使用XManager连接OEL 6

客户的服务器估计是因为VMware虚拟机的原因，无论怎么样都没法通过VNC连接。要在机器使用图形界面安装Oracle软件，只能退求其次使用XManager连接了。操作步骤如下：
1.改变系统的runlevel到5.
打开/etc/inittab，确认初始的runlevel为5
id:5:initdefault:
2.打开XDMCP
【使用GDM】：
打开”/etc/gdm/custom.conf“，把[xcmcp]节设置为1
[xdmcp]

Enable=1

【使用KDM】：
打开”/usr/share/config/kdm/Xaccess“文件，下除下列行前面的”#“号：
#* #any host can get a login window ==>
* #any host can get a login window

 打开”/usr/share/config/kdm/kdmrc“文件，把[xdmcp]节设置为true
 [xdmcp]
Enable=true

3.确认防火墙的UDP端口177打开；
4.重启服务器并使用Xmanager进行连接。
