求助！关于f7利用xwindows管理远程主机

hxre

本机装的是f7,ip 172.16.3.89，远程服务器为redhat as4，ip 172.16.3.95 ,
redhatas4上已经配置了/etc/X11/gdm/gdm.conf的 [xdmcp] 、/etc/X11/xdm/Xaccess，以及/etc/X11/xdm/Xservers和/etc/X11/xdm/Xsetup_0的属性

我在f7上首先执行 xhost +
然后通过ssh登录到 redhatas4，执行 export DISPLAY=172.16.3.89:0.0
然后执行通过ssh在 redhatas4上执行 xclock
报错：
Error: Can't open display: 172.16.3.89:0.0

请问还需要配置或者检查什么地方么？f7本身要做什么配置么？

现在在f7上运行 X -quiet -query 172.16.3.95 可以登录到redhatas4，但是不是想要这样的效果阿..

我看oracle安装文档上，只需要在出现图形界面的时候输入相应命令，本机只会出现相应的窗口，而不是完全登录上...

解决拉！

1.1. Troubleshooting

Connection error is probably the most common problem you'll encounter. You may see some of the following messages if you encounter such error:

xclock: Cannot connect to X server local_client:0.0.
Check the DISPLAY environment variable or use `-d'.
Also use the `xhost' program to verify that it is set to permit connections from your machine.
Xlib: connection to "local_client:0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: local_client:0.0

A cause of such error is due to the firewall settings on the local machine. For this method to work, the remote machine needs to talk to the TCP port 6000 of the local machine. (In general, TCP port 6000+D for display D.) Make sure that the firewall does not block the port.

Another cause of error is due to the use of GDM on the local machine, . By default, GDM blocks the TCP communication required for this method. It is done so for security reason. If you know what you are doing, you can run gdmsetup to modify the setting. In Ubuntu, gdmsetup can be launched with Applications->System->Login Window. Select the [Security] tab and uncheck the option 'Deny TCP connections to Xserver'. If you want to modify the configuration file manually (which is not advisable), first find out where gdm.conf is located (usually under /etc/X11/gdm/ or /etc/gdm/). Then, modify (or create) gdm.conf-custom on the same directory to include the following setting:

[security]
DisallowTCP=false
