xhost + and trying to run graphical app
I have an oracle linux basic server updated.
I need to test and installation with an GUI but I cannot do it. I found a lot of information so I did this:
connect with putty on an ssh to my server oracle linux with it´s ip address 192.168.100.62
I did the connection with my desktop with it´s ip addresss 192.168.100.34
When connecting I did with oracle user and I export DISPLAY as
xhost + 192.168.100.34 but show me xhost: unable to open display ""
and of course did not let me run for example xclock Error: Can't open display:
I am a basic linux user but I like to learn, but I need how to configure my server oracle linux to run some GUI apps or installation
You need to have an x-server running on your desktop, in order to receive the redirected GUI output. I use xming. Like putty, it is free and lightweight.
Also, you don't need to fool with DISPLAY or xhost. Just configure you putty session to allow x-11 port forwarding.
I need to test and installation with an GUI but I cannot do it.
Install VNC server, a X Display Manager and xterm on server:
yum install tigervnc.x86_64 xorg-x11-twm.x86_64 xterm.x86_64
As the o/s user (e.g. grid or oracle) to run the GUI install as, run vncserver. Specify a password for accessing the desktop.
Now from your client PC, use vncviewer (free download from http://www.tightvnc.com/download.php) and connect to GUI desktop on the server.
