(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

--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.  You can additionally list
# one or more multicast groups after each address to listen on those groups
# on that address.
#
# If no LISTEN is specified, the default is the same as "LISTEN *" - listen on
# all unicast interfaces, but not for multicast packets.  If any LISTEN lines
# are specified, then only the listed interfaces will be listened on.
#
# IANA has assigned FF0X:0:0:0:0:0:0:12B as the permanently assigned
# multicast addresses for XDMCP, where X 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.  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

--Xdmcp下将Enable改为trueEnable=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). Note that the backslashes
# need to be doubled because of the two levels of quoting.

#AutoLoginEnable=true
# The user to log in automatically. NEVER specify root!
#AutoLoginUser=fred
# The password for the user to log in automatically. This is NOT required
# unless the user is to be logged into a NIS or Kerberos domain. If you use
# it, you must "chmod 600 kdmrc" for obvious reasons.
#AutoLoginPass=secret!
# The session for the user to log in automatically. This becomes useless after
# the user's first login, as the last used session will take precedence.
#AutoLoginSession=kde
# If "true", the auto-login is truly automatic, i.e., the user is logged in
# when KDM comes up. If "false", the auto-login must be initiated by crashing
# the X-server with Alt-Ctrl-BackSpace. Default is true
#AutoLogin1st=false

# Greeter config for 1st local display

(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:*

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。
