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.

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 indirect 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. 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. 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 or pattern, 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. If the indirect host list contains the keyword <literal +>CHOOSER</literal +>, <quote +>Indirect</quote +> queries are not forwarded, but instead a host chooser dialogue 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.

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).
