-The purpose of the X Display Manager Control Protocol (XDMCP)
-is to provide a uniform mechanism for an autonomous
-display to request login service from a remote host.
-By autonomous, we mean
-the display consists of hardware and processes that are independent of any
-particular host where login service is desired. (For example, the server
-cannot simply be started by a
-<function>fork/exec</function>
-sequence on the host.)
-An X terminal (screen, keyboard, mouse, processor, network interface)
-is a prime example of an autonomous display.
-</para>
-
-<para>
-From the point of view of the end user, it is very important to make
-autonomous displays as easy to use as traditional hardwired character
-terminals. Specifically, you can typically just power on a hardwired
-terminal and be greeted with a login prompt. The same should be possible
-with autonomous displays. However, in a network environment with multiple
-hosts, the end user may want to choose which host(s) to connect to. In an
-environment with many displays and many hosts, a site administrator may want
-to associate particular collections of hosts with particular displays. We
-would like to support the following options:
-</para>
-
-<itemizedlist>
- <listitem>
- <para>
-The display has a single, fixed host to which it should connect. It should be
-possible to power on the display and receive a login prompt, without user
-intervention.
- </para>
- </listitem>
- <listitem>
- <para>
-Any one of several hosts on a network or subnetwork may be acceptable
-for accepting login from the display.
-(For example, the user's file systems can be mounted onto
-any such host, providing comparable environments.) It should be possible
-for the display to broadcast to find such hosts and to have the display
-either automatically choose a host or present the possible hosts to the
-user for selection.
- </para>
- </listitem>
- <listitem>
- <para>
-The display has a fixed set of hosts that it can connect to. It should be
-possible for the display to have that set stored in RAM, but it should also be
-possible for a site administrator to be able to maintain host sets for a
-large number of displays using a centralized facility, without having to
-interact (physically or electronically) with each individual display.
-Particular hosts should be allowed to refuse login service, based on
-whatever local criteria are desired.
- </para>
- </listitem>
-</itemizedlist>
-
-<para>
-The control protocol should be designed in such a way that it can be used over
-a reasonable variety of communication transport layers. In fact, it is quite
-desirable if every major network protocol family that supports the standard X
-protocol is also capable of supporting XDMCP, because the end result of XDMCP
-negotiation will be standard X protocol connections to the display.
-However, because the number of displays per host may be large,
-a connection-based protocol appears less desirable
-than a connection-less protocol. For this reason the protocol is designed
-to use datagram services with the display responsible for sequencing and
-retransmission.
-</para>
-<para>
-<!-- .LP -->
-To keep the burden on displays at a minimum (because display cost is not
-a factor that can be ignored), it is desirable that displays not be required
-to maintain permanent state (across power cycles) for the purposes
-of the control protocol,
-and it is desirable to keep required state at a minimum while the
-display is powered on.
-</para>
-<para>
-<!-- .LP -->
-Security is an important consideration and must be an integral part of the
-design. The important security goals in the context of XDMCP are:
-</para>
-<itemizedlist>
- <listitem>
- <para>
-It should be possible for the display to verify that it is communicating
-with a legitimate host login service. Because the user will present
-credentials (for example, password) to this service,
-it is important to avoid spoof attacks.
- </para>
- </listitem>
- <listitem>
- <para>
-It should be possible for the display and the login service to negotiate the
-authorization mechanism to be used for the standard X protocol.
- </para>
- </listitem>
- <listitem>
- <para>
-It should be possible to provide the same level of security in verifying the
-login service as is provided by the negotiated authorization mechanism.
- </para>
- </listitem>
- <listitem>
- <para>
-Because there are no firm standards yet in the area of security,
-XDMCP must be flexible enough to accomodate a variety of security mechanisms.

-XDMCP is designed to provide authenticated access to display management
-services for remote displays. A new network server, called a \fIDisplay
-Manager\fP, will use XDMCP to communicate with displays to negotiate the
-startup of X sessions. The protocol allows the display to authenticate the
-manager. It also allows most of the configuration information to be
-centralized with the manager and to ease the burden of system administration
-in a large network of displays.
-The essential goal is to provide plug-and-play
-services similar to those provided in the familiar mainframe/terminal world.

-Displays may be turned off by the user at any time. Any existing session
-running on a display that has been turned off must be identifiable. This
-is made possible by requiring a three-way handshake to start a session. If
-the handshake succeeds, any existing session is terminated immediately and a
-new session started. There is the problem (at least with TCP) that
-connections may not be closed when the display is turned off. In most
-environments, the manager should reduce this problem by periodically XSync'ing
-on its own connection, perhaps every five to ten minutes, and terminating the
-session if its own connection ever closes.

-Displays should not be required to retain permanent state for purposes of
-the control protocol. One solution to packets received out of sequence
-would be to use monotonically increasing message identifiers in each message
-to allow both sides to ignore messages that arrive out-of-sequence. For
-this to work, displays would at a minimum have to increment a stable crash
-count each time they are powered on and use that number as part of a
-larger sequence number. But if displays cannot retain permanent state this
-cannot work. Instead, the manager assumes the responsibility for permanent
-state by generating unique numbers that identify a particular session and
-the protocol simply ignores packets that correspond to an invalid session.
-</para>

-<!-- .LP -->
-The Manager must not be responsible for packet reception. To prevent the
-Manager from becoming stuck because of a hostile display, no portion of the
-protocol requires the Manager to retransmit a packet. Part of this means
-that any valid packet that the Manager does receive must be
-acknowledged in some way to prevent the display from continuously resending
-packets. The display can keep the protocol running as it will always know
-when the Manager has received (at least one copy of) a packet. On the
-Manager side, this means that any packet may be received more than once (if
-the response was lost) and duplicates must be ignored.

-XDMCP packets contain several types of data. Integer values are always
-stored most significant byte first in the packet ("Big Endian" order).
-As XDMCP will not be used to transport large quantities of data, this
-restriction will not substantially hamper the efficiency of any
-implementation. Also, no padding of any sort will occur within the packets.

-If only a single session was active on the display,

-When XDMCP is implemented on top of the Internet User Datagram Protocol (UDP),
-port number 177 is to be used. When using UDP over IPv4, Broadcast Query
-packets are sent via UDP broadcast. When using UDP over IPv6, Broadcast Query
-packets are sent via multicast, either to an address in the IANA registered
-XDMCP multicast address range of
-FF0<emphasis remap='I'>X</emphasis>:0:0:0:0:0:0:12B
-(where the <emphasis remap='I'>X</emphasis> is replaced by a valid scope id)
-or to a locally assigned
-multicast address. The version number in all packets will be 1.
-Packet opcodes are 16-bit integers.

-The Display Class field of the

-The ManufacturerID is a string that should be registered
-with the X Consortium.
-The ModelNumber is designed to identify characteristics of the display
-within the manufacturer's product line.
-This string should be documented in the users manual for the

-The Manufacturer Display ID field of the

-<para>
-In an environment where authentication is not needed, XDMCP can disable
-authentication by having the display send empty Authentication Name
-and Authentication Data fields in the
-<function>Request</function>
-packet.
-In this case, the manager will not attempt to authenticate itself.
-Other authentication protocols may be developed, depending on local needs.
-</para>
-
-<para>
-In an unsecure environment, the display must be able to verify that the
-source of the various packets is a trusted manager. These packets will
-contain authentication information. As an example of such a system, the
-following discussion describes the "XDM-AUTHENTICATION-1" authentication
-system. This system uses a 56-bit shared private key, and 64 bits of
-authentication data. An associated example X authorization protocol
-"XDM-AUTHORIZATION-1" will also be discussed. The 56-bit key is represented
-as a 64-bit number in network order (big endian). This means that the first
-octet in the representation will be zero. When incrementing a 64-bit value,
-the 8 octets of data will be interpreted in network order (big endian).
-That is, the last octet will be incremented, subsequent carries propogate
-towards the first octet.

-The display and manager share a private key. This key could be programmed

(For example, the server +cannot simply be started by a +<function>fork/exec</function> +sequence on the host.) +An X terminal (screen, keyboard, mouse, processor, network interface) +is a prime example of an autonomous display. +</para> + +<para> +From the point of view of the end user, it is very important to make +autonomous displays as easy to use as traditional hardwired character +terminals. Specifically, you can typically just power on a hardwired +terminal and be greeted with a login prompt. The same should be possible +with autonomous displays. However, in a network environment with multiple +hosts, the end user may want to choose which host(s) to connect to. In an +environment with many displays and many hosts, a site administrator may want +to associate particular collections of hosts with particular displays. We +would like to support the following options: +</para> + +<itemizedlist> + <listitem> + <para> +The display has a single, fixed host to which it should connect. It should be +possible to power on the display and receive a login prompt, without user +intervention. + </para> + </listitem> + <listitem> + <para> +Any one of several hosts on a network or subnetwork may be acceptable +for accepting login from the display. +(For example, the user's file systems can be mounted onto +any such host, providing comparable environments.) It should be possible +for the display to broadcast to find such hosts and to have the display +either automatically choose a host or present the possible hosts to the +user for selection. + </para> + </listitem> + <listitem> + <para> +The display has a fixed set of hosts that it can connect to. It should be +possible for the display to have that set stored in RAM, but it should also be +possible for a site administrator to be able to maintain host sets for a +large number of displays using a centralized facility, without having to +interact (physically or electronically) with each individual display. +Particular hosts should be allowed to refuse login service, based on +whatever local criteria are desired. + </para> + </listitem> +</itemizedlist> + +<para> +The control protocol should be designed in such a way that it can be used over +a reasonable variety of communication transport layers. In fact, it is quite +desirable if every major network protocol family that supports the standard X +protocol is also capable of supporting XDMCP, because the end result of XDMCP +negotiation will be standard X protocol connections to the display. +However, because the number of displays per host may be large, +a connection-based protocol appears less desirable +than a connection-less protocol. For this reason the protocol is designed +to use datagram services with the display responsible for sequencing and +retransmission. +</para> +<para> +<!-- .LP --> +To keep the burden on displays at a minimum (because display cost is not +a factor that can be ignored), it is desirable that displays not be required +to maintain permanent state (across power cycles) for the purposes +of the control protocol, +and it is desirable to keep required state at a minimum while the +display is powered on. +</para> +<para> +<!-- .LP --> +Security is an important consideration and must be an integral part of the +design.

A new network server, called a \fIDisplay +Manager\fP, will use XDMCP to communicate with displays to negotiate the +startup of X sessions. The protocol allows the display to authenticate the +manager. It also allows most of the configuration information to be +centralized with the manager and to ease the burden of system administration +in a large network of displays. +The essential goal is to provide plug-and-play +services similar to those provided in the familiar mainframe/terminal world. +</para> +<para> +<!-- .LP --> +Displays may be turned off by the user at any time. Any existing session +running on a display that has been turned off must be identifiable. This +is made possible by requiring a three-way handshake to start a session. If +the handshake succeeds, any existing session is terminated immediately and a +new session started. There is the problem (at least with TCP) that +connections may not be closed when the display is turned off. In most +environments, the manager should reduce this problem by periodically XSync'ing +on its own connection, perhaps every five to ten minutes, and terminating the +session if its own connection ever closes. +</para> +<para> +<!-- .LP --> +Displays should not be required to retain permanent state for purposes of +the control protocol. One solution to packets received out of sequence +would be to use monotonically increasing message identifiers in each message +to allow both sides to ignore messages that arrive out-of-sequence. For +this to work, displays would at a minimum have to increment a stable crash +count each time they are powered on and use that number as part of a +larger sequence number. But if displays cannot retain permanent state this +cannot work. Instead, the manager assumes the responsibility for permanent +state by generating unique numbers that identify a particular session and +the protocol simply ignores packets that correspond to an invalid session. +</para> +<para> +<!-- .LP --> +The Manager must not be responsible for packet reception. To prevent the +Manager from becoming stuck because of a hostile display, no portion of the +protocol requires the Manager to retransmit a packet.

The display can keep the protocol running as it will always know +when the Manager has received (at least one copy of) a packet.
