Using Remote Display
You can, of course, change both of these values if that is what your system
requires. Additional information about these scripts can be found in “Batch
Scripts” on page 43.
The Additional Options area lets you enter arguments that are sent to the
batch system. The options you add override options named in the batch
script.
You’re ready to launch. Do this by pressing the Launch Debug Session button.
Behind the scenes, a job is submitted that will launch the Server and
the Viewer when it reaches the head of the batch queue.
Setting Up Your Systems and Security
In order to maintain a secure environment, Remote Display uses SSH. The
Remote Display Server, which runs on the remote host, allows only RFB
(Remote Frame Buffer) connections from and to the remote host. No
incoming access to the Server is allowed and the Server can only connect
back to the Viewer over an established SSH connection. In addition, only
one Viewer connection is allowed to the Server.
As Remote Display connects to systems, you are asked to enter your password.
If you are allowed to use keyless ssh, you can simplify the connection
process. You should check with your system administrator to confirm that
this kind of connection is allowed and the ssh documentation for information
on generating and storing key information.
Here are three things that must occur before the Client can connect to the
remote host:
� If you use an LM_LICENSE_FILE environment variable to identify where
your license is located, you must insure that this variable is read in on
the remote host. This will be done automatically if the variable’s definition
is contained within one of the files read by the shell when Remote
Display logs in.
� ssh must be available on all nonWindows systems being accessed.
� X Windows must be available on the remote system.
Session Profile Management
The Client lets you save the information you enter. At a later time, you can
restore these settings by clicking on the profile’s name in the Session Profile
area.
The Client initially saves the information you first enter into a profile whose
name is what you entered in the remote host area. Figure 41 on page 42
shows two saved profiles.
After you click on a profile, the Client writes this previously saved information
into its text fields.
The four icons within the Session Profiles area are described in “Session Profiles
Area” on page 45.
