<title>Semantics</title>
|
||
|
||
<para>The <varname>StaticHostname</varname> property exposes the "static" hostname configured in
|
||
<filename>/etc/hostname</filename>. It is not always in sync with the current hostname as returned by the
|
||
<citerefentry project="man-pages"><refentrytitle>gethostname</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
||
system call. If no static hostname is configured this property will be the empty string.</para>
|
||
|
||
<para>When <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry> or
|
||
<citerefentry><refentrytitle>systemd-hostnamed.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
||
set the hostname, this static hostname <emphasis>has the highest priority</emphasis>.</para>
|
||
|
||
<para>The <varname>Hostname</varname> property exposes the actual hostname configured in the kernel via
|
||
<citerefentry project="man-pages"><refentrytitle>sethostname</refentrytitle><manvolnum>2</manvolnum></citerefentry>.
|
||
It can be different from the static hostname. This property is never empty.</para>
|
||
|
||
<para>The <varname>PrettyHostname</varname> property exposes the <emphasis>pretty hostname</emphasis>
|
||
which is a free-form UTF-8 hostname for presentation to the user. User interfaces should ensure that the
|
||
pretty hostname and the static hostname stay in sync. E.g. when the former is <literal>Lennart’s
|
||
Computer</literal> the latter should be <literal>lennarts-computer</literal>. If no pretty hostname is
|
||
set this setting will be the empty string. Applications should then find a suitable fallback, such as the
|
||
dynamic hostname.</para>
|
||
|
||
<para>The <varname>DefaultHostname</varname> property exposes the default hostname (configured through
|
||
<citerefentry><refentrytitle>os-release</refentrytitle><manvolnum>5</manvolnum></citerefentry>, or a
|
||
fallback set at compilation time).</para>
|
||
|
||
<para>The <varname>HostnameSource</varname> property exposes the origin of the currently configured
|
||
hostname. One of <literal>static</literal> (set from <filename>/etc/hostname</filename>),
|
||
<literal>transient</literal> (a non-permanent hostname from an external source),
|
||
<literal>default</literal> (the value from <filename>os-release</filename> or the compiled-in
|
||
fallback).</para>
|
||
|
||
<para>The <varname>IconName</varname> property exposes the <emphasis>icon name</emphasis> following the
|
||
XDG icon naming spec. If not set, information such as the chassis type (see below) is used to find a
|
||
suitable fallback icon name (i.e. <literal>computer-laptop</literal>
|
||
vs. <literal>computer-desktop</literal> is picked based on the chassis information). If no such data is
|
||
available, the empty string is returned. In that case an application should fall back to a replacement
|
||
icon, for example <literal>computer</literal>. If this property is set to the empty string, the automatic
|
||
fallback name selection is enabled again.</para>
|
||
|
||
<para>The <varname>Chassis</varname> property exposes a <emphasis>chassis type</emphasis>, one of the
|
||
currently defined chassis types: <literal>desktop</literal>, <literal>laptop</literal>,
|
||
<literal>server</literal>, <literal>tablet</literal>, <literal>handset</literal>, as well as the special
|
||
chassis types <literal>vm</literal> and <literal>container</literal> for virtualized systems. Note that
|
||
in most cases the chassis type will be determined automatically from DMI/SMBIOS/ACPI firmware
|
||
information. Writing to this setting is hence useful only to override misdetected chassis types, or to
|
||
configure the chassis type if it could not be auto-detected. Set this property to the empty string to
|
||
reenable the automatic detection of the chassis type from firmware information.</para>
|
||
|
||
<para>Note that <filename>systemd-hostnamed</filename> starts only on request and terminates after a
|
||
short idle period. This effectively means that <function>PropertyChanged</function> messages are not sent
|
||
out for changes made directly on the files (as in: administrator edits the files with vi). This is
|
||
the intended behavior: manual configuration changes should require manual reloading.</para>
|
||
|
||
<para>The transient (dynamic) hostname exposed by the <varname>Hostname</varname> property maps directly
|
||
to the kernel hostname. This hostname should be assumed to be highly dynamic, and hence should be watched
|
||
directly, without depending on <function>PropertyChanged</function> messages from
|
||
<filename>systemd-hostnamed</filename>. To accomplish this, open
|
||
<filename>/proc/sys/kernel/hostname</filename> and
|
||
<citerefentry project="man-pages"><refentrytitle>poll</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
||
for <constant>SIGHUP</constant> which is triggered by the kernel every time the hostname changes. Again:
|
||
this is special for the transient (dynamic) hostname, and does not apply to the configured (fixed)
|
||
hostname.</para>
|
||
|
||
<para>Applications may read the hostname data directly if hostname change notifications
|
||
are not necessary. Use
|
||
<citerefentry project="man-pages"><refentrytitle>gethostname</refentrytitle><manvolnum>2</manvolnum></citerefentry>,
|
||
<filename>/etc/hostname</filename> (possibly with per-distribution fallbacks), and
|
||
<citerefentry><refentrytitle>machine-info</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
||
for that. For more information on these files and syscalls see the respective man pages.</para>
|
||
|
||
<para><varname>KernelName</varname>, <varname>KernelRelease</varname>, and
|
||
<varname>KernelVersion</varname> expose the kernel name (e.g. <literal>Linux</literal>), release
|
||
(e.g. <literal>5.0.0-11</literal>), and version (i.e. the build number, e.g. <literal>#11</literal>) as
|
||
reported by <citerefentry project="man-pages"><refentrytitle>uname</refentrytitle><manvolnum>2</manvolnum></citerefentry>.
|
||
<varname>OperatingSystemPrettyName</varname>, <varname>OperatingSystemCPEName</varname>, and
|
||
<varname>HomeURL</varname> expose the <varname>PRETTY_NAME=</varname>, <varname>CPE_NAME=</varname> and
|
||
<varname>HOME_URL=</varname> fields from
|
||
<citerefentry><refentrytitle>os-release</refentrytitle><manvolnum>5</manvolnum></citerefentry>. The
|
||
purpose of those properties is to allow remote clients to access this information over D-Bus. Local
|

clients can access the information directly.</para>
|
||
|
||
<para><varname>MachineID</varname> expose the 128bit machine ID, see

|
||
details.</para>
|

<filename>/proc/sys/kernel/random/boot_id</filename>.</para>
|

<para><varname>VSockCID</varname> exposes the system's local <constant>AF_VSOCK</constant> CID (Context

Identifier, i.e. address) for the system, if one is available in the virtual machine environment. Set to

<constant>UINT32_MAX</constant> otherwise. See <citerefentry project="man-pages"><refentrytitle>vsock</refentrytitle><manvolnum>7</manvolnum></citerefentry> for
|

details.</para>
|
||
|
||
<para><varname>OperatingSystemSupportEnd</varname> exposes when the OS' vendor support ends, if this
|

information is known. It's an unsigned 64bit value, in µs since the UNIX epoch, UTC. If this information
|
||
is not known carries the value 2^64-1, i.e. <constant>UINT64_MAX</constant>.</para>
|
||
|
||
<para><varname>HardwareVendor</varname> and <varname>HardwareModel</varname> expose information about the

vendor of the hardware of the system. If no such information can be determined these properties are set
|

to empty strings.</para>
|
||
|

<para><varname>FirmwareVersion</varname> and <varname>FirmwareVendor</varname> expose information about
|

the system's firmware, i.e. a version string and a vendor name. If no such information can be determined
|

these properties are set to empty strings.</para>
|
||
|
||
<para><varname>FirmwareDate</varname> exposes the firmware build date, if that information is known. It's

<title>Methods</title>
|
||
|

<para><function>SetHostname()</function> sets the transient (dynamic) hostname, which is used if no

static hostname is set. This value must be an internet-style hostname, 7-bit lowercase ASCII, no
|
||
special chars/spaces. An empty string will unset the transient hostname.</para>
|
||
|
||
<para><function>SetStaticHostname()</function> sets the static hostname which is exposed by the
|
||
<varname>StaticHostname</varname> property. When called with an empty argument, the static
|

configuration in <filename>/etc/hostname</filename> is removed. Since the static hostname has the
|

highest priority, calling this function usually affects also the <varname>Hostname</varname> property
|

and the effective hostname configured in the kernel.</para>
|

<title>Recommendations</title>

|
||
<para>Here are three examples that show how the pretty hostname and the icon name should be used:
|
||
<itemizedlist>
|
||
<listitem><para>When registering DNS-SD services: use the pretty hostname in the service name, and pass
|
||
the icon name in the TXT data, if there is an icon name. Browsing clients can then show the server icon
|
||
on each service. This is especially useful for WebDAV applications or UPnP media sharing.
|
||
</para></listitem>
|
||
|
||
<listitem><para>Set the bluetooth name to the pretty hostname.</para></listitem>
|
||
|
||
<listitem><para>When your file browser has a "Computer" icon, replace the name with the pretty hostname
|
||
if set, and the icon with the icon name, if it is set.</para></listitem>
|
||
</itemizedlist></para>
|
||
|
||
<para>To properly handle name lookups with changing local hostnames without having to edit
|
||
<filename>/etc/hosts</filename>, we recommend using <filename>systemd-hostnamed</filename> in combination
|
||
with <citerefentry><refentrytitle>nss-myhostname</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
|
||
</para>
|
||
|
||
<para>Here are some recommendations to follow when generating a static (internet) hostname from a pretty
|
||
name:
|
||
<itemizedlist>
|
||
<listitem><para>Generate a single DNS label only, not an FQDN. That means no dots allowed. Strip them,
|
||
or replace them with <literal>-</literal>.</para></listitem>
|
||
|
||
<listitem><para>It's probably safer to not use any non-ASCII chars, even if DNS allows this in some way
|
||
these days. In fact, restrict your charset to <literal>a-zA-Z0-9</literal> and <literal>-</literal>.
|
||
Strip other chars, or try to replace them in some smart way with chars from this set, for example

<para>Note that while <filename>systemd-hostnamed</filename> applies some checks to the hostname you pass
|
||
they are much looser than the recommendations above. For example, <filename>systemd-hostnamed</filename>
|
||
will also accept <literal>_</literal> in the hostname, but we recommend not using this to avoid clashes
|
||
with DNS-SD service types. Also <filename>systemd-hostnamed</filename> allows longer hostnames, but
|
||
because of the DNS label limitations, we recommend not making use of this.</para>

<para>Of course, an already valid internet hostname label you enter and pass through this

conversion should stay unmodified, so that users have direct control of it, if they want — by simply

ignoring the fact that the pretty hostname is pretty and just edit it as if it was the normal internet
