今天在oracle linux上配置了一下X manager 和vnc，是第一次配置vnc，vnc配置要比X manager简单许多这里记录一下：
—- X manager 配置：
[xdmcp]# Distributions: Ship with this off. It is never a safe thing to leave# out on the net. Setting up /etc/hosts.allow and /etc/hosts.deny to only# allow local access is another alternative but not the safest.# Firewalling port 177 is the safest if you wish to have xdmcp on.# Read the manual for more notes on the security of XDMCP.Enable=true
用vi编辑gdm.conf 进入后键入/xdmcp查找字符串xdmcp “n”是搜索下一句，这样就能快速的定位到xdmcp项
2.修改/etc/X11/xdm/xdm-config文件，将DisplayManager.requestPort: 0注释掉
! SECURITY: do not listen for XDMCP or Chooser requests! Comment out this line if you want to manage X terminals with xdm!DisplayManager.requestPort: 0
3.修改/etc/X11/xdm/Xaccess文件 #* #any host can get a login window 去掉此行首位的#
# right hand sides can match.#* #any host can get a login window## To hardwire a specific terminal to a specific host, you can
4. 如果有防火墙，请打开177的端口
ok！配置完后用X manager进入吧
—-VNC 配置
1.检查rpm包是否安装
[oracle@niuge ~]$ rpm -qa|grep vncvnc-server-4.0-11.el4vnc-4.0-11.el4
只要有第一个vnc-server-4.0-11.el这个就足够，这是服务端运行程序。如未安装，请安装
2.安装好后运行 vncserver
[test@niuge ~]$ vncserverYou will require a password to access your desktops.Password: Verify: xauth: creating new authority file /home/test/.XauthorityNew ‘niuge:3 (test)’ desktop is niuge:3Creating default startup script /home/test/.vnc/xstartupStarting applications specified in /home/test/.vnc/xstartupLog file is /home/test/.vnc/niuge:3.log
会提示你输入登录密码，同时会给你提示，记住这个”:3″ 这是你vnc客户端登录时候要用到的，我机器已经开启了2个，所以这个是:3
3.在windows机器上装好vnc客户端，装好后运行客户端，输入方式如下图所示
