How to connect with Secure Shell and launch a CDE session?

LAST MODIFIED DATE: February 16, 2004

VERSION: This applies to Exceed version 8.0+

PROBLEM:

How do you connect securely (ie) with Secure Shell and launch the CDE environment? You can not use Exceed in XDMCP mode because XDMCP uses UDP and not TCP.

SOLUTION:

You can use Xstart with Secure Shell as the start method. Here are the steps:

Launch Xstart.
Select Secure Shell as the Start Method.
Set the Secure Shell Profile to be used (in version V9.0 and higher).
Set the Host Type.
Enter the path to run an Xterm into the Command field, or use the Command provided by Xstart:
@(XTerm, method=stdappdb)
Note: Since this is a Secure Shell connection you do not need to include the display information in the command line.
Click Run, this will open a secure Xterm
At the prompt of the Xterm run /usr/dt/bin/Xsession

The CDE session will be launched and since it was started from a Secure Xterm, all the information for the CDE session will pass through the same tunnel.

Note: If the above works you can try using the following command line to Xstart to reduce the number of steps needed:

@(XTerm, method=stdappdb) -e /usr/dt/bin/Xsession

Note: The location of the xterm and Xsession is dependent on the host machine.

Here are some possible examples:

For Linux:
/usr/X11R6/bin/xterm -e /etc/X11/xdm/Xsession

For Solaris:
/usr/openwin/bin/xterm -e /usr/dt/bin/Xsession

For other Unix hosts:
/usr/bin/X11/xterm -e /usr/dt/bin/Xsession
