Setting Remote Display and X11 Forwarding Configuration
If you are on a remote terminal, and the local system has only one visual (which is typical), then use the following syntax to set your user account DISPLAY
environment variable:
Remote Display
Bourne, Korn, and Bash shells
$ export DISPLAY=hostname:0
C shell
% setenv DISPLAY hostname:0
For example, if you are using the Bash shell and if your host name is local_host
, then enter the following command:
$ export DISPLAY=node1:0
X11 Forwarding
To ensure that X11 forwarding does not cause the installation to fail, use the following procedure to create a user-level SSH client configuration file for Oracle installation owner user accounts:
-
Using any text editor, edit or create the software installation owner's
~/.ssh/config file
. -
Ensure that the
ForwardX11
attribute in the~/.ssh/config
file is set tono
. For example:Host * ForwardX11 no
-
Ensure that the permissions on
~/.ssh
are secured to the Oracle installation owner user account. For example:$ ls -al .ssh total 28 drwx------ 2 grid oinstall 4096 Jun 21 2020 drwx------ 19 grid oinstall 4096 Jun 21 2020 -rw-r--r-- 1 grid oinstall 1202 Jun 21 2020 authorized_keys -rwx------ 1 grid oinstall 668 Jun 21 2020 id_dsa -rwx------ 1 grid oinstall 601 Jun 21 2020 id_dsa.pub -rwx------ 1 grid oinstall 1610 Jun 21 2020 known_hosts
