 &kdm; master configuration file
 _
 Definition: the greeter is the login dialog, i.e., the part of &kdm;
 which the user sees.
 _
 You can configure every X-display individually.
 Every display has a display name, which consists of a host name
 (which is empty for local displays specified in {Static|Reserve}Servers),
 a colon, and a display number. Additionally, a display belongs to a
 display class (which can be ignored in most cases; the control center
 does not support this feature at all).
 Sections with display-specific settings have the formal syntax
 "[X-" host [":" number [ "_" class ]] "-" sub-section "]"
 You can use the "*" wildcard for host, number, and class. You may omit
 trailing components; they are assumed to be "*" then.
 The host part may be a domain specification like ".inf.tu-dresden.de".
 It may also be "+", which means non-empty, i.e. remote displays only.
 From which section a setting is actually taken is determined by these
 rules:
 - an exact match takes precedence over a partial match (for the host part),
   which in turn takes precedence over a wildcard ("+" taking precedence
   over "*")
 - precedence decreases from left to right for equally exact matches
 Example: display name "myhost:0", class "dpy".
 [X-myhost:0_dpy] precedes
 [X-myhost:0_*] (same as [X-myhost:0]) precedes
 [X-myhost:*_dpy] precedes
 [X-myhost:*_*] (same as [X-myhost]) precedes
 [X-+:0_dpy] precedes
 [X-*:0_dpy] precedes
 [X-*:0_*] (same as [X-*:0]) precedes
 [X-*:*_*] (same as [X-*])
 These sections do NOT match this display:
 [X-hishost], [X-myhost:0_dec], [X-*:1], [X-:*]
 If a setting is not found in any matching section, the default is used.
 _
 Every comment applies to the following section or key. Note that all
 comments will be lost if you change this file with the kcontrol frontend.
 The defaults refer to &kdm;'s built-in values, not anything set in this file.
 _
 Special characters need to be backslash-escaped (leading and trailing
 spaces (\\s), tab (\\t), linefeed (\\n), carriage return (\\r) and the
 backslash itself (\\\\)).
 In lists, fields are separated with commas without whitespace in between.
 Some command strings are subject to simplified sh-style word splitting:
 single quotes (') and double quotes (") have the usual meaning; the backslash
 quotes everything (not only special characters). Note that the backslashes
 need to be doubled because of the two levels of quoting.

[General]

[Xdmcp]

[Shutdown]

 Rough estimations about how many seconds &kdm; will spend at most on
 - opening a connection to the X-server (OpenTime) if the attempt
   - times out: OpenTimeout
   - is refused: OpenRepeat * OpenDelay
 - starting a local X-server (ServerTime):
   ServerAttempts * (ServerTimeout + OpenDelay)
 - starting a display:
   - local display: ServerTime + OpenTime
   - foreign display: StartAttempts * OpenTime
   - &XDMCP; display: OpenTime (repeated indefinitely by client)

<sect1 id="kdmrc-xservers">
<title>Specifying permanent &X-Server;s</title>

<para>Each entry in the <option>StaticServers</option> list indicates a
display which should constantly be
managed and which is not using &XDMCP;. This method is typically used only for
local &X-Server;s that are started by &kdm;, but &kdm; can manage externally
started (<quote>foreign</quote>) &X-Server;s as well, may they run on the 
local machine or rather remotely.</para>

<para>The formal syntax of a specification is
<screen>
<userinput><replaceable>display&nbsp;name</replaceable>&nbsp;[<literal>_</literal><replaceable>display&nbsp;class</replaceable>]</userinput>
</screen>
for all &X-Server;s. <quote>Foreign</quote> displays differ in having
a host name in the display name, may it be <literal>localhost</literal>.</para>

<para>The <replaceable>display name</replaceable> must be something that can
be passed in the <option>-display</option> option to an X program. This string
is used to generate the display-specific section names, so be careful to match
the names.
The display name of &XDMCP; displays is derived from the display's address by
reverse host name resolution. For configuration purposes, the
<literal>localhost</literal> prefix from locally running &XDMCP; displays is
<emphasis>not</emphasis> stripped to make them distinguishable from local
&X-Server;s started by &kdm;.</para>

<para>The <replaceable>display class</replaceable> portion is also used in the
display-specific sections. This is useful if you have a large collection of
similar displays (such as a corral of X terminals) and would like to set
options for groups of them.
When using &XDMCP;, the display is required to specify the display class,
so the manual for your particular X terminal should document the display
class string for your device. If it does not, you can run &kdm; in debug
mode and <command>grep</command> the log for <quote>class</quote>.</para>

<para>The displays specified in <option>ReserveServers</option> will not be
started when &kdm; starts up, but when it is explicitly requested via
the command socket.
If reserve displays are specified, the &kde; menu will have a
<guilabel>Start New Session</guilabel> item near the bottom; use that to
activate a reserve display with a new login session. The monitor will switch
to the new display, and you will have a minute to login. If there are no more
reserve displays available, the menu item will be disabled.</para>

<para>When &kdm; starts a session, it sets up authorization data for the
&X-Server;. For local servers, &kdm; passes
<command><option>-auth</option>&nbsp;<filename><replaceable>filename</replaceable></filename></command>
on the &X-Server;'s command line to point it at its authorization data.
For &XDMCP; displays, &kdm; passes the authorization data to the &X-Server;
via the <quote>Accept</quote> &XDMCP; message.</para>

</sect1>

<sect1 id="kdmrc-xaccess">
<title>&XDMCP; access control</title>

<para>The file specified by the <option>AccessFile</option> option provides
information which &kdm; uses to control access from displays requesting service
via &XDMCP;.
The file contains four types of entries: entries which control the response
to <quote>Direct</quote> and <quote>Broadcast</quote> queries, entries which
control the response to <quote>Indirect</quote> queries, macro definitions,
and entries which control on which network interfaces &kdm; listens for &XDMCP;
queries.
Blank lines are ignored, <literal>#</literal> is treated as a comment
delimiter causing the rest of that line to be ignored, and <literal>\</literal>
causes an immediately following newline to be ignored, allowing host lists
to span multiple lines.
</para>

<para>The format of the <quote>Direct</quote> entries is simple, either a
host name or a pattern, which is compared against the host name of the display
device. Alternatively, a macro may be used to make the entry match everything
the macro expands to.
Patterns are distinguished from host names by the inclusion of one or more
meta characters; <literal>*</literal> matches any sequence of 0 or more
characters, and <literal>?</literal> matches any single character.
If the entry is a host name, all comparisons are done using network addresses,
so any name which converts to the correct network address may be used. Note
that only the first network address returned for a host name is used.
For patterns, only canonical host names are used in the comparison, so ensure
that you do not attempt to match aliases.
Host names from &XDMCP; queries always contain the local domain name
even if the reverse lookup returns a short name, so you can use
patterns for the local domain.
Preceding the entry with a <literal>!</literal> character causes hosts which
match that entry to be excluded. Preceding it with an <literal>=</literal> has
no effect but is required when specifying a macro to distinguish the entry
from a macro definition.
To only respond to <quote>Direct</quote> queries for a host or pattern,
it can be followed by the optional <literal>NOBROADCAST</literal> keyword.
This can be used to prevent a &kdm; server from appearing on menus based on
<quote>Broadcast</quote> queries.</para>

<para>An <quote>Indirect</quote> entry also contains a host name, pattern or
macro, but follows it with a list of host names or macros to which the queries
should be forwarded. <quote>Indirect</quote> entries can be excluding as well,
in which case a (valid) dummy host name must be supplied to make the entry
distinguishable from a <quote>Direct</quote> entry.
If compiled with IPv6 support, multicast address groups may also be included
in the list of addresses the queries are forwarded to.
<!-- Not actually implemented!
Multicast addresses may be followed by an optional <literal>/</literal>
character and hop count. If no hop count is specified, the multicast hop count
defaults to 1, keeping the packet on the local network. For IPv4 multicasting,
the hop count is used as the TTL.
-->
If the indirect host list contains the keyword <literal>CHOOSER</literal>,
<quote>Indirect</quote> queries are not forwarded, but instead a host chooser
dialog is displayed by &kdm;. The chooser will send a <quote>Direct</quote>
query to each of the remaining host names in the list and offer a menu of
all the hosts that respond. The host list may contain the keyword
<literal>BROADCAST</literal>, to make the chooser send a
<quote>Broadcast</quote> query as well; note that on some operating systems,
UDP packets cannot be broadcast, so this feature will not work.
</para>

<para>When checking access for a particular display host, each entry is scanned
in turn and the first matching entry determines the response.
<quote>Direct</quote> and <quote>Broadcast</quote> entries are ignored when
scanning for an <quote>Indirect</quote> entry and vice-versa.</para>

<para>A macro definition contains a macro name and a list of host names and
other macros that the macro expands to. To distinguish macros from hostnames,
macro names start with a <literal>%</literal> character.</para>

<para>The last entry type is the <literal>LISTEN</literal> directive.
The formal syntax is
<screen>
<userinput>&nbsp;<literal>LISTEN</literal>&nbsp;[<replaceable>interface</replaceable>&nbsp;[<replaceable>multicast&nbsp;list</replaceable>]]</userinput>
</screen>
If one or more <literal>LISTEN</literal> lines are specified, &kdm; listens
for &XDMCP; requests only on the specified interfaces.
<replaceable>interface</replaceable> may be a hostname or IP address
representing a network interface on this machine, or the wildcard
<literal>*</literal> to represent all available network interfaces.
If multicast group addresses are listed on a <literal>LISTEN</literal> line,
&kdm; joins the multicast groups on the given interface. For IPv6 multicasts,
the IANA has assigned ff0<replaceable>X</replaceable>:0:0:0:0:0:0:12b as the
permanently assigned range of multicast addresses for &XDMCP;. The
<replaceable>X</replaceable> in the prefix may be replaced by any valid scope
identifier, such as 1 for Node-Local, 2 for Link-Local, 5 for Site-Local, and
so on (see IETF RFC 2373 or its replacement for further details and scope
definitions). &kdm; defaults to listening on the Link-Local scope address
ff02:0:0:0:0:0:0:12b to most closely match the IPv4 subnet broadcast behavior. 
If no <literal>LISTEN</literal> lines are given, &kdm; listens on all
interfaces and joins the default &XDMCP; IPv6 multicast group (when
compiled with IPv6 support).
To disable listening for &XDMCP; requests altogether, a
<literal>LISTEN</literal> line with no addresses may be specified, but using
the <literal>[Xdmcp]</literal> <option>Enable</option> option is preferred.
</para>

<para>
The following programs are run by &kdm; at various stages of a session.

<para>
The Setup, Startup and Reset programs are run as
<systemitem class="username">root</systemitem>, so they should be careful

# The rest of this file are section and key definitions for the options.
# The order of the keywords is fixed and everything is case sensitive.
# A keyword may expect supplementary data in the form of space-indented
# lines following it. Definitions are delimited by empty lines.
#
# Section definition:
#   Section: <name>
#     Section name. Section classes start with a dash.
#   If: <expression>
#     C preprocessor conditional for supporting this section.
#     If it evaluates to false, all keys in this section are disabled as well.
#   Description:
#     A docbook description of this section is expected in the next lines.
#     The contents are automatically enclosed in <para></para>.
#
# Option key definition:
#   Key: <name>
#     Option name.
#   If: <expression>
#     C preprocessor conditional for supporting this option.
#   Type: (int|bool|enum|group|string|path|list)
#     The option's data type.
#     If the type is enum, the element definitions follow in the next lines:
#       <term>[/<c #define>]: <docbook style description>
#   Default: <default>
#     Default value. string, path and list are copied verbatim and therefore
#     must be already quoted appropriately. The other types are auto-quoted.
#     If the default value is prefixed with a "*", a c #define def_<Key> is
#     created.
#     The default is automatically appended to the kdmrc comment and the
#     documentation entry.
#   CDefault: <verbose default>
#     Append this instead of the real default to the two docs. The quoting
#     rules are the same as for Default.
#   DDefault: -
#     If specified, the default value will not be appended to the documentation
#     entry. The Description should mention the default then. Use this when
#     the default is system-dependent.
#   PostProc: <function>
#     A function to postprocess the read config value before using it.
#   User: (dummy|(core|greeter|greeter-c|dep|config)[(<variable>)][:font])
#     These entries specify which parts of kdm need the option in question:
#       dummy: no user; entry is there only for syntactical correctness.
#       dep: this option is an internal dependency for another option.
#       config: this option configures the config reader itself.
#       core: the kdm backend needs this option.
#       greeter-c: the kdm frontend needs this option as a C data type.
#       greeter: the kdm frontend needs this option as a C++/Qt data type.
#         If a :font tag is appended, a string entry is converted to a QFont.
#     If no variable name is specified, it will be derived from the Key by
#     un-capitalizing it.
#   Instance: (-|[#][<display spec>/](!|<value>))
#     These entries specify option instances for the default/example kdmrc.
#     A "-" entry is a dummy for syntactical correctness.
#     A prefixing hash mark will be copied to kdmrc.
#     For options in a section class a display must be specified.
#     For bool options "!" can be used as the value to specify the negation
#     of the default.
#   Update: <function>[/<number>]
#     Call this function on each occurence of this option in genkdmconf.
#     Options with higher numbers (default is 0) will be processed later.
#   Merge: xdm[:<resource>][(<function>)]
#   Merge: kdm:[<section>/][<key>][(<function>)]
#     Specify config options to merge from xdm and older kdm versions.
#     Kdm options from the current version are automatically merged.
#     When merging an xdm resource and no resource name is specified, it is
#     derived from the Key by un-capitalizing it.
#     When merging a kdm option, at least one of <section> and <key> must
#     be given; an unspecified entity defaults to the current Section/Key.
#     <section> may be a dash-prefixed section class.
#     A function to postprocess the read value can be specified.
#   Comment: [&|-]
#     A kdmrc comment for this option is expected in the next lines.
#     If "-" is given to Comment, no comment is generated at all.
#     If "&" is given, the comment is derived from the Description below by
#     applying some simple docbook interpretation to it. Note that the
#     Description must be preformatted in this case. Use
#        sed -ne 's/^\(.\{79,\}\)$/\1/p' < kdmrc
#     after running "make install" to see whether all lines still fit.
#     If Type is enum, a list of the previously defined element/description
#     pairs is appended; the descriptions undergo docbook interpretation.
#     Finally, a sentence with the Default (or CDefault, if given) is appended.
#   Description: [!|-]
#     A docbook description of this option is expected in the next lines.
#     The contents are automatically enclosed in <para></para>.
#     If "-" is given to Description, no comment is generated at all.
#     If "!" is given, enums are not treated specially; otherwise, the macro
#     %ENUM% is replaced with a list of the defined element/description pairs,
#     or - if the macro is not present - the list is appended to the
#     description.
#     Finally, a sentence with the Default (or CDefault, if given) is appended,
#     unless "DDefault: -" was specified.
#     Each option entry generates an anchor named option-<lowercase(Key)>;
#     it can be referenced in the main documentation.
#     Do not forget to run "make ref" in kdebase/doc/kdm after changing
#     Descriptions.

Merge: xdm
Comment:
 Strip domain name from remote display names if it is equal to the local
 domain.
Description:
 When computing the display name for &XDMCP; clients, the name resolver will
 typically create a fully qualified host name for the terminal. As this is
 sometimes confusing, &kdm; will remove the domain name portion of the host
 name if it is the same as the domain name of the local host when this option
 is enabled.

Key: SourceAddress
Type: bool
Default: false
User: core
Instance: #!
Merge: xdm
Comment:
 Use the numeric IP address of the incoming connection on multihomed hosts
 instead of the host name.

Comment:
 The VT the &X-Server; should run on; auto-assign if zero, don't assign if -1.
 Better leave it zero and use ServerVTs.
Description:
 The VT the &X-Server; should run on.
 <option>ServerVTs</option> should be used instead of this option.
 Leave it zero to let &kdm; assign a <acronym>VT</acronym> automatically.
 Set it to <literal>-1</literal> to avoid assigning a <acronym>VT</acronym>
 alltogether - this is required for setups with multiple physical consoles.
 Currently Linux only.

Key: ServerTTY

 the terminal does not respond, the session is declared dead and terminated.
 </para><para>
 If you frequently use X terminals which can become isolated from
 the managing host, you may wish to increase the timeout. The only worry
 is that sessions will continue to exist after the terminal has been
 accidentally disabled.

 Need to reset the &X-Server; to make it read initial Xauth file.
Description:
 Some <emphasis>old</emphasis> &X-Server;s re-read the authorization file
 at &X-Server; reset time, instead of when checking the initial connection.
 As &kdm; generates the authorization information just before connecting to
 the display, an old &X-Server; would not get up-to-date authorization
 information. This option causes &kdm; to send SIGHUP to the &X-Server;
 after setting up the file, causing an additional &X-Server; reset to occur,
 during which time the new authorization information will be read.

Comment:
 Hold the &X-Server; grabbed the whole time the greeter is visible. This
 may be more secure, but it will disable any background and other
 X-clients started from the Setup script.
Description:
 To improve security, the greeter grabs the &X-Server; and then the keyboard
 when it starts up. This option specifies if the &X-Server; grab should be held
 for the duration of the name/password reading. When disabled, the &X-Server;
 is ungrabbed after the keyboard grab succeeds; otherwise, the &X-Server; is
 grabbed until just before the session begins.

Key: GrabTimeout
Type: int

User: greeter

Comment:
 How many seconds to wait for grab to succeed.
Description:
 This option specifies the maximum time &kdm; will wait for the grabs to
 succeed. A grab may fail if some other X-client has the &X-Server; or the
 keyboard grabbed, or possibly if the network latencies are very high. You
 should be cautious when raising the timeout, as a user can be spoofed by
 a look-alike window on the display. If a grab fails, &kdm; kills and
 restarts the &X-Server; (if possible) and the session.
