一、总结过程记录
（1）、修改custom.conf
[root@xckydb ~]# vi /etc/gdm/custom.conf
--向xdmcp添加信息，把Enable=0改为Enable=1
（2）、修改Xaccess
[root@xckydb ~]# vi /usr/share/config/kdm/Xaccess
--把“#*#any host can get a login window”这行信息前#去掉
（3）、修改kdmrc
[root@xckydb ~]# vi /usr/share/config/kdm/kdmrc
--把Xdmcp下将Enable改为true（Enable=true）
（4）、重启系统
[root@xckydb ~]# reboot
（5）、查看177端口
[root@xckydb ~]# netstat -na|grep 177
--XDMCP服务对应的端口为177
udp 0 0 0.0.0.0:177 0.0.0.0:*
（6）、使用Xmanager软件Xbrowser实现远程桌面LINUX系统
包括配置文件的全部内容及操作截图，参考如下“详细过程记录”。
二、详细过程记录
1. 修改LINUX系统设置
（1）、修改custom.conf
[root@xckydb ~]# vi /etc/gdm/custom.conf
--向xdmcp添加信息，把Enable=0改为Enable=1
--custom.conf文件内全部内容如下
GDM Configuration Customization file.## This file is the appropriate place for specifying your customizations to the# GDM configuration. If you run gdmsetup, it will automatically edit this# file for you and will cause the daemon and any running GDM GUI programs to# automatically update with the new configuration. Not all configuration# options are supported by gdmsetup, so to modify some values it may be# necessary to modify this file directly by hand.## Older versions of GDM used the "gdm.conf" file for configuration. If your# system has an old gdm.conf file on the system, it will be used instead of# this file - so changes made to this file will not take effect. Consider# migrating your configuration to this file and removing the gdm.conf file.## To hand-edit this file, simply add or modify the key=value combination in# the appropriate section in the template below. Refer to the comments in the# /usr/share/gdm/defaults.conf file for information about each option. Also# refer to the reference documentation.## If you hand edit a GDM configuration file, you should run the following# command to get the GDM daemon to notice the change. Any running GDM GUI# programs will also be notified to update with the new configuration.## gdmflexiserver --command="UPDATE_CONFIG <configuration key>"## e.g, the "Enable" key in the "[debug]" section would be "debug/Enable".## You can also run gdm-restart or gdm-safe-restart to cause GDM to restart and# re-read the new configuration settings. You can also restart GDM by sending# a HUP or USR1 signal to the daemon. HUP behaves like gdm-restart and causes# any user session started by GDM to exit immediately while USR1 behaves like# gdm-safe-restart and will wait until all users log out before restarting GDM.## For full reference documentation see the gnome help browser under# GNOME|System category. You can also find the docs in HTML form on# http://www.gnome.org/projects/gdm/## NOTE: Lines that begin with "#" are considered comments.## Have fun![daemon][security][xdmcp]Enable=1</span>[gui][greeter][chooser][debug]# Note that to disable servers defined in the defaults.conf file (such as# 0=Standard, you must put a line in this file that says 0=inactive, as# described in the Configuration section of the GDM documentation.#[servers]# Also note, that if you redefine a [server-foo] section, then GDM will# use the definition in this file, not the defaults.conf file. It is# currently not possible to disable a [server-foo] section defined# in the defaults.conf file.#（2）、修改Xaccess
[root@xckydb ~]# vi /usr/share/config/kdm/Xaccess
--把“#*#any host can get a login window”这行信息前#去掉
改之前：
改之后：
--Xaccess文件内全部内容如下
# $XdotOrg: app/xdm/config/Xaccess,v 1.2 2004/04/23 19:54:43 eich Exp $# $Xorg: Xaccess,v 1.3 2000/08/17 19:54:17 cpqbld Exp $# $XFree86: xc/programs/xdm/config/Xaccess,v 1.4 2003/07/09 15:27:40 tsi Exp $## Access control file for XDMCP connections## To control Direct and Broadcast access:## pattern## To control Indirect queries:## pattern list of hostnames and/or macros ...## To use the chooser:## pattern CHOOSER BROADCAST## or## pattern CHOOSER list of hostnames and/or macros ...## To define macros:## %name list of hosts ...## To control which addresses xdm listens for requests on:## LISTEN address [list of multicast groups ... ]## The first form tells xdm which displays to respond to itself.# The second form tells xdm to forward indirect queries from hosts matching# the specified pattern to the indicated list of hosts.# The third form tells xdm to handle indirect queries using the chooser;# the chooser is directed to send its own queries out via the broadcast# address and display the results on the terminal.# The fourth form is similar to the third, except instead of using the# broadcast address, it sends DirectQuerys to each of the hosts in the list# The fifth form tells xdm which addresses to listen for incoming connections# on. If present, xdm will only listen for connections on the specified# interfaces and/or multicast groups.## In all cases, xdm uses the first entry which matches the terminal;# for IndirectQuery messages only entries with right hand sides can# match, for Direct and Broadcast Query messages, only entries without# right hand sides can match.#* #any host can get a login window## To hardwire a specific terminal to a specific host, you can# leave the terminal sending indirect queries to this host, and# use an entry of the form:##terminal-a host-a## The nicest way to run the chooser is to just ask it to broadcast# requests to the network - that way new hosts show up automatically.# Sometimes, however, the chooser can't figure out how to broadcast,# so this may not work in all environments.##* CHOOSER BROADCAST #any indirect host can get a chooser## If you'd prefer to configure the set of hosts each terminal sees,# then just uncomment these lines (and comment the CHOOSER line above)# and edit the %hostlist line as appropriate##%hostlist host-a host-b#* CHOOSER %hostlist ### If you have a machine with multiple network interfaces or IP addresses# you can control which interfaces accept XDMCP packets by listing a LISTEN# line for each interface you want to listen on.

The default is equivalent to the example shown# here using the Link-Local version to most closely match the old IPv4 subnet# broadcast behavior.## LISTEN * ff02:0:0:0:0:0:0:12b# This example shows listening for multicast on all scopes up to site-local## LISTEN * ff01:0:0:0:0:0:0:12b ff02:0:0:0:0:0:0:12b ff03:0:0:0:0:0:0:12b ff04:0:0:0:0:0:0:12b ff05:0:0:0:0:0:0:12b（3）、修改kdmrc
[root@xckydb ~]# vi /usr/share/config/kdm/kdmrc
--把Xdmcp下将Enable改为true（Enable=true）
--kdmrc文件内全部内容如下
# 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).

[root@xckydb ~]# reboot
（5）、查看177端口
[root@xckydb ~]# netstat -na|grep 177
--XDMCP服务对应的端口为177
udp 0 0 0.0.0.0:177 0.0.0.0:*
2. 使用Xmanager远程桌面
（1）、打开Xbrowser软件
（2）、进入Xbrowser后，会看到配置了177端口服务的机器自动识别出来了，双击打开，如下图：
（3）、弹出IP选择器，选择和虚拟机系统同IP段的IP地址，点击确定。
（4）、输入用户名、密码即可完成远程桌面登陆了，过程参考下面截图：
登陆后，远程桌面登陆成功，如下图所示：
至此，实验完成，实现了用Xmanager软件远程桌面LINUX系统的目的。
