Hi All

I'll prepare one post about it in my blog, but in fact,what you have to do

1. Configure your xming and in flags you have to define "-ac". This will
define the xming to accept connection. Reopen your xming, case was running
2. Connect by putty your linux machine and type, export DISPLAY=<ip address
of your machine>:0
3. Try execute a graphical command like xclock, xterm, kterm ..., or the
oracle installer

Ps.: About connect directly without define the variable DISPLAY, it is
possible, but you have to do a little conf in putty.

Let'me know if you have doubts about it

B' Regards

Hi there,

Apologies in advance if this doesn't answer your question but there might
be a better way to reattach to an X session. In all the attempts to forward
x11 (where wasn't deactivated for security reasons) I found it to be
dreadfully slow and susceptible to network failure such as a laptop going
to sleep or hibernation. Or windows decided to reboot or similar mishaps.

In all these cases oui was practically unusable (slow) or didn't work at
all. The solution of my choice is either a silent installation in screen
(cool because it can be done so it is identical on all hosts) or if GUI was
needed then using vnc. Unlike x forwarding which always died on me if the
initial connection was lost, I could reliably reattach to running sessions
and resume where I was.

Oh and if you have a firewall simply forward port 590x and you have a SSH
encrypted connection as an added goody. Your vnc client then points to

Hope this helps,

The forwarding works. 'screen' is a linux utility. It lets you leave your
remote session and it keeps running on the server. Its like running nohup,
but you can do it with something interactive like sqlplus. Then reconnect
later. your session keeps running.

I am looking to see if anyone knows how to get x11 to work with screen. I
can re-attach to my unix session, but I think my x11 projection is gone.

Did you xhost + to allow the forwarding ?

*Subject:* Using Redhat utility 'screen' with oracle install GUI and
x11 forwarding

Redhat 6 64 bit clusterware install

xming run on laptop

I have to get behind a firewall, so I go to a specified unix server and
then execute

ssh -X oracle@<IP>

In putty I use

x11 forwarding

x display option: localhost:0.0

I do not set the DISPLAY parameter in unix since I am using x11
forwarding. So its a little different.

I ran screen, executed the server. Was able to get back into the server
and re-attach to my session.

How do I get back into the x11 forwarding of the GUI installer? I think
I did this a few years ago, but I can't remember how. I need to kick off
installs and leave, plus my VPN can drop me during the install.

I am re-attached to my screen session, but dont know how to get back
into the GUI installer.

anyone know?
