on the
IANA assigned enterprise number and an machine identifier
specified in the enterprise-number and identifier ele-
ments, e.g. using IANA number 7057 assigned to SUSE:
<en>
<enterprise-number>7057</enterprise-number>
<identifier>02:00:00:00:00:02</identifier>
</en>
ll, DUID type 3, Link-layer address (without time):
Usage is as for type 1 duid llt, the duid does not con-
tain a time.
uuid, DUID type 4, UUID-Based Unique Identifier:
Permits to specify the effective UUID to use, e.g.:
<uuid>80d732e7-b8dc-45ef-bdae-f9f5e6925cef</uuid>
or import it from /etc/machine-id file:
<uuid><machine-id/></uuid>
or using an explicit path to the machine-id file:
<uuid><machine-id>/etc/machine-id</machine-id></uuid>
or the DMI product id (problematic, may be not available
or not unique):
<uuid><dmi-product-id/></uuid>
Without arguments, wicked will try to import the machine-
id with a fallback to the DMI product id when no machine-
id file exists.
Additionally, the default-duid element supports a per-device
attribute. When enabled via <default-duid per-device="true"/>,
wicked changes to a non-standard behavior and maintains a sepa-
rate duid for each device instead of the same ("default") DUID
for all interfaces and a per device/interface IAID.
This permits to workaround some special cases, where the hosts
should appear to the server using multiple identities, that is
to behave as multiple machines instead as one with multiple
interfaces.
The wickedd daemons store the generated DUIDs in
/run/wicked/duid.xml file. The wicked duid utility command per-
mits to review and modify the duid as needed.
Note: When you change the DUID, make sure to restart the wickedd
service.
lease-time
Specifies the lease time to request in the DHCP request, in sec-
onds. This also caps the lease time that can be requested in an
interface configuration; any lease-time specified there will be
silently limited to what was specified in the global configura-
tion file. The following will set the default lease time to one
hour:
<lease-time>3600</lease-time>
release-retransmits
Specifies the number of lease release retransmissions in the
range 1..5. Default is to send up to 5 (REL_MAX_RC) retransmis-
sions.
info-refresh-time
Specifies a different default for the RFC4242 info refresh time
used when the dhcp6 server does not provide any and permits also
to adjust the acceptable time range in the min and max
attributes, e.g.:
<info-refresh-time min= 600" max="604800">86400</info-refresh-
time>
prefer-server
Specify a preferred DHCP server, together with a numeric value
indicating its preference. The server is identified using its
DUID, which has to be specified via the id attribute.
The numeric preference value is given by the weight, and should
range from -1 to 255. Higher numbers indicate a higher prefer-
ence. A negative value will cause the server to be ignored. If
a response from a server with a weight of 255 is received, it
will be selected immediately. Otherwise, the supplicant will
wait for about one second, and select the server providing an
offer with the best request match and the highest preference
afterwards.
The special keywords never and always correspond to -1 and 255,
respectively. If no weight attribute is given, it defaults to
always (255).
The following example will ignore DHCP offers from the first
server, always use the information from the second (if avail-
able), and fall back to the third if not:
<prefer-server id="00:03:00:01:02:03:04:05:06:07" weight="never" />
<prefer-server ip="2001:DB8::1" weight="always" />
<prefer-server ip="2001:DB8::2" weight="50" />
allow-update
Specify the list of system services that wicked will configure
based on the DHCP lease received. For the syntax of this ele-
ment, please refer to the description of default-allow-update
above. DHCPv6 allows the following update facilities:
+---------+---------------------------------------------------------------------+
|Name | Description |
+---------+---------------------------------------------------------------------+
|hostname | system hostname (fqdn) |
|dns | update resolv.conf or dns server (via netconfig) |
|ntp | NTP servers (via netconfig) |
|sip | SIP client (optional, no netconfig module implemented) |
|nis | NIS client (optional, no netconfig module, not supported by ypbind) |
|tz | posix time zone (no netconfig module implemented) |
|boot | boot-url used in the initrd |
+---------+---------------------------------------------------------------------+
Note: DHCPv6 protocol does not provide any options to request
routing settings, which are applied via a router advertisement
(IPv6 RA).
define Permits to define list of custom dhcp options not covered by
wicked yet. The dhcp6 option codes are 16-bit (1..65534) inte-
gers.
See http://www.iana.org/assignments/dhcpv6-parameters and
RFC7227.
To request support for a specific standard option, issue a fea-
ture request at https://fate.suse.com/ or https://features.open-
suse.org/ (hermes). See CUSTOM DHCP OPTIONS section for more
details.
Note: The DHCPv6 protocol does not define any routing options, which
are applied by IPv6 Router Advertisement (RA) or require static
configuration. The current NIS / ypbind implementation on linux
does supported IPv6 at all.
CUSTOM DHCP OPTIONS
A custom option defines a name for a dhcp option code and a format how
to interpret raw data of the dhcp option. This option definition is
used to parse and format lease-xml files, (format) leaseinfo dump files
and the name can be used to request options (oro alias option-request-
option).
The name has to be a valid keyword and is restricted to a word of 1..63
alphanumeric and "-" characters (same to a hostname without any dots).
The current implementation supports the following simple types
(scalars):
opaque [fixed-length="<length in bytes>" | embedded-
length="1|2|uint8|uint16"]
Opaque data or not printable string formatted as a hex-string
(xx:xx:xx) with variable length. The fixed-length attribute per-
mits adjust it to a \0 padded fixed-length data field and the
embedded-length attribute to interpret the initial 1 (uint8) or
2 (uint16) bytes as data length (RFC7227).
string [fixed-length="<length in bytes>" | embedded-
length="1|2|uint8|uint16"]
A printable variable-length string (without a \0 null-termina-
tion). The fixed-length attribute permits to adjust it to a \0
padded fixed-length string and the embedded-length attribute to
interpret the initial 1 (uint8) or 2 (uint16) bytes as the
string length (RFC7227).
bool A single byte value interpreted as boolean (0 is "false", other-
wise "true").
int8 | int16 | int32 | int64 uint8 | uint16 | uint32 | uint64 [nota-
tion="hex"]
A signed or unsigned integer in decimal or optionally, in a 0x..
hex notation.
ipv4-address | ipv6-address
IPv4 and IPv6 address types
ipv4-prefix | ipv6-prefix
An RFC3442 / RFC7227 prefix (destination descriptor) with com-
pact encoded prefix-length byte followed by the significant
octets of the network address.
These simple types can be combined together in structs and arrays.
A structs consists of one or more members, which contain a name and a
member type, struct or array. The last member in a struct is allowed to
contain be variable length type. An array contains an element name and
fixed-length type or struct.
A simple type can be specified in the node name (<string/>) or in the
data of the type node (<type>string</type>).
Examples:
<!--
global or device specific definitions of dhcp4/dhcp6 options
under <config><addrconf><dhcp4> or <config><addrconf><dhcp6>
-->
<define>
<option>
<code>224</code>
<name>foo-server</name>
<type>ipv4-address</type>
</option>
<option>
<code>225</code>
<name>foo-path</name>
<string/>
</option>
<option>
<code>250</code>
<name>test-cls-routes</name> <!-- RFC3442 classless route format -->
<array>
<name>route</name>
<struct>
<member>
<name>destination</name>
<ipv4-prefix/>
</member>
<member>
<name>gateway</name>
<ipv4-address/>
</member>
</struct>
</array>
</option>
<option>
<code>251</code>
<name>six-addresses</code>
<array>
<name>ip</name>
<ipv6-address/>
</array>
</option>
</define>
To test the option definition, the "wicked test" call can be used:
wicked test dhcp4 --request - eth1 <<EOF
<request type= offer">
<request-options>
<option>224</option>
<option>test-cls-routes</option>
</request-options>
</request>
EOF
before adding the option requests to the ifcfg or xml configuration and
restarting wickedd ("rcwickedd restart") to apply to the supplicant.
SERVER ONLY OPTIONS
teamd
The <teamd> element permits to enable or disable teamd support
(inclusive discovery of team device details) in its <enable>
sub-element. Disabled by default, server.xml config enables it.
Further, it permits to specify the control interface to communi-
cate with teamd in the <ctl> sub-element, using the following
options:
+------------+-----------------------------------------------------+
|Option | Description |
+------------+-----------------------------------------------------+
|detect-once | detect the control interface to use, once (default) |
|detect | detect the control interface to use in each call |
|dbus | communicate directly with teamd via dbus |
|unix | use unix socket control interface via teamdctl tool |
+------------+-----------------------------------------------------+
bonding
The <bonding> element permits to specify whether to use netlink
or sysfs to configure the bonding in its <ctl> sub-element:
+--------+-------------------------------------------+
|Option | Description |
+--------+-------------------------------------------+
|netlink | configure bonding via netlink (default) |
|sysfs | configure bonding via sysfs (the old way) |
+--------+-------------------------------------------+
EXTENSIONS
The functionality of wickedd can be extended through external commands
and shell scripts. All of these extensions are declared in server.xml,
and all of them follow the same pattern.
Script extensions
Scripts are specified via the <script> element, which needs to
provide a name attribute and a command attribute. Again, the
name serves as an identifier, while the command specifies the
command to be invoked. wicked comes with a (simple) parser for
this, which splits up this command into a argument array which
is passed to execve(2) eventually.
An example would look like this:
<script name="install"
command="/etc/wicked/extensions/hostname install"/>
When defining script extensions, it is possible to define addi-
tional environment variables that get passed to the script. This
mechanism is explained in more detail below.
Extensions are always grouped under a parent element. The following
configuration elements can contain extensions:
System updaters
These specify extensions for managing files like resolv.conf, or the
system hostname, based on information contained through an address con-
figuration protocol like DHCP. The configuration element must have a
name attribute that specifies the system service to configure, and
include extensions for backing up the current configuration, for
installing new settings, and for restoring the backup.
The configuration for the hostname updater might look like this:
<system-updater name= hostname">
<script name="backup" command="/etc/wicked/extensions/hostname backup"/>
<script name="restore" command="/etc/wicked/extensions/hostname restore"/>
<script name="install" command="/etc/wicked/extensions/hostname install"/>
<script name="install" command="/etc/wicked/extensions/hostname remove"/>
</system-updater>
Currently, wicked supports generic and hostname system updaters. The
generic updater operates on data which can be set via netconfig (refer
to netconfig(7). The hostname updater sets the system hostname.
This extension class supports shell scripts only.
Firmware discovery
Some platforms support iBFT or similar mechanisms to provide the con-
figuration for a network device through the firmware (so that it's pos-
sible to boot off that device). In order to support these mechanisms,
wicked supports extensions to discover such configuration through
firmware discovery extensions.
<netif-firmware-discovery>
