88 &kdm; master configuration file
90 Definition: the greeter is the login dialog, i.e., the part of &kdm;
91 which the user sees.
93 You can configure every X-display individually.
94 Every display has a display name, which consists of a host name
95 (which is empty for local displays specified in {Static|Reserve}Servers),
96 a colon, and a display number. Additionally, a display belongs to a
97 display class (which can be ignored in most cases; the control center
98 does not support this feature at all).
99 Sections with display-specific settings have the formal syntax
100 "[X-" host [":" number [ "_" class ]] "-" sub-section "]"
101 You can use the "*" wildcard for host, number, and class. You may omit
102 trailing components; they are assumed to be "*" then.
103 The host part may be a domain specification like ".inf.tu-dresden.de".
104 It may also be "+", which means non-empty, i.e. remote displays only.
105 From which section a setting is actually taken is determined by these
106 rules:
107 - an exact match takes precedence over a partial match (for the host part),
108 which in turn takes precedence over a wildcard ("+" taking precedence
109 over "*")
110 - precedence decreases from left to right for equally exact matches
111 Example: display name "myhost:0", class "dpy".
112 [X-myhost:0_dpy] precedes
113 [X-myhost:0_*] (same as [X-myhost:0]) precedes
114 [X-myhost:*_dpy] precedes
115 [X-myhost:*_*] (same as [X-myhost]) precedes
116 [X-+:0_dpy] precedes
117 [X-*:0_dpy] precedes
118 [X-*:0_*] (same as [X-*:0]) precedes
119 [X-*:*_*] (same as [X-*])
120 These sections do NOT match this display:
121 [X-hishost], [X-myhost:0_dec], [X-*:1], [X-:*]
122 If a setting is not found in any matching section, the default is used.
124 Every comment applies to the following section or key. Note that all
125 comments will be lost if you change this file with the kcontrol frontend.
126 The defaults refer to &kdm;'s built-in values, not anything set in this file.
128 Special characters need to be backslash-escaped (leading and trailing
129 spaces (\\s), tab (\\t), linefeed (\\n), carriage return (\\r) and the
130 backslash itself (\\\\)).
131 In lists, fields are separated with commas without whitespace in between.
132 Some command strings are subject to simplified sh-style word splitting:
133 single quotes (') and double quotes (") have the usual meaning; the backslash
134 quotes everything (not only special characters). Note that the backslashes
135 need to be doubled because of the two levels of quoting.
137 [General]
139 [Xdmcp]
141 [Shutdown]
143 Rough estimations about how many seconds &kdm; will spend at most on
144 - opening a connection to the X-server (OpenTime) if the attempt
145 - times out: OpenTimeout
146 - is refused: OpenRepeat * OpenDelay
147 - starting a local X-server (ServerTime):
148 ServerAttempts * (ServerTimeout + OpenDelay)
149 - starting a display:
150 - local display: ServerTime + OpenTime
151 - foreign display: StartAttempts * OpenTime
152 - &XDMCP; display: OpenTime (repeated indefinitely by client)

310 <title>Specifying permanent &X-Server;s</title>
312 <para>Each entry in the <option>StaticServers</option> list indicates a
313 display which should constantly be
314 managed and which is not using &XDMCP;. This method is typically used only for
315 local &X-Server;s that are started by &kdm;, but &kdm; can manage externally
316 started (<quote>foreign</quote>) &X-Server;s as well, may they run on the
317 local machine or rather remotely.</para>
319 <para>The formal syntax of a specification is
320 <screen>
321 <userinput><replaceable>display&nbsp;name</replaceable>&nbsp;[<literal>_</literal><replaceable>display&nbsp;class</replaceable>]</userinput>
322 </screen>
323 for all &X-Server;s. <quote>Foreign</quote> displays differ in having
324 a host name in the display name, may it be <literal>localhost</literal>.</para>
326 <para>The <replaceable>display name</replaceable> must be something that can
327 be passed in the <option>-display</option> option to an X program. This string
328 is used to generate the display-specific section names, so be careful to match
329 the names.
330 The display name of &XDMCP; displays is derived from the display's address by
331 reverse host name resolution. For configuration purposes, the
332 <literal>localhost</literal> prefix from locally running &XDMCP; displays is
333 <emphasis>not</emphasis> stripped to make them distinguishable from local
334 &X-Server;s started by &kdm;.</para>
336 <para>The <replaceable>display class</replaceable> portion is also used in the
337 display-specific sections. This is useful if you have a large collection of
338 similar displays (such as a corral of X terminals) and would like to set
339 options for groups of them.
340 When using &XDMCP;, the display is required to specify the display class,
341 so the manual for your particular X terminal should document the display
342 class string for your device. If it does not, you can run &kdm; in debug
343 mode and <command>grep</command> the log for <quote>class</quote>.</para>
345 <para>The displays specified in <option>ReserveServers</option> will not be
346 started when &kdm; starts up, but when it is explicitly requested via
347 the command socket.
348 If reserve displays are specified, the &kde; menu will have a
349 <guilabel>Start New Session</guilabel> item near the bottom; use that to
350 activate a reserve display with a new login session. The monitor will switch
351 to the new display, and you will have a minute to login. If there are no more
352 reserve displays available, the menu item will be disabled.</para>
354 <para>When &kdm; starts a session, it sets up authorization data for the
355 &X-Server;. For local servers, &kdm; passes
356 <command><option>-auth</option>&nbsp;<filename><replaceable>filename</replaceable></filename></command>
357 on the &X-Server;'s command line to point it at its authorization data.
358 For &XDMCP; displays, &kdm; passes the authorization data to the &X-Server;
359 via the <quote>Accept</quote> &XDMCP; message.</para>
361 </sect1>
363 <sect1 id="kdmrc-xaccess">
364 <title>&XDMCP; access control</title>
366 <para>The file specified by the <option>AccessFile</option> option provides
367 information which &kdm; uses to control access from displays requesting service
368 via &XDMCP;.
369 The file contains four types of entries: entries which control the response
370 to <quote>Direct</quote> and <quote>Broadcast</quote> queries, entries which
371 control the response to <quote>Indirect</quote> queries, macro definitions,
372 and entries which control on which network interfaces &kdm; listens for &XDMCP;
373 queries.
374 Blank lines are ignored, <literal>#</literal> is treated as a comment
375 delimiter causing the rest of that line to be ignored, and <literal>\</literal>
376 causes an immediately following newline to be ignored, allowing host lists
377 to span multiple lines.
378 </para>
380 <para>The format of the <quote>Direct</quote> entries is simple, either a
381 host name or a pattern, which is compared against the host name of the display
382 device. Alternatively, a macro may be used to make the entry match everything
383 the macro expands to.
384 Patterns are distinguished from host names by the inclusion of one or more
385 meta characters; <literal>*</literal> matches any sequence of 0 or more
386 characters, and <literal>?</literal> matches any single character.
387 If the entry is a host name, all comparisons are done using network addresses,
388 so any name which converts to the correct network address may be used. Note
389 that only the first network address returned for a host name is used.
390 For patterns, only canonical host names are used in the comparison, so ensure
391 that you do not attempt to match aliases.
392 Host names from &XDMCP; queries always contain the local domain name
393 even if the reverse lookup returns a short name, so you can use
394 patterns for the local domain.
395 Preceding the entry with a <literal>!</literal> character causes hosts which
396 match that entry to be excluded. Preceding it with an <literal>=</literal> has
397 no effect but is required when specifying a macro to distinguish the entry
398 from a macro definition.
399 To only respond to <quote>Direct</quote> queries for a host or pattern,
400 it can be followed by the optional <literal>NOBROADCAST</literal> keyword.
401 This can be used to prevent a &kdm; server from appearing on menus based on
402 <quote>Broadcast</quote> queries.</para>
404 <para>An <quote>Indirect</quote> entry also contains a host name, pattern or
405 macro, but follows it with a list of host names or macros to which the queries
406 should be forwarded. <quote>Indirect</quote> entries can be excluding as well,
407 in which case a (valid) dummy host name must be supplied to make the entry
408 distinguishable from a <quote>Direct</quote> entry.
409 If compiled with IPv6 support, multicast address groups may also be included
410 in the list of addresses the queries are forwarded to.
411 <!-- Not actually implemented!
412 Multicast addresses may be followed by an optional <literal>/</literal>
413 character and hop count. If no hop count is specified, the multicast hop count
414 defaults to 1, keeping the packet on the local network. For IPv4 multicasting,
415 the hop count is used as the TTL.
417 If the indirect host list contains the keyword <literal>CHOOSER</literal>,
418 <quote>Indirect</quote> queries are not forwarded, but instead a host chooser
419 dialog is displayed by &kdm;. The chooser will send a <quote>Direct</quote>
420 query to each of the remaining host names in the list and offer a menu of
421 all the hosts that respond. The host list may contain the keyword
422 <literal>BROADCAST</literal>, to make the chooser send a
423 <quote>Broadcast</quote> query as well; note that on some operating systems,
424 UDP packets cannot be broadcast, so this feature will not work.
425 </para>
427 <para>When checking access for a particular display host, each entry is scanned
428 in turn and the first matching entry determines the response.
429 <quote>Direct</quote> and <quote>Broadcast</quote> entries are ignored when
430 scanning for an <quote>Indirect</quote> entry and vice-versa.</para>
432 <para>A macro definition contains a macro name and a list of host names and
433 other macros that the macro expands to. To distinguish macros from hostnames,
434 macro names start with a <literal>%</literal> character.</para>
436 <para>The last entry type is the <literal>LISTEN</literal> directive.
437 The formal syntax is
438 <screen>
439 <userinput>&nbsp;<literal>LISTEN</literal>&nbsp;[<replaceable>interface</replaceable>&nbsp;[<replaceable>multicast&nbsp;list</replaceable>]]</userinput>
440 </screen>
441 If one or more <literal>LISTEN</literal> lines are specified, &kdm; listens
442 for &XDMCP; requests only on the specified interfaces.
443 <replaceable>interface</replaceable> may be a hostname or IP address
444 representing a network interface on this machine, or the wildcard
445 <literal>*</literal> to represent all available network interfaces.
446 If multicast group addresses are listed on a <literal>LISTEN</literal> line,
447 &kdm; joins the multicast groups on the given interface. For IPv6 multicasts,
448 the IANA has assigned ff0<replaceable>X</replaceable>:0:0:0:0:0:0:12b as the
449 permanently assigned range of multicast addresses for &XDMCP;. The
450 <replaceable>X</replaceable> in the prefix may be replaced by any valid scope
451 identifier, such as 1 for Node-Local, 2 for Link-Local, 5 for Site-Local, and
452 so on (see IETF RFC 2373 or its replacement for further details and scope
453 definitions). &kdm; defaults to listening on the Link-Local scope address
454 ff02:0:0:0:0:0:0:12b to most closely match the IPv4 subnet broadcast behavior.
455 If no <literal>LISTEN</literal> lines are given, &kdm; listens on all
456 interfaces and joins the default &XDMCP; IPv6 multicast group (when
457 compiled with IPv6 support).
458 To disable listening for &XDMCP; requests altogether, a
459 <literal>LISTEN</literal> line with no addresses may be specified, but using
460 the <literal>[Xdmcp]</literal> <option>Enable</option> option is preferred.

1145 typically create a fully qualified host name for the terminal. As this is

2446 To improve security, the greeter grabs the &X-Server; and then the keyboard
2447 when it starts up. This option specifies if the &X-Server; grab should be held

2462 How many seconds to wait for grab to succeed.
2463 Description:
2464 This option specifies the maximum time &kdm; will wait for the grabs to
2465 succeed. A grab may fail if some other X-client has the &X-Server; or the
2466 keyboard grabbed, or possibly if the network latencies are very high. You
2467 should be cautious when raising the timeout, as a user can be spoofed by
2468 a look-alike window on the display. If a grab fails, &kdm; kills and
2469 restarts the &X-Server; (if possible) and the session.
