centos 5.4 xmanager 配置

在网上找了一点东西，但是貌似和真的centos不一样，所以这里自己来测试着做做这个配置：

[root@localhost X11]# ls -l

总计 80

drwxr-xr-x 2 root root 4096 2009-03-10 applnk

drwxr-xr-x 2 root root 4096 10-15 01:58 fs

-rwxr-xr-x 1 root root  947 2009-09-29 prefdm

drwxr-xr-x 2 root root 4096 2009-03-10 serverconfig

drwxr-xr-x 2 root root 4096 2009-03-10 sysconfig

drwxr-xr-x 2 root root 4096 10-15 01:41 twm

drwxr-xr-x 5 root root 4096 10-15 01:45 xinit

-rw-r--r-- 1 root root  547 2008-05-24 Xmodmap

-rw-r--r-- 1 root root  564 10-15 02:06 xorg.conf

-rw-r--r-- 1 root root  492 2008-05-24 Xresources

这里没有/etc/X11/gdm/gdm.conf这个文件。所以whereis一下，但是貌似位置不一样

[root@localhost X11]# whereis gdm.conf

gdm: /usr/sbin/gdm /etc/gdm /usr/share/gdm /usr/share/man/man1/gdm.1.gz

于是进入到/etc/gdm中

[root@localhost X11]# cd /etc/gdm/

[root@localhost gdm]# ls

custom.conf  locale.alias  PostLogin    PreSession           XKeepsCrashing

Init         modules       PostSession  securitytokens.conf  Xsession

发现这里也没有gdm.conf，不过根据以往经验.conf就是这个程序的设置程序，这里有两个就不妨打开一个：

比如 ：

[root@localhost gdm]# cat custom.conf

# 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 "

#

# 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

#

#

# NOTE: Lines that begin with "#" are considered comments.

#

# Have fun!

[daemon]

[security]

[xdmcp]

[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.

这下发现，这个文件就是我要的配置文件。先备份（备份操作很重要），再开始设置相应的选项：

编辑/etc/gdm/custom.conf,内容如下：

[daemon]

[security]
AllowRemoteRoot=true

[xdmcp]
Port=177

[gui]

[greeter]

[chooser]

[debug]

[servers]

然后重启桌面：gdm-restart

设置防火墙，在/etc/sysconfig/iptables文件中加入：

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 6000:6010 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 177 -j ACCEPT

重启防火墙：service iptables restart

在windows中启动Xmanager，就可以看到CentOS了。

在中启动启动Xstart，按下列提示输入：
Name: Xterm
Host: 192.168.1.4
procotol: SSH (setup port 为22)
User: xuys
Password: xuys1234

Execution Command可以填写/usr/bin/gnome-session --display=$DISPLAY,也可以填写  /usr/bin/xterm -display $DISPLAY 前者主要打开一个X桌面,后者只是打开一个xterm.根据需要自行选择.

点击“Save”，保存。
点击“Run”运行Xmanager。
